Lower Yampa Streamflow and Sediment Modeling

Water from the Yampa River basin continues to be sought for a number of municipal, industrial, and energy uses.  Water development in the Yampa River basin will alter the streamflow regime and, consequently, will lead to changes in the transport and storage of suspended and bedload sediment.  Changes in the Yampa River sediment budget could lead to changes in channel geometry, riparian...

Numerical simulation of groundwater flow in the Lost Creek Designated Groundwater Basin, Weld and Adams Counties, Colorado

The Lost Creek Designated Ground Water Basin (LCDGWB) is an important alluvial aquifer for water supply in northeastern Colorado. Increased demand for withdrawals from the LCDGWB has led to a concern about the long-term sustainability of the basin’s ground-water resources.

A numerical ground-water flow model developed using an early version of MODFLOW exists for the LCDGWB. A review and...
