Description
Summary:A gauging station was installed in Carnivore Creek in May 2015. During that summer, water pressure, turbidity, temperature and conductivity measurements were acquired every half hour using a Troll9500. Water pressure was corrected for atmospheric pressure and converted in water level. A discharge rating curve was built during that summer by acquiring daily discharge measurement using an hand held Hach FH950 flow meter. Water samples were collected during the discharge measurement using a DH-48 and suspended sediment concentration (SSC) was obtained from filtration of the water samples. The same procedure was applied in 2016, in addition a hobo water level pro was added to the station in case of failure of the Troll9500. Suspended yield (SY) was reconstructed using multivariate models, where SSC (mg/L) was the dependent variable, and different combinations of hydrological, climate, and temporal variables were selected as explanatory variables for each creek. Q and unit conversions were used to convert modeled SSC (mg/L) to modeled SY (Mg/time).
