Waves on landscape
Hello everyone. It's time to make a serious face and start writing an answer. I'm really "teapot" in using ue4 or other programs, so biggest part of my qestions are pretty easy for you.

Traditionaly, to simulate water pouring out the side, you would use particle effects to emulate the gush of water.
Ocean waves can be made by panning height and normal maps accross a tesselateds plane, this is a pretty common, and simple aproach. Alternatively, you can creat mathBased "gerstner waves". Another aproach, would be to use a spritesheets/flip book. You can render a tiling flip book animation of an ocean simulation in a program like houdini, and use that in a UE4 material.
Limitations in the engine are likely because it has to render every frame in real time, so you have to take a different aproach ti some things than you would in Maya for example, where you can spend hours rendering each frame if you want. If you want fluid dynamics i think there is a plugin for that. If you want to make your own you might consider an approachc similar to meta balls or octree. It's not native part of the engine though. study hiw dynamic fluid has been done in other real time applications.
