AQUAS-Lite, Problems with water disappearing when zooming-out.

Hi,
I'm greenhorn when it comes to unity and game developing, but I want to create a grand-strategy game, for terrain creating I'm using NASA World height map and Barymetric map of the oceans and seas. I know it'll be hard though but I really enjoy it.

The problem is that when I'm zooming out the water is beggining to "disappear" where it touches the coastlines (img below). I need to fix it so the world will be still looking good even when the camera fov covers whole EurAsia and part of africa.

(The terrain is flipped vertically in relation to the real world, but on the stage of playing with creation and looking for the best solution it is not important)

So this is how the test world looks without water:
1)


Heightmap I used for generating the world with oceans depths and land height (I've combined two heightmaps in GIMP)

It is 4097x4097 Heightmap which I used to create 2048x2048 terrain with 35 overall height.

And this is how it looks like with water added to terrain, I've underlined the distruptions which appear when I'm zooming out:



This is how it looks when I zoomed out really far:


I was trying to manipulate various variables of material and water plane in unity but nothing seems to work.
Anyone had a similar problem and solved it?

Any help will be aprecieated.
Thanks in advance
