Water Rights Analysis Package (WRAP)

• Created by Dr. Ralph Wurbs of the Texas Water Resources Institute at Texas A&M

• Used by TCEQ with WAM system• Digital management of water rights• Replaces manual map tracing method• WRAP Display tool shows results in GIS

– Problems with current WRAP version

• Test site: Big Cypress Creek Watershed– near Mount Pleasant, TX

Addressing Inconsistencies

• Inspect GIS attributes

Addressing Inconsistencies

• Examine data origins (WRAP output file)

Percent of Storage (July 1996, old WRAP version)

Preliminary Rectification

Percent of Storage (July 1996, new WRAP version adjusted)

• Results after changing program code

No change = Success!

Preliminary Rectification

• Inspect GIS attributes

Looking Forward

• Preprocessing may be automated• Time series graphs can be improved• Programming platform will be upgraded• Graphical user interface (GUI) will be

enhanced• Elevation-Area-Capacity curves for small

reservoirs will be explored

Conclusion

• WRAP changes affect the Display tool• Code can be modified• Subsequent results are the same• Additional features can be added
