English/Metric Units The program is capable of working in either English or Metric units. It does not do so by converting input and output, it uses dual sets of formulas where necessary just as the HEC 22 manual recommends.
Libraries - The program creates and maintains a separate database to use as a library for Inlets, streets, and drainage areas. The appropriate library is automatically referenced, and can be used to instantly insert needed values. A tremendous timesaver!
Check Input Values a feature is in included that checks the values you have input against a reasonable range for that item. This feature can perform a check on one location or the entire project.
Messages about answers the program doesnt leave you wondering about the answers. Several conditions are checked as the calculations are made, and if necessary a message is entered in the database for that location. Messages such as "Exceeded the maximum allowable ponding depth" and "The depth exceeded the right curb height" assist the Engineer in evaluating his design.
Handy "Information Buttons" rather than wandering through a help system, "Help buttons" are available with each input value to quickly answer the most common questions about input.
Simple illustrations, clearly labeled with the input values needed take the guesswork out of data entry.
Roll, vertical, and wedge type curbs are all calculated. The curb sections included are not the oversimplified vertical curb sections found in the government manuals. They allow for a depressed curb section and for a batter on the face of vertical curb.
Several Street Sections
Several Street Sections including Normal street sections (single cross slope), broken back sections (two cross slopes), full width street sections (single cross slope and gutter on each side of the street), and inverted crown streets are all accommodated.
Trial and Error/ "What if? " feature - The calculations section includes a feature that lets you vary the input and see the results immediately - without having to print a report. This is an excellent way to fine-tune your design quickly and efficiently.
Three types of reports are available a summary report that gives an overview of the total system performance, a detailed report that provides one page (or more) per inlet, showing all the important design answers, and a "Tracking" report that includes the intermediate and final answers in sufficient detail to allow the Engineer to track the answer by hand, if there is any question about the calculations.
