Beginning of Motion for Selected Unanchored Residue Materials
Publisher: American Society of Civil Engineers
Abstract: Conservation tillage systems help to maintain residue materials from the previous crop on the soil surface. The potential for serious erosion may exist if crop residues are removed by overland flow. This study is conducted ...
Maximum Surface Storage Provided by Crop Residue
Publisher: American Society of Civil Engineers
Abstract: Small ponds created by crop residue serve to store water on upland areas. The present study is conducted to identify the maximum surface storage provided by crop residue. Equations for estimating surface storage are derived ...
Darcy‐Weisbach Roughness Coefficients for Gravel and Cobble Surfaces
Publisher: American Society of Civil Engineers
Abstract: A laboratory study is conducted to measure Darcy‐Weisbach roughness coefficients for selected gravel and cobble materials. Varying rates of flow are introduced into a flume in which a given size class of gravel or cobble ...
Closure to “Darcy‐Weisbach Roughness Coefficients for Gravel and Cobble Surface” by John E. Gilley, Eugene R. Kottwitz, and Gary A. Wieman (January/February, 1992, Vol., 118, No. 1)

Transport of Nutrients by Overland Flow on Sites Containing Beef Cattle Manure
Publisher: American Society of Civil Engineers
Abstract: In an inductive metastudy, we investigated the effects of varying rates of overland sheet flow on the transport of phosphorus (P) and nitrogen (N) from sites containing beef cattle manure. The analyzed data were collected ...
Legacy Nutrient Transport by Overland Sheet Flow
Publisher: American Society of Civil Engineers
Abstract: The transport of phosphorus (P) and nitrogen (N) from sites containing varying quantities of legacy nutrients was evaluated in this investigation. The data that were examined were collected during four previously reported ...
