
Identify areas that are sensitive to development or other land
use changes.
Specifically determine which groundwater and surface water
areas are most vulnerable to non-point source pollution,
taking into account various hydro-geologic and geographic
criteria.
Use Geographical Information Systems to delineate the most
vulnerable regions where development should not occur.
The analysis will be based on the following data:
 Ground Vegetation
 Soil Hydraulic Conductivity (KSAT)
 Cave Density (Groundwater map only)
 Soil Thickness/Depth
 Floodplains
 Slope
All data is provided by Marston & Marston; excluding vegetation,
which was acquired through the seamless data distribution server
on the USGS website
Reference layer (not put into vulnerability
study)
 Areas where development is obstructed

(FEMA floodplains)

 Complete Data Set
 Steepest Slopes = Most Vulnerable Area

 Both groundwater and surface water
 Slopes will be evaluated relatively
○ Between 0 = low and 1 = high


Each data set that we are evaluating will be divided into a
continuous grid comprised of one square kilometer cells.
Each grid will be assigned a vulnerability score.


Groundwater Vulnerability
 Evaluate soil thickness, soil KSAT, slope, land cover, and cave
density.
 Each item will be analyzed for its vulnerability criteria and
assigned a value from 0-1.
 A value of 0 indicates the least vulnerable areas.
 A value of 1 indicate the most vulnerable areas.

Surface Water Vulnerability
 Evaluate soil thickness, KSAT, slope, and land cover.
 Each item analyzed for vulnerability criteria and assigned a
value from 0-1.
 A value of 0 indicates the least vulnerable areas.
 A value of 1 indicate the most vulnerable areas.

Work Completed up to Today

Acquired 90% of data sets
 Provided by Scott Appleton of Marston & Marston
 Vegetation data obtained from USGS
 In the process of retrieving missing data

Examined data layers and started classifying

Completed initial proposal
 Established goals and objectives
Final Deliverables

The final product will include the following:
 Detailed final report discussing findings.
 Groundwater vulnerability static map.
 Surface water vulnerability static map.
 Website summarizing final report information.
 Web maps with the ability to click and focus on specific areas.
 Two posters summarizing the results of our analysis.
Potential Problems / Challenges

Missing Data Creating Deceptive Final
Product
 Where data is missing the vulnerability score
will be based on fewer criteria
 Example: Mason County
○ Potential Solution = Clearly highlighting the
areas that are assessed on less than 5 (or in
the case of surface water 4) criteria and state
which criteria were used for analysis
Conclusion

Rapid growth rates in the Central Texas region and the desire to
maintain quality water resources have motivated this analysis.
Through a geospatial investigation, SMART will highlight areas in
the Central Texas region where groundwater and surface water
resources are vulnerable to non-point source pollution. The maps,
along with accompanying products, will be delivered to the Hill
Country Alliance and used as a reference for future development in
the Central Texas area.
