Optimization of Water Quality and Conservation Investments in the Lower Suwannee and Santa Fe River Basin

Minimum flows and levels (MFLs) and Total Maximum Daily Loads (TMDLs) for nitrate have been proposed for both the Lower Suwannee and Santa Fe Rivers. To meet the TMDL it is estimated that a 58% and 35% reduction in nitrate loads will be required in the Lower Suwannee and Santa Fe Rivers, respectively. To meet the MFLs, current "recovery" goals range from 1,000 to 3,800 mgd per acre of irrigated agriculture.

The overarching objective of this research is to examine the economic value of water in agricultural and in-stream (recreational) uses by examining the feasibility of a market-based payment program for ecosystem service provision. This project will determine the viability of creating a market for water conservation and water quality improvements to achieve the TMDLs and MFLs. To achieve this overarching objective, the specific objectives fall into five main component areas:

1) Determine the costs of agricultural water conservation and pollution reduction strategies,
2) Determine the value of water quantity and quality for in-stream use,
3) Hydrologic/water quality modeling,
4) formal on-campus teaching, and
5) public educational outreach/extension.

My research group is focused primarily on 3) Hydrologic/water quality modeling. This modeling will be conducted to estimate the changes in agricultural production practices and investments by producers that will be required to achieve the TMDLs and MFLs, and to determine how future water shortages may affect the region. Potential future water shortages will be estimated using the suite of Global Climate Model projections from the Coupled Model Intercomparison Project phase 5 (CMIP5).
