Objects blend with landscape on "far" camera

So my problem is very simple, i’ve made a landscape and i made some kind of a valley to place a river there, than i filled the valley with box brush to create “water” plane on which i will put water material, however when i move my camera faraway from the box it simply blends or blurs with the landscape. My question is, how to fix it?

Nevermind, found a solution, you need to set in Landscape on the level a parameter called LODdistancefactor to 0.1
