AnsQuick: a set of online calculators for quick estimating of drawdown and other parameters that are useful for pumping tests planning

Drawdown calculator

'pumping tests planning caluclator

AnsQuick is indispensable for the pumping tests planning. The module contains a set of templates for standard hydrogeological conditions. The templates facilitate quick assessment of drawdown in an observation well during a pumping test. This allowsdetermination of the optimal discharge rate and the distance between the wells during pumping tests so that as to obtain the required drawdown for a specified time.

AnsQuick is a simplified versions of AnsTest and AmWells. It does not have the advanced graphical tools of AmWells or interpretation capabilities of AnsTest but it allows quick assesment of preliminary data. Module is designed for the Windows operating system.
