The development of a process model for determining groundwater accessions

Abstract

The derivation of a computer based process model designed to predict recharge to groundwater using daily data on rainfall and potential evapotranspiration is described. Methods of deriving daily potential evapotranspiration from commonly read meteorological data are given. An account of the hydro geology of the Sherwood Borefield and the development of a computer based model used to successfully model the Sherwood Borefield groundwater system is presented to provide a background for evaluation of the recharge process model developed. A sensitivity study of the daily time step process model is presented. The daily model is shown to successfully model recharges previously established for the Sherwood Borefield
