Buffalo Bayou Watershed Near Katy Flood Analysis

Abstract

Buffalo Bayou, originating near Katy, Texas, is a vital watercourse within the Houston metropolitan area, traversing diverse urban, suburban, and rural landscapes. This paper investigates the flood mechanisms impacting the Buffalo Bayou watershed, focusing on significant flood events and various flood mitigation methods. Key historical floods, such as those caused by Tropical Storm Allison (2001), the Memorial Day Flood (2015), the Tax Day Flood (2016), and Hurricane Harvey (2017), underscore the region’s vulnerability to intense rainfall and storm systems. By examining a 20-year period of daily streamflow and climate data, this study employs the bucket model to simulate long-term discharge and predict flood occurrences. The results highlight the critical need for effective flood mitigation strategies, including the use of reservoirs, green infrastructure, and infrastructure improvements. The study aims to enhance flood management practices and community resilience within the Buffalo Bayou watershed, offering insights into the dynamic interplay between natural hydrological processes and human interventions.
