Some Numerical Experiments on the Variably-Saturated Flow Equationrguments are used to define the specific storativity (which is useful for saturated flow simulation). The Richards’ equation, under transient conditions, is highly nonlinear. Traditionally, numerical techniques have been used in solving this equation. The moisture-content form of Richards’ equation犬儒主义者 发表于 2025-3-29 14:56:39
Is It Correct to Assume That Movement of Water in Unsaturated Soil Strata is a Piston Flowa is homogeneous from surface to water table, it is simple to work with, but in nature this may not be possible. The soil strata may be built-up of different layers of different compositions, compaction and of different grain size which may complicate the situation.

A New Technique for the Calibration of Neutron-Moisture Probeamount of water (equivalent to some ponded height of water) is applied at the soil surface. The infiltrated water is accounted for by integrating the change in observed volumetric moisture content by neutron probe. This total infiltrated water should be equal to the water applied at the surface owin绝种 发表于 2025-3-29 19:50:55
Estimation of Canal Seepage in a Layered Porous Media Using Boundary Element Method and also in the efficient utilization of available water. Here, a mathematical model based on the boundary element method is presented to estimate the steady state seepage losses from an irrigation canal into the adjacent layered isotropic media. The results are compared with those obtained by usin
