Title

Ground and Surface Water Response to Changing Irrigation Practices: A Bitterroot Valley Case Study

Document Type

Abstract

The Bitterroot River is prone to channel migration. What was the main stem of the river in the late 1960's is now a side channel that requires periodic dredging. Kirk applied the MODFLOW flow-modeling program to the valley floor area and will demonstrate how he used hyrdologic features and groundwater recharge from irrigation activities to test how changes to irrigation methods can affect groundwater levels, ditch flows, and streamflow.
