Abstract:

Studies were performed on a high elevation (2440 meters or 8000 feet) valley stream system and a high (1980 meters or 6500 feet) cold desert stream system in Wyoming, to analyze the surface water and groundwater interactions that occur within these two extremely different types of stream systems. A hydrologic water budget analysis, aided by the use of the USGS groundwater model MODFLOW, was performed to identify the interactions that resulted. The two study areas have both been instrumented for over four years. A comparison of the two stream systems, on a yearly basis, indicate that water movement and storage are from one to more than 10 orders of magnitude greater for the high elevation valley system.
