Hydrologic Effects of Improved Agricultural Practices in the Galena Watershed

Abstract

In July of 2017, we joined graduate students from Missouri State University in sampling in-channel sediment deposits for subsequent trace-metal analysis (Figure 2,3,4). As part of that field work, we made a variety of channel geometry measurements (which numbered over 100), including measurements of bankfull width. A subsequent linear regression analysis of our channel-width data was completed by plotting channel width as a function of drainage area following the technique of Magilligan. The drainage area data for the regression analysis was obtained using ArcGIS.
