High-resolution hydrologic modeling of Glacier Bay National Park
OVERVIEW Include a paragraph that explain the overview of the project to be awarded. Freshwater runoff plays a first order role in controlling the spatial and temporal distribution of water column properties (salinity, temperature, density) in the waters of Glacier Bay National Park and Preserve (GBNPP). Runoff also strongly controls circulation patterns and residence times. These physical oceanographic processes are linked in many ways to ecological processes, demonstrating the broad impact of freshwater runoff on Glacier Bay. Streamflow is undersampled in Alaska in general and in GBNPP in particular. As a result, the hydrologic budget of Glacier Bay can not be determined through monitoring alone, and a modeling campaign is needed. Glacier Bay and Oregon State University will jointly develop a physical process-based hydrologic model for GBNPP that models snow and ice melt, and that routes runoff through the landscape to the coastline. The model will be highly resolved in space (100-500 m) and in time (daily step) allowing for estimates among and within seasons and years, and can accommodate individual rainfall events. The model will ultimately be validated using physical oceanographic data collected by park staff. Since runoff is strongly controlled by the precipitation and weather data, we will make model runs using three different weather products (NARR [North American Regional Reanalysis], MERRA [Modern-Era Retrospective Analysis for Research and Applications], and PRISM [Parameter-elevation Relationships on Independent Slopes Model]). The ensemble of data sets will help to quantify the uncertainty in runoff associated with uncertainty in forcing weather data. Outcomes of this project will include a dataset in netcdf format covering the entire GBNPP watershed that specifies runoff on a daily time step for a 30-year hindcast period. â₏™Derivedâ₏™ products will also include files describing the runoff extracted only at coastline grid cells to allow for the specification of the runoff into Glacier Bay. These data files will be suitable for immediate inclusion into an oceanographic model of the bay by other interested parties. Finally, a number of visual materials will also be generated based on input from park management and interpretation staff, including images (at a given time step, for example) and movies (covering a year, or the entire model period) that demonstrate the rich behavior of snowfall, icemelt, and runoff. STATEMENT OF JOINT OBJECTIVES/PROJECT MANAGEMENT PLAN NPS and Oregon State University will jointly develop a hydrologic model for GBNPP that models snow and ice melt, and that routes runoff through the landscape to the coastline. This collaborative project will improve our understanding of the present levels and distribution of runoff and how levels and distribution can change in response to changing precipitation, temperature and land cover. The variety of products produced by this project will contribute to greater public understanding of the hydrology of the system and how changing climate conditions can influence this critical component of the ecosystem. Explain the mutual and cooperative participation of the project to be awarded. 1. Generate a 30-year dataset on streamflow for the entire GBNPP watershed. This dataset will have a daily time step and will have a spatial resolution of 100-500 m. 2. Convert model results into netcdf format, which is a machine-independent data structure preferred for array-oriented data. 3. Generate model datasets for three widely-used weather reanalysis products. 4. Calibrate and validate the model results with available field data (subject to data availability). 5. Produce informative and visually appealing media (images, animations) related to the hydrologic cycle of Glacier Bay. 6. Present results to park staff and to park visitors.
