  • Water level, discharge, water temperature, conductivity and turbidity measured every ten minutes in the Bras-David river, at the Maison de la Forêt site. A hydrologic station, located at the « Maison de la Forêt » site, monitors the hydrology of the Bras-David river. 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.

  • 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.

  • Flood event measured in 4 (Tondikiboro) and 2 (Mele Haoussa) embeded catchments. Sediment loads are sampled during selected rainfall events in Tondikiboro.
