Using ArcGIS Pro to visualise layers relating to flood risk within a Multi Criteria Evaluation approch in Offaly, Ireland. Slope was the most visually interesting data metric. As a key determinant of filtration, slope greatly influences the intensity of runoff in a particular area. This constraint visualised below aims to incorporate the factor of slope between 0 and 15 to allow for the varying effects which flatter terrain can have on the fluvial process. This was carried out by using the following formula within the raster calculator to create a new raster with values only below 15 degrees.Con(("Offaly_Slope_DTM" < 0) | ("Offaly_Slope_DTM" >= 15), "Offaly_Slope_DTM")
