Deschutes Basin Ground-Water Study

An analysis of the major ion and isotope chemistry of ground water in the basin is provided in the report Chemical study of regional ground-water flow and ground-water/surface-water interaction in the upper
The geologic factors controlling the occurrence and movement of ground water in the basin are described in the report Geologic Framework of the Regional Ground-Water Flow System in the Upper Deschutes Basin. This report describes the geologic history and stratigraphy of the basin, and the resulting regional permeability distribution. It provides the geologic context for the discussion of ground-water flow in other reports.
The regional ground-water hydrology is described in Ground-Water Hydrology of the Upper Deschutes Basin, Oregon. This report describes the quantitative understanding of the regional ground-water flow system including the rate and distribution of recharge, flow directions (head distribution), ground-water/surface-water interaction, discharge, and the response to stresses.
The hydrologic understanding of the basin is synthesized and a numerical flow model is described in the report Simulation of Regional Ground-Water Flow in the Upper Deschutes Basin, Oregon. The report describes numerical model construction, steady-state and transient calibration, and example simulations of pumping and canal-lining scenarios.
Hydrologic, geochemical, and isotope data are combined to develop a conceptual model that is used to explain the influence of ground water on the surface-water hydrology in the following contribution to a larger monograph on the hydrology of the Deschutes River.
