Simulating Flood Control in Progress Village, Florida Using Storm Water Management Model (SWMM)

Flooding is a natural event caused by heavy rains, melting snow, high tides, and anthropogenic impacts such as channel clogging, improper land use, and deforestation. In this study, the strategies for controlling flooding seek to establish flood prevention systems by implementing grey infrastructure and green infrastructure practices. The main objective of this thesis is to analyze the study area, Progress Village Neighborhood in Delaney Creek Watershed, regarding flood risk and flood mitigation techniques. The analysis was performed using EPA SWMM 5.1 and Arcmap 10.7.1. The study used design storms,10-years 24 hours and 25-years 24 hours, to analyze flood risk in Progress Village. After running the SWMM for the Delaney Creek Watershed, the flood maps were generated based on existing conditions for defined design storms. The generated maps revealed flooding areas from the 10-year and 25-year 24-hour design storms. A comparative analysis was run to determine the amount of inundation for each scenario to evaluate each proposed solution\u27s effectiveness. There are three simulation scenarios: LID scenario based on infiltration (infiltration trench and bio-retention cells), LID scenario based on storage (rain barrels), traditional structural practices (installing retention pond and pipelines) and existing conditions is used as a baseline in EPA SWMM. The degree of effectiveness based on inundated area reduction is 7% for implementing Infiltration trench and Bio-retention Cells and 1% for implementing Rain Barrels. The effectiveness of the implementation of traditional infrastructure is 0.66%. The model\u27s results indicate that the traditional infrastructure design method would not address all of the study regions\u27 floodplain problems, and low-impact development alternatives are more effective at flood remediation
