| Description | The Puget Sound Characterization program has tested the potential application of a mid-scale tool known as the Hydrologic Condition Index for use throughout Puget Sound watersheds. The HCI index is based on detailed hydrologic modeling that generates coefficients predicting the “flashiness” of stream flows that a given combination of land cover and surficial geology would likely produce in a watershed. Preferred methods for calculation of the index are described based upon initial testing and validation using stream gage data in a series of watersheds in central Puget Sound. Testing of the HCI index for “alternative futures” applications indicate potential as a useful tool in assessing implications of development patterns on the hydrologic health of a watershed. Use of this tool can assist local governments locate future development in a manner that minimizes impacts to watershed hydrological condition. Recommendations for further development of the mid-scale tool so that it can be applied regionally are provided. |
