Sediment Yield From Small Semiarid Watersheds
Small watershed sediment yield data were evaluated for eight small watersheds ranging from 35.2 to 159.5 ha within the United States Department of Agriculture – Agricultural Research Service Walnut Gulch Experimental Watershed (WGEW) in southeastern Arizona, USA. Stock pond sediment accumulation measurements covering time periods from 30 to 47 years were combined with water level records and es...
متن کاملMeasured Sediment Yield Rates From Semiarid Rangeland Watersheds
Data describing long-term sediment yield rates on semiarid rangeland watersheds are relatively rare. To augment existing data and gain a better understanding of the controlling variables, sediment yields from 8 subwatersheds within the US Department of Agriculture–Agricultural Research Service Walnut Gulch Experimental Watershed in southeastern Arizona were computed from stock pond sediment acc...
متن کاملUsing mixture analysis for soil information extraction from an AVIRIS scene at the Walnut Gulch
Spectral Mixture Analysis (SMA) has been used to extract qualitative and quantitative information about common features in an imagery at the subpixel level. At the Walnut Gulch Experimental Watershed (Arizona) this technique was used to produce the soil spectral map and quantify the fractions of each soil endmember on an AVIRIS image. SMA was applied on the base of image and reference endmember...
متن کاملSediment flow behaviour from small agricultural watersheds
Runoff, soil loss, sediment concentration, and particle size distribution of sediment eroded by runoff events were measured between 1976 and 2000 from 5 small agricultural watersheds on Vertisols at ICRISAT Center, Patancheru, India. The effects of storm size and land management system on total soil loss and size distribution of sediment during runoff are discussed. At the beginning of runoff e...
متن کاملMeasuring and Modeling Suspended Sediment Yields in Urbanizing Georgia Piedmont Watersheds
This paper presents a comparison of U.S. Geological Survey stream monitoring station measurements of total suspended solids (TSS) yield and stream bank erosion monitoring data with a suspended solids model developed by Brown and Caldwell and used by the Gwinnett County, Georgia Department of Water Resources (DWR) to inform its watershed improvement efforts. A comparison between modeled and aver...
