1. A method of enabling hydromodification management to compensate for changes in water runoff characteristics resulting from altered land use, the method comprising:

  • creating parameters of a pre- and post-development continuous hydrologic simulation model of a drainage management area of interest;

    defining pre- and post-development flow duration data based upon the hydrologic simulation;

    defining desired post-development flow duration data resulting from use of flow control;

    creating flow rating data from the defined flow duration data;

    defining the physical parameters of a runoff detention facility having a water outlet with a selectively adjustable opening;

    defining control parameters for controlling the size of the outlet opening on the basis of the created flow rating data and the defined physical parameters;

    programming a controller in communication with the outlet with the control parameters;

    controlling, by the controller, the outlet opening based on the control parameters and thereby providing the flow control;

    actively monitoring characteristics associated with the detention facility over time to define an actual post-development flow duration; and

    comparing the actual post-development flow duration data with the previously defined post-development flow duration data and, if the actual post-development flow duration data differs from the previously defined post-development flow duration data,recalibrating the continuous hydrologic simulation model parameters based upon the actively monitored characteristics,redefining the pre- and post-development flow duration data based upon the recalibrated hydrologic simulation model parameters,recreating the flow rating data from the redefined pre- and post-development flow duration data,redefining the control parameters for controlling the size of the outlet opening on the basis of the recreated flow rating data and the defined physical parameters, andreprogramming the controller with the control parameters.
