1) Apply SWAT to the island of Maui, focusing detail on the watersheds that supply water to the existing canal system, using readily available soils, precipitation, sugar cane management, and yield data. 2) Assemble all existing rainfall and temperature data for the island of Maui and use the PRISM model to create a high resolution grid of precipitation and temperature. PRISM accounts for elevation, aspect, and slope when creating the interpolated grid. 3) Verify environmental impacts of optimal-yield sugarcane management practices via on-the-ground monitoring. Use existing USGS stream flow gages and water quality data collected in this study to calibrate and validate SWAT. 4) With the calibrated model, simulate alternative agronomic management of additional fields, including changing feedstocks, and nutrient and water management. Determine water supply and water quality impacts of the various alternatives.
