Objective:
The overall objective of this proposal is to develop a predictive landscape simulation model, incorporating non-linear feedbacks, of the ecological and geomorphological consequences of climate-induced sea-level rise and river flow alteration in two of the most ecologically significant estuarine systems in Puget Sound, Padilla Bay and Skagit Bay. We will use the model to guide the course of restoration and management efforts, given climate change, as they relate to salmon habitat in Puget Sound.Progress Summary:
All of the field data required for all model (hydrodynamic, sediment dynamic, and relative elevation model (REM)) calibration and initialization has been collected and processed. Additional sediment data will be collected during the summer, because we have the luxury of another summer field season. Essentially, we will continue collecting the same kind of data that was collected during years 1 – 3 (sedimentation in Padilla Bay and we will collect a few more sediment cores in the Skagit Delta). The hydrodynamic model is complete and running. The REM model is complete and running. As a first step, sea level rise scenarios for Padilla Bay model (minus the hydrodynamics linkage), were run. An example of the output is shown in Figure 1. The GIS grid system for the entire Skagit system has been completed as well. Two peer-reviewed publications, highlighting our work thus far were published in the journals Ocean Modelling and Ecological Modelling. What remains for 2010 – 2011 is to inititialize and calibrate the sediments dynamic model with the data that was collected and processed last year, and then to link the three models and run the sea-level rise scenarios for the entire Skagit system (of which Padilla Bay is part).Figure 1a.
