Singular Value Decomposition–Based Collocation Spectral Method for Quasi-Two-Dimensional Laminar Water Hammer Problems
(American Society of Civil Engineers, 2017)The radial distributions of velocity components need to be resolved in quasi-two-dimensional laminar water hammer problems. In a collocation spectra method, the radial distributions are approximated with Chebyshev expansions ... -
Local and Integral Energy-Based Evaluation for the Unsteady Friction Relevance in Transient Pipe Flows
(American Society of Civil Engineers, 2017)Unsteady friction and its modeling have been widely studied in transient pipe flows for its influences and modification effect on pressure waves. Such a feature is of great importance particularly in pipe systems where the ... -
Influence of Regular Surface Waves on the Propagation of Gravity Currents: Experimental and Numerical Modeling
(American Society of Civil Engineers, 2017)The propagation of gravity currents is analyzed in the presence of regular surface waves, both experimentally and numerically, by using a full-depth lock-exchange configuration. Full-depth lock-exchange releases have been ... -
Using an Improved Jet-Erosion Test to Study the Influence of Soil Parameters on the Erosion of a Silty Soil

What Controls the Transition from Confined to Unconfined Flow? Analysis of Hydraulics in a Coastal River Delta
(American Society of Civil Engineers, 2017)Recent field work at the Wax Lake Delta (WLD) in coastal Louisiana indicates lateral outflow from channels to islands upstream of the receiving basin; in this region of the delta the flow transitions from confined to ... -

Scaled Multiobjective Optimization of an Intensive Early Warning System for Water Distribution System Security
(American Society of Civil Engineers, 2017)Performance of an early warning system composed of online monitoring sensors for protecting municipal water supply is dependent on the number of sensors deployed. The inherent trade-off of performance versus scale of the ... -
Pump-As-Turbine: Characterization as an Energy Recovery Device for the Water Distribution Network
(American Society of Civil Engineers, 2017)The distribution of water is an energy intensive process in which potential to recover energy currently wasted exists, via the installation of microhydro energy recovery systems. Pump-as-turbine (PAT) technology offers an ... -
Assessing Erosion Hazards due to Floods on Fans: Physical Modeling and Application to Engineering Challenges
(American Society of Civil Engineers, 2017)Experiments using a 1∶30 scale physical model show that channel degradation on alluvial fans is dominated by lateral channel migration rather than vertical incision. The results are used to estimate the exposure probability ... -
