A numerical model for the prediction of long term well yield in an unconfined chalk aquifer

B. J. Connorton* & R. N. Reed*

The prediction of the long term yield from individual pumped wells is one of the main problems to arise from the Thames Ground Water Scheme. A numerical method for solving this problem, more versatile than conventional non-equilibrium pumping test analysis techniques, is described. The method is based on the discrete space/discrete time radial flow model, developed recently by Rushton et al. (1974). Factors modelled include the detailed spatial distribution of aquifer parameters, a variable pumping rate, natural recession and wellfield interference effects. An outline of the fundamental hydrogeological aspects of the modelling work is also given.
