This represents the alert coverage of sirens installed on dams. Some approximations have been made by generating buffers with a predefined coverage radius based on the technical specifications of the sirens, while others have employed acoustic propagation models that incorporate factors such as attenuation, sound dispersion, and the influence of topography.

This dataset contains the geographical location of sirens installed on dams, designed to act as an alert system in the event of a dam or dike breach. The installation points have been determined based on acoustic dispersion models and an analysis of flood-prone areas with resident populations, aiming to optimize coverage and ensure immediate notification to the people living in these areas.
