Abstract: Kriging is a powerful tool for interpolation and network design. A necessary prerequisite for a kriging application is the variogram that describes the variation of the semivariance with distance. Variograms are routinely ...

Abstract: A linked kernel-optimization model for the planning of optimal groundwater development for irrigation is presented. The planning ensures optimization of zonal crop patterns subject to the constraints on the maximum water ...

Abstract: A numerical model of variably saturated axis-symmetric radial flow is employed to simulate and parameterize the gravity-delayed drainage, viewing it as the vertical accretion over falling water table. Numerical experiments ...

Abstract: Analytical solutions exist for the seepage discharge from polygonal and nonpolygonal canal sections underlain by a drainage layer at a hydraulically infinite depth. These solutions lead to underestimation of the seepage ...

Abstract: Analytical solutions exist for the problem of determination of seepage loss from polygonal sections such as a triangle, a rectangle, and a trapezoid. In this investigation, seepage from circular and exponential sections ...

Abstract: A numerical model of two‐dimensional transient saturated flow to ditches is presented. The model is based on a finite differences solution of the differential equation governing two‐dimensional transient flow in a heterogeneous ...

Abstract: Two‐dimensional transient flow to ditches or drains in a heterogeneous, anisotropic porous medium is modeled for appropriate initial and boundary conditions using the finite differences method for the entire saturated‐unsaturated ...
