The dynamics of water and sediments from land to the ocean, such as hillslope runoff generation, river flow and flooding, sediment transport and geomorphology, and coastal river plumes, are inter-connected through processes with various spatial- and temporal-scales. As compound disasters and environmental changes often involve these processes occurring simultaneously at multiple scales, integrated understanding of the dynamics of water and sediments across hillslope, floodplain, river mouth, and coastal-zone are required. We welcome wide-range studies related to the dynamics of water and sediments from land to the ocean with theoretical, observational, and simulation-based approaches such as basic process understanding, in-situ and remote-sensing observations, big-data analysis and supercomputing. (We also have a corresponding English).
