WinTR-20 PS, SD, FB HydrographsJune WinTR-20 Principal Spillway, Stability Design, and Freeboard Hydrographs Presented by: WinTR-20 Development Team
WinTR-20 PS, SD, FB HydrographsJune 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.
WinTR-20 PS, SD, FB HydrographsJune What is TR-60 ? TR-60 includes criteria for designing dams. The latest version is Specifically of interest to hydrologists are criteria for selection of rainfall amount for the design storms.
WinTR-20 PS, SD, FB HydrographsJune TR-60 Hazard Classification
WinTR-20 PS, SD, FB HydrographsJune Principal Spillway Criteria Typical data source is NOAA Atlas 14 if available.
WinTR-20 PS, SD, FB HydrographsJune PS Criteria – Quick Return Flow
WinTR-20 PS, SD, FB HydrographsJune PS Criteria – Runoff Volume
WinTR-20 PS, SD, FB HydrographsJune PS Criteria – Ratio 1-day/10-day Q
WinTR-20 PS, SD, FB HydrographsJune Stability Design and Freeboard Criteria Auxiliary spillway hydrograph is the same as Stability Design terminology used in WinTR-20.
WinTR-20 PS, SD, FB HydrographsJune 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.
