Channel Slope

The aim of the work is to analyze the existing method of calculating the spillway from the depth of the free flow under uneven mode in prismatic channels with a slowly changing movement and to develop a method of calculations that allows applying it to any flows in a prismatic channel without using any special tables. The existing methods for calculating flow parameters are based on the use of the Chesy formula to determine the flow consumption with a slowly changing water movement. At the same time, there is a V.I. Charnomsky’s method of direct calculation of the flow parameters from the energy equation without limiting the value of the channel slope. The disadvantage of this method is a possibility to solve the energy equation by the method of sequential approximation since the flow energy equation includes two variables, the flow depth and the distance between the sections. To eliminate this difficulty, it is proposed to determine the distance between the depths that make up the geometric progression on the considered part of the channel which allows calculating parameters of the free fl ow surface for any channel slopes and hydraulic flow modes without to special tables.

Integral Energy

The specific resistance and three other secondary coefficients in the instantaneous integral energy equation describing the flow in the Øresund strait, are accurately estimated from over two years of high resolution measurements. Parameter variation due to stratification, effectively insulating the flow from the effect of bottom friction, is demonstrated and quantified. Also, parameter variation with the flow direction is quantified. Residual error dynamics is discussed and described. The relevance of an additional linear resistance term in the flow energy equation is discussed.
