Climate changes and the ongoing intensification of agriculture effect in increased material inputs in watercourses and dams. To ensure an efficient and environmentally friendly water resource management, water management associations need means for efficient water monitoring as well as novel strategies to reduce the pollution of surface and ground water. Traditionally, water management associations operate large sensor networks to suffice their needs for hydrological and meteorological measurement data to monitor and model physical processes within the catchments they are responsible for. Implementing a comprehensive monitoring system often suffers from sparse coverage of insitu data. Due to the evolvement of the Copernicus satellite platforms, the broader availability of satellite data provides a great potential for deriving valuable, complementary information from Earth Observation data, that contributes to a detailed understanding of hydrological processes. Although the number of satellite data platforms that provide online processing environments is growing, it is still a big challenge to integrate those platforms into traditional workflows of users from environmental domains such as hydrology. Thus, in this paper, we introduce a software architecture to facilitate the generation of Earth Observation information targeted towards hydrology. The presented WaCoDiS System comprises several microservices as well standardized interfaces that enable a platformindependent processing of satellite data. First, we discuss the contribution of Earth Observation data to water monitoring and derive several challenges regarding the facilitation of satellite data
