Abstract: Subsurface drains in clay soil overlying a shallow artesian aquifer intercept water from the aquifer and the deep percolation from the root zone. Flow down the backfilled drain‐line trench is significant immediately after ...

Abstract: The performance of subsurface drains in a clay soil overlying an artesian aquifer is evaluated at a site in Imperial Valley, California. Field studies are undertaken to examine water and salt movement through the soil ...

Abstract: This paper assesses the potential of the “reduced-runoff” surface irrigation method for clay soils to limit tailwater runoff and evaluate its impacts on crop production and soil salinity throughout a 3-year alfalfa hay ...
