Water issues, especially water scarcity and water pollution, have been affecting human lives and economic developments for a long time. Global climate changes exacerbate the probability and frequency of extreme events such as water scarcity and severe floods. The increasing irregular water supply and water pollution issues require more advanced water resources assessment methodologies to guide practical water use and management. This thesis presents the extended methods for water quantity-quality assessment and water-related energy consumption and emissions. Three major methodologies are proposed based on the Water Footprint concept and Water Pinch Analysis frameworks to assess the quantity and quality impact of water use. These methods are also demonstrated with numerical and empirical case studies targeting regional and industrial water resource assessment and optimisation. In addition, the Water-Energy Nexus is discussed to investigate the water issues from a broader perspective. An initial assessment of the water-related energy and GHG emissions of the seawater desalination industries is carried out. The studies in this thesis convey several contributions to the current water resource assessment methodologies. The proposed Water Availability Footprint made an initial effort to cover the water quality degradation impact into the existing water scarcity assessment frameworks, which was not addressed previously. The second contribution of this work is the proposal of the Quantitative-Qualitative Water Footprint (QQWFP), where a cost-based water footprint is defined and determined with the total cost of water consumption and removing contaminants generated during the water use process. The cost-based water footprint provides results which are more intuitive for water managers and the public and can better guide industrial and regional water use and management. The third contribution is the development of the Water Scarcity Pinch Analysis (WSPA), which applied the Water Pinch Analysis at a macro level for regional water use assessment and optimisation. All three proposed methods determine the water use impact in terms of water quantity and quality, and the QQWFP and WSPA also cover the impact of multiple contaminants. In addition to seeking solutions, this thesis also proposes potential directions for future investigations. Significant potential aspects to be further discussed include 1) a more advanced quantification method of the impact of multiple contaminants, and 2) an implementation and economic feasibility analysis of the WSPA and QQWFP with localised data, which seek a customised solution to regional and industrial water use optimisation.
