STUDY AND ANALYSIS OF SILTATION AT NAHRE GHASR FISHERY PORT

The discharge of Arvand River and tidal currents affect the large siltation at Nahre Ghasr Fishery Port, located at the Nahre Ghasr channel, the Persian Gulf. Using 2DH and 3D numerical models, the flow pattern at the channel was investigated to study the details of siltation problem. The local model was calibrated by the measured data of water surface and suspended sediment rate. The main flow mechanisms that can affect the rate of siltation including the horizontal exchange, the vertical exchange and tidal filling, were analyzed. The study showed that tidal filling plays the dominant role on the sedimentation at Nahre Ghasr channel. Different scenarios were also examined for reducing the siltation rate at the port.

Identification of Fishermen Household’s Adaptive Capacity in Responding to Climate Change Impacts (A Case Study of Muncar District, Banyuwangi Regency, Indonesia)

Climate change affects the uncertainty of oceanographic condition that has an impact on the marine fisheries, such as changes in fishing areas, winds, and extreme waves. As an archipelagic country, the majority of Indonesian cities are in the coastal area whose the community’s livelihood depends on marine fishery activities. Climate change impacts the coastal community who engages in fishery activities are now being vulnerable group towards climate change. This condition is also experienced by fishermen in Muncar District, the second biggest fishery port in Indonesia. It is necessary to enhance fishermen household’s adaptive capacity which is the key to region’s resilience. This research focuses on adaptive capacity assessment by formulating criteria and indicators based on the expert's theories review. The method that is used in this research is statistic descriptive based on a questionnaire which distributed to 120 households samples. This research also views perception of fishermen on climate change impacts and on how Local Government Units (LGUs) and Community Organizations (COs)support the increase of fishermen household’s adaptive capacity. The result of the assessment showed that 56% of households have ‘medium’ adaptive capacity, 34% of them are in ‘low’ adaptive capacity, and 10% households are in ‘high’ adaptive capacity. The LGUs and COs gives a high endorsement to households to increase their adaptive capacity. The result of this study can be taken into consideration in formulating the strategies to enhance fishermen household’s adaptive capacity in order to realize the resilient fishermen households socially and economically.

A new GIS-based tsunami risk evaluation: MeTHuVA (METU tsunami human vulnerability assessment) at Yenikapı, Istanbul

Istanbul is a mega city with various coastal utilities located on the northern coast of the Sea of Marmara. At Yenikapi, there are critical vulnerable coastal utilities, structures, and active metropolitan life. Fishery ports, commercial ports, small craft harbors, passenger terminals of intercity maritime transportation, waterfront commercial and/or recreational structures with residential/commercial areas and public utility areas are some examples of coastal utilization that are vulnerable to marine disasters. Therefore, the tsunami risk in the Yenikapi region is an important issue for Istanbul. In this study, a new methodology for tsunami vulnerability assessment for areas susceptible to tsunami is proposed, in which the Yenikapi region is chosen as a case study. Available datasets from the Istanbul Metropolitan Municipality and Turkish Navy are used as inputs for high-resolution GIS-based multi-criteria decision analysis (MCDA) evaluation of tsunami risk in Yenikapi. Bathymetry and topography database is used for high-resolution tsunami numerical modeling where the tsunami hazard, in terms of coastal inundation, is deterministically computed using the NAMI DANCE numerical code, considering earthquake worst case scenarios. In order to define the tsunami human vulnerability of the region, two different aspects, vulnerability at location and evacuation resilience maps were created using the analytical hierarchical process (AHP) method of MCDA. A vulnerability at location map is composed of metropolitan use, geology, elevation, and distance from shoreline layers, whereas an evacuation resilience map is formed by slope, distance within flat areas, distance to buildings, and distance to road networks layers. The tsunami risk map is then computed by the proposed new relationship which uses flow depth maps, vulnerability at location maps, and evacuation resilience maps.

