  • Water level, discharge, temperature, conductivity and turbidity measured as a function of time (GMT) in the Capesterre river, at the Capesterre - La Digue hydrologic station. The station is equipped with a pressure sensor (CS451, Campbell Scientific Inc.) measuring the river stage, a turbidimeter (OBS3+, Campbell Scientific Inc.) measuring the turbidity of the river, a conductivity probe (CS547A, Campbell Scientific Inc.) monitoring the water conductivity, 2 temperature probes embedded in the conductivity and the pressure sensors. These sensors are connected to a datalogger (Campbell CR800) which records the data. A gaujing curve, regularly updated by the DREAL Guadeloupe, relates the river discharge to the water stage.

  • Water level, discharge, temperature, conductivity and turbidity measured as a function of time (GMT) in the Bras-David river, at the Maison de la Foret hydrologic station. The station is equipped with a pressure sensor (CS451, Campbell Scientific Inc.) measuring the river stage, a turbidimeter (OBS3+, Campbell Scientific Inc.) measuring the turbidity of the river, a conductivity probe (CS547A, Campbell Scientific Inc.) monitoring the water conductivity, 2 temperature probes embedded in the conductivity and the pressure sensors. These sensors are connected to a datalogger (Campbell CR800) which records the data. A gaujing curve, regularly updated by the DREAL Guadeloupe, relates the river discharge to the water stage.

  • DescriptionWater level, discharge, temperature, and conductivity measured as a function of time (GMT) in the Quiock creek station. The stream flows through a Venturi flume (exponential cross section, ISMA Type III) equipped with a pressure sensor (CS451, Campbell Scientific Inc.) measuring the water level in the flume, and a conductivity probe (CS547A, Campbell Scientific Inc.) measuring the conductivity and the temperature of the water. These sensors are connected to a datalogger (Campbell CR800) which records the data. A calibration curve relates the river discharge to the water level.

  • Local observers record water level and take photographs of the scale every 10 days during the wet season and about once a month during the dry season. For turbidity, water sample are collected by local observer, every 10 days during the wet season and about once a month during the dry season, and sent by bus to Bamako for analyzing turbidity using a turbidimeter. A value of turbidity of 1001 stands for a value exceeding the sensor sensitivity.
