Abstract
Sulaibikhat Bay is situated along the northern coastline of Kuwait. It occupies the southwestern part of Kuwait Bay, between latitudes 29° 19ʺ and 29° 24ʺ north and longitudes 47° 50ʺ and 47° 55ʺ east, and covers a total area of about 45 km2. The lagoon bay is a shallow (7-8 m) tide-dominated embayment with a very soft muddy flat basin. It has a simple bottom topography, with a maximum water depth of about 8 m. The main objectives of this study is to delineate the water quality of Sulaibikhat Bay, to study the input of anthropogenic activities on the water quality, to recommend methods to improve water quality of the bay and to study the sediment and their heavy metals contents. About 15 marine water and 15 sediment samples were collected along the Sulaibikhat Bay. The samples were analyzed chemically for Total Petroleum Hydrocarbons, Trace Metals, and Total Organic Carbon. Also Biological Oxygen Demand, Chemical Oxygen Demand, and physically analyzed for Dissolved Oxygen, temperature, salinity, PH, Conductivity and nutrient levels. Data analyses for sediment and water reveal that the level of contamination is within the international standard however there are some higher reading of trace metals and other chemicals from the outlets of the power station more than the inlets. As, two sources or large input of trace metals in the coastal water of Sulaibikhat Bay are suggested in this study namely; estuarine fluviatile source of Shatt Al-Arab trace metal rich and dust fallouts.
Highlights
Sulaibikhat Bay is a part of the large Kuwait Bay (Figure 1), mainly formed of soft sediments and shallow depth which has weak currents and low wave energy [1]
The study focuses on update of environmental profile of Sulaibikhat Bay and to evaluate the anthropogenic impacts on its water quality and sediments
There are several out falls along the Sulaibikhat Bay: the Al-Ghazali out let, Al-Jahara out let, Entertainment city out let, Hospital out let and Doha Power Station east and west out lets
Summary
Sulaibikhat Bay is a part of the large Kuwait Bay (Figure 1), mainly formed of soft sediments and shallow depth which has weak currents and low wave energy [1]. The lagoon bay is a shallow tide-dominated embayment with a very flat basin [2]. It has simple bottom topography, with a maximum water depth of about 8 m. The most important features are the large extensive muddy tidal flats (20 km2) and the main tidal channel. The study focuses on update of environmental profile of Sulaibikhat Bay and to evaluate the anthropogenic impacts on its water quality and sediments. Hydrodynamics of the bay is very weak and is tide dominated. There are several out falls along the Sulaibikhat Bay: the Al-Ghazali out let, Al-Jahara out let, Entertainment city out let, Hospital out let and Doha Power Station east and west out lets
