Analytical And Experimental Study Of A Three Dimensional Internal Hydraulic Jump In A Shallow Channel Of Limited Width, Zoheb Nasir

Electronic Thesis and Dissertation Repository

The main objective of this thesis is to study the hydraulic behaviour of a surface heated discharge in a shallow channel, which is wider than the discharge of thermal waste, and connected to a colder water body. An internal hydraulic jump characterized by mixing (dilution) of hot and cold water was observed in the channel. Similar to the single-layer hydraulic jump, the internal hydraulic jump in a two-layer system is a rapid transition from supercritical to subcritical flow.

The study involved analytical and experimental analyses of the flow in the channel. The analytical analysis showed that the critical dilution initially …

Application Of A K-Nearest Neighbour Weather Generator For Simulation Of Historical And Future Climate Variables In The Upper Thames River Basin, Leanna M. King

Electronic Thesis and Dissertation Repository

Climate change has the potential to significantly alter the hydrologic cycle, changing the frequency and intensity of precipitation events in an area. It is necessary to quantify these effects to effectively manage water resources in the future. Atmosphere-Ocean coupled Global Circulation Models (AOGCMs), often used in climate change research, have spatial resolutions that are too large to capture the local climate characteristics of a watershed. As a result, several downscaling tools have been developed, including stochastic weather generators. A methodology for the simulation of historical and future climate data using a nonparametric K-Nearest Neighbour block resampling weather generator with perturbation …
