Impacts Of Climate, Land Cover And Hydrologic Changes On Stormwater Runoff In Central Florida, Mohammad S. Islam
FIU Electronic Theses and Dissertations
Changes in climate and land use/cover can cause great impacts on the hydrologic processes, especially on stormwater runoff generation. Considering the Shingle Creek Basin in Central Florida as an example of complex inland urban-natural basins, we quantified reference sensitivities of stormwater runoff to plausible scenarios of climatic, land use/cover and hydrologic changes by developing a dynamic rainfall-runoff model with the EPA Storm Water Management Model (SWMM 5.1). Potential storm runoff in the coupled urban-natural basin exhibited high and notably different seasonal sensitivities to rainfall. The total basin runoff was highly sensitive to the basin imperviousness, while showing moderate to low …

Long-Term Trends In Magnitude And Frequency Of Extreme Rainfall Events In Florida, Tasnuva Mahjabin

This study computed trends in extreme precipitation events of Florida for 1950-2010. Hourly aggregated rainfall data from 24 stations of the National Climatic Data Centre were analyzed to derive time-series of extreme rainfalls for 12 durations, ranging from 1 hour to 7 day. Non-parametric Mann-Kendall test and Theil-Sen Approach were applied to detect the significance of trends in annual maximum rainfalls, number of above threshold events and average magnitude of above threshold events for four common analysis periods. Trend Free Pre-Whitening (TFPW) approach was applied to remove the serial correlations and bootstrap resampling approach was used to detect the field …
