Workshop 1: GIS Support for Hydrologic and Hydraulic Analyses - $89.00
Sunday, March 22 | 8:00 AM - 5:00 PM | Flyer
Objective: Understand the key concepts in GIS support for 1D and 2D hydrologic and hydraulic modeling:
- Differences in terrain processing for hydrologic and hydraulic analyses and for 1D and 2D modeling approaches.
- Drainage system determination and characterization.
- Integration of natural and man-made drainage systems into a single hydro modeling unit.
- Derivation of 1D and 2D H&H modeling elements: pre- and post-processing.
- GIS as model integration and automation infrastructure.
- Roles of GIS and numerical models – single GIS environment – support for many H&H models and follow-up analyses.
Background: As a technology for spatial data storage, processing, and visualization, GIS offers many capabilities that can be used to support 1D and 2D H&H modeling. This workshop presents GIS techniques that can be used for terrain analyses, spatial and temporal integration, hydrologic and hydraulic characteristics extraction, 1D and 2D numerical model input and output, modeling process automation, and result mapping. While Esri’s Arc Hydro, NWS NWM, and Streamline Technologies’ ICPR4 will be used to demonstrate the key concepts and capabilities, the concepts are general and can be used for support of any H&H, and in general, water resources model.
- Review of spatial data for H&H analyses.
- Representation of built and natural environments in GIS and numerical models.
- Principles of model integration.
- Arc Hydro for terrain preprocessing and developing GIS infrastructure for H&H modeling support.
- 2D integrated hydrologic, hydraulic and groundwater modeling – ICPR4.
- GIS for operational and design automation.
The expected outcomes from the workshop are that participants will understand the fundamental principles of GIS and H&H modeling integration, will see GIS and modeling tools in action, will gain appreciation for what GIS can and cannot do for modeling, understand differences in 1D and 2D modeling support, and understand the GIS and model limitations with respect to quality of supporting data.
Attendee Requirements: Limited to 40 attendees, the target audience includes hydrologists, water resources engineers and managers, GIS analysts, and anyone interested in learning what GIS can do for H&H data collection, preparation, model assembly, and result processing. Attendees should have some background in GIS and/or H&H modeling. The participants will not be using computers during the workshop, so experience with particular GIS or modeling software is not required.
