Numerical Investigation Of Usbr Type Iii Stilling Basin Performance Downstream Of Smooth And Stepped Spillways, Daniel Valero, Daniel Bung, Brian M. Crookston, Jorge Matos

International Symposium on Hydraulic Structures

Recent systematic studies on air-water flows have included stepped spillways. However, to date little has been investigated about how the hydraulic conditions on the stepped spillway may affect the design of traditional energy dissipation structures. In this paper, both smooth chute and stepped chute configurations terminating with the USBR type III stilling basin are tested by means of numerical modelling, allowing a qualitative comparison. Unsteady RANS equations have been employed altogether with VOF and RNG k-ε for free surface tracking and turbulence modeling, respectively. Eight different Froude numbers (F) ranging from 3.1 to 9.5 have been analyzed for a type …

Baffle Designs To Facilitate Fish Passage In Box Culverts: A Preliminary Study, H. Chanson, W. Uys

International Symposium on Hydraulic Structures

Waterway culverts and road crossings are very common design in water systems, ranging from rural roads to national highways and urban drainage networks. Engineers and biologists need better, more reliable prediction 'tools' during the design stages to compare the bio-engineering performances of a range of design options. Present expertise in environmental hydraulics of culverts is deficient because of the many empirically-based design guidelines which are sometimes outdated and often inadequate for fish passage. In all the cases, the turbulence of the flowing waters must be optimised efficiently to maximise fish migration. This project focused on the development of simple solutions …

Spillway Rock Scour Analysis - Composite Of Physical & Numerical Modelling, Paradise Dam, Australia, E. J. Lesleighter, E. F.R. Bollaert, B. L. Mcpherson, D. C. Scriven

International Symposium on Hydraulic Structures

A number of problems and solutions of rock scour downstream of spillways have been evaluated using a composite approach, based on the gathering of detailed data from a physical model and utilising those data in a sequence of calibration and application of numerical modelling of the scour. Our paper will describe the application of the Computational Scour Model (CSM - Bollaert, 2002 and subsequent) as the numerical procedure that makes the composite approach a proven methodology for such problems. The paper will focus on a case study application of the procedure based on the experiences of flooding and scour at …

Interaction Of Hydraulic Structures With Air, Water, And Rock: The Challenge Of Researchers And Designers, Anton J. Schleiss

International Symposium on Hydraulic Structures

Since the last ten years, financial crisis has strongly impacted the global economy, which was mainly the result of un-controlled financial speculations at the stock markets highlighted by the revelations regarding offshore companies. Fortunately, the field of construction of large infrastructures, such as hydraulic schemes, has been left relatively untouched by this crisis. In order to stimulate their economies, many governments across the world have injected significant sums into sustainable infrastructures development.

Hydraulic Structures And Water System Management-Ishs2016 In Perspective, Brian M. Crookston, Blake Tullis

International Symposium on Hydraulic Structures

Hydraulic structures are vital features in our water infrastructure, as they help meet the diverse and challenging demands of society, including conveyance, flood protection, environmental and ecological impacts, and systems management. Indeed, there are a number of challenges facing engineers today. This 6^th IAHR International Symposium on Hydraulic Structures (ISHS2016) brought together domestic and international expertise from research, practice, and implementation in a forum for knowledge exchange and networking discussion on critical issues related to hydraulic structure research, performance, operations, maintenance, and community implications. It continued the rich tradition of this series by stimulating interest on advancement in the …

June 10, 2016 – Utah State University offered nearly $1 million in scholarship funding on Thursday to a group of high school students attending their last day of a weeklong engineering summer camp.

The juniors and seniors were participating in the annual Engineering State, or ‘E-State’ event designed to introduce young people to engineering and computer science. On Thursday the group attended a closing awards banquet where 80 out of240 students were offered scholarships ranging from $2,000 to $41,000.

This Desert Moss Has Developed The Ultimate Water Collection Toolkit | College Of Engineering, Usu College Of Engineering

College of Engineering News

LOGAN, UTAH – June 6, 2016 – Finding water in the desert is a relatively easy task for a species of moss that seems to flourish in even the most arid regions. That’s according to a new study by a team of scientists and engineers who wanted to understand how Syntrichia caninervis succeeds despite its limited and inconsistent water supplies.

The findings show for the first time how the highly evolved bryophyte survives in extremely arid environments thanks in part to its specialized water collection and transportation toolkit.

Swiftgpu: Fostering Energy Efficiency In A Near-Threshold Gpu Through A Tactical Performance Boost, Prabal Basu, Hu Chen, Shamik Saha, Koushik Chakraborty, Sanghamitra Roy

Electrical and Computer Engineering Faculty Publications

In this paper, we investigate the challenges of preserving energy-efficiency in a Near-Threshold Computing (NTC) GPU. Two key factors can significantly undermine the efficacy of GPUs at NTC: (a) elongated delays at NTC make the GPU applications severely sensitive toMulti-cycle Latency Datapaths (MLDs) within the GPU pipeline; and (b) process variation (PV) at NTC induces a substantial performance variance. To address these emerging challenges, we propose SwiftGPU - -an energyefficient GPU design paradigm at NTC. SwiftGPU dynamically adjusts the degree of parallelization, and the speed of the MLDs within each stream core of the GPU. The proposed scheme achieves an …

Catching The Flu: Emerging Threats From A Third Party Power Management Unit., Rajesh Jayashankarashridevi, Chidhambaranathan Rajamanikkam, Koushik Chakraborty, Sanghamitra Roy

Electrical and Computer Engineering Faculty Publications

Power management units (PMU) have come into the spotlight with energy efficiency becoming a first order constraint in MPSoC designs. To cater to the exponential rise in power events, and to meet the demands of tight power and energy budgets, PMUs are evolving to more complex and intelligent designs. In an era defined by energy efficient computing, a malicious circuit embedded in a third party PMU can adversely affect the operation of the entire MPSoC. This work presents and evaluates two covert security threats, P-VIRUS and DROWSY, designed using a malicious third party PMU. Further, we propose a non-invasive IP …
