Reed WB, Schwartz SS, Hammerschlag RS. 1990. ELARC: Hydrologic Forecasting for Floodplain Management Within the Potomac River Basin - Phase 1. Technical Report NPS/NRWRD/NRTR-90/04 (NPS D-84). National Park Service, Water Resources Division. Fort Collins, CO
The Enhanced Limited Automatic Remote Collection (ELARC) system is a microcomputer-based hydrologic forecasting system that uses real-time streamflow data retrieved by telephone line from upstream data loggers. The ELARC system generates a computer screen displayed report, including a hydrograph for the target gage. The system was developed for the Chesapeake and Ohio Canal National Historical Park by the Interstate Commission on the Potomac River Basin in conjunction with the National Weather Service and the National Park Service. The system is being implemented by the National Park Service in two phases. Phase 1 forecasts flows which can result in drownings in the vicinity of the Great Falls of the Potomac. Since the majority of these deaths occur when the Potomac River stage is below bankfull, the system was designed to forecasts subtle changes in the corresponding flows. Phase 2 will require system refinements to forecasts flood flows that necessitate management actions to protect park structures.
