An analysis of the automatic water level monitors data at different positions in a pumping test
Shuiwen dizhi gongcheng dizhi, 2022 In a pumping test, recording and analysis of the dynamic water level data are of great significance in the calculation of hydrogeological parameters. In recent years, automatic water level monitors have been widely used in pumping tests, and the pressure

Refinement indicators for estimating hydrogeologic parameters [PDF]
Inverse Problems in Science and Engineering, 2018 We identify simultaneously the hydraulic transmissivity and the storage coefficient in a ground water flow governed by a linear parabolic equation. Both coefficients are assumed to be functions which are piecewise constant in space and constant in time.
