This research concludes with a discussion on the potential effects on river water quality due to dry weather spills, the impact of rainfall intensity and their potential to mobilize the microbial contamination and move towards a stormwater drain and be transported to a nearby water course. Overall, the objectives of this study were achieved and the transport of microbes can be estimated at different elapsed times depending on the relative humidity after a dry weather spill event, providing its impact on waterways.

This thesis analyses the Australian resources equity market reaction to the 2010 resource tax announcements. These taxes were explicitly designed to meet tax neutrality conditions. Tax neutrality implies that taxes should not incur substitution effects that result in economic inefficiency. These taxes were intended to generate revenue (i.e., an income effect) while not distorting economic incentives.

This research uses empirical data from a cross-sectional survey of households that was specifically designed to examine the vulnerability and resilience of households to global macroeconomic shocks. In early 2011 six communities in each country were surveyed, ranging from inner-urban squatter settlements of the respective capital cities to some of the most geographically distant areas in each country. The original contribution of this thesis is that it marks the first time that the micro effects of macroeconomic events are studied in such a broad range of communities in either country.

The southern part of the Western Anatolia Extensional Province is governed by E-W-trending horst-graben systems and NW-SE-oriented active faults. The NW-striking Yatağan Fault is characterised by an almost pure normal sense of motion with a minor dextral strike slip component. Although the settlements within the area have been affected by several earthquake events since ancient times (~2000 BCE), the earthquake potential and history of the Yatağan Fault has remained unknown until a few years ago.

We have investigated the time-dependent seismicity model of the earthquake occurrence on a regional basis through the North Anatolian Fault Zone (NAFZ). To that end, the studied region has been subdivided into 7 seismogenic zones considering the seismotectonic criteria, and then regional time and magnitude predictable (RTIMAP) model has been performed. Intervened times and magnitudes of main shocks produced in each zone have predictive properties defined by the RTIMAP.
