This paper discusses the use of Remote Sensing technology and Geographic Information Systems that help in real-time monitoring, early warning, and quick damage assessment of Nile flood disasters. Change detection techniques played a significant role in detecting and interpreting the changes that took place in the affected places, having the ability to determine the disaster volume. Showing where concentrating of the water areas, with the distribution of their line, is considered an essential demand in reaching the most affected areas even if it has less water concentration. (DEM) is considered to be the most effective means to estimate flood depth from remotely sensed data. Reaching a flood stream feature is the goal gained to achieve a good understating of the flood manner, which is fulfilled by processing a hydrological map with its slope and aspect, also determining the flood direction and accumulation to have a stream order map reaching the desired flood stream map.
The obtained results considered crucial information for decision-makers for future effective flash floods hazard mitigation, assessment management, planning, and sustainable development.
