Sex trafficking is one type of human trafficking, which involves scenarios where individuals are not paid and are forced to engage in forced sex, forced prostitution, and sexual slavery. Online advertising is increasingly used by traffickers as an anonymous and efficient method to exploit victims. Large sporting events have been linked to increases in sex trafficking, although there is limited empirical evidence to support this claim. The goal of this study is to answer the following question: What is the relationship between Super Bowls and potential online sex trafficking? Using time series Poisson analysis of secondary data on online sexual service advertisements in Florida during the 2020 and 2021 Super Bowls, which took place in Miami and Tampa, Florida, respectively, the result indicates an increase in online advertisements that exhibit indicators of sex trafficking during the two Super Bowls. The paper concludes by providing recommendations for federal, state, and local law enforcement for improving sex trafficking responses during large sporting events and outlines a future research agenda on the relationship between large sporting events and sex trafficking.

[Display omitted] • The trends of surface runoff and flood area changes were different. • Rainfall change is the dominant driver compared with land use change. • There are coupled effects from rainfall and land use changes on both surface runoff and flood area. • The easily flooded areas would experience negative coupled effects under future rainfall and land use conditions. • The areas with inadequate drainage and low elevation variation would be of high probability to suffer flooding issues. Future rainfall and land use are two important factors for flood management since they both directly and indirectly affect the functionality and performance of urban stormwater drainage infrastructures. Although some studies have already examined the coupled effects of future rainfall and land use conditions, they have not concluded how such effects on both surface runoff and flood areas would change with regional surface elevation variation and infrastructure conditions. This paper analyzed the coupled effects of future rainfall and land use on urban drainage systems in terms of surface runoff quantity and flood area changes using EPA SWMM. Future downscaled and bias-corrected precipitation projections for 2040–2060 and 2080–2099 from "Downscaled CMIP3 and CMIP5 Climate and Hydrology Projections" Archive and future land use for 2050 s and 2090 s from EPA ICLUS project were used for the City of Tampa in Florida (USA). It was shown that potential runoff volume and flood area changes ranged from −40% to 160%, and −40% to 400% due to rainfall change, while potential changes induced by land use change ranged from 0% to 3.5%, and 0% to 18% respectively. Additionally, this study examined the coupled effects of future rainfall and land use changes on flood area variations, considering the capacity of drainage infrastructure and elevation variation of study site. Results showed that flood area variations are not solely influenced by runoff quantity changes due to the two external drivers, but also by other factors. Specifically, in low-relief areas with inadequate drainage infrastructure and less elevation variation, these two drivers have no additive effects on the percentage of flood area changes. In contrast, in areas with adequate drainage infrastructure and greater surface elevation variation, there are additive effects from rainfall and land use changes on flood area expansions. These findings have important implications for stakeholders involved in city planning and flooding control, particularly for urban areas facing future precipitation and urbanization challenges.
