20. 20 PS Type Common

21. 21 PS Inlet K e -energy loss inlet entrance to just inside the conduit See NRCS Design Note 8

22. 22 PS Conduit Constant CL pipe outlet

23. 23 Valley Elevations AS can erode down to “Elev of Valley Floor” Dam Height for classification Profile for embankment quantity computation (optional)

26. 26 AS Crest Options

27. 27 AS Crest Data PSH checked on Global WS Data  SITES sets crest of AS PSH unchecked on Global WS Data screen  User specifies AS crest elevation

28. 28 Tie Station Tie station is downstream end of level crest of auxiliary spillway Ties auxiliary spillway crest information with geologic materials

34. 34 Vegetal Cover Factor & Maintenance Code Used to compute effective stress on erodible boundary for uniform vegetal conditionsUsed to compute effective stress on erodible boundary for uniform vegetal conditions Discontinuities in cover minimize effect of cover factor (MC 2 or 3)Discontinuities in cover minimize effect of cover factor (MC 2 or 3)  Erosion occurs in areas without cover See Ag Handbook 667See Ag Handbook 667

35. 35 Potential Rooting Depth & Topsoil Diameter Rooting Depth > 1’ – protected Rooting Depth < 1’ – strips away Topsoil representative diameter only for stability analysis  Constructed exit channel only (no fill in natural ground)  Coarse-grained materials only (d 75 >0.05 inches)

36. 36 AS Cross-section Trapezoidal 3 Methods Peak SDH

37. 37 AS Materials

38. 38 AS Materials Notes Integrity evaluation of auxiliary spillway  Describe materials exposed to erosive attack  Geologic profile through spillway  Spillway centerline profile??  Erosion occurs at weakest materials  Input weakest geologic profile in spillway Material Description only for labeling  Be descriptive  “CL1, CH2, Limestone” are better than 1, 2

39. 39 PI - Dry Density - % Clay PI for time of phase 1 (surface- vegetation) failure PI most important for materials initially exposed at spillway surface Dry density and percent clay determe the erosion rate coefficient of downcutting for concentrated flow and headcuts in cohesive materials Use either % clay or detach rate (jet erosion test)

40. 40 Rep Diameter & K h Size of material detached as single unit  Fine grained materials & sediments - d 75  Large materials -  Governs computed threshold where surface shear detaches material in concentrated flow or headcut downcutting Headcut erodibility index (K h ) governs threshold and rate for headcut advance

48. 48 After the desired input data set is developed, the data is normally stored under a new file name. Save As...

49. 49 Input Tips Create project directory for each dam Select projects from MRU list Descriptive file names help Use comments to document the alternative Let SITES be the file manager Send input file (*.d2c) to reviewer

50. 50 Typical Opening Sequence Open Project Directory (select from list) Open File (select file, NOT folder)  SITES build creates a folder with same name as input file Continue – Next Screen  Schematic Dbl-click design structure  User spends most time editing design structure

51. 51 Jump to Screen Right-click in empty area Select specific screen

52. 52 Typical Post-edit Sequence Schematic Home Screen Save As... (enter filename) Build File  SITES builds folder and places all output files into the folder
