Fig. 3: Comparison of nitrate removal across hydrologic conditions.
From: Beaver dams overshadow climate extremes in controlling riparian hydrology and water quality
a Change in nitrate removal, measured as percent deviation from steady-state hydrologic conditions, along a representative riparian flow path (58 m) under 2018 hydrologic conditions, with and without the beaver dam (blue and green lines, respectively), and 2019 hydrologic conditions (orange line). The mean of the initial hydraulic gradients in 2018 and 2019 was used to simulate steady-state conditions. b Cumulative nitrate removed in 2018 and 2019, expressed as mol NO3- removed per m2 cross sectional discharge area.
