Modeling Streambank Erosion on Composite Streambanks on a Watershed Scale

Modeling watershed erosion with CASC2D

CASC2D is a physically-based, distributed model that simulates the response of a watershed to precipitation. Basic processes in the model include: precipitation, interception, infiltration, surface runoff and channel flow, and erosion and deposition of upland soil and channel bed sediment. Model performance is demonstrated by applications to numerous sites such as Goodwin Creek, MS. This waters...

Effects of Wet Meadow Riparian Vegetation on Streambank Erosion. 1. Remote Sensing Measurements of Streambank Migration and Erodibility

We quantified how rates of stream channel migration in a montane meadow vary as a function of the riparian vegetation community. The South Fork of the Kern River at Monache Meadow, located in California’s southern Sierra Nevada range, supports two distinct types of vegetation: a dry meadow community dominated by sagebrush and non-native grasses (xeric scrub and meadow), and a wet meadow communi...

Phosphorus Characterization and Contribution from Eroding Streambank Soils of Vermont's Lake Champlain Basin.

Streambank erosion is an important contributor to sediment and nutrient export. This study determined total P (TP), soil-test P (Modified Morgan's, MM-P), and the degree of P saturation (DPS) in eroding riparian soils along four Lake Champlain Basin stream corridors. We investigated the relationship between these data and soil texture and with a series of GIS-derived landscape metrics. We also ...

Hydraulic Erosion Modeling on a Triangular Mesh

Although hydraulic erosion modeling on a GIS terrain models has been addressed by a body of previous work, it still remains an open problem. In GIS, raster representation and triangular irregular networks (TIN) are the most commonly used surface models, because they are simple and offer implicit topological information. However, these data structures do not allow the simulation of erosion on co...
