Abstract

Drainage are major part irrigation that Drainage design and construction with high efficiency, and perevevt of Saturation land essintion is information perfect  of  how  mechanism flow into the of the drainage pipes.this study using physical models CFD and computer FLUENTto give  behavior of the underground drainage pipe to get the distribution velocity and  profiles surface water in  drainage pipes and  hydraulic Gradient for 0.5 m long section of the floor below  drainage pipes, this purpose desing  hydraulic drainage simulations For a physical model of the drainage water in the Laboratory Engineering of water Tabriz University was built then flow drainage pipe simulations by the model CFD and whit drawn the lines flow  by FLUENT poits that losses have been identified. also The lines flow in the drainage pipe outlet and intel were simulated. The results obtained by simulation match very well with the experimental results. In result  CFD model that can be very useful tools for understanding the flow of underground drainage and to help design it.
