I advise using this tool to make sure surrounding ground is not below the river height otherwise water may 'leak' out.ĥ. Correct the terrain: Use the 'Soften Terrain' landscaping tool to smooth out any sections that may have appeared after aligning the slope. Smooth the slope: Use the Move It 'Align Slope' tool to ensure that all the river nodes are gradually descending.Ĥ. Generally, the wider the river the greater the curves as the water slows.ģ. It's sometimes easiest to lay the course with one width and use the 'Update' tool to make the widths different after. The smallest widths should be used at the highest point and widened in increments to the widest at the estuary. I recommend using the 'Freeform' network tool to create realistic curves as the river descends. Lay the river: Next it's time to plop the river along the ground you've sloped.


Then use the 'Slope Terrain' tool to make an even slope from top to bottom following the route of the river, including all the curves and bends.Ģ. Prepare the ground: Once you've identified the course of your river check that the source will be higher than the estuary by at least 50 metres. How to lay down the rivers(There are images above relating to each section below.)ġ.
