1. WALLER CREEK FLOODING ALONG 45 TH STREET Design Project C E 365K- Hydraulic Engineering Design Group 11: Scott Cameron, Matthew Strumeyer, Juhn-Yuan Su Dr. D. R. Maidment

2. OVERVIEW Discussion on Location Hydrodesign Process: 1.Representation 2.Process 3.Evaluation 4.Change 5.Impact 6.Decision Recommendations

3. WALLER CREEK Flooding as a Fundamental Problem (Primary focus of Project) 2/3 of Natural Disasters due to Flooding Examples of Flooding Disasters: Halloween Flood (10/31/2013), Sandy (2012); a lot of them over the world! Water Quality another issue (will not be the primary focus of project) Buildings simply “getting rid of water as quickly as possible” NOT the primary emphasis for this project

4. AREA OF STUDY FOCUS OF PROJECT: 45 th Street and Avenue F Area Apartment Complex

5. REPRESENTATION How can the Study Area be Described? Waller Creek through Avenue F and 45 th Street Approximately 22,500 feet from downstream of Waller Creek Reach Apartment on one side of creek and road on another

6. PROCESS How does the Study Area Operate? Waller Creek flows downstream along the route indicated Flows through the park Two Bridges: 45 th Street Avenue F Bridges

7. EVALUATION Is the Study Area Working Well? NO!!! The Apartment Complex Directly in the 25-year AND 100-year Floodplain Karl McArthur: Flooding Problems between 41 st and 47 th Street Particularly Area on the right

8. EVALUATION

9. Cross Section to Modify

11. CHANGE How might the Study Area be Altered? SOLUTIONS PROPOSED: 1.Do Nothing 2.Get Rid of the Apartment 3.Elevate the Apartment 4.Elevate BOTH the Apartment and the Road USE HEC-RAS for the Simulation Models

12. SOLUTION 1: DO NOTHING

14. SOLUTION 2: ELEVATE THE APARTMENT (RIGHT OVERBANK) Raise the Apartment by 2.5 Feet In HEC-RAS, Raise the Right Overbank (ROB) Decreases the Flow Area

16. SOLUTION 2 RESULTS Pros Lowered Top Width by 45 Feet for 5- year Return Period Allows greater Flow Velocity THOUGH Smaller Flow Area Cons Requires People to Move Out and then Move Back In Need a Machine to Literally Elevate the Apartment Need Soil Fill to Add Below the Apartment

17. SOLUTION 3: DESTROY THE OBSTRUCTION NO Change in Elevation of LOB or ROB Water Surface Elevations still the same

19. SOLUTION 3: DESTROY THE OBSTRUCTION Pros Flow Velocity has Decreased due to Larger Flow Area Less Worries on People along Waller Creek at Avenue F getting Flooded Cons Top Width Increased Significantly Where are all those people in the apartment going to go? MIGHT BE UT STUDENTS!!

20. SOLUTION 4: RAISE THE LEFT AND RIGHT OVERBANKS Raise Both Sides of the Channel by 2.5 feet Road Apartment Complex Helps solve issue on Flooding along Apartment and Road

22. Pros Significantly decreased the Top Width All to Top Width in the 40s feet Increased Flow Velocity though with Much Smaller Flow Area Cons Traffic Accidents due to Elevated Road??? Means: Need to Raise 45 th Street Upstream (cost-inefficient) Soil Fill Needed Cost- High; Need to Raise Apartment and Road SOLUTION 4: RAISE THE LEFT AND RIGHT OVERBANKS

23. Conclude: Solution 2 (Elevate Apartment by 2.5 feet) is the most cost-effective solution 2.5 Feet- Neutral Selection for Elevation Water-Surface Level for 100-year Storm Still Below Apartment SOLUTION CHOICE

24. PHOTO OF HEC-RAS MODEL

25. PROGRESS Auto-CAD Drawing of Waller Creek and Raised Apartment Elevation Needed! Incorporation into ArcGIS with the Raised HEC-RAS Model FOR MATT AND SCOTT: Please add any of the AutoCAD or GIS models with the solution if updated.
