Dr. Djokic is water resources practice manager for ESRI's Professional Services Division that develops Arc Hydro, HEC-GeoRAS and HEC-GeoHMS. He specializes in water, sewer, storm, and water resources GIS implementations. He is also involved in water resources development and marketing at the corporate level. As an applications designer and programmer, Dr. Djokic designs and develops GIS-based custom water resources solutions. He has extensive experience in developing GIS applications for water/wastewater and environmental resource management, particularly applications related to hydrology and hydraulics. He has an in-depth understanding of GIS and water resources that enables him to ensure that applications meet engineering requirements. Dr. Djokic has developed GIS implementation plans for several water resources agencies. The plans present an efficient and practical approach to GIS implementation and utilization in particular agency environment. He has also developed and is conducting Arc Hydro and Hydrologic and Hydraulic Modeling Using GIS classes, which present the database design, tools, and techniques for the successful implementation of GIS technology for various aspects of water resources analyses.

Title: GIS Support for Hydrologic and Hydraulic Analyses

Objectives: 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 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. Esri's Arc Hydro, HEC's RAS, HMS, GeoRAS, and GeoHMS, and Streamline Technology's ICPR 4G will be used to demonstrate the key concepts and capabilities.

Topics:

  • Review of spatial data for H&H analyses.
  • Representation of built and natural environments in GIS and numerical models.
  • Arc Hydro for terrain preprocessing and developing GIS infrastructure for H&H modeling support
  • Principles of model integration.
  • USGS Streamstats - GIS for statistical hydrology (peak and low flows).
  • HEC-HMS and HEC-GeoHMS - GIS and deterministic hydrology.
  • HEC-RAS and HEC-GeoRAS - GIS and 1D hydraulic modeling.
  • 2D integrated hydrologic and hydraulic modeling - ICPR 4G.
  • GIS for operational and design automation.

Outcomes: 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: 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.

Number of Students: The number of students will be limited to 40 and will be enrolled in the order of their registration.
