Automatic measurement of water level converted into flow and electrical conductivity at the outlet of a 1st order catchment along specific vegetation catena (fallow, forest, bush savannah). The catchment is constituted of hillslope and a bas-fond. For small stream, calibration of the stage-discharge relationships is made by stream-gaging surveys using a wading-rod (velocity-area method). A value = 9999 stands for a dry gully.

Automatic measurements of water levels in creeks converted into flow.

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.

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.
