Time-depe ndencies of suspended-sediment discharge from six coastal watersheds of northern Califor nia
– Smith River, Klamath River, Trinity River, Redwood Creek, Mad River, and Eel River –were evaluated
using monitoring data from 1955 to 2010. Suspended-sediment concentrations revealed ti me-dependent
hysteresis and multi-year trends. The multi-year trends had two...
Variation in fluvial suspended sediment–discharge behavior is generally thought to be the product of changes in
processes governing the delivery of sediment and water to the channel. The objective of this study was to infer
sediment supply dynamics from the response of suspended sediment behavior to antecedent hydrologic factors.

The occurrence of two wildfires separated by 31 yr in the chaparral-dominated Arroyo Seco watershed (293 km²) of California provides a unique opportunity to evaluate the effects of wildfire on suspended-sediment yield. Here, we compile discharge and suspended-sediment sampling data from before and after the fires and show that the...
This study is an investigation into the roles of wildfire and changing agricultural practices in controlling the inter-decadal scale trends of suspended sediment production from semi-arid mountainous rivers. In the test case, a decreasing trend in suspended sediment concentrations was found in the lower Salinas River, California between 1967 and...
Rivers display temporal dependence in suspended sediment–water discharge relationships. Although most work has focused on multi-decadal trends, river sediment behavior often displays sub-decadal scale fluctuations that have received little attention. The objectives of this study were to identify inter-annual to decadal scale fluctuations in the suspended sediment–discharge relationship of a...
The magnitude, seasonality, and duration of peak discharge responses to forest removal and regrowth and roads in 10 pairs of experimental basins in the western Cascade Range of Oregon are consistent with fundamental water balance and routing concepts in hydrology. Hypothesized effects of forestry treatments on evapotranspiration, cloud water interception,...
