Abstract

An Early Flood Warning System provides advanced warning of probable flash floods and/or stage floods to potential flood victims by collecting and analyzing rainfall and stream level data, and by providing means for disseminating alarms and instructions to individuals in threatened areas. Said Early Flood Warning System contains: a plurality of automated electronic digital liquid level gauges, some of which are specially adapted as rain gauges, and some of which are specially adapted as stream level gauges; a plurality of gauge actuated transmitters; a receiver; a decoder and validity logic unit; a data analysis unit; a central disaster alert station; and a plurality of disaster alert modules. Said digital liquid level gauges are energy and environmental intensive devices which electronically measure, using digital techniques, liquid levels such as rainfall and stream level, and transmit data by coded radio frequency (R.F.) signals to a central data analysis facility. Said digital liquid level gauges are remotely located and independent of each other.
