The goal of this lab was to learn to use ArcScene to create a flood inundation model for the Eau Claire area.
METHODS
First, using ArcMap, breaklines were created and enforced for water bodies. A DTM image with flattened water was then created. These were brought into ArcScene. An animation was created by raising the water level by 5 feet per frame to simulate the rise in water level due to flooding. The model had to be adjusted using breaklines to ensure that the flooding begins from the river.
RESULTS
The final animation that was created is shown below.
SOURCES
Data obtained from Cyril Wilson for use in 358 LiDAR course.
