Historical Changes and Optimization Measures of Rural Water Conservancy Projects in the Context of Rural Revitalization

New China's water conservancy construction has its own development process, stages and characteristics, and the dynamics of development are related to the national policies and institutional arrangements of the time. The most effective manifestation of the "collectivization" of "people", in other words, "organization", in the first 30 years was the construction of farmland water conservancy. After the rural reform and before the tax reform, the construction of farmland water conservancy became a "peasant burden". In China at the time, there was no real reform, and it was difficult to have peasant-organized water conservancy without the ties of power and grassroots social management, so it was extremely important to have a holistic national top-level design and focus.

A Discussion on Adaptive Applications of Some Chinese Design Codes in Guinea and Localization of Flood Standards

Chinese engineering team participated in the construction of several water conservancy and hydropower projects in areas which have differences in climate characteristics from China. Due to a lack of hydrological and climatic data and the absence of systematic design specifications in these areas, considering construction safety, most of the Chinese designs and constructions are based on the extreme values with the Chinese design codes. The S Project in Guinea established a rainfall-runoff model through open-source remote sensing satellite precipitation data and limited hydrological station measured runoff data，allowing to refine local hydrological data. Based on these data series, it was then possible to calculate flood control standards with more local hydrological characteristics in order to promote the progress of the project scientifically. In addition, combining the refined discharging curve of the outlet hole with the latest arc gate online monitoring technology, and the joint dispatch with the downstream hydropower station, permitted that the downstream K Hydropower Station created historic power generation in 2019 with significant economic and social benefits.

Effectiveness of soil and water conservation structures in increasing community perception and controlling erosion and sedimentation

The increasing frequency of floods and landslides has prompted the Ministry of Environment and Forestry to intensify the construction of soil and water conservation (SWC) structures in various watersheds in Indonesia. However, the evidence on how the high-cost measure can effectively increase community perception and participation while controlling erosion and sedimentation is still limited. For this reason, this preliminary research was conducted in 2019 to observe community perception and assess the effectiveness of the SWC structures in controlling gully erosion and sedimentation. The activities carried out in the Jeneberang and Lisu Sub Watershedsconsisted of two parts: 1) social and economic data collectionand 2) observing the effectiveness of the SWC structures in controlling sedimentation. Based on the socio-economic survey, respondents in the Jeneberang showed a better understanding and higher incomes than respondents in the Lisu Sub Watershed, despite their lowereducation levels.These phenomena relateto the length of time the community has learnedfrom surrounding examples and the applied SWC techniques on their land.In terms of the effectiveness of SWC structures, more than half of the retaining dam and gully plug capacityhad been filled with sediment in just oneyear after construction and is expected to be full at the end of the rainy season.The leadingcause is the high erosion of the tillage area on both sides.As a suggestion, agricultural land in the catchment area needs to be managed by applying SWC techniques according to site conditions through incentives given to landowners.
