Surface runoff and sediment yield in the Ardèche rangelands

Earth Surface Processes and Landforms, 1984
AbstractThis paper presents a case study of runoff and sediment generation under Submediterranean rangeland conditions (Ardèche drainage basin, France). Measurements indicate that on a rough hillslope interrill runoff and sediment are not produced uniformly over the slope surface.

Simulation of Runoff and Sediment Yield using Artificial Neural Networks

Biosystems Engineering, 2006
Daily, weekly, ten-daily, and monthly monsoon runoff and sediment yield from an Indian catchment were simulated using back propagation artificial neural network (BPANN) technique, and the results compared with the observed and with those due to single- and multi-input linear transfer function models.

[Effects of shrub patch pattern on runoff and sediment yield].

Ying yong sheng tai xue bao = The journal of applied ecology, 2020
Understanding the changes of runoff, sediment transport, and hydrodynamic parameters of slopes under the influence of landscape patch coverage and connectivity is of great significance for revealing the hydrodynamic mechanism and hydrological connectivity of slope soil erosion process.

Toxaphene and Sediment Yields in Runoff from a Mississippi Delta Watershed

Journal of Environmental Quality, 1981
AbstractToxaphene (chlorinated camphene) and sediment concentrations in runoff from a 15.6‐ha watershed, planted to continuous cotton (Gossypium hirsutum L.), were measured from 1973 through 1975 to determine the toxaphene and sediment yields and to define the major mode of toxaphene transport.

Tillage system effects on runoff and sediment yield in hillslope agriculture

Field Crops Research, 2001
Abstract Runoff and soil erosion are major factors of land and lake degradation in the Patzcuaro Watershed located in Michoacan, Mexico. This non-point source pollution results from corn cultivation on steep cropland sites. In the local farming system, the soil is bare for much of the year and subject to frequent plowing and cultivation. Conservation

Weather types, runoff and sediment yield in a Mediterranean mountain landscape

Earth Surface Processes and Landforms, 2013
ABSTRACTThe relationship between the synoptic weather types (WTs), runoff and sediments in a Mediterranean mountain landscape was analysed. The study was performed between 2005 and 2012 using one of the most complete and extensive daily databases of rainfall, runoff and sediment recorded in the Spanish Pyrenees, coupled with WTs defined from the ...

EFFECT OF WATERSHED SUBDIVISION ON SIMULATION RUNOFF AND FINE SEDIMENT YIELD

Transactions of the ASAE, 1997
The objective of this study was to establish the subwatershed size dependency of the Soil and Water Analysis Tool (SWAT) erosion model to adequately simulate annual runoff and fine sediment (< 0.063 mm) from the 21.3 km2 Goodwin Creek Watershed (GCW).

A Process-Based Method for Evaluating Terrace Runoff and Sediment Yield

2012 Dallas, Texas, July 29 - August 1, 2012, 2012
Terraces have been proven to be an effective conservation practice for controlling high soil loss. In large hydrological programs such as Soil and Water Assessment Tool (SWAT), terrace effects are simulated by adjusting the slope length and the USLE P-factor.

Effects of Herbaceous Plants on Hydrodynamic Characters of Runoff Water, and Runoff-Yielding and Sediment-Yielding Processes on Loessial Earth-Road Surface

Advanced Materials Research, 2012
Runoff and soil losses from earthen hillside roads are a serious problem on the Loess Plateau in China. Indoor rainfall simulation was employed to investigate hydrodynamic characteristics of runoff water, and runoff-yielding and sediment-yielding processes on earth-road surfaces with different coverage degrees of herbaceous plants.

Effects of multiyear precipitation variations on watershed runoff and sediment yield

Journal of Soil and Water Conservation, 2008
A study was conducted on the Fort Cobb reservoir watershed (787 km2 [304 mi2]) in central Oklahoma to investigate impacts of persistent multiyear precipitation variations on watershed runoff and sediment yield. Precipitation variations lasting five or more years with predominantly above or below average annual precipitation are commonly found in long ...
