Abstract

Abstract - Improvements upon the Birkbeck bedload sampler (Reid et al., 1980) were implemented in the North Fork of Caspar Creek, a gravel-bedded stream draining 383 ha in northern coastal California. Bedload sediment falls through a slotted plate covering a .125-m3 steel box set within a formed concrete pit in the streambed. In the original Birkbeck design, a water-filled pressure pillow beneath the box responded to the weight of accumulating sediment and the overlying water column.
