Surface water global indices

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.

Capmes is an instrument capable of measuring the water level and the concentration of suspended matter in rivers with a time step going from one measurement every hour at low flow to one measurement every 2 minutes during a flood. The instrument, designed by IPGP, is based on the use of a LISST-25X optical sensor (Sequoia Scientific Inc.) [Limare et al., 2010; Lajeunesse et al., 2011]. The latter is incorporated in a complex hydraulic and electronic system controlled by a datalogger. As a result, it functions as s stand-alone instrument capable of 1) performing long surveys with a minimum human intervention and 2) acquiring data even under extreme climatic events. This instrument was developed and tested during a 1.5 years field survey performed from June 2008 to January 2010 on the Capesterre river located on Basse-Terre island (Guadeloupe archipelago, Lesser Antilles Arc).

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.
