=Introduction=
TUFLOW can directly read elevation data from a Digital Elevation Model (DEM). One of the formats recognised is the binary .flt format. This is a widely used format and is mush faster to read / write than the ESRI ASCII Grid (.asc). The instructions below outline the process for exporting from a raster layer in ArcMap to a ESRI ASCII grid.<br>
<br>
TUFLOW can also read .flt format data for setting a number of model parameters including, initial water level (Read GRID IWL == ), Soil Type (Read Grid Soil == ), roughness (Read Grid CnM == ), storage reduction factor (Read Grid SRF == ).
