The analysis of water pipes failure data is of great importance as it has a significant impact society and the environment. These failures also have the overall impact on the financial burden on the water industry. This ...
Comparative Analysis Of Flood Frequency Based On Radar-based Precipitation Data And Precipitation Trends
(Civil & Environmental Engineering, 2014-09-17)
This study utilizes radar-based precipitation data from the National Weather Service West Gulf River Forecast Center to extract the depth-area-duration relationships via the U.S. Army Corps of Engineers' software HEC-MetVue. ...
Non-destructive SASW Evaluation Of Controlled Low Strength Material As A Pipeline Bedding Material
(Civil & Environmental Engineering, 2014-09-17)
Evaluation of stiffness properties of subsurface soil layers provides vital insight into the performance of a geotechnical entity. Stiffness properties can be determined by both field and laboratory tests. Owing to their ...
Performance Of Large Diameter Polyvinyl Chloride (PVC) Pipes In Water Applications
(Civil & Environmental Engineering, 2014-03-10)
Polyvinyl chloride (PVC) pipes with diameters greater than 24" make up a small fraction of water utilities. Most of the research done on PVC pipes in water utilities focuses on diameters less than 24". Therefore, this ...
Improving Analysis Of Heavy To Extreme Precipitation Using Conditional Bias-penalized Optimal Estimation
(Civil & Environmental Engineering, 2014-03-10)
Precipitation estimation is a very important topic from the societal perspective as heavy precipitation can cause flooding from which loss of lives and damage to properties can occur. In current practice, a number of spatial ...
The Relation Between Freeway Average Speed And Speed Noise
(Civil & Environmental Engineering, 2014-09-17)
A significant amount of energy could be saved by applying traffic management policies. Many factors affect the fuel consumption rate, and the most important traffic-related ones include variables such as speed, number of ...
