Abstract

An arid watershed at the Walnut Gulch Experimental Watershed (WGEW) near Tombstone, AZ, was instrumented with both systems and hydrologic and sediment data were collected and compared during a 2 year period. Total sediment yield for the entire period measured by the CSIRO pump sampler (developed by the Australian Commonwealth Scientific and Industrial Research Organization) was similar to that by traversing slot sampler. The pump sampler accurately estimated the amount of fine (< 0.5 mm) sediment fractions exported, but consistently underestimated the coarse (> 0.5 mm) sediment fractions. This study outlines the benefits and limitations of the pump sampler based system for monitoring sediment concentration and yield in high-energy headwater catchments, and makes recommendations for improvement of its performance
