WMS:Assigning an Equation
The Basin Time Computation dialog allows selecting from one of several pre-defined equations. The Equation drop-down box lists the available methods for computing lag time or time concentration and is controlled by setting the computation type combo box to the desired setting. Once an equation has been selected, the Instructions / Results window will identify any variables with zero values and instruct to define values for them. Variables are assigned values by selecting the variable from the Variables text window and then assigning a value to it in the edit box to the right. Once all variables are defined the Instructions / Results window will display the computed lag time or time of concentration.
