River networks connect landscapes and waterbodies while storing and transporting fluxes of water, sediment, and nutrients critical for ecosystem and human functioning. Understanding and predicting how river networks will adapt to climate stressors and human impacts requires blending knowledge of their structures with the dynamics occurring within these structures. New opportunities for characterizing both river network forms and functions are increasingly available as satellite technologies continue to expand. We aim to bring together studies of river network topology and morphology with those of their dynamics, including streamflow modeling, biogeochemical cycling, and flux transport. We welcome efforts focused on connectivity and toward creating, improving, or exploiting representations of river networks, such as applications/advancement of the National Water Model on the National Hydrography Dataset. Further, we invite contributions that feature novel river network mapping techniques from satellite images or DEMs. Studies on both tributary and distributary networks at any scale are welcome.
