Two erosion control methods are compared for cost effectiveness in reducing sediment loading into the streams; targeted replacement of agricultural crops and placement of vegetative filter strips (VFS) along field drains. The first method implements

Elevated suspended sediment levels in surface water bodies result in increased turbidity for the water body. This paper develops relationships between soil types, concentrations, and soil combinations with corresponding turbidity levels. Development

Soil Erosion.
Public awareness of the problems associated with erosion, such as sedimentation and loss of capacity ofdrainageways or undesirable sediment deposits on roads and public and private property, has increased in recentyears. To address this, communities

Naturally occurring riparian filter strips are widely recommended as a technique for removing chemicals from flow prior to entering a stream. Data on their effectiveness is sparse as is information on the partitioning of chemicals trapped by various

The two-dimensional description of concentrated flow networks is important in erosion control research and erosion modeling. This study describes a process called image registration to develop concentrated flow networks from photographs of erosion pl

A semitheoretical evaluation of the sediment deposition equation used in the CREAMS and WEPP models is presented. The original deposition relationship was presented in the CREAMS and WEPP models without theoretical or conceptual justification. In thi

Rill spacing, a critical variable in erosion models, is treated as a deterministic and fixed variable while in reality rill spacing at any distance down slope is a stochastic variable. A model, named PRORIL, was developed to account for this stochast

A rill erosion model, PRORIL, simulates the stochastic variability of rill networks, including both variable rill spacing and rill flow rates, on erosion. PRORIL was compared to measured erosion using the Kentucky rainfall simulator at the University
