We examined two of several cobble and boulder fields as part of an effort to interpret whether the overwash
Effects of Sediment on the Aquatic Environment: NRCS
Streambed particle distributions range from boulder dominated to clay dominated. Boulderbed streams are controlled by the watershed geology and are generally not selfformed. They are mountainous streams with high gradients and a cascade and steppool profile. The streambed is stable during most flows and becomes mobile only at very high flows.
