Big Bend Master Drainage Plan

A hydraulic 1D/2D computer model was created using MIKE-FLOOD, MIKE-URBAN and MIKE-21 FM to represent the storm system for the study area. MIKE-21 FM was used to model the major system (overland flow) in 2D. The 1D model was utilized to model components such as small and medium natural waterways, pipes, ditches, culverts, stormwater ponds, pump stations and flow control structures. The 2D model, on the other hand, contains all major topographic features, such as roads within the street network and adjacent properties, railways, channels and dikes so that overland flooding and surface conveyance will represent the current topographic condition. The benefit of this approach is that it provides the City with information on where the uncollected or surcharged water goes when it flows through the project area.
