Dean Djokic, Ph.D.
Water Resources Practice Manager
Redlands, CA 92373
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
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.
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
HEC-RAS and HEC-GeoRAS - GIS and 1D hydraulic
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
Number of Students: The number of students will be limited
to 40 and will be enrolled in the order of their registration.
