Interpretive Summary:

Technical Abstract: While dynamic hydraulic modeling has traditionally focused on high-order rivers and downstream reaches, rangelands typically support low-order, relatively small streams and narrow riparian zones. The ability to reliably model streamflow, sediment transport, and channel and floodplain geometry changes in rangeland streams will enhance range managers' ability to quantitatively analyze streams and riparian zones. We demonstrate a dynamic hydraulic simulation model coupling observed streamflow, sediment load and storm hydrographs with physical channel and floodplain morphology for an upland rangeland stream, Reynolds Creek in southwestern Idaho. Applications directly support planning for riparian and floodplain utilization, and highlight the need to include upland, headwater streams and their contributing watersheds in assessing river systems, and to recognize dynamic channel hydraulic processes in developing integrated management strategies for rangelands, headwaters and downstream river systems.
