MODFLOW, MT3D-USGS and VS2DH simulations used to estimate groundwater and nutrient inflow to Upper Klamath Lake, Oregon MODFLOW, MT3D-USGS and VS2DH simulations used to estimate groundwater and nutrient inflow to Upper Klamath Lake, Oregon
One-dimensional vertical models of GW flow (MODFLOW-2005) and solute transport (MT3D-USGS) were calibrated (UCODE) to 2014 observed dissolved silica (Si, 0.2-micron filtered) porewater concentrations in the upper 0.1 m of lakebed sediment to estimate GW flow and Si exchange across the lakebed interface. The Si-based calibrated GW flow rates were then used in conjunction with observed...
Depth-to-water data and calculated vertical hydraulic gradient at the sediment-water interface in Upper Klamath Lake, Oregon, 2017 Depth-to-water data and calculated vertical hydraulic gradient at the sediment-water interface in Upper Klamath Lake, Oregon, 2017
Ten groundwater piezometers and lake-level stilling wells were deployed in Upper Klamath Lake (UKL), Oregon during May through October 2017. Piezometers and stilling wells were deployed in pairs so that water levels could be measured relative to a common measuring point (MP) at each location. Piezometers were installed in the lakebed sediment, with screens from 3.92 to 4.92 feet below...
