Provide the Risk Assessment for Testing and Commissioning of Drainage System.
Drainage management is one of the most important issues that the governments and managers face today. In recent years, due to climate change, old storm water drainage systems as well as the mismanagement of these infrastructures, considerable damages have occurred in major cities around the world. One of the most practical methods to manage these complex urban systems is using risk assessment techniques to be able to take the uncertainties in design and operation into account. In this paper, a framework for comprehensive risk assessment of water drainage systems is presented. This framework consists of three main parts.
Determination of the probability of flooding using the hydraulic and hydrologic modeling.
calculation of consequences as a function of vulnerability and damage caused by flooding.
The risk estimation regarding the probability and consequence parameters.
For the first stage, Autodesk SSA model was used to simulate the existing drainage system and the critical points and channels are identified by considering the different hydrological return periods. In the second stage, by using the capabilities of GIS and definition of economic, social and technical criteria, consequence parameter is estimated based on spatial decision making approach
