Runoff, infiltration and soil erodibility studies in the Otutira catchment
Yellow-brown pumice soils cover a large area of the central North Island of New Zealand. In the Waikato River basin these soils occupy over 7,000km². Since land development started in the mid-1930s approximately 4,000km² have been converted from the native vegetation to exotic forests (1,243km²) …

Variability of soil erodibility: its relationship to topography and soil properties in cultivated landscape
The hypothesis of this thesis is that soil erodibility varies systematically with landscape topography. This hypothesis was tested by using a portable rainfall simulator to measure the relative soil erodibility at five slope positions along eleven slope transects on fallow agricultural land in …

The determination of surface mine soil erodibility factors for two soils in southern West Virginia
… three replicated plots to determine surface mine soil erodibility factors for two distinctly different soils in southern West Virginia. Other variables included in the study were detailed soil descriptions for each site, initial and final soil moistures, plot rainfall distributions and the …

Evaluation of an In Situ Measurement Technique for Streambank Critical Shear Stress and Soil Erodibility
… streambank critical shear stress (Ï c) and soil erodibility (kd). Previous research showed streambank kd and Ï c can vary by up to four orders of magnitude at a single site; therefore, it is essential to determine if the large range is due to natural variability in soil properties or errors …

Changes in Streambank Erodibility and Critical Shear Stress Due to Surface Subaerial Processes
Previous studies have shown that soil erodibility and critical shear stress are highly influenced by weathering processes such as freeze-thaw cycling and wet-dry cycling. Despite over forty years of research attributing changes in soil properties over time to climate-dependent variables, little …

Evaluation of the Jet Test Method for determining the erosional properties of Cohesive Soils; A Numerical Approach
… require field measurements to determine the soil erodibility since soil characteristics are highly variable between sites, especially for cohesive soils. The submerged jet test device is an in situ method of determining the critical shear stress and soil erodibility of cohesive soils. A …

The Effects of Vegetation on Stream Bank Erosion
… This goal was addressed by measuring the erodibility and critical shear stress of rooted bank soils in situ using a submerged jet test device. Additionally, several soil, vegetation, and stream chemistry factors that could potentially impact the fluvial entrainment of soils were measured. …

Characterization of Watersheds on Fort Benning Military Reservation: Comparison of Field Data to Watershed Parameters
… to physical data. Land use, slope, and soil data were used in a modified revised universal soil loss equation (RUSLE) to create a soil erodibility index map. Wolman Pebble Count data showed that in half of the watersheds, 84% of the sampled grains were less than half a millimeter in …

Do Roots Bind Soil? Comparing the Physical and Biological Role of Plant Roots in Streambank Fluvial Erosion
… boundary layer could influence streambank soil erodibility. Specifically, the goal of this research was to quantify the physical and biological effects of roots on streambank fluvial erosion. A series of laboratory-scale erosion tests were conducted using a mini jet erosion testing device …

Analysis of soil erodability and rainfall erosivity on the Soutpansberg Range, Limpopo Province, South Africa
Soil erosion is a global challenge that threatens ecological functionality. The need for better soil conservation practices keeps growing due to the twin challenges of climate change and population growth. However, effective soil erosion management solutions remain elusive to practitioners due to …

Preconditional factors affecting the adoption of conservation tillage practices for Elgin, Middlesex and Oxford counties (Ontario).
… tillage. Slope length and gradient and soil erodibility were found to be poor predictors of adoption. Also, adoption rates did not significantly differ between cashcrop and non-cashcrop operations. Five variables were found to offer significant explanation of adoption of conservation …

Assessment of soil erosion hazard around the abandoned mine in formerly Mutale Municipality, Limpopo Province, South Africa
… and pollution monitoring was the result. Soil erosion has been recognised as an environmental hazard that emanates from abandoned mines. This study seeks to assess the soil erosion hazard around Nyala abandoned mine. The modified method of Soil Loss Estimation Model for Southern Africa …

Optimizing the management of soil erosion using GIS
… for designing dams, reservoirs, channels, soil conservation management plans, and the evaluation of on-site and off-site damages by soil erosion, land use projects, and transport of pollutants. This thesis presents the Modified Universal Soil Loss Equation (MUSLE) as a promising tool for …

Predicting Soil Erosion on Off-Road Vehicle Trails in Southwest Missouri
… on specially designated trails since the 1960s. Soil erosion is a focal area of concern for environmental groups in the area. Methods for predicting soil erosion include the Universal Soil Loss Equation (USLE), Modified Universal Soil Loss Equation (MUSLE) and Geographic Information System (GIS) …
