SCALGO Live Global shows: 1) Water Flow: The terrain topography determines how surface water is transported to the ocean. Explore how water flows on the surface and forms flow networks, interactively choosing network detail. 2) Sea-Level Rise: The terrain contains barriers to rising sea water, once water rises above these barriers there is a risk of flooding. Interactively select any possible sea level rise and see the effects. 3) Watersheds: A point on the terrain surface can potentially receive surface water from a very large upstream area.
