Regional Groundwater - Flow Model of the Redwall-Muav, Coconino, and Alluvial Basin Aquifer Systems of Northern and Central Arizona

摘要

The purpose of this report is to document the development of a groundwater-flow model that simulates the groundwater-flow system that existed in northern and central Arizona before development of groundwater supplies, pre-1938, and the flow system that occurred during development of the resource, 1938-2006. The groundwater-flow system of northern and central Arizona includes the basins of the Verde, Salt, and Little Colorado Rivers and adjacent areas of the western Coconino Plateau. Within the regional extent of the model there are several areas where management of groundwater resources are of interest. Use of the model for assisting management decisions is of particular interest for several areas. These areas include the Little Chino, Big Chino, and Verde Valleys, where groundwater discharge to the Verde River and potential capture of groundwater flow from adjacent areas including the Coconino Plateau and Little Colorado River Plateau basins is a primary interest. Included in the report are discussions of pertinent background information on the hydrology of the study area, modeling procedure, and results of steady-state and transient simulations.
