Development of a GIS-based Software System for Flooding Water Management

Abstract

Due to the great change of Global weather, rain falls and floods have caused real disasters in many of the world countries.Sudan was one of the countries that had been affected by excessive rain fall and flooding. In the year 2007, heavy rains had fallen in different parts of our country. Khartoum State had the lion share of rain water and flood. Which had brought real harm to the population of Khartoum State. To participate in solving the rainy season problem ,this research have been accomplished to concentrate on the development of a GIS-based software system to obtain the information required for helping the planners in the Ministry of Physical Planning and Public Utilities (MPPPU) for drainage of rain and flood waters management in Khartoum State . Omdurman City (Elthawrt) was undertaken as a case study to meet the requirement of this research. This Geographic Information System (GIS)-based system consists of two types of data non-spatial data was collected either via interviews with some employees in different departments or by using the existing documents and spatial data was collected using the information existing in the manual maps . Four softwares have been used to fulfill the analysis, design and implementation of the Geodatabase system these tools are Unified Modeling Language (UML) tool which is used for the analysis and design of the database, MicroSoft (MS) Access is used in the project as backend database , Visual Basic is used as a front-end or interface for creating forms so as to save the data in the backend database (MS Access) and ArcGIS9.0 is used for representing spatial information . This Geodatabase system has to be capable of meeting the requirements of the manual maps and solving its disadvantages such as search and update problems.
