Resumo:  The western extension of the World Health Organization (WHO) project to combat onchocerciasis (river blindness), mainly in Guinea, calls for realtime access to flow level data concerning the rivers to be treated. The correct amount of larvicide to be applied, as a function of flow, can thus be calculated. The Argos system was chosen for data transmission. The transmitter is connected to water depth measurement hardware produced by Elsyde and CEIS-Espace and designed around a relative piezoelectric sensor and an EPROM-based data storage unit. This unit stores the hydrometric data and transmits messages containing the last 15 water depth measurements made on the hour and half-hour. The direct readout station contains a microcomputer which inputs data to the hydrometric data bank in realtime and is itself connected to a second microcomputer. This converts water depths into flow terms and makes a prediction, either by correlation or by inter-station analysis, of the flow at each relevant position over the coming five or ten hours. It also calculates the concentration of insecticide to apply to each stretch of the river. Only by automating the acquisition, data transmission, and flow prediction functions can the program be conducted on an operational basis at low cost.
