Field Research Methods And Some Results For Distribution Of Suspended Sediment In Flow Constrained By Transverse Dams, M.R. Bakiev, K.T. Yakubov, O.M. Matkarimov, Z.B. Dovlatov
Irrigation and Melioration
The article presents methods for determining the main parameters of flow of medium hydraulic size sediment, turbidity, sampling methods in field and the instruments used for sampling, methods of processing the samples in laboratory. Methods for setting sections and gage points and conducting field and laboratory research have been developed for flow deformed by blank and through flow transverse dams, water surface longitudinal and transverse slope takes place in the flow constrained by transverse dams, changes in suspended sediment distribution occur inversely. Location of sections for sampling is determined in the article: in the headrace –beyond dam influence zone, maximal …
Design Dimensions Of Flow In Compressed Flow Beyond Combined Dikes, O. Kodirov, О. Хаlimbetov
Design Dimensions Of Flow In Compressed Flow Beyond Combined Dikes, O. Kodirov, О. Хаlimbetov
Irrigation and Melioration
The experimental research has shown that the kinematic pattern of flow deformed by combined structures (core part is blank and made of local materials, and the head part is made of piles), and it is more complicated than usual, although the qualitative flow schemes have much in common. The flow has the zones of backup, compression and spreading. Compression zone is discussed in the article, and the largest transverse and longitudinal drops in elevation and velocity are observed in this zone, therefore theoretically it is very difficult to set the main design dimensions of flow in this zone. Therefore, the …
