Geysering Caused by the Sudden Release of Pressurized Air Pockets
(2017-04-26)
Uncontrolled air pockets released from water filled shafts can lead to geysering in stormwater systems. Such occurrences are deleterious from public health and environmental standpoints and can cause property and structural ...
Design and Construction of a Rainfall Simulator for Large-Scale Testing of Erosion Control Practices and Products
(2017-04-14)
Soil erosion and the resulting sediment deposition constitutes one of the greatest pollutants in our nation’s waterways. Construction projects often generate large areas of exposed soil that remain disturbed throughout the ...
Cellular Confinement as a Means to Limit Sediment Resuspension
(2017-07-22)
This document contains the findings of experimental research that examines the effectiveness of small-scale confinement cells within the context of sediment basins, channels, or ditches. The confinement cells were tested ...
Evaluating the Effects of Queue Warning Systems on Freeway Work Zones Using Traffic Simulation Software
(2017-07-27)
Work zones are a key component of the rehabilitation efforts that travelers on the U.S. national highway system interact with increasingly every day. Roadway construction, rehabilitation, and maintenance poses a potential ...
Immobilization of lead from aqueous solution by using carboxymethyl cellulose stabilized iron sulfide nanoparticles
(2017-11-27)
Lead pollutant has attracted more attention recently. Moreover, the use of patent iron sulfide nanoparticles is more and more extensive for various contaminants removal. In this study, FeS nanoparticles is prepared with ...
Experimental Testing of a Rotational Friction Connection for Use with Precast Concrete Cladding Panels in Metal Building Systems
(2017-11-27)
Lightweight clad metal building systems have been shown to exhibit excellent performance in seismic events; however, metal building systems clad in masonry or precast concrete panels (hard walls) have been shown through ...
Evaluating and Understanding of Bridge Scour Calculation
(2017-11-27)
Channel scour and channel instability at bridges are the major cause of bridge collapse caused by flooding. Currently, Departments of Transportation (DOTs) in the USA use the HEC-18 procedure and associated software, which ...
A Fine Line Between Dispersion and Retention: Oil-Sediment Interactions in Nearshore Marine Environments
(2017-04-12)
When crude oil that is spilled in a marine environment approaches the shoreline, it can interact with suspended sediment to form either microscopic oil-mineral aggregates (OMAs), or macroscopic surface residual balls (SRBs) ...
Modeling of the Wolf Bay and Perdido Bay Watersheds using HSPF
(2017-07-27)
This study is the first stage of the larger project for determining the transport mechanism of endocrine disruptors that flow through the Perdido Bay Basin. Given within are the methods and processes used to perform watershed ...
Design of Lateral Support for Non-Integral Wing Walls of Culverts
(2017-11-20)
Traditionally, culverts are built with integral wing walls. This style of culvert has shown consistent issues at the joint where the wing wall frames into the culvert bodies due to differential settlement and inadequate ...
