Abstract

In order to attain the rate leakage losses of earthen channels without spending aenormous costs, can be used the software available in this field. Softwere mseep is used in this work software, including programs that analysis, the rate and how to move and water leak into the soil, at two-dimensional mood. Work based software is, finite element method for solving Laplace differential equation, which represents move stagnation, running water, is. In this software were analyzed total 18th earthen channel model with changes in height and the sides of the channel and internal side slope Z = 1 and Z = 0.5, And after extraction, final leak of the transverse sections of channels was observed, in similar circumstances, with a discharge equal with the increased height and sides of channel, (D and H), leakage losses becomes less. Also, observed was that, by reducing the amount of z, namely, increased internal side slope of the channel leakage losses are increasing.
