1. WinTR-20 PS, SD, FB HydrographsJune 20151 WinTR-20 Principal Spillway, Stability Design, and Freeboard Hydrographs Presented by: WinTR-20 Development Team

2. WinTR-20 PS, SD, FB HydrographsJune 2015 2 Lesson Objectives 1. Introduce NRCS Technical Release 60 (TR-60) criteria for developing structure design hydrographs. 2. How to input data for Principal Spillway, Stability Design, and Freeboard storms to the Win-TR20 computer program. 3. How to develop PS, SD, and FB hydrographs for import to the WinDAM computer program.

3. WinTR-20 PS, SD, FB HydrographsJune 2015 3 What is TR-60 ? TR-60 includes criteria for designing dams. The latest version is 2005. Specifically of interest to hydrologists are criteria for selection of rainfall amount for the design storms.

4. WinTR-20 PS, SD, FB HydrographsJune 2015 4 TR-60 Hazard Classification

5. WinTR-20 PS, SD, FB HydrographsJune 2015 5 Principal Spillway Criteria Typical data source is NOAA Atlas 14 if available.

6. WinTR-20 PS, SD, FB HydrographsJune 2015 6 PS Criteria – Quick Return Flow

7. WinTR-20 PS, SD, FB HydrographsJune 2015 7 PS Criteria – Runoff Volume

8. WinTR-20 PS, SD, FB HydrographsJune 2015 8 PS Criteria – Ratio 1-day/10-day Q

9. WinTR-20 PS, SD, FB HydrographsJune 2015 9 Stability Design and Freeboard Criteria Auxiliary spillway hydrograph is the same as Stability Design terminology used in WinTR-20.

10. WinTR-20 PS, SD, FB HydrographsJune 2015 10 Stability Design and Freeboard Criteria  TR-60 includes a detailed list of data sources for locations in the United States.  NOAA Atlas 14 is typical data source for 100-year precipitation if available.  NOAA Hydrometeorological Series Reports (HMR) are typical data sources for probable maximum precipitation (PMP) if available.
