Users who are not familiar with NRCS hydrologic procedures should refer to the appropriate chapters for background information and the details of procedural techniques. Appendix C of the WinTR-55 User Guide (part of the install package) contains a list of the Part 630 chapters and their subjects.

Part 630 of the Natural Resources Conservation Service (NRCS) National Engineering Handbook provides detailed information on NRCS hydrology and is the technical reference for this document.

This user guide covers the procedures used in and the operation of the WinTR-55 computer program. Computer availability eliminated the need for WinTR-55 Guide methods, thus the guide portions (graphs and tables) of the user document have been eliminated. The availability and technical capabilities of the personal computer have significantly changed the philosophy of problem-solving for the engineer.

As you level up, you unlock new abilities and vehicle customisations. You start small, using your vehicle to transport goods for other companies. The current changes include: upgrade the source code to Visual Basic, change the philosophy of data input, develop a Windows interface and output post- processor, enhance the hydrograph-generation capability of the software and flood route hydrographs through stream reaches and reservoirs. SCS Software provides a realistic experience in this truck simulator game. A WinTR-55 work group was formed in the spring of 1998 to modernize and revise the Technical Release and the computer software.
