Abstract
The present invention relates to development of a method of predicting the dynamic behavior of water table in an anisotropic unconfined aquifer having a general time-varying recharge rate from multiple rectangular recharge basins. Each basin can have a different dimension and nature of rate of recharge. Aquifer can have prescribed head, zero flux, or a combination of both types of boundary conditions.

A method of predicting the dynamic behavior of water table in an 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 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 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 wherein the rate of recharge is calculated as a general time and/or space varying recharge function;
- d. describing the groundwater flow in the anisotropic unconfined aquifer, based on steps (a), (b) and (c), in the form of second order diffusion equations;
- and
- e. solving the above system of equations by using finite Fourier Transform method thereby predicting the dynamic behavior of water table in an anisotropic unconfined aquifer.
