BACKGROUND
DNDC and its embedded crop models were used to model agricultural demand for irrigation water based on soil conditions, climate (daily min and max temp, daily precipitation, radiation), and general cropping systems. This modeling simulation has been performed at higher spatial (5x5km resolution) and temporal (daily) resolution than CALSIM. Three reference climate years (1983, 1996 and 1997) are being used to simulate the range in climate conditions from the early1950s though early 2000s. Model outputs include GHG emissions and crop water demand that accounts for crop use, ET losses, and infiltration/leaching below the rooting zone. Total irrigation use is estimated based on DNDC modeled irrigation demand to meet agronomic demand adjusted by an irrigation efficiency factor to account for over irrigation and efficiency of irrigation systems in California.The DNDC model flow is illustrated below:
