The main objective of this book is to draw a comprehensive and integrated picture of the main components of water resources in the Sudan, noting the growing and competing demands for these finite recourses. This was considered the right time to undertake such a compilation; before it becomes too late to avoid future mistakes in water allocations. It comes also at the eve of planning the Sudan’s responses to 2030 Sustainable Development Goals (SDGs) in which water resources play a significant role. 

The structure of the publication includes the following three sections:
•    The first section of the publication focuses on the elements of the water resources themselves with four chapters consecutively on: “Water and Climate”, “Water and Hydrology (Surface and Groundwater)”, “Water Related Disaster (Floods and Droughts)” and “Rainwater Harvesting in Sudan”.
•    The second section of the publication focuses on water applications with nine chapters consecutively on: “Water and Agricultures Nexus”, “Water and Energy Nexus”, “Water and Human Needs and Livestock requirements ”, “Water for Industry”, “Water and Transport”, “Water and Environment Nexus in the Sudan”, “Water for Recreation”, “Water, Health and Sanitation Nexus” and “Water and Culture”.
•    The third section of the publication focuses on water management issues expressed in eleven chapters on: “IWRM in Sudan”, “Decision Support Systems for Water Resources Development and Management”, “Water Governance”, “Water Capacity Development”, “Modeling Techniques”, “Water Information System (WIS)”, “Socio-economic Characteristics and Sanitation Facilities in Sudan”, “Hydro-economic Aspects”, “Enhanced Knowledge-base and Capacity for Hydro-Cooperation within the Nile Basin”, “Water Laws and Regulations in Sudan”, and “Sudan and International Water Laws”.

Project’s Objective:

The main objective of this project is to provide a solid baseline data for flood risk management of Al Gash River using:
   - RTK-GPS,
   -   Remote sensing, and
   -   GIS.

TOR:

- conduct  RTK Survey for the longitudinal section of the Gash River {27 KM) at 20 cross-sections.
- Develop contour map for the flash flood affected areas in Kasalah city about {70 km2) with a cross-section every 1 km interval.
- Provide Satellite image maps for the hotspot area and develop GIS Maps using land sat and MOlDS sat data.
- Prepare frequency analysis of historical water levels and flows at the main station (Bridge station) and Geira station.

- Develop flood hazard maps for various return periods {25yr, 50yr, and 100yr).
- Conduct assessment of affected population (current status), identify risk areas and zones  for future planning, and develop flood risk maps.
-    Propose remedial measures for flash flood risk mitigation in Kasalah.
- Prepare technical report documenting and outlining the main activities of the development of Flash Flood  Hazard and Risk Maps for the Gash        River, Kasalah, Sudan.

Methodology:

- Site visit.
- Review of previous works.
- Collection of existing data.
- Building GIS from the existing data.
- Field work.
- Field work data verification.
- Office work for data processing & analysis.
- GIS for Kassala City.
- Generate the required outputs for the flood analysis.
