• Fixed an issue in Storm and Sanitary Analysis so the inlet calculations during storm routing now use the same calculation methods as the Curb & Gutter Inlet Calculator.
• Fixed an issue in which Storm and Sanitary Analysis was not adding the triangular portions of a trapezoidal weir so the results were the same as a rectangular weir. Storm and Sanitary Analysis is now using the formula in Table 8.1 in the Storm and Sanitary Analysis User's Guide for trapezoidal weirs and reducing the length of the rectangular portion of the weir if contraction is specified.