So that data from the catches of fishermen willnot be sould to penyambang as data the basis for determining the policy is difficult to know and retribution for PAD port no. Average profit businesses penyambang vessel during fishing season is Rp. 2.773.611,00 per month while the crew (ABK) get Rp.1.386.806, 00 per month and crew still above the local minimum wage (UMR) South Kalimantan Province of Rp. 1.337.500.00. Fishing harbor in the village of Muara Kintap, Tanah Laut District as district fisheries economy still needs a better development strategy so that the presence of the ship penyambang can contribute to Improved Income (PAD) Kintap Estuary Fishery Port.

Site Selection of Reference Tidal Station for National Height Datum in Taiwan

AbstractNational vertical data are mostly referenced to a tidal level of one or more tidal stations. The Keelung tidal station has been serving as the reference tidal station of the Taiwan National Height Datum for more than one century; all orthometric height in Taiwan is zeroed to the mean sea level (MSL) of an astronomical period of this station. A monument of the Taiwan height origin was established nearby, but due to construction, the height origin was relocated to the newly built National Museum of Marine Science and Technology in Badouzi. This article documents the search for an improved definition of the tidal reference for height origin in Taiwan. The selection criteria identified include geological stability; sufficient depth of water; limited influence from nontidal effects, such as passing vessels; and proximity to the monument of height origin. As part of the preliminary assessment, a tidal station was established at the nearby Cheng-Bin fishery port. The authors performed tidal comparisons o...

Method for Quick Assessment of Caisson Breakwater Failure due to Tsunamis: Retrospective Analysis of Data from the 2011 Great East Japan Earthquake and Tsunami

Given the importance of ports to immediate disaster relief operations after a major tsunami, breakwaters are necessary to sustain a minimum level of functionality required to carry out port operations. However, most breakwaters that protect fishery or industrial ports are not designed to withstand a tsunami. For this reason, many of these breakwaters were destroyed by the 2011 Great East Japan Earthquake and Tsunami. However, some breakwaters withstood the tsunami, which facilitated the rapid resumption of port operations. In this study, 67 ports were investigated by using satellite images to identify the percentage of breakwaters that suffered damage due to the 2011 tsunami and how the tsunami height and breakwater width influenced the degree of breakwater damage. Because tsunami heights were not measured at the breakwaters, they were estimated by interpolating the data observed at nearby locations with a Gaussian weighting function at a reasonable accuracy. Possible drawbacks of this simplified method are also discussed because a certain degree of estimation error is inevitable. Breakwaters less than 8 m wide were quantitatively demonstrated to inevitably experience extensive damage when the tsunami height exceeded 14 m. In contrast, breakwaters that were more than 14 m wide, exposed to tsunami heights of less than 6 m, or both were not greatly damaged. An examination of the effectiveness of armor blocks also revealed that their placement could substantially reduce breakwater damage due to a tsunami. The results suggest a simplified method, particularly for assisting local fishery administrators or other authorities concerned, to practically estimate the risk of a port suffering damage because of future tsunamis. The proposed method should contribute to prioritizing the protection of ports in order of their likelihood of failure.

MODELLING OF SEDIMENT TRANSPORT IN BERIS FISHERY PORT

In this paper, the large amount of sedimentation and the resultant shoreline advancements at the breakwaters of Beris Fishery Port are studied. A series of numerical modeling of waves, sediment transport, and shoreline changes were conducted to predict the complicated equilibrium shoreline. The outputs show that the nearshore directions of wave components are not perpendicular to the coast which reveals the existence of longshore currents and consequently sediment transport along the bay. Considering the dynamic equilibrium condition of the bay, the effect of the existing sediment resources in the studied area is also investigated. The study also shows that in spite of the change of the diffraction point of Beris Bay after the construction of the fishery port, the bay is approaching its dynamic equilibrium condition, and the shoreline advancement behind secondary breakwater will stop before blocking the entrance of the port. The probable solutions to overcome the sedimentation problem at the main breakwater are also discussed.

