Sustainable water management in Iraq (Kurdistan) as a challenge for governmental responsibility [PDF]
, 2018 During the last few decades, a critical scarcity of water has occurred in the Middle East due to climate change and the mismanagement of water resources. The situation is complicated by the absence of an effective legislative framework at the local level

Sprinkler irrigation raises yields— and costs—of Imperial Valley alfalfa
California Agriculture, 1980 Alfalfa growers in the Imperial Valley have a choice between using sideroll-sprinkler and border-flood irrigation. Tests to determine which is the most feasible showed that border-flood irrigation is cheaper, but yields are higher when sprinklers are ...

Runoff Discharge from Border and Furrow Irrigation
Journal of Engineering and Sustainable Development, 2007 In this research, two procedures have been developed to predict runoff hydrographs from graded border and furrow irrigation systems. One of the procedures is based upon volume balance principle and the other is based upon the application of Manning's ...

Reuse System Design for Border Irrigation [PDF]
Journal of Irrigation and Drainage Engineering, 1985 A procedure is presented for designing a system to reuse runoff from free outflow irrigation borders. Runoff volumes are obtained using four dimensionless variables and runoff curves developed with a zero‐inertia mathematical model. An example of the design procedure includes different modes of reuse system operation.
