Irrigation and Melioration

Abstract

The design of the route when regulating riverbeds, the direction of the flow to the point of water intake will require solving some issues, including the amount of deviation of the dynamic axis of the flow, constrained by regulatory structures. The main purpose of this work is to develop a method for calculating the deviation of the dynamic axis of a flow that is one-way constrained by a combined dam, then through part of which is made of tetrahedra. The problem is realized using the Varignon theorem and the flow conservation equation written for the streamlines where the household state of the upstream flow and the tightness gate are preserved. The concept of the flow coefficient as the ratio of the incoming flow rate to the passing flow rate through the through part of the combined dam is introduced.The calculated dependences for determining the relative deviation of the dynamic flow axis of the specific flow rate in the non-displaced part of the flow are proposed, and the throughput of the through part through the flow coefficient is estimated. Numerical calculations performed for the conditions of the Chirchik River showed satisfactory results.