Assessment of the Effectiveness of General Breakwaters in Reducing Tsunami Inundation in Ishinomaki

The 2011 Great East Japan Earthquake and Tsunami caused devastation all along the coast of eastern Japan. Ishinomaki City was one of the most severely damaged municipalities, though the height of the tsunami in this city was smaller than that in Iwate and northern Miyagi. A large difference in the extent of building damage was found comparing two areas of Ishinomaki: one not protected by breakwaters, and the other behind the breakwaters of a large Fishery port. In this paper, the authors perform numerical simulations to determine whether these general breakwaters, which were designed not to block tsunamis but wind waves, reduced the tsunami's energy and contributed to a reduction in inundation of the areas behind the port. Before assessing the effectiveness of breakwaters against tsunamis, simulated inundation heights in each of these two areas were compared with heights measured by The 2011 Tohoku Earthquake Tsunami Joint Survey Group. It was found that a simulation with larger Manning's n value (n = 0.30) can evaluate inundation more precisely than when this value is small (n = 0.06), as often used by Japanese coastal engineers. Comparing the region protected by breakwaters with the unsheltered area, the results of a 2D shallow water equation model do not show a significant difference in inundation mainly because the tsunami intrudes through the openings in the breakwater and fills up the port basin with seawater in a very short time. Therefore, the effectiveness of general breakwaters in reducing tsunami impact should not be overestimated. However, a hypothetical study shows that water levels could be greatly reduced if the port were fully enclosed by breakwaters. This implies that a port could substantially reduce tsunami inundation if the breakwater openings were equipped to be closed before tsunami arrival. The authors also demonstrate that the difference in the extent of building damage in the two areas of Ishinomaki considered can be explained by the difference in drag forces due to the topography as well as the difference in land use, rather than by the presence of breakwaters.

Redescription of Parabrachiella bera (Copepoda: Siphonostomatoida: Lernaeopodidae) Parasitic on Parajulis poecilepterus (Actinopterygii: Perciformes: Labridae) from Korea

Abstract Parabrachiella bera (Yamaguti, 1939) is redescribed based on newly collected material from multicolorfin rainbowfish, Parajulis poecilopterus, landed at Wando fishery port on the southern coast of Korea. Although some differences were observed between the original description and the specimens examined in this study, these differences do not warrant a change in the taxonomic status of this species. Parabrachiella bera bears some resemblance to Parabrachiella incurva Shiino, 1956, but differs from it in details of the trunk and genital processes. Key words: Parasite, Redescription, Copepoda, Parabrachiella bera , Parajulis poecilopterus Introduction The family Lernaeopodidae Milne Edwards, 1840 is the largest group of parasitic copepods, with a long history of synonymies, misidentifications, and status changes among its members (Kabata, 1979). Lernaeopodid copepods currently include about 267 valid species (Boxshall and Halsey, 2004; Boxshall and Walter, 2012); they are most widely adjusted to parasitism (Kabata, 1986) and are highly host-specific (Pias-ecki et al., 2010). The genus

Evaluation of Adequacy Fishery Port Infrastructure (Case Study on Fishery Port Mimbo Situbondo)

Fishery Port City Beach is located in the district of Situbondo Banyu Putih which is approximately 50 km from the city center. Exact location of the fishery port in the district directly adjacent to the Banyu PutihBanyuwangi industrial plant which contained fish canning factory in the district Muncar.In development ,thisport functions not only as a fishery port but also, as the crossing place to theSepudi island which is included of Madura district. Different from the original plan, transportation within the port has changed. Reserved parking area no longer function optimally. So that needs to be addressed and the need for further study are: to analyze the adequacy of the pier and parking lot, and to evaluate the adequacy of the road in the hinterland. From the results, we get few things: The need for the loading dock and mooring for a boat the size of the existing less or more than 10 GT still be fulfilled properly. Unloading dock for ship size is less or more than 10 GT still be met but overload jetty mooring for vessels up to 254% for vessel with size of more than 10 GT and 128% for vessels less than 10 GT size. By changing the way the mooring of vessels dilated / transverse require less space, so the ship mooring space requirements can be fulfilled until 2016. The adequacy of existing parking space is available for cars and trucks only and can provide for parking requirement. The number of vehicles entering the port increased so that parking spaces be overloaded so it is need to provide parking spaces for motorcycles and pick-up. By utilizing the tip of the breakwater area for motorcycle parking space (688 m) with a pattern of two sides and the base of the breakwater area for car parking (650m) with a pattern of one side and a parking area that has been available previously for the truck and pick-up, parking space requirements can be fulfilled. Adequacy Road at Hinterland area with increasing number of vehicles in 2016, so the level of service drops to C but still decent. By widening the ring road towards Situbondo according to standard (7 m), it can be an alternative for heavy vehicles which go to Situbondo.

