Watershed

Watershed is an educational sandbox for real terrain. Draw an area anywhere on Earth, pick a storm, and watch real elevation data fill its valleys, carve rivers and run to the sea, live on your graphics card. Then drain the oceans back to the Ice Age, roll the atlas back to the Bronze Age, and send a caravan across what remains.WeatherSix storm presets with their real order of magnitude, from a desert cloudburst to a monsoon week, or set every number yourself. Turn the rain up until the valley floors become lakes, then ease it off and watch them drain. Cloud shadows, rain and lightning play over readable ground, and a procedural soundscape follows the water.OceanLower or raise the world sea level from 500 m below today to 80 m above, on real bathymetry. The Persian Gulf drains into a river valley, Dover joins Calais, deltas drown.TimeAn
