Flood monitoring and management system

A method comprising:

• accessing, by one or more processors of a flood analysis system, weather information for a geographical region that is divided into cells;
• generating, by the one or more processors of the flood analysis system utilizing a hydrological model, runoff data based on the weather information, the runoff data including a predicted amount of free-running water on a surface of each cell of the geographical region for a plurality of times;
• generating, by the one or more processors of the flood analysis system, a prediction of inflow and outflow of water between cells for the plurality of times;
• calculating, for a plurality of sub-cells of each cell in the geographical region, a predicted water depth, for the plurality of times, in each sub-cell based on the prediction of the inflow and outflow between cells and a hydraulic model;
• generating, by the one or more processors of the flood analysis system, a flood inundation map showing the predicted water depth at each sub-cell in the geographical region at one of the times from the plurality of times;
• causing, by the one or more processors of the flood analysis system, presentation of the flood inundation map in a user interface of a display device;
• tracking asset information for assets in the geographical region, the asset information including type of asset, building material, year of construction, and asset location;
• calculating a number of assets in the geographical region that are impacted by flooding based on identification of assets impacted by flooding;
• estimating damages for the assets in the geographical region due to the flooding based on identification of assets impacted by flooding, the asset information, the predicted water depth at each cell and flooding information for the assets in the geographical region;
• tracking a number of people in the geographical region affected by the flooding based on number of people affected in each block;
• and
• presenting, in the user interface, the number of assets impacted by flooding, the estimated damages for the assets, and the number of people affected by the flooding in the geographical region.
