Soil use and occupation alter the physicochemical biological processes of aquatic ecosystems. Urban streams are fundamental components macro-drainage system cities; however, with advance urbanization, most modified to point that they no longer recognized as but sewage receptors. Physical diagnosis monitoring water quality essential understand trophic state these ecosystems in relation environme...

Abstract Intensification of extreme rainfall-runo events in arid and semi-arid regions because climate change induce the water erosion that contributes considerably to loss vegetal layers soils reduce storage capacity dams by silting transported sediments from watershed impoundment. This paper aims at proposing means for protecting Mghila dam against identification delimitation vulnerable areas...

Abstract In river mouths and coastal areas, sediment carried by water flows often clogs the estuaries causes silting lagoons, impacting prevalence of coral disease. Ten traps were installed in 25 cm from bottom to record data for 21 days Kawal River. Oceanographic current flow collected using CTD a Current meter Eulerian method with depth interval installation 0.25 0.75 surface. The Underwater ...

Sedimentation causes land accretion, silting river water, lagoon, and mangrove degradation. The current study aims to analyze the potential impact of sedimentation toward lagoon ecosystem in Segara Anakan Lagoon. research methods used mapping analysis, total suspended solid analysis (TSS), rate biodiversity covering. result showed that (1) value TSS between 0.25-1,16 g L-1 (2) sediment flux 6,8...

The domain of Chantilly (Oise, France) includes a castle and garden, both dating from the eighteenth century, which are seen as important legacies France’s history. Nowadays, 2.5 km canal that runs through is subject to phenomenon silting, leading accumulation sediments within linked proliferation algae, has dissuasive effect among visitors. HEC-RAS software (Hydrologic Engineering Centers Rive...

All over the world, dam managers are constantly confronted with siltation of reservoirs. This natural phenomenon represents a menace to safety dam; because sediments deposited amplifies load applied and shut off dam’s bottom outlet. It also reduces usable capacity reservoir degrades quality water stored (pollution, eutrophication, turbidity, etc.). In arid semi-arid countries like Morocco, de-s...

This study aimed to analyze the pattern of sediment transport distribution plankton and fishing ground in estuary KamparRiver. used survey methods, sample was obtained field are considered represent Kampar River estuary. Then sampling results form TSS, brightness, temperature, salinity, pH, flow velocity descriptively analyzed discussed with reference data interpretation method by using mathema...

Percut Village is one of the villages located on East Coast North Sumatra which directly opposite waters Malacca Strait so that main livelihood villagers as fishermen. During pandemic, government has implemented a Large Scale Social Restriction policy an impact social status community, such limited fishing activities have resulted in decrease selling price caught fish. In addition, silting sedi...

The segmental joints are the weak parts of immersed tunnel structure, and their deformation characteristics closely correlated with waterproof behavior structural safety whole tunnel. In order to study in this paper, E13 pipe section natural foundation an Hong Kong-Zhuhai-Macao Bridge is taken as research object, model test carried out. similarity ratio prototype determined according actual eng...
