Developing Wet Weather Events from Long-Term Historical Rainfall Data
Abstract:Wet weather events are used to analyze the capacity and performance of sanitary sewer collection systems. Many different types of wet weather events are used in the industry today including historical rainfall events, design storms, IDF curves and long-term continuous rainfall simulation. Determining which type of wet weather event to use for evaluating a sanitary sewer collection system involves many issues and each has it's advantages and disadvantages. This paper will focus on developing wet weather events from long-term historical rainfall data. A case study using the National Weather Service Oakland Airport rain gauge will illustrate the methodology involved in developing wet weather events from long-term historical rainfall data, and compare the results with other rainfall development methods.
