New Solutions For The Propagation Of Long Water Waves Over Variable Depth, Yinglong Zhang, Song-Ping Zhu
New Solutions For The Propagation Of Long Water Waves Over Variable Depth, Yinglong Zhang, Song-Ping Zhu
Faculty of Engineering and Information Sciences - Papers: Part A
Based on the linearized long-wave equation, two new analytical solutions are obtained respectively for the propagation of long surface gravity waves around a conical island and over a paraboloidal shoal. Having been intensively studied during the last two decades, these two problems have practical significance and are physically revealing for wave propagation over variable water depth. The newly derived analytical solutions are compared with several previously obtained numerical solutions and the accuracy of those numerical solutions is discussed. The analytical method has the potential to be used to find solutions for wave propagation over more natural bottom topographies.

In this paper, problems associated with mine waste water discharge quality in two mines are examined in the environmentally sensitive regions in NSW, Australia. In the first mine the problem of controlling and treating surface run-off from a large coal mine site is duscussed. Then study involved sampling and analysis of mine wastewater during various weather conditions over a period of six months. The samples were analysed for a range of physical and chemical water quality parameters. The study indicated that during minor storms, the mine wastewater treatment system worked effectively, but during a moderate to major storm, the treatment …
