Create Water Element

[nurfaizfy19]

Hello, sorry for my bad english

I want to make water elements in the gutter like in the screenshot, I use the function below

function setWater()
	setWaterLevel(10)
end
addEventHandler("onResourceStart", root, setWater)

the function above changes all elements of water including the sea, so buildings near the sea will be submerged in water. how to make the water level only in the gutter?

Thanks
