Lasindu Kotavilaarachchi, Divisional Irrigation Engineer, describes how mobile weather stations are being utilized to mitigate flood damage within the Nachchaduwa Reservoir and the Malwathu Oya River Basin of Sri Lanka.
According to his experience, these devices help capture essential rainfall data over long periods, which is critical for flood modeling and analysis. The system is very cost-effective and easily scalable, so planners can establish a robust database. By deploying these stations in downstream cultivation areas, irrigation authorities can accurately monitor rainfall, allowing for better water management and sustainability.
Another added benefit is their educational potential. The system is simple enough that it can be taught to local farmers’ children, encouraging interest in electronics and enabling community-led improvements to the system.
