Skewed Approach Flow To The Spillway Of An Embankment Dam, C. I. Thornton, J. Ellis, F. Alsultan, C. Volt, R. Ettema Apr 2025

Skewed Approach Flow To The Spillway Of An Embankment Dam, C. I. Thornton, J. Ellis, F. Alsultan, C. Volt, R. Ettema

5th International Seminar on Dam Protections Against Overtopping

A contemporary activity in dam engineering is the raising of embankments to increase reservoir storage or flood level in a channel. For embankment dams, the raised position of the spillway must be located on a native soil/rock shoulder of the dam, to avoid geotechnical problems associated with possible embankment settlement. Consequently, for many sites, the approach flow entering a spillway likely will not be acceptably uniform, as the approach flow becomes increasingly skewed to reach the spillway’s entrance with the raised embankment. This concern raises the question of where to position the spillway’s ogee crest within the spillway entrance and …

Method For Low-Cost In Situ Measurement Of Dissolved Total Volatile Organic Compound Concentrations In Surface Waters, Teagan A. Jones Apr 2025

Method For Low-Cost In Situ Measurement Of Dissolved Total Volatile Organic Compound Concentrations In Surface Waters, Teagan A. Jones

ATU Scholars Symposium

Increases in volatile organic compounds (VOC) in developing areas poses risks to aquatic health. Water quality changes in surface waters, if measured, are often only for field parameters of pH, specific conductance, water temperature, and major ions, e.g. Ca2+, Mg2+, Na, Cl. Elevated VOC concentrations can negatively impact aquatic ecosystems even at low concentrations, but do not cause changes in commonly measured parameters and may go undetected based on monitoring these common parameters. Traditional sampling and benchtop analysis for VOC can be both time and cost prohibitive. Here we demonstrate the use of a low-cost in situ dissolved total VOC …

Enabling Localized Execution Of Smart Contracts Via Distributed Event Beacons, Rakesh Vasa, Sky P. Waterpeace, Nick Ivanov

STEM Student Research Symposium Posters

Modern smart contracts save their state transitions on a distributed ledger, such as blockchain [3, 4] or a particularly configured cloud [1]. These approaches necessitate storage and synchronization of large amounts of distributed data, leading to scalability deficiencies in decentralized permissionless smart contract platforms. In this poster, we introduce a novel concept of local execution of smart contracts which only required synchronizing the transaction data between the members of the private channel, without the need to storing state transitions on the distributed storage. To achieve this, we design a distributed storage-free decentralized beacon network that allows to perform provenance signatures …
