A computer-simulation model for open feedlot runoff-control systems was used to develop a data base of important climatic variables that can affect the per-formance of systems. Moisture deficit was found to be most important for irrigation-disposal systems; the ratio of precipitation to evaporation, for evaporation systems. A method to size components of feedlot runoff-control systems for any specific location is presented, along with necessary coefficients for the method. Variables included are location, soils, crops, disposal area, disposal rate, retention pond depth, disposal management, and per-cent of runoff controlled. |
