Approach
The following table summarizes the approach to addressing the Task 50.2 objectives, as
presented in this technical memorandum.
Section Description
1.0 Development of Enhancement Guidelines
2.0 Process Enhancements
2.1 Model Input Process Enhancements
2.2 Model Output Process Enhancements
3.0 Modelin Gra hical User Interface Selection
Section 1.0 discusses the guidelines that were developed in collaboration with the State to
identify and prioritize potential enhancements. Section 2.0 discusses specific enhancements to
the modeling process. Section 3 reviews the candidate GUI software for the SPDSS and
recommends a package for selection.
1.0 Development of Enhancement Guidelines
Potential enhancements to the data centered modeling process were developed in two working
sessions CDM facilitated with State personnel who have detailed working knowledge of the
RGDSS modeling process and of the SPDSS modeling goals. State staff who participated in
these meetings included:
^ Ray Alvarado -Colorado Water Conservation Board
^ Andy Moore -Colorado Water Conservation Board
^ Ray Bennett -Colorado Division of Water Resources
^ Brian Ahrens -Colorado Division of Water Resources
Building on the existing data centered modeling process that has been implemented by the State
for the RGDSS, as summarized in the Task 50.1 TM, these meetings included discussions of
individual software tools and the overall modeling process. During these sessions, the State's
preferences for the groundwater modeling process were developed and include the following
guidelines. The guidelines were used to identify potential process enhancements.
^ Location information on structures, irrigated parcels, land use, wells, canals and streams will
be maintained in the GIS repository. Stream flows, diversion records, water levels and other
observations will be maintained in HydroBase. Point locations for features such as wells,
diversions and stream gages are maintained in HydroBase and used to generate GIS
coverages.
^ Software tools will process data directly from source databases or GIS coverages, where
possible, to minimize the need for manual modifications to files, increase efficiency in
