The Effects of Tile Drain Input on a Low-Gradient Agricultural Stream in Central Illinois: Using a Thermal End Member Mixing Model and a Statistical Analysis Approach

Understanding 1-D Vertical Flux Dynamics In A Low-Gradient Stream: An Assessment Of Stage As A Control Of Vertical Hyporheic Exchange

“…Peterson and Sickbert (2006) found that the hydraulic head of the water table near the creek mimics the stage of LKC with a minimal lag time between the peak stage during a flood event and the measured hydraulic head in the aquifer (Peterson and Sickbert, 2006). At the regional scale, LKC is considered a gaining stream that has a baseflow of 0.1 m 3 /s (Peterson and Sickbert, 2006) with external inputs from agricultural tile drains (Kisfalusi, 2016). Tile input does not alter the thermal conditions in the stream because the tile discharge is not significant enough to overcome the streams thermal inertia.…”
