  • Sediment storage and yield in an urbanized karst watershed
  • Cave ; Doline ; Karst ; Sediment budget ; Sediment transport ; Tennessee ; United States of America ; Urban area ; Watershed
  • This paper presents a preliminary assessment of fluvial sediment storage and yield in an urbanized, karst watershed. The AA. aim to identify and quantify the function of caves and sinkholes within the context of a sediment budget with 3 specific
  • the relative contribution of a major cave system to a preliminary sediment budget for a karst watershed.

  • Patterns of soil erosion and redeposition on Lucky Hills Watershed, Walnut Gulch Experimental Watershed, Arizona
  • Arizona ; Erosion rate ; Experimental catchment ; Isotope analysis ; Plant canopy ; Semi-arid area ; Soil erosion ; Spatial distribution ; United States of America ; Watershed
  • This study used radioactive fallout Cesium 137 to determine patterns of soil erosion and patterns and soil redistribution on Lucky Hill Watershed, a semiarid watershed, near Tombstone, Arizona. Soil redistribution was not significantly related

  • Spatial modeling of soil erosion potential in a tropical watershed of the Colombian Andes
  • Andes ; Coffee ; Colombia ; Erodibility ; Land use ; Model ; Pastureland ; Rill wash ; Scenario ; Soil erosion ; Tropical zone ; Watershed
  • Soil erosion potential of a watershed in the coffee growing region of the Colombian Andes was assessed using the Revised Universal Soil Loss Equation (RUSLE) in a GIS environment. The RUSLE factors were developed from local rainfall, topographic

  • Conceptual model of sediment processes in the upper Yuba River watershed, Sierra Nevada, CA
  • California ; Conceptual model ; Erosion rate ; Geographical information system ; Mass movement ; Slope dynamics ; United States of America ; Watershed
  • The conceptual model illustrates key processes controlling sediment dynamics in the upper Yuba River watershed and was tested and revised using field measurements, aerial photography, and low elevation videography. Finally, the AA. propose
  • at a watershed scale.

  • Erodibility ; Forecast ; Gully erosion ; Impact ; Mathematical model ; Soil erosion ; Topography ; Watershed
  • In this paper, 2 topographic indices, closely related to mathematical expressions suggested by different AA. are used to characterize the influence of watershed topography on gully erosion. The AS1 index is defined as the product of watershed area

  • Aquatic ecosystem ; California ; Dam ; Environmental management ; Fish breeding ; Gold ; Mining activity ; Sierra Nevada ; United States of America ; Water quality ; Watershed
  • First, historical geomorphic changes in the watershed are outlined that influence the physical context of the feasibility study. The Yuba watershed is centered in the hydraulic gold-mining region. Second, recent findings of high concentrations
  • of mercury in sediment and fish tissues in the watershed are briefly reviewed. Third, historic data on 20th century hydraulic mining are presented that document numerous small dams built in the Yuba basin to detain mining sediment. Finally, field measurements

  • Discharge and sedimentation periodicities in small sized watersheds
  • Discharge ; Experimental catchment ; Periodicity ; Runoff ; Sediment transport ; Sedimentation ; Semi-arid area ; Texas ; Turbulence ; United States of America ; Watershed
  • The AA. used wavelets to analyze the measured discharge and sedimentation during 2001 from the nested Agricultural Research Service watershed in Riesel, Texas. Periodicities from wavelet spectra were interpreted in terms of experiments conducted

  • dominance from-800-1300 A.D., paralleling paleorecords southward along the Atlantic seabord. Higher inputs of inorganic sediment during this interval suggest increased watershed erosion during drought conditions. European impact is manifested by a decline
  • in arboreal pollendue to land clearance, increased weedy plant cover, and an increase in inorganic particles to the watershed.

  • Geomorphology ; Gully erosion ; Hungary ; Morphometry ; Soil erosion ; Watershed
  • This paper presents a detailed analysis on the forms and processes of gully erosion in a hilly watershed (part of the southern catchment of Lake Balaton), based on morphometrical field measurement. A further aim was to characterise the development
