Patent ID: 8140309

Claim:
A processor-based method of predicting the dynamic behavior of water table in a two-dimensional anisotropic unconfined aquifer having a general time-varying recharge rate from multiple rectangular recharge basins, the said method comprising the steps of: a. obtaining data relating to the two-dimensional unconfined aquifer and data describing flow of ground water in the unconfined aquifer; b. obtaining data describing the conditions existing at the boundaries of the two-dimensional aquifer, location and dimensions of at least one rectangular recharge basin located within the aquifer; c. calculating rate of recharge (P) for at least one or more of the said recharge basins using the processor wherein the rate of recharge is calculated as a general time and/or space varying recharge function; d. describing the groundwater flow in the two-dimensional anisotropic unconfined aquifer, based on steps (a), (b) and (c), in the form of second order diffusion equations; and e. digitally implementing a solution to the above system of equations by using finite Fourier Transform method thereby predicting the dynamic behavior of water table in two-dimensional anisotropic unconfined aquifer, wherein visualization of the transformed data is output from the processor.
