A quick flood screening for a town or a short stretch of river. The model downloads OpenStreetMap buildings, roads and rivers for your study area, reads the river level from your DTM along the river lines, maps all land at or below that level plus 1, 2, 3, 4 and 5 m across the whole study area, and extracts the buildings and roads touching each zone. It also adds each building's mean surface (DSM) elevation and makes a slope layer. The offsets sit in five raster calculator steps named Flood1 to Flood5, so you can change them. It is a bathtub screening, not a hydraulic flood model: it ignores rainfall, flow, timing and defences, and its zones are not the Environment Agency's Flood Zones.
Eight Bozmaps QGIS models in one zip: flood, landslide, wildfire, NDVI, NDVI change detection, land surface temperature, OSM map generator and vegetation vulnerability.
Screens how far inland a tsunami of a height you choose could reach, from a DEM, a coastline and land use roughness, using the published Berryman height-loss method.
Zone of Theoretical Visibility for a proposed wind turbine, mast or tall building, with visible area by distance band and the buildings that can see it.
