    2. GEOPAK Culvert Beats Nomographs Powerful tool for design & analysis of culverts. Interacts with GPK, GSF, GDF, and/or tin files.

    3. GEOPAK Culvert Used on 2 Recent Projects Fort Smith, AR Access & Construction Roads for Dam Improvements Project for City of Fort Smith, AR. US 169 Oologah to Talala, OK Improving Rural 2-Lane Road to 4-Lane Freeway for ODOT.

    4. Culvert Expedites Pipe Design at Fort Smith Project Schedule Compressed by Changes in Scope. 1.5 Miles of Access Roads 4.5 Miles of Construction Roads & 15 Cross Road Culverts. Design Engineer Inexperienced in H&H Design.

    5. Good GEOPAK Design Starts with the Project Manager Opening Project Manager Provides a Smooth Setup of GEOPAK Preferences and Directories for Use in GEOPAK Drainage & Culvert.

    6. Culvert Located In GEOPAK Drainage

    7. GEOPAK DRAINAGE TOOL BAR Drainage Project Must Be Added or Opened Before Culvert Can Be Used.

    8. Open GEOPAK Drainage File Contains All Previously Developed Information. Might Want to Keep a Spare.

    9. Preferences Set the Project Standards Preferences Defined on a Project by Project Basis. Fort Smith Preferences Different from US 169 Preferences.

    10. Units A Critical Preference/Standard

    11. Project Components Where to Find Critical Project Data Locations of Drainage Library Files (DLB), GPK No., Drainage Cell Library, Site Modeler File (GSF), Criteria Directory, and Superelevation Shapes.

    12. Rainfall Parameters for Runoff Calculations May or May Not Be Required With Culvert. Used in Runoff Calculations Rational Method or SCS TR-55.

    13. Land Use Options for Runoff Calculations

    14. Frequency Options for Runoff Calculations

    15. Intensity Option for Runoff Calculations

    16. Junction Losses for Storm Sewer Systems

    17. Inlet Options for Storm Sewer Systems

    18. Node Options for Culvert Headwalls

    19. Link Options Culvert Considers a Pipe a Link

    20. Design Symbology Paints a Pretty Picture

    21. Drainage Library 2nd Key Project Component Further Defines Project Standards, such as, Rainfall Data, Land Use, Runoff Coefficients, Nodes (Headwalls), Links (Pipes), & Spread Sections.

    22. Rainfall Data & Land Use Data for Runoff Calculations Rainfall Data to Develop Intensity Data & Curves. Land Use Data to Develop Runoff Coefficients.

    23. Headwalls Primary Node Type for Culverts Other Inlet and Outlet Nodes for Storm Sewer Systems.

    24. Node Items Can Be Modified Node Items Can Be Added Copied Pasted Modified Deleted and Printed.

    25. Links Come in a Variety of Shapes

    26. Links Come in a Variety of Materials

    27. Link Items Can Be Modified Link Items Can Be Added Copied Pasted Modified Deleted and Printed.

    28. Pipe Arch Links Require Dimensions Input of RC & CM Pipe Dimensions Required for Pipe Arch Items for Drainage Library.

    29. Culvert Located Under Tools on Drainage Tool Bar

    30. Culvert Tool Bar Add Delete Modify ID Selected Culvert Close Culvert Session Show Cross Section Center Plan On Culvert

    31. Add Culvert Tool Most Recent Culvert Data Appears in Name and Description Input Blanks. Must All Be Replaced.

    32. Edit Culvert Tool Presently 5 Data Tabs 1st Data Tab Parameters Input Discharge & Tailwater Elevation

    33. Configuration Tab Inputs Culvert & Headwall Characteristics Culvert Shape Material Size No. of Barrels Mannings n and Headwall Entrance Type

    34. Headwall Location Tab Allows a Variety of Input Sources Can Be Tied to GEOPAK Reference Chain MicroStation Element TIN File Site Model or Input Data from User

    35. Overtopping Tab Not Used on Fort Smith Project

    36. Computation Tab Analyzes and Outputs Data

    37. Typical Data Output File for Lake Fort Smith Cross Road Culvert

    38. US Highway 169 for Oklahoma DOT Improving 8 km of Rural 2-Lane Road to 4-Lane Freeway. 14 Cross Road Culverts & 16 Section Line/Drive Culverts. 4 Cross Road Culvert Impacted by Backwater from Existing Backwater from Downstream RR Culverts.

    39. Project Manager Opened to Set Project Standards

    40. US 169 - Metric Project

    41. US 169 - Different Project Components ODOT Specific Cell File. No Criteria File Directory. No Superelevation Shape Files

    42. Different Design Symbology = Different Picture to Meet ODOT Requirements

    43. Rainfall Data from ODOT Hydrology Manual

    44. Numerous Different Headwall Nodes on Project Cross Road & Side Road Culverts Require a Number of ODOT Standard Headwalls. Most Side Road and Drive Culverts Require Sloping Headwalls.

    45. ODOT Cell Library Developed for Headwalls

    46. Project Included a Number of Metric RCB Culverts

    47. Discharge & Tailwater Elevations Developed by Spreadsheets Outside of GEOPAK

    48. Variety of Culverts & Headwalls Used on Project

    49. US 169 - Typical Headwall Location Tab Headwalls for Cross Road Culverts Dynamically Placed. Headwalls for Section Line/Drive Culverts Placed by Keyin Determined by Spreadsheet.

    50. US 169- Flat Profiles Make Checking Overtopping Critical Used Elevations Calculated by GEOPAK Culvert from Median Centerline & PGL at Lowest Point Near Culvert for Cross Road & Section Line Culverts. Elevations for Drive Overtopping Were Determined & Input by User.

    51. Typical US 169 Computation Tab After Calculations

    52. Typical Data Output File for US 169 Cross Road Culvert

    53. Profile/Section of Culvert All of the Information that Can Presently Developed in GEOPAK Culvert on Profile/Section of Culverts. 6th Tab - Culvert Profile is to be Developed by GEOPAK in the Future.
