Abstract

We study the flow of water on fat terrains, that is, triangulated terrains where the minimum angle of any triangle is bounded from below by a positive constant. We give improved bounds for the worst-case complexity of river networks on fat terrains, and show how to compute the river network and other flow-related structures i/o-efficiently.
