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. 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.
Mr. Singhofen is the president, founder and owner of Streamline
Technologies, Inc., an engineering software development firm located
in Winter Springs, Florida. He has been a water resources professional
for more than 35 years specializing in distributive physically-based
integrated modeling of large-scale surface and groundwater systems.
Mr. Singhofen's interests include precipitation driven 2D surface
flow, flexible triangular computational meshes, integrated 1D/2D
surface flow, integrated surface water and groundwater flow, use
of open source data for model construction, continuous simulation,
impacts of sea level rise on groundwater and surface water systems
in coastal areas, wetland hydroperiod assessments, wetland restoration
metrics, and holistic modeling approaches.
Title: GIS Support for Hydrologic and Hydraulic
Objectives: Understand the key concepts in GIS support for
1D and 2D hydrologic and hydraulic modeling:
1. Differences in terrain processing for hydrologic and hydraulic
analyses and for 1D and 2D modeling approaches.
2. Drainage system determination and characterization.
3. Integration of natural and man-made drainage systems into a single
4. Derivation of 1D and 2D H&H modeling elements: pre- and post-processing.
5. GIS as model integration and automation infrastructure.
6. 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, HEC's RAS, HMS, GeoRAS,
and GeoHMS, 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
1. Review of spatial data for H&H analyses.
2. Representation of built and natural environments in GIS and numerical
3. Arc Hydro for terrain preprocessing and developing GIS infrastructure
for H&H modeling support
4. Principles of model integration.
5. USGS Streamstats - GIS for statistical hydrology (peak and low
6. HEC-HMS and HEC-GeoHMS - GIS and deterministic hydrology.
7. HEC-RAS and HEC-GeoRAS - GIS and 1D hydraulic modeling.
8. 2D integrated hydrologic, hydraulic and groundwater modeling
9. 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.
