Integrating water resources management : analysis of the St. Thomas, U.S. Virgin Islands, water market
… study includes the assessment of available water supply and water demand by use, and the evaluation of alternative and feasible supply options to augment freshwater resources. Three potential main supply strategies for freshwater supply were identified and compared based on: 1) economic efficiency …

Determining the socio-economic value of groundwater: Franschhoek case study
… being explored as a possible contributor to the freshwater supply. Development of the resource has been slow despite the existence of significant potential groundwater resources in the form of several shallow primary aquifer systems and an extensive secondary aquifer formation known as the Table …

Solar-driven humidification dehumidification desalination for potable use in Haiti
… technologies on a wider scale to contribute to freshwater supply. Small-scale desalination technologies, such as solar-driven humidification dehumidification (HDH), are needed to help provide clean drinking water to people living in coastal areas. This thesis explores the question of whether the …
