OGC Climatology-Hydrology Information Sharing Pilot - This use case focuses on exchanging cross-border hydrologic data (stream flow and groundwater levels) with a unified alert service. Stream/river gauge and groundwater well locations are associated with a river network that in turn is associated with a set of basins (watersheds) (For the purposes of this Pilot, a simple geometric buffer will be used to identify gauge and well locations rather than catchments). For any well or stream gauge location, a web service provides access to the gauge and well information on all upstream stream segments or in all contributing basins. An event service provides subscribers a notification if any upstream streamflow or well water level reaches or exceeds a user-defined threshold. Selected river basins cross the U.S./Canada border. Data providers include state, provincial, and federal agencies. Based on sensor events, a flood is determined to be imminent and alerts are sent to the authorities in the affected areas.
