River Device – World Machine Help
Your river will have a very different character depending on which River GCS you select to use for the river. Sharp bends in the river valley may sometimes cause odd "kinks" or cliffs in the resulting river valley. These are unsightly but can be effectively removed by eroding the resulting output (See the article on Erosion and River Systems)
