I've already created a DEM using the Lidar data. I also have a shape file of some coastal defence such as flood walls along the estuary.&nbsp; The lidar data should be unfiltered and already picked up the elevation of the flood walls. Do I need to incorporate the coastal defence as breaklines and how I can do that?! I want to simulate a rise in the water levels. Can I generate a video clip showing the extent of the water surface with the increase in water levels?!</SPAN><BR /><BR /><SPAN>I dont know how to generate a view of the water surface although I can create a view showing elevations, say less than or greater than 2m mpD, by simply re-classifying the symbologies into 2 classes.</SPAN><BR /><BR /><SPAN>Got stuck now so I shall be deeply appreciate some advice or help. Thanks!</SPAN></BODY></HTML> Thu, 23 Jun 2011 11:14:03 GMT SamKwan 2011-06-23T11:14:03Z flood map with coastal defence https://community.esri.com/t5/water-resources-questions/flood-map-with-coastal-defence/m-p/312750#M1518 <HTML><HEAD></HEAD><BODY><SPAN>I am new to ArcGIS and I am doing a flood map analysis in an estuary.