Genetic identification of Carcharhinus sharks from the southwest Atlantic Ocean (Chondrichthyes: Carcharhiniformes)

Sharks of the genus Carcharhinus exhibit subtle morphological differences that are difficult to observe because of the common practice of head and fin removal, making species identification challenging. A total of 317 sharks, commonly called ‘cação-baia’ (large individuals) or ‘machote’ (small size) in Brazil, were captured by the tuna fleet at the Santos and Guarujá fishery ports on the southeastern coast of Brazil and identified at the species level by multiplex PCR. The Internal Transcribed Spacer 2 region of ribosomal DNA was amplified using universal primers, and species-specific primers were used for some of the Carcharhinus species. A total of 313 shark carcasses were directly identified by multiplex PCR. Four carcass samples did not amplify; therefore, the partial COI sequences were used to confirm their taxonomic identity. The results show that more than one species was being traded under the same commercial designation, including some Carcharhinus species that are under protection by federal legislation. Such species misidentification directly affects the long-term sustainability of sharks.

Three-dimensional tsunami runup simulation for the port of Koborinai on the Sanriku coast of Japan

Kim, D.C., Kim, K.O., Pelinovsky, E., Didenkulova, I. and Choi, B.H., 2013. Three-dimensional tsunami runup simulation for the port of Koborinai on the Sanriku coast of Japan.The huge tsunami generated by the earthquake that occurred off the Pacific coast of Japan at 14:46 JST (05:46 UTC) on Friday, 11 March 2011 produced a maximum runup of 40 m on the east coast of Japan. The earthquake triggered extremely destructive tsunami waves up to 37.9 m in height that struck Japan minutes after the quake. Koborinai is a tiny fishery port located north of Miyako City in the Iwate Prefecture. A survey team from the University of Tokyo Earthquake Research Institute (ERI) found high water marks and other evidence of a gigantic wave at the port of Koborinai. The port is on low land sandwiched between two mountains. A joint survey team from ERI-Sungkyunkwan University (SKKU) and Korea Ocean Research & Development Institute (KORDI) visited again and surveyed the site in detail. The 3D Princeton Ocean Model was applied to describe the propagation and runup of the tsunami on the Japanese coast. The numerical simulation results obtained were in satisfactory agreement with observations made in the general area, except those made in many v-shaped valleys along the northern Iwate coast. The extremely high runup of tsunami waves at the port at Koborinai were successfully reproduced by numerical simulation through stepwise refinement of the spatial scale using multi-nesting and consideration of the vertical acceleration of flow along steep slopes using a CFD model to solve the Reynolds-averaged Navier–Stokes (RANS) equations. The velocity field was also computed, and the simulation results show that the water flow that climbed the coast possessed a strong vertical velocity component.

Behavior of the 2011 Tohoku Earthquake Tsunami and Resultant Damage in Tokyo Bay

The behavior of the 2011 Tohoku earthquake tsunami in Tokyo Bay and its resultant damage to the coasts are studied using a field survey, an analysis of observed tsunami wave profiles and numerical hindcasting using FVCOM and Delft3D-Flow. The field survey reveals that the tsunami caused several fishery ports to overflow, and unexpectedly large inundation and run-up heights of 2.84 m and 2.91 m were recorded in Funabashi Fishery Port and Shin-Futtsu Fishery Port, respectively. Examining the observed tsunami wave profiles, the tsunami wave entered the bay with a maximum height of approximately 0.9 m for the second wave and a period of approximately 60 min, propagating along the major axis of the bay with almost uniform height. Numerical hindcasting results using both the models are fairly consistent with the measurements, revealing that the tsunami wave heights are locally amplified in ports because of wave reflection, water accumulation due to their narrow and enclosed shape, and, to some extent, the harbor resonance. Heavy damage to seaweed farming was also observed, especially around the Futtsu Cape and the northern part of the Banzu tidal flat, which numerical analysis attributes to the appearance of large hydraulic resistance on seaweed net.
