Trickle Irrigation Design Parameters

Published: 
January 1, 1974
U.S. Agency for International Development
Trickle irrigation is a system for supplying filtered water and fertilizer directly on or into the soil. Spraying is eliminated and water is allowed to dissipate under low pressure in an exact predetermined pattern. The outlet device which emits the water into the soil is known as an "emitter...Read more

Numerical Model of Flow in a Stream - Aquifer System

Published: 
November 5, 1974
U.S. Agency for International DevelopmentColorado State University
A three-dimensional, finite difference model was developed for simulating steady and unsteady, saturated and unsaturated flow in a stream-aquifer system. The basis of the model is the finite difference form of Richard's equation for unsaturated and saturated subsurface flow. Effects of stream...Read more
