An invitation to participate in a North American sediment-monitoring network



An informal collaboration has been established to encourage the development of a North American network for the collection, analysis, and interpretation of fluvial-sediment data. The principal objective of the network is to define continental-scale gradients of mean yield, variability of loads, particle-size distributions, and natural regimes for suspended and bed sediment released during unstressed to minimally stressed conditions of land use. Extending that goal, a second objective is to identify stream reaches where fluxes of sediment and associated contaminants now are elevated to levels at which water quality and ecological integrity are compromised.
