Water quality monitoring in Mekong river basin in Laos
Monitored variables in the Mekong river basin in Laos are Escherichia coli concentrations and physico-chemical measurements in stream water. Physico-chemical measurements include water temperature, electrical conductance at 25 °C, dissolved oxygen concentration and saturation, pH, oxidation-reduction potential, turbidity, and suspended sediment concentration.
Details about the monitoring setup and the variables measured at multiple spatial scales in the Mekong river basin in Laos can be found here.
Hydro-meteorological and soil loss monitoring in Houay Pano catchment
Monitored variables in Houay Pano catchment are: 6-min and daily rainfall, hourly climate variables (wind speed, relative humidity, solar radiation, temperature), aperiodic water level, aperiodic suspended and bed particulate matter, and annual land use. At microplot scale, monitored variables are soil surface features, surface runoff, and soil loss.
