Competition model in groundwater: Three boreholes taping water out from same aquifer

We introduced for the first time a competition model for groundwater. The model present the competition between three borehole taking water out from the same source with different discharge rates, while we assume that the transmissivity and the storativity of the geological formation are the same in time and space. The model is built for a confined aquifer. We presented the conditions under which the uniqueness of exact solutions is reached. We solve the model analytically and numerical under some circumstances and presented their numerical simulations. (C) 2019 Published by Elsevier Ltd.
