Examining The Relationship Between Manning's Roughness Coefficient And Stage, Henry Holtkamp
Examining The Relationship Between Manning's Roughness Coefficient And Stage, Henry Holtkamp
Biological and Agricultural Engineering Undergraduate Honors Theses
This paper uses LOESS regression to predict Manning's roughness coefficient to calculate flows in natural stream channels. Manning's roughness coefficient can introduce variability into Manning's equation, potentially destabilizing results. Utilizing LOESS to find n based on backcalculated n from collected discharge vs. stage information is the best way to acquire accurate Manning's roughness coefficient values at a variety of flows. Book values tend to drastically overestimate which can have wide-ranging implications for water allocation, flood management, maintaining environmental flows, and maintaining water quality.
Exploring The Effects Of Varied Land Use On Elemental Concentrations Within Streams, Logan Jennings
Exploring The Effects Of Varied Land Use On Elemental Concentrations Within Streams, Logan Jennings
Biological and Agricultural Engineering Undergraduate Honors Theses
It is well documented that human activity influences the chemistry of surrounding waters. As such, it is possible that there is a link between land use within a watershed and the chemical composition of the stream. The objectives of this study are to determine if varied land use does affect the concentrations of macronutrients and trace elements present in the streams of Northwest Arkansas, and if so, to determine what extent urban and agricultural development are responsible for these changes. Water samples were collected across 19 streams in the Northwest Arkansas region between January and March of 2022. Water samples …
