Risk flood matrix for urban services in Baghdad city

The hazards of floods in the world were and still vague matters to forecast because it is difficult to predict the type of flood that the city will be exposed to and the amount of damage it will cause if it happens to a city, However, it is very important to understand the level of risk for each case of expected floods (whether the flooding is pluvial flood or dam failure flood), That’s make residents and decision-makers understand how to deal with obscure areas and how to choose land uses and locate them in the appropriate place away from risks and according to urban planning standards, The risk matrix is a new method for planning institutions to study and understand the lands and avoid locating land uses in dangerous lands because it is considered an important tactic in the strategic plans that must be carried out for the lands before embarking on the establishment of projects and urban infrastructure services, The risk matrix includes an inventory of the expected risks that these lands may pass through on the one hand and the type of uses on the other hand, to study the potential of exposure of these lands and uses to the expected risk, This paper discusses the impact of the hypothetical collapse of the Mosul Dam on some of the infrastructure urban services of the city of Baghdad, for example (main water plants, main power stations, sewage treatment plants, oil refinery, Baghdad International Airport) and in two cases (collapse in the case of the level of the lake of the dam 319 m and The collapse in the case of the level of the lake of the dam 335 m), The result is two risk matrices that show three risk levels for each service (low risk, medium risk, high risk) and for two cases of dam lake level.
