Hubbard Brook Experimental Forest (USDA Forest Service): Sediment Yield in Weir Basins

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. Oven-dry weights are then calculated for all of 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 as part of the Hubbard Brook Ecosystem Study (HBES). The HBES is a collaborative effort at the Hubbard Brook Experimental Forest, which is operated and maintained by the USDA Forest Service, Northern Research Station.
