Really big thanks to all who will help me!

On the AUM Resources page under Tutorials you'll find a intro to shader programming. You can also purchase books such as the ShaderX series.

In the mtlFX.wdl are two water shaders, also here on the shader forum are many water shaders and in the last AUM issues are also many water shaders. But to learn how they are done the best book is the ShaderX book.

Where can find that book?

http://www.amazon.com

Has a few of them (if not all). Just make sure you've got the right one. There not all about shaders

Bad idea! In this country from who i come peoples arent so rich to buy even books for 20- 30 dollars!

And that can be when effects fails? Some of them shows like black or white terrain!

No offence but you asked where you could buy them. I simply pointed at a point where you could do just that. I am of course not aware of your state of wealth. But hey 3dgs costs even more so you could cough up $20 for a book right. Or just search the internet. Enough tutorials about HLSL :

This one is openGL, but you could use it for the required technique

or look at NVidia's ocean shader on how they did it.
