Two sub-models, a water balance model and a crop development model, interact to provide 5-day estimates of soil water content, evaporation and transpiration, runoff, and increments to biomass and grain yield. The water balance model takes inputs of daily rainfall and estimated potential evapotranspiration; biomass production is driven by actual transpiration and transpiration efficiency, and so is dependent on the timing and amount of water and energy utilization, partitioned between transpiration and evaporation according to leaf area index. The model is successfully tested against data from a range of climates.
