South Fork Experimental Watershed
The South Fork Watershed of the Iowa River is the United States site for the Joint Experiment for Crop Assessment and Monitoring (JECAM). The goal of JECAM is to develop international standards and a "global system of systems" for agricultural research by sharing data, methods, and results from different cropping systems throughout the world.

The South Fork Watershed is situated in a four-county area in Iowa which is dominated by a corn-soybean crop rotation. Ongoing scientific investigations include measuring the impact of conservation practices on water quality, modeling the watershed using the Soil Water Assessment Tool (SWAT), collecting calibration/validation data for large-scale surface soil moisture remote sensing products, and evaluating water/energy/CO2 land surface flux models.
The South Fork experimental watershed is participating in the IFloodS experiment which studies precipitation estimation using high resolution radar. This is a preparatory experiment for the Global Precipitation Measurement (GPM) mission. The network will also provide validation data for the Soil Moisture Active Passive (SMAP) mission which launches in 2014.
