Interpretive Summary: The USDA's EAH model is an event-based model that will be used to assess the various impacts of both the present and the proposed water management systems on hydrologic conditions, flood mitigation, agricultural production and water quality for farms within the C-111 basin. After the model's parameterization and evaluation, it will be used for selecting the Best Management Practices for the region, given either the present or proposed water management system (Everglades Restoration Plan). The EAH model will also be used to help conservation efforts by quantifying water quality improvements over time in areas with the potential to deliver the highest rates of nutrients and pesticides to the aquifer.

Technical Abstract: A computer model, the Everglades Agro-Hydrology Model (EAHM), has been developed to evaluate the impact of agricultural practices on the water quantity and quality of the region. The objective of this research note is to present the EAHM governing equations and present the interface of the model. The EAH model will simulate the following processes at a specific farm using a given rainfall event as an input: 1) Plant transpiration, soil evaporation, root zone soil moisture, and storm runoff, 2) crop yield under the current and alternative hydro-meteorological regime, 3) pesticide and nutrient movement within the root zone, 4) dissipation/degradation of pesticide residues and their subsequent fate in aquatic ecosystems, and 5) mitigation actions which might be taken to reduce exposure to pesticides.
