Web13 Nov 2009 · Aquifer Parameters • In order to assess groundwater potential in any area and to evaluate the impact of pumpage on groundwater regime, it is essential to know the aquifer parameters. These are Storage Coefficient (S) and Transmissivity (T). 3. Storage Coefficient (S) is the property of aquifer to store water in the soil/rock pores. WebThe Dupuit-Thiem equation is normally used to assess flow towards a pumping well in unconfined aquifers under steady-state conditions. For the formulation of the equation it is assumed that flow is laminar, radial and horizontal towards the well. It is well known that these assumptions are not met in the vicinity of the well; some authors restrict the …
