etween the HEC-DSS file system and the geodatabase system. The conceptualframework for this transfer procedure is depicted below using each of thegraphical user interfaces and input-output files using icon-type representations.First, the process reads the target geodatabase and source DSS file to transfer theinformation over the time series tables inside the target geodatabase. Second, theprocess uses an application to transfer the flow time series records needed to beexchanged back into a HEC-DSS file for the HEC-RAS system and generates andupdates the corresponding flow, project, and plan file to obtain a new HEC-RASconfiguration.Figure 3.25 Time Series Transfer SchematicThe time series transfer procedure outlined above represents a two-stepprocess that works but can be impractical for “near real time operations”. Analternative to the time series transfer application procedure is to have the time65
