AltBlock - Software para determinação de Chuvas de Projeto

Abstract

A design storm can be defined as a precipitation pattern used to determine indirectly the design flood, which is important data in many hydrologic design projects. Due to the difficulty to obtain historical data on precipitation, it has become common to construct design storms using general characteristics of precipitation in the surrounding region, represented by intensity-duration-frequency (IDF) relationships. In addition, it’s also necessary to specify the design return period, storm duration, and temporal distribution. For this purpose, is used the Alternating Block Method. In view of software development applied to hydrology and to make it more practical using this Alternating Block Method, this article intended to develop the AltBlock, a software able to calculate design storms automatically. Using Visual Studio .NET and the programming language Visual Studio .NET it was sought to build a graphical user-friendly interface. The AltBlock is applicable to any location and it’s useful for educational uses, engineering projects, and hydrological studies
