Abstract: A computer automated hydrologic data acquisition system has been developed to support field monitoring of rainfall, streamflow, groundwater and conductivity. The basic system involves a Motorola 6811 Evaluation Board, battery power source, measurement specific sensor, and a lap-top computer to retrieve data and store it on a diskette. Data can be taken at prescribed intervals or as breakpoint data. In the case of discontinuous data, such as stormwater runoff, the system essentially sleeps between events, recording data only during runoff. The system is inexpensive and is built from readily available materials and computer hardware.
