Using bottom outlets for drain and regulation of water level in reservior has significant importance in performance mahagment of dam. Amount of service and emergency gates opening have important role in pressure, velocity and discharge coefficient variations and finally dam performance. In the present research, flow aeration between emergency and service gates was studied with different hydraul...

To determine the throughput of automatic gate flushing device, which is part hydraulic water level controller with flexible working bodies, developed by author together Ya.V. Bochkarev, experimental studies were conducted. They carried out method physical modeling model and nature on an installation, installation two models shutter: a) a fixed angle inclination pressure board, b) shutter in for...

To eliminate the shortcomings of known hydraulic autoregulators water level, together with Ya. V. Bochkarev, we developed a design autoregulator level flexible working bodies, combined an automatic gate for washing sediments, which provides discharge floating bodies and bottom sediments in front partition structure. ensure stable vibration-free operation this hydro-automatic controller, task wa...

A range of continental-scale soil datasets exists in Europe with different spatial representation and based on different principles. We developed comprehensive pedotransfer functions (PTFs) for applications principally on spatial datasets with continental coverage. The PTF development included the prediction of soil water retention at various matric potentials and prediction of parameters to ch...

This paper examines the problem of routing known water demands through gate-controlled, open-channel irrigation delivery systems. Volume-compensation principles were used to route multiple demands in multiple-pool canal systems. The volume-compensation method schedules each demand change individually under the assumption of a series of steady states and superimposes the individual results. Volu...

Hydraulic jump used to dissipate excessive kinetic energy in natural water ways since the down of time. Screens fixed stilling basin control hydraulic location, depth and length from four decades ago. In this study, screens with a constant height different widths same screen relative area (Ar=0.285) were located behind gate at distance 10 cm tested under wide variance conditions submerged jump....
