Volume 29, Issue 6 , January and February 2015, , Pages 1438-1446

https://doi.org/10.22067/jsw.v29i6.35122

Abstract
  Introduction: Labyrinth weirs compare with straight weirs had required less freeboard in upstream so they are more appropriate for the irrigation networks. So they could maked more space to sotrage water and restrained foold with higher discharge. Labyrinths weirs have three generally form triangles, ...  Read More

A. Shahnazari; A. Ziatabar Ahmadi; Mirkhaleg Ziatabar Ahmadi; Gh. Aghajani

Volume 27, Issue 2 , May and June 2013, , Pages 432-440

https://doi.org/10.22067/jsw.v0i0.24588

Abstract
  The downward flow to the drain pipe, has a greater influence on the movement of soil particles toward drain envelope as compared with the horizontaland radialflow. In this study, by installing of a singular subsurface drainage systemconsisting of threedrain pipeswith drain spacing of 20 m and drain depth ...  Read More
