Scope 
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.
