Abstract: An analytical solution for the thickness of the transition zone between fresh and seawater in aquifers on ocean islands is presented. The interface is treated as a mixing layer similar to a laminar boundary layer between ...

Abstract: The two‐dimensional nonlinear partial differential equation that describes the transient movement of water in an unsaturated porous medium is investigated by using the zero‐order continuous linear finite element method. ...

Abstract: Soil‐water distributions in homogeneous soil profiles of Yolo clay loam and Yolo sand irrigated from a circular source of water were measured at several times after initiation of irrigation. The effect of trickle discharge ...
