Abstract: A laboratory investigation was conducted to measure wetted radii and drop sizes and to estimate the energy characteristics of a rotating spray-plate sprinkler. Maximum wetted radii were positively related to increasing ...

Abstract: Previous simulation studies dealing with surface runoff use mathematical models based on a single soil infiltration relationship to estimate the influence of irrigation application depths and rates on surface runoff depths. ...

Abstract: The 340,000 ha Lake Dakota Plain area in north-central South Dakota has the topographical and soil characteristics required for the use of combination subsurface drainage and irrigation systems. Corn yield data from a ...
