Modeling of piping erosion in loess soils
Extended abstract Introduction Piping erosion is one of the common water erosions usually occurs in soil with low infiltration and soluble minerals that finally changes landscape. Different factors control its occurrence and development. To predict piping occurrence/hazard through modeling, effective factors should be prioritized and considered as inputs of the model. The present study...
متن کاملUpland Erosion Modeling
Significant advances in upland erosion modeling have been achieved in the past decade. The TREX (Two-dimensional Runoff, Erosion, and Export) watershed model has been developed at Colorado State University for the simulation of surface runoff from spatially and temporally distributed rainstorms on watersheds. The model has been applied in several countries with different climatic conditions. TR...
متن کاملShoreline Modeling and Erosion Prediction
This paper presents a shoreline-erosion prediction model of Lake Erie that can forecast shoreline changes from annual to 10-year increments. It was developed by using historical bluffline data of years 1973, 1990, 1994, and 2000 at Lake Erie provided by NOAA and local government agencies. The relationships among these historical shorelines are analyzed using a least-squares method. Erosion rate...
متن کاملModeling 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...
متن کاملValidation of Erosion Modeling: Physical and Numerical
The overall intent of this research is to develop numerical models of erosion of levees, dams and embankments, validated by physical models. The physical models are performed at 1-g and at high g’s using a geotechnical centrifuge. The erosion is modeled in detail, from beginning to end, that is from the time the levee is overtopped until the levee is breached. Typical quantities measured as a f...
