EnviroAtlas and Big Data in Watersheds
Instructors: Anne Neale, Jessica Daniel, and Megan Mehaffey (EPA)
11 a.m. – 2 p.m.
This half day workshop will demonstrate the U.S. EPA’s web-based tool, EnviroAtlas. EnviroAtlas provides geospatial data, easy-to-use tools, GIS toolboxes, and other resources related to watershed science and ecosystem services. Participants will see live demonstrations of the EnviroAtlas Interactive Map and its analysis tools, and do a deep dive into some of the 400+ available data layers. Participants will learn how EnviroAtlas data can be used in research and different decision contexts, and get a sneak peek at upcoming additions. Attendees don’t need to have a GIS background.
Introduction to the Water, Energy, and Biogeochemical Model (WEBMOD)
Instructor: Rick Webb
3 p.m. – 6 p.m.
This half day workshop will demonstrate how WEBMOD simulates flows of water, major ions, stable isotopes, and temperature for a natural watershed draining the continental divide in Colorado and fields irrigated with water from the Yakima River in Washington. The course will be taught by Richard Webb, the principal developer of WEBMOD and author of the Users Manual. Participants will be provided with background theory, software and input files and learn how to run the model in batch mode and within a Graphical User Interface. WEBMOD can provide the user or water manager with robust predictions on expected changes in water quantity and quality given a variety of scenarios of changing climate, population, and land use.
Big Data in Watersheds: Integrating Wetlands and Floodplains in Hydrologic Modeling
Instructors: Adnan Rajib, Qiusheng Wu, and Qianjin Zheng (Texas A&M University)
11 a.m. – 2 p.m.
Floodplains and wetlands have considerable effects on watershed hydrology, biogeochemical cycling, and ecology. Complex GIS formats, large data volumes, and inconsistency with the models’ spatial resolution and source-code have made floodplain and wetland integration in watershed models a “Big Data” problem.
In this half day workshop, we address these issues through the introduction of a coupled next-generation 100-year floodplain data layer and topographic approach for spatially explicit estimation of floodplain and wetland water storage. The workshop will include a hands-on interactive session, introducing a new semi-automatic tool which extracts the floodplain boundary and wetland water storage data for any given watershed via simple user commands in a web-based interface and seamlessly integrates the data in a user-provided hydrologic model. We will prototype this data-model integration architecture using SWAT, concurrently providing examples for other commonly used hydrologic models as well. Attendees will increase their geospatial representation/information and modeling capacity to efficiently quantify the role of floodplains and wetlands on landscape ecohydrological processes.
