I am new to ArcGIS and I am doing a flood map analysis in an estuary. 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. 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?!
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.
Got stuck now so I shall be deeply appreciate some advice or help. Thanks!
