Flooding events: permanent vs temporary
For a permanent water level change through time, animate the Lake Elevation. Surrounding Beach will rise with it.
For a temporary flooding event you want the Beach foliage to stay put while the water rises. Set the Lake Reference Elevation at the established level and animate the Lake Elevation. The beach and foliage still stay in place while the water rises.
Lake edge renders blocky

Usually a Resolution problem.
WCS renders a vector effect using the Component's Resolution
value. If the value is too high relative to curves in the vector,
curves become box corners. There are few solutions.
While this is not realistic, there may be times when you want to do it. Drive the Added Roughness parameter (Water page, Waves tab) with a georeferenced image texture. The texture should be a greyscale ramp where black represents the lowest lake elevation and white represents the highest lake elevation.
