Water Quality Enhancement Using Subsurface Detention
While underground detention systems have gained wide acceptance in the quantitative treatment of stormwater runoff, the potential exists for substantial water quality improvement. Although...

A Finite Element Analysis of Mach Reflection by Using the Boussinesq Equation
The numerical analysis of Mach reflection, which is the reflection of an obliquely incident solitary wave by a vertical wail, is presented in this paper. For the mathematical model in...

Model for Water Quality in Periphery of Distribution Systems
A model is presented for water travel time and chlorine concentration in periphery dead ends of the water distribution system. The model is developed under the premise that residential...

From Natural Disaster to Human-Caused Disaster
This paper deals with the assessment of the environmental effects of the channelization, which has been monitored throughout the first year after completion of the project. Although the...
