IAN Seminar Series 2013

The goal of the IAN seminar series is to provide concise, thought-provoking ideas relating to Chesapeake Bay science and management. Short presentations (15 minutes maximum length) are immediately followed by a lunchtime discussion of the topics raised by the presenter. The discussion is summarized and is posted along with a pdf version of the seminar slides. The seminars are captured on video and posted under a Creative Commons license so they can be freely shared.

This mandate presents an ideal opportunity to integrate watershed science and management. State guidelines currently suggest using the Maryland Department of Planning (MDP) Non-Point Source Assessment Spreadsheet to downscale annual average predictions from the Chesapeake Bay Program\'s HSPF Phase 4 model. The assessment tool is intended to help land managers minimize surface water quality impacts by providing nutrient load estimates under current and future land use scenarios. We implemented the MDP tool for a Maryland town, along with three watershed models, GWLF, SWAT, and the CBP-HSPF5, The differences in predicted water quality among alternative land use scenarios being considered by town planners (including a no change scenario) were small, especially compared to the variation among models in the predictions for any single scenario. In addition, all the models agreed that nutrient discharges originate primarily from outside the planning jurisdiction. Because of the dominance of external sources and the similarity among scenarios, the predicted impacts from non-point source pollution have had little influence on the Town\'s land management decisions.
