Hi! When calculating the roughness coefficient it says to refer to page 33 of the Flood Simulation manual. I can’t seem to download it (though if I can find it I have someone that can help with the Japanese!) I have a few questions: 1) for Theta, the proportion of landuse – should that be a whole number or decimal or percent? And when solving n, it seems to solve for n^2. Should we then take the square root of that number to input into the model or do they consider n^2 the roughness value?
