Groundwater -- surface water interaction under the effects of climate and land use changes.

Historical observed data and future climate projections provide enough evidence that water resources systems (i.e., surface water and groundwater) are extremely vulnerable to climate change. However, the impact of climate change on water resources systems varies from region to region. Therefore, climate change impact studies of water resources systems are of interest at regional to local scales. These studies provide a better understanding of the sensitivity of water resources systems to changes in climatic variable (i.e., precipitation and temperature), and help to manage future water resources. In addition to climate change, human-induced land use changes also significantly affect water resources systems. Therefore, climate and land use changes can provide offsetting and additive impacts on water resources systems depending on the region and watershed characteristics. In this dissertation research, groundwater-surface water (GW-SW) interaction under the effects of climate and land use changes were investigated through the development of a Gridded Surface Subsurface Hydrologic Analysis (GSSHA) modeling system using a case study in Kiskatinaw River watershed (KRW), British Columbia, Canada. --Leaf i.
