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.

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.

Stability Design and Freeboard Criteria
Auxiliary spillway hydrograph is the same as Stability Design terminology used in WinTR-20.

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.
