3. Alberta Groundwater Information System
AER-AGS:
• Alberta Energy Regulator
• Alberta Geological Survey
Regulation process:
• Licensing groundwater abstractions
• Evaluating (cumulative) effects of abstractions
→ Need for a consistent and tranparent regulation process based on
spatial temporal groundwater information
→ Need for an operational management/information system

4. Operational water management system

5. FEWS
FEWS = Forecasting, Evaluation and Warning System
(previously: Flood Early Warning System)
• Operational information system
• Integrator of data and models
• Scenario analysis
• Structured work processes
• Pre-defined modeling processes and displays
• Highly configurable: tailor made to the needs of the users

6. Chautauqua
Education movement in North
America during the late 19th
and early 20th century. The
chautauqua message of
“progress and democracy”
relates perfectly to the
objectives of the Alberta
groundwater information
system: innovation,
transparency and openness
to a broad audience.

10. iMOD scenarios
1. What-if scenario with new abstraction:
• Application from industry for groundwater abstraction(s)
• Scenario editor for specifying new abstractions
→ automatically converted to iMOD WEL package
2. Reserves forecast:
• Future scenario of oil reserves exploitation = scenario of new
groundwater abstractions
• Shape file is provided by reserves forecast group of AER
→ automatically converted to iMOD WEL package

21. Advantages of iMOD in Chautauqua system
iMOD can be easily run from FEWS:
• IDF files can be imported and exported by FEWS
• Adapters between FEWS and iMOD are simple
Scenarios:
• Defining scenario templates by (small) differences in iMOD runfiles
• iMOD run file makes it easy to run user-defined scenarios
• Sub-modeling and scaling capabilities of iMOD can be exploited
iMOD displays:
• 2-D and 3-D viewer started from toolbar buttons in FEWS
