The main object of this diploma work thesis is about how computer programs can be a tool to use for work on stormwater investigations. The advantage of using a computer program compared with calculations made by hand is evaluated and discussed. The computer programs that have been used for studies and a sequence of testing of the possibilities are Autodesks Storm and Sanitary Analysis and DHIs Mike Urban. Focus on sustainable development now permeates the building industry. As a result stormwater investigations have been conducted in an increasing extent the recent years. Stormwater is water produced due to precipitation, such as rain and snowmelt. Stormwater investigations normally contain descriptions of existing land use, planned land use and suggestions of measures and technical solutions for the future disposal of stormwater. The initial part of the thesis consisted of literature studies on stormwater and stormwater investigations to understand the science. Further literature studies where related to hydraulic and hydrologic modeling. An analysis of the interest and way of applying these methods among municipalities and sewer companies where performed. Literature studies and situation analysis formed the basis for the design of the evaluation methodology where a number of key points were chosen and followed-up for both programs. The results of the thesis shows that there is a big advantage in using computer simulations for accurate mapping of the pipe networks provided that you also have the means to calibrate the hydrologic and hydraulic models. For less accurate analyzes, computer programs may be seen as a tool for data management.
