Hubbard Brook Experimental Forest (US 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.
