Avoidance of Severe Flood Damages In Sudan Using GIS

Abstract

In last year's rainfall affected many parts of Sudan including people by losing their beloved and healthy environment, in which they lived basically their whole life. So we need to find a suitable solution to solve this problem and to avoid severe damages. All previous studies we reviewed presented mathematical theory solutions and did not support or prove any practical solution. The idea of this research is to processing and prepare data of water gauge stations to allow for the calculation of the amount of water and the area which might become affected by floods. We will show that after the right pre-processing of the data of gauge stations we are ready to calculate the amount of flood water. In detail we found out that it is important to know the highest point in the river and the lowest level, in order to use this information for a detailed flood water analysis presenting the areas which are affected.
