1D and 2D Flow Routing on a Terrain
ACM Transactions on Spatial Algorithms and Systems (TSAS), Volume 9, Issue 1Article No.: 3, Pages 1–39https://doi.org/10.1145/3539660An important problem in terrain analysis is modeling how water flows across a terrain creating floods by forming channels and filling depressions. In this article, we study a number of flow-query-related problems: Given a terrain Σ, represented as a ...
