Integrating Stakeholder Values with Multiple Attributes to Quantify Watershed Performance
An important part of watershed assessment and planning is integrating stakeholder values into the process of quantifying impairment of ecosystem functions. This study explores a systematic evaluation of human and ecosystem indicators within a watershed to classify and prioritize degradation at a subbasin scale within the watershed. From this study, we developed the Watershed Performance Measure (WPM) which has three major components: hydrologic process, biodiversity at a species scale, and urban impacts assessed in the built environment. Considerations that go into the modeling include the Soil and Water Assessment Tool (SWAT), monitoring information, and spatial analysis through GIS. Attributes of potential impairment were weighted through an attribute prioritization procedure with a panel of expert stakeholders, which is data intensive. The model was the napplied to all subbasins in the Chocopee River Watershed in Massachusetts, which has a diverse mixture of land uses and geographic features. This modeling procedure would be used in identifying baselines, prioritization policies, and adaptive community planning.
