Wall-jet flow is an important flow field in hydraulic engineering, and its applications include flow from the bottom outlet of dams and sluice gates. In this paper, the plane turbulent wall jet in shallow tailwater is simulated by solving the Reynolds Averaged Navier-Stokes equations using the standard turbulence closure model. This study aims to explore the ability of a time splitting method ...
Logjams with a gap at the bed form naturally in small channels and are used engineering practice to maintain river connectivity base flow. Limited understanding of jam's effect on backwater rise flow velocity limits assessment geomorphic ecological impacts natural logjams, design restoration interventions, representation flood models. The distribution through beneath jam satisfies two-box, mome...
All methods of combating the flooding populated areas are directly related to execution significant volumes earthworks, construction special structures, and therefore require comprehensive analysis substantiation selection most economically feasible affordable project options during design.But analyzing main protecting territory settlements from flooding, it should be noted that even with their...
Abstract The decrease in channel capacity can cause sedimentation at the bottom of and condition lining is damaged so that seepage / leaks occur buildings sluice gates do not function properly. This study aims to analyze concentration sediment on flow velocity. Measurements were carried out field observe conditions detail related velocity concentration. research was Rappang Main Channel from Up...
With the development of China’s social economy and science technology, all aspects construction are also growing rapidly, water conservancy project is one very important infrastructures in China, for promoting technology has a positive significance. promotion number projects been greatly improved. At present, different sizes, large small, being carried on continuously. vigorous project, higher ...
The south arm of the Mondego estuary, located in the central western Atlantic coast of Portugal, is almost silted up in the upstream area. So, the water circulation is mostly driven by tides and the tributary river Pranto discharges. Eutrophication has been taking place in this ecosystem during last twelve years, where macroalgae reach a luxuriant development covering a significant area of the ...
