LOTUS Spreadsheet Design for Storm Drain Networks

Abstract

The ability to accurately route flows through storm drain networks relies not only on the skill of the engineer, but also on the resources at his disposal. The purpose of this paper is to stress the advantage of using a shell system, in this case LOTUS 123, to perform storm drain designs. Pipe segments are conceptualized as storage elements, distributed or concentrated. The proposed analytical method uses analytical, algebraic relationships derived from linear diffusive wave theory and provides reasonably accurate designs at a very modest computational effort. This procedure is applicable to desktop calculations, but the utilization of the LOTUS environment provides the greater ease and efficiency necessary for routine use.
