| Outline of Final Research Achievements |
As a new approach to evaluation of water quality benefits, this study attempted to construct an integrated model of water quality and a regional economy. In the model, a suit of hydraulic submodels that account for water flow, water quality, early diagenesis, and aquatic cultures in tidal flats are integrated with a computable general equilibrium model that accounts for consumption, production, and waste water treatment activities. The integrated model was then used to simulate the impacts of alternative water-quality regulations on water quality and economic activity. An innovative aspect of the study is that the integrated model can be used quantify the value of ecosystem services as the avoided loss in economic output --- for example, the economic value of an increased shallow-water area is the increase in the value of economic output due to the associated increase in allowable pollution loads that are made possible by the increased environmental capacity for nutrient absorption.
