2D and 3D Computational Modeling of Surface Flooding in Urbanized Floodplains: Modeling Performance for Various Building Layouts

open access: yesWater Resources Research, Volume 60, Issue 5, May 2024.
Abstract Understanding the strengths and limitations of the modeling capacity of surface flooding in urbanized floodplains is of utmost importance as such events are becoming increasingly frequent and extreme. In this study, we assess two computational models against laboratory observations of surface urban flooding in a reduced‐scale physical model of

Turbulent flow dynamics and mass transport processes in a natural surface storage zone using field data and numerical simulations

open access: yesE3S Web of Conferences, 2018
In this work, the turbulent flow dynamics and mass transport mechanisms in a natural SSZis analyzed. The study site is a river reach of the Lluta River, located in northern Chile in a high-altitude Andean environment known as the Altiplano (~ 4,000 masl)

Optimization of Snow Drifting Mitigation and Control Methods for Iowa Conditions Part II, TR-626, 2015 [PDF]

open access: yes, 2015
Blowing and drifting of snow is a major concern for transportation efficiency and road safety in regions where their development is common. One common way to mitigate snow drift on roadways is to install plastic snow fences. Correct design of snow fences

Remote sensing of laboratory rivers

open access: yesEarth Surface Processes and Landforms, Volume 49, Issue 1, Page 58-81, January 2024.
Remote sensing can be adapted for the lab to monitor the evolution of physical experiments without disrupting their processes. We review ways to deploy ‘remote sensing’ for experiments in fluvial geomorphology. We hope this paper will be helpful for experimentalists who want to collect data both continuously and cost‐effectively.

STANDARD FOR APPLICATION METHOD OF LSPIV TO SURFACE VIDEO RECORD OF ACTUAL FLOOD FLOW

open access: yesPROCEEDINGS OF HYDRAULIC ENGINEERING, 2007
Using a surface video record of a large-scale flood in Yoshino River, Shikoku, Japan, some problems related to application method of Large Scale Particle Image Velocimetry (LSPIV) are examined in detail. First, from a hydraulic point of view, a new method is proposed for exclusion of incorrect velocity data and calculation of time-averaged velocity ...

Velocity profiles and interface instability in a two-phase fluid: investigations using ultrasonic velocity profiler [PDF]

open access: yes, 2018
In the present study the velocity profiles and the instability at the interface of a two phase water-oil fluid were investigated. The main aim of the research project was to investigate the instability mechanisms that can cause the failure of an oil ...
