✦ Synopsis
The system described in this paper uses a commercial, portable computer to monitor rainfall, surface runoff, soil moisture potential, soil temperature, and water table levels. The system is designed as a permanent field instrument which reads 16 analogue and two digital channels. It offers 10-bit accuracy and records data on both magnetic tape and paper for greater security. The computer program is in Microsoft BASIC and can therefore be readily altered to change the measurement regime. Although designed to investigate the infiltration process the system is easily adapted to monitor other environmental processes.
