demonstrate use of GIS for water resources
management
 Understanding the difference in the use of GIS
between U.S. and international (developing)
countries

11. Presenting Downscaled Climate Change
Impacts on Spatial Extent of Wetlands
Station 79897.28
From Station 84890.15 to 79406.8
Wetland Area (Baseline) = 1.32 sq mi
Wetland Area (Projected) = 1.48 sq mi
Percent Increase = 12.1 %
Floodplain Width (Station 79897.28) = 1029 ft
Increase in Width (Station 79897.28) = 455ft

12. Managing Workflow for Small Stream
Maintenance Program

13. Managing at the Enterprise FEMA’s Map

14. Use of GIS Technology Within the Context of
a Gartner Hype Cycle
U.S
Expectation
Developing
Countries

15. Typical Issues/Constraints – Developing
Countries
 Data Constraints
 Data availability and accessibility
 Data accuracy
 Data resolution
 Data completeness
 Modeling Constraints
 Limited Technical Expertise and Capacity
(including use of GIS for Analysis and
Modeling)
 New to Watershed Modeling
 Historically, focusing on receiving water modeling

16. Immediate Potential Applications of GIS in
Developing Countries
 Disaster Risk Reduction
 Flood Risk Reduction
 Water Pollution Reduction

17. Mega-Cities of Developing Countries
Investments on Wastewater and
Sanitation Infrastructure and Services

18. Basin-wide Water Resources Management in
Morocco
Sebou River Basin

19. Catastrophic Flooding in the Gharb Plain

20. Pollution Hotspots in the Basin

21. Decision and Analysis Support Framework
GIS-Enabled

22. GIS-Based Modeling System
Floodplain Mapping
Water Quality Impacts Assessment Flood Forecasting

23. Summary
 Use of GIS has increased the effectiveness of
organizations to manage water resources
especially in the U.S.
 Technical capacity, data and resource
constraints are the main hurdles for
developing countries before they can fully
reap the benefits of GIS
