Common use of Model Results Clause in Contracts

Model Results. The model was applied to the various design storm events in the current drainage configuration pattern and is identified in the report as preconditions (Pre). Once the Preconditions model results were obtained and verified, modifications were made to the model that would simulate the proposed improvements for re-hydration of the project area. The proposed improvement model runs are identified in the report as Postconditions (Post). WilsonMiller, in order to determine the required surface water elevation, reviewed the historic flow patterns and re-establish the desirable plant communities within the project area. The surface water elevations for the desirable plant communities were established throughout the project area by the project ecologists. Peak stages for the four design events are shown for the selected basin nodes in pre and postconditions in Table 4-1. The locations of the selected basin nodes referenced in the table are shown in Exhibit 3-4. Postcondition for the basin nodes illustrate resulting peak water levels greater than or equal to the Precondition level. The larger storm events that occur less frequently reflect a slight difference in water elevations. The smaller more frequent storm events show greater increases between 0.4 and 0 feet. The model results also illustrated that after a storm had occurred in the preconditions state the peak stage would recover in less than 48 hours. Postcondition results indicate that the peak level, although equal to or slightly higher than preconditions, would remain staged for longer periods of time (240 hours and greater). 100-YEAR 24-HOUR PRE 3.8 4.3 4.7 4.3 2.7 4.0 POST 4.2 4.3 4.7 4.4 2.7 4.0 25-YEAR 24-HOUR PRE 3.5 3.9 4.2 4.0 2.4 3.7 POST 3.7 4.0 4.2 4.0 2.4 3.7 10-YEAR 24-HOUR PRE 3.3 3.7 3.9 3.7 2.2 3.6 POST 3.4 3.8 3.9 3.8 2.2 3.6 5-YEAR 24-HOUR PRE 3.1 3.5 3.7 3.5 2.0 3.4 POST 3.2 3.6 3.7 3.6 2.0 3.4 100-YEAR 24-HOUR PRE 2.9 3.9 4.1 2.7 3.5 1.5 POST 2.9 3.9 4.1 2.7 3.5 1.5 25-YEAR 24-HOUR PRE 2.6 3.6 3.8 2.5 3.2 1.5 POST 2.6 3.6 3.8 2.5 3.2 1.5 10-YEAR 24-HOUR PRE 2.5 3.4 3.6 2.3 3.0 1.5 POST 2.5 3.4 3.6 2.3 3.0 1.5 5-YEAR 24-HOUR PRE 2.3 3.3 3.5 2.2 2.9 1.5 POST 2.3 3.3 3.5 2.2 2.9 1.5 100-YEAR 24-HOUR PRE 1.0 1.8 1.0 POST 1.0 1.8 2.0 25-YEAR 24-HOUR PRE 1.0 1.8 1.0 POST 1.0 1.8 1.7 10-YEAR 24-HOUR PRE 1.0 1.8 1.0 POST 1.0 1.8 1.5 5-YEAR 24-HOUR PRE 1.0 1.8 1.0 Peak flows for the four design events are again illustrated for the selected structure nodes in pre and postconditions.
