This focused on my experience as an Engineer in the Mahaweli River basin. Simultaneously, Floods & droughts are the major problems in this basin, I tried to use the upper reservoirs to control these disasters by finding the reasons and ways to manage these difficulties by using gathered knowledge at ICHARM. This helps me to understand the conflict among stakeholders, and find the reasons and solutions for efficient water management in the system, by developing a physical model based on policies.

To support decision-makers in flood disaster management, a real-time flood monitoring system was established in the Niger and Volta basins under the Water disaster platform to enhance climate resilience in Africa (WADiRE-Africa). The system utilized real-time satellite rainfall data to bridge the gap between data scarcity and inaccessibility and a hydrological model to simulate the inundation extents at basin and hotspot scales. Presently, the prototype system is under testing in both basins.

Early flash floods result from the abundant precipitation frequently lead to significant losses of agriculture in the north-eastern region of Bangladesh. Allocating necessary storage to provide spaces for excess water can save the crop. This study calculates the necessary storage with a new method: Flood duration curve (FDC); estimates water storage capacity by using satellite-based citizen science haor volume estimation technique and finally, investigates an alternate solution of the problem.

The study provides valuable insights into the use of cutting-edge technologies for real-time extreme flow modelling and disaster risk reduction strategies in data-scarce regions. The methodology presented here improved forecasting lead time and accuracy of real-time satellite precipitations. This highlights the practical implications of public domain datasets and models for informed decision-making. The study can complement informed decision-making for flood preparedness in transboundary basins.
