Stream Energy Impacting Sediment Transport Through Low-Gradient Agricultural Streams, Paula Jane Pryor
Stream Energy Impacting Sediment Transport Through Low-Gradient Agricultural Streams, Paula Jane Pryor
Theses and Dissertations
Water quality can be severely impacted by increased sediment transport, particularly agriculturally-dominated systems like those found in central Illinois. Many low-gradient sediment studies focus on the fine material transported in suspension. However, coarse-material transport can be equally important for understanding sediment loads to surficial reservoirs for local drinking water. To address a general gap in knowledge of coarse-sediment transport through agricultural streams, seasonal changes and watershed differences in sediment transport were examined in a low-gradient system. This was accomplished through the installation of bedload traps, scour-fill markers, and bank erosion pins at two streams, Six Mile Creek and Money Creek …

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, Zachary David Kisfalusi
Theses and Dissertations
Tile-drains remove excess water from agricultural fields and channel it directly to the nearest surface water body decoupling the system from the natural flow paths. One way to measure the effects tile drains have on streams is to monitor the thermal energy both upstream and downstream of the tile input. In the temperate climate, a stream’s thermal signature experiences large fluctuations seasonally along with small diurnal changes. In contrast, groundwater temperature does not show these small-scale changes, and the seasonal changes are often muted and lagged in comparison to surface water. This project aimed to quantify any thermal change to …
