Hubbard Brook Experimental Forest: Sediment Yield in Weir Basins, 1956 - ongoing

Each year the sediment that collects in the stilling basin behind the v-notch weir is measured, excavated, sampled, dried, and weighed for Watersheds 1 through 8 at the Hubbard Brook Experimental Forest. Oven-dry weights are then calculated for all the sediment removed from the basin and extrapolated back over the watershed as mass of soil material lost per unit area. These data were gathered at the Hubbard Brook Experimental Forest in Woodstock, NH, which is operated and maintained by the USDA Forest Service, Northern Research Station.
