Increase water leavel dynamiclly

I’m new to Unreal Engine and currently working on a project that simulates the consequences of climate change. In my project, I have created a city with various buildings, and I want to implement a feature where users can click a button, and when clicked, the water level dynamically increases to simulate flooding as a consequence of climate change.

Since I’m new to Unreal Engine, could someone guide me on how to dynamically increase the water level in Unreal Engine when a button is clicked? I’m looking for suggestions or tips on the best approach to achieve this effect within my project. Any help or insights would be greatly appreciated!
