A Physically Based Approach for Estimating Hydraulic Conductivity fromHPTPressure and Flowrate

GROUNDWATER, 59(2), 266–272.

By: R. Borden n, K. Cha & G. Liu

MeSH headings : Electric Conductivity; Groundwater; Water; Water Movements; Water Wells
TL;DR: Prior numerical modeling results are used to develop a relationship between probe advance rate V, probe diameter D, water injection rate Q, corrected pressure Pc, and hydraulic conductivity K and this equation provides a physically based approach for generating hydraulic Conductivity profiles with HPT tooling.
