Such a plan is aimed at raising the preparedness levels and making response activities by the local authorities’ and the general public more efficient especially during a flash flood3. Such plans integrate the use of technological variables of weather forecasting and GIS-based system for data management processing. This research is aimed at contributing to the development of integrating flash flood management plan in some flood prone areas.
The most important things about planning for a flash flood is warning the general public and the response to the floods ensuring that loss of lives and property is minimal. Warnings about flash floods are transmitted by the meteorological departments and the hydrological services in various countries. In all flood management plans, organization and dissemination of information to warn the people is the most important thing4.
The first element of a flashflood management strategy is finding out about all those who are at risk and whatever else is at risk. Risk is determined through assessing by establishing the hazards, the levels of exposure and the vulnerability of the people. The hazard entails the magnitude and the probability of occurrence of the flood5. This information can be given in form of maps which outline the borders of the areas at risk and their expected velocity6. Exposure on the other hand is the information of all those who are in danger as well as all what is in harms way. Vulnerability entails the expected losses which are looked at in terms of the geophysical, economic and the societal attributes of a given region. By establishing all the three elements enables those involved in the flood management to adopt the most effective strategies, be it to deal with engineering problems or dealing with the social challenges7. To establish the extent of the three elements, a risk analysis must be conducted.
