Scaled space and time variables in soil-water and groundwater flux-boundary problems

Zusammenfassung:Scaled space and time variables for use in soil-water and groundwater problems are given for flux-boundary conditions that are proportional to the time raised to some power, of which the constant flux-boundary condition is a particular case. In the general case of time-dependent surface fluxes, the scaling of variables is possible in certain circumstances. These scaled variables may be used in one-dimensional problems of soil-water absorption and of groundwater recharge, and also in radial problems, for example those of water movement to plant roots and of water abstraction by wells.
