Distance & Area Calculator Calculate distance and area for selected points on the map... Find Watershed Boundary (500m) Click on a location on the map, and automatically find the watershed boundary... Raindrop Flow Tracker (500m) Click on a location on the map, and find the path for a rain drop flowing on the landscape... Flood Risk Calculator Return period corresponds to the probability of the annual maximum river discharge exceeding a certain (given) value. For example, return period of 100 yrs corresponds to the probability of 1% of discharge exceeding that value, and return period of 10 yrs corresponds to 10% chance of flow exceeding a different (lower) value in a given year.
