Scenario 1Stream monitoring & flood event• Scenario 1 can be broken down into 3 activities1) Monitoring: The system periodically monitors stream and ground watergauges and tracks their last value2) Subscription: An EM analyst indicates his/her desire to be notified of anevent of interest – such as a flood – by choosing a monitoring point andsubscribing to all the stations upstream of that point3) Notification: The system checks the monitored values from activity 1 againstthresholds specified in activity 2 to determine if a flood is imminent andnotification is required
