An analytical method for computing return flow or drainage from irrigation applications is presented and discussed. Computations consider aquifer properties, drain spacing, and deep percolation. A graph for determining the fractional part of percolation remaining in transient storage is included. By using the graph and simple digital procedures, realistic estimates of irrigation return flow can be determined. The method was used to determine monthly quantities for 13 yr of return flows in the Mesilla Valley, New Mexico-Texas. This study is reported.
