Resumen
The overall objective of the proposed research is to
identify and quantify landscape attributes and hydrologic conditions that can be used to assess hillslope seepage and
ephemeral gully erosion. We propose to use three different
methodologies to study ephemeral gully development, i.e., 1)
laboratory rainfall simulation to quantify seepage and
hydraulic shear effects on rill or gully initiation; ...

The overall objective of the proposed research is to
identify and quantify landscape attributes and hydrologic conditions that can be used to assess hillslope seepage and
ephemeral gully erosion. We propose to use three different
methodologies to study ephemeral gully development, i.e., 1)
laboratory rainfall simulation to quantify seepage and
hydraulic shear effects on rill or gully initiation; 2) digital
photogrammetry from low altitude aerial photography to
quantify ephemeral gully development; 3) topographic
threshold based ephemeral gully erosion model with
subsurface hydrology. [--]
