TR-48 : Type curves for multiaquifer well

Abstract

Type curves pertaining to aquifer test conducted in multi aquifer well, which is open to two aquifers, have been presented. Using these type curves the storage coefficient and transmissivity of each aquifer can be predicted. In a two aquifer system an observation well may tap a single aquifer or it may be open to both the aquifers. Some times the multi aquifer pumping well may also be used as an observation well. The type curves presented in the report include all these three cases. Use of the type curves for parameter estimation has been demonstrated using synthetic drawdown data.
