3. Background Major precipitation event in October 2013 Led to flooding in Freeman Ranch BeforeAfter

4. Background People were trapped at the ranch Total fence property damage est. $140,000

5. Summary GeoTrek : The Next Generation create flood-prediction model Use a Geographic Information System (GIS) Will aid Freeman Ranch to minimize repercussion from future flood events

6. Purpose Primary goal is to create a flood prediction model for Freeman Ranch Minimize damage Make Freeman ranch more flood resistant Propose possible construction reinforcement of roads and fences that are more vulnerable Secondary goal is the use of the model to make Freeman Ranch a safer environment Help know which roads are inundated to safely relieve personnel Which pastures are most vulnerable to flooding so all livestock can be removed from the area.

7. Scope Study areas within Freeman Ranch Fences and locating areas where they are at high risk Access roads for employees Physical infrastructure The timespan is variable: a lot can affect how quickly waters can rise with a flash flood event in Central Texas.

8. Scope

9. Primary Research Cellular Automation-It consists of a regular grid of cells, each in one of a finite number of states, such as “On” and “Off” (in contrast to a coupled map lattice). The grid can be in any finite number of dimensions. For each cell, a set of cells called its neighborhood (usually including the cell itself) is defined relative to the specified cell.

12. Methodology 1. Gather appropriate data Determine variables needed for analysis

13. Methodology 2. Process data  Create a grid system from DEM  Project other data in ArcMap

14. Methodology 3. Conduct GIS analysis  Assign a value to each cell in the grid  Mathematically determined

15. Methodology 3. Conduct GIS analysis  Use time variable to visualize spread

16. Methodology 3. Conduct GIS analysis  Project infrastructure data to determine which areas will be affected

17. Methodology 4. Compare findings to known data  Compare results to known data  Iterate step 3 until results are accurate

18. Methodology 5. Compile final deliverables  Create a real-time flood model for users  Will aide in determining which areas will be affected at what time

19. Implications The results of our flood prediction model can be used to determine what fences, pastures, and roads become jeopardized during a potential flood. The model will be able to simulate how flood waters will rise and what areas become inundated. It will be possible to determine what areas of freeman ranch are inaccessible or need to be evacuated of personnel and livestock.

21. Timetable 1/22 – Receive request for proposal from client 2/12 – Proposal to client 3/26 – Progress report to client 5/2 – Final project presentation to client Weeks with important dates

22. Final Deliverables Final report and an accompanying PowerPoint Presentation 2 CD/DVDs containing: All data Metadata All reports Digital copy of poster PowerPoint Presentations Professional poster outlining the project and its purpose Web portal for use by the Freeman Ranch

23. Conclusions GeoTrek : TNG will use a GIS to create a flood-prediction model for Freeman Ranch Use terrain, weather, and infrastructure data Use the concept of cellular automation to model the flood Aid Freeman Ranch assessing areas of potential risk to help minimize damage from future flood events
