河流网络通过在整个生态系统和社区中运输和分配水、沉积物和营养物质来维持生命和景观。在最大规模上，河流网络通过树状的支流网络将大陆吸干。在典型的小尺度上，河流三角洲和辫状河通过剥离和分岔形成环状的、复杂的分流河网。为了对流经这些网络的流进行建模或分析网络结构，必须解决网络的拓扑或连通性问题。此外，每条河道的形态特性以及流经河道的水流方向都能告诉我们通量如何在网络的河道中传播。
River networks sustain life and landscapes by carrying and distributing water, sediment, and nutrients throughout ecosystems and communities. At the largest scale, river networks drain continents through tree-like tributary networks. At typically smaller scales, river deltas and braided rivers form loopy, complex distributary river networks via avulsions and bifurcations. In order to model flows through these networks or analyze network structure, the topology, or connectivity, of the network must be resolved. Additionally, morphologic properties of each river channel as well as the direction of flow through the channel inform how fluxes travel through the network’s channels.
