At this stage of the SIMS development, YOU are provided the opportunity to over-ride the hydrology model estimated results of runoff quantities at any nodal point within the hydrology model network(peak flow rate, etc.) and enter, as a parameter, a substitute set of runoff values. These substituted values will remain fixed in the data base unless further modified by YOU, or unless YOU remove the user-specification value option designation from that data base field.
Reasons for over-riding the computed runoff values include:
– Increasing the flow rate to provide additional flood protection
– Changing the flow rate for sensitivity testing purposes
– Changing the flow rate to accommodate supplemental calculations not included in the hydrology model module options
– Other reasons
