Effective discharge was estimated for two sites along Lehman Creek, an alpine fluvial system. Site one (WL-1, 2951 m elevation) has an effective discharge of 0.083 m3/s and site two (WL-2, 2019 m elevation) has an effective discharge of 0.400 m3/s. Calculated bankfull discharges are 2.52 m3/s for WL-1 and 1.48 m3/s for WL-2. Bankfull/effective discharge ratios (b/e ratio) are 30.49 for WL-1 and 3.71 for WL-2. The b/e ratio difference may be due to the steeper gradient (WL-1: 0.14, WL-2: 0.062) at WL-1, which may indicate active downcutting as a response to tectonic uplift in the Basin and Range province. WL-1 also sits on resistant glacial debris (quartzite), which may cause Lehman Creek difficulty in shaping and maintaining its stream channel.","abstract_html":"Effective discharge is defined as the streamflow that transports the most sediment over time and is therefore the flow that controls channel shape.
