Summary

General Groundwater-Model Construction System Version 0.1 (Genmod0.1) Groundwater residence-time distributions (GRTD) are critical for assessing lag times between activities at the land surface and the emergence of related solutes in the baseflow of streams. However, GRTD can not be measured directly, they must be inferred from an analysis of data using models. Glacial aquifers present challenges to modeling approaches because they are spatially discontinuous and have highly variable properties. An innovative approach developed by the U.S. Geological Survey (USGS) uses machine learning techniques in conjunction with numerical models that results in a rapid and robust way of generating GRTD. The main idea is to simulate groundwater [...]

Purpose

Version 0.1 serves to provide links to the Genmod (gw-general-models) and GRTD (gw-res-time) repositories on the official USGS organization on Github and to provide supporting datasets used by Genmod and GRTD as part of supplemental material used to generate 30 general models from which water-particle residence time distributions were determined in the work of Starn and Belitz (2018).
