Abstract: An array of ditches method of subsurface drainage is advantageous for various playgrounds, golf courses, parks, and also for orchard plantation where there is little farming operations. A comprehensive analytical solution ...

Abstract: A methodology for optimal spacing in an array of ditches fully penetrating into homogeneous and isotropic porous medium of finite depth over an impervious layer is presented. The cost function includes the depth-dependent ...

Abstract: A comprehensive analytical solution for the quantity of seepage into an array of fully penetrating ditches from a ponded surface has been obtained using hodograph and Schwarz–Christoffel transformation. The solution includes ...
