SYNOPSIS

Development and Application of a Software for the Urban Stormwater Management Manual for Malaysia (MSMA)

The Department of Irrigation and Drainage has released the second edition of MSMA (Manual Saliran Mesra Alam Malaysia or Urban Stormwater Management Manual) in 2011. Like its predecessor, this publication is heavy on computational methods and design procedures. The topics covered in MSMA include computational methods like design storms and temporal patterns, computation of peak design discharge and hydrograph like Rational Method and Time-Area Method, and design procedures on On-Site Detention (OSD), detention basins, sediment basins, culverts and rainwater harvesting.

Most engineers perform drainage computation and design using a calculator or spreadsheet. This approach is laborious and time consuming.
This talk is about the development of a software for MSMA computation. The software consists of the following modules: (1) design storm, (2) temporal patterns, (3) Rational Method, (4) Time-Area Method, (5) OSD design, (6) detention basin design and (7) culvert design.

The software allows the computation of design storm by simply clicking on a map of 135 rainfall stations in Peninsular Malaysia. The software also allows the computation of design storm in Sarawak based on a map of Sarawak rainfall stations.

The software is flexible as it allows the engineer to pick and choose the modules needed. For example, for design storm computation, you can select only Module (1). To compute design discharge using Rational Method, you select Module (1) and (3). To compute design hydrograph using the Time-Area Method, you select Module (1), (2) and (4). To design a detention basin using Time-Area Method, you select Module (1), (2), (4) and (6). For culvert design using Rational Method, you select Module (1), (3) and (7). Participants of the talk will get a free copy of the lite version of the software with unlimited usage if they bring in their pc.
