Workshops - SITES


This short course provides training in using the SITES program to hydraulically design dams using NRCS criteria.  Instruction is given on how the Integrated Development Environment (IDE) in which the Sites program operates guides the user through data entry and assists in interpreting output.  Training is given on how to use the full-featured rainfall-runoff routing program for watershed (TR-60) dam design and analysis as well as data entry for CO-01 (378) dam design.  The participant will learn to evaluate the sensitivity of input variables on the output and/or compare various design alternatives.  Instruction on how to use on-line help for both input and output screens is provided.  Participants will learn how to handle sites in series, but focus is on the design or analysis of the most downstream structure.  Classroom exercises are given to practice the design of complex watersheds having upstream structures, sub-watersheds, and channel reaches.  Participants will also use the SITES software for example exercises of dam designs which include use of the built in erosion model for evaluation of potential spillway breach.




Upon completion of this training, the participant will be able to use the SITES program to hydraulically design a TR-60 dam or a 378 farm pond.




The participant should have a working knowledge of basic hydrologic and hydraulic procedures used in dam design, including design rainfall depth, rain distribution, curve number, and time of concentration selection.  Unit hydrograph and reservoir routing concepts should be reviewed before attending.
