Long-term sediment storage and flux in a small, catastrophically aggraded mountain catchment
Society and sediment in the Mining Rivers of California and Australia
Floodplain and Terrace Legacy Sediment as a Widespread Record of Anthropogenic Geomorphic Change
Anthropogenic erosion and sedimentation are critical components of global change that involve life-sustaining natural resources of soil and water. Many geomorphic systems have responded to intense land use disturbance with episodic erosion and sedimentation, often orders of magnitude greater than background geological rates in the Holocene. Accelerated sedimentation is a metric for land use change and provides evidence of geomorphic change in fan…
Geomorphic Responses to Extreme Rainfall, Catastrophic Flooding, and Dam Failures across an Urban to Rural Landscape
The extreme rainfall of October 2015 in South Carolina generated numerous dam failures and spawned the flood of record at most U.S. Geological Survey stream gauges. Detailed field sampling and systematic image analysis are used to document the immediate and sustained geomorphic adjustments at four failed dams within the urbanized Gills Creek watershed. That urban focus is augmented with a similar analysis at five failed dams in more rural setting…
Impacts of urbanization on stormflow magnitudes in small catchments in the Sandhills of South Carolina, USA
Surface Water
Fresh surface water is a physical and socioeconomic phenomenon that can best be understood from an integrated or geographic perspective. The global water system delivers and stores water in key renewable reservoirs with strong spatial patterns. Surface water behavior at the soil–atmosphere interface is highly sensitive to human alteration, and urbanization greatly exacerbates flooding. Simple comparisons of water use between agricultural, industr…
Legacy sediment
Secular Sediment Waves, Channel Bed Waves, and Legacy Sediment
The concept of sediment waves is reviewed and clarifications are proposed for nomenclature concerning vertical channel responses to large fluvial sediment fluxes over a period of a decade or longer. Gilbert's (1917) original sediment waves are re-evaluated at their type locale and used to develop a consistent set of definitions. A 'sediment wave' represents a transient sediment flux that includes but is not necessarily identical to a 'channel bed…
Late Pleistocene Glaciations in the Northwestern Sierra Nevada, California
Pleistocene fluvial landforms and riparian ecosystems in central California responded to climate changes in the Sierra Nevada, yet the glacial history of the western Sierra remains largely unknown. Three glacial stages in the northwestern Sierra Nevada are documented by field mapping and cosmogenic radionuclide surface-exposure (CRSE) ages. Two CRSE ages of erratic boulders on an isolated till above Bear Valley provide a limiting minimum age of 7…
Sustained Storage and Transport of Hydraulic Gold Mining Sediment in the Bear River, California
Large deposits of hydraulic gold mining sediment remain in main channels of the Bear River more than 100 years after the cessation of mining. This study examines these deposits and reevaluates Gilbert's (1917) classic model of sediment transport in a symmetrical wave that is based on hydraulic mining sediment primarily in the Yuba Basin. Sustained storage and transport of hydraulic mining sediment in the Bear Basin are documented and a revised mo…
