Reclamation Information Sharing Environment (RISE)

The Bio-Physical Crop Land Atmosphere Water Simulator (BPCLAWS) model was developed to address research needs identified by Reclamation, U.S. Army Corp of Engineers and other Federal and Non-Federal Partners. Specifically, the need to better understand how climate and CO2 changes impact plant physiology and how impacts vary by crop type and affect irrigation demand and crop yield were identified as a high priority research needs. To address these research needs, the BPCLAWS project developed a crop model combining physiologically based plant growth and transpiration processes with physical processes affecting water and nitrogen content in the soil.
