In order to assess whole-field sprinkler irrigation uniformity, an experiment was conducted to obtain water distribution profiles at 23 different pressures for each of five different sprinklers: Nelson R33, Nelson R33LP, Nelson R33 with road guard, Nelson R33LP with road guard, and Rainbird Mini Paw/LG-3. A mathematical model was developed to account for(More)
This paper presents the design and development of an open source map-based software package, PVMapper – Site Designer (PVMSD), for designing large scale photovoltaic (PV) systems. PVMSD uses numerous factors to reflect the characteristics of landscape specific to the area including site location, time zone, sun path, nearby weather station data, tilt and(More)
A model was developed to analyze the steady-state hydraulics of branching pipe networks as found in on-farm pressurized irrigation systems with multiple outlets at sprinklers or emitters. The model uses a new methodology to identify all flow paths based on a shortest-path algorithm. It also uses elevation and hydraulic parameters to determine which outlets(More)
