It is worth noting the increase in runtime, by halving the cell size by a factor of 2, we have four times as many cells (each 5m x 5m cell is now four 2.5m x 2.5m cells), we also needed to reduce the timestep, as the Courant number is directly related to cell size (refer to the TUFLOW manual) this would normally be reduced by a factor 2 as well. This translates to an approximate increase in runtime of 8 (four times the number of cells and half the timestep). Choosing an appropriate cell size that allows representation of the hydraulics whilst resulting in realistic run times is an important part of the modelling process. With some planning you should be able to avoid a model that requires excessive run times!<br>
