Newwater Regimes: An Editorial, Alida Cantor, Jacque Emel
Newwater Regimes: An Editorial, Alida Cantor, Jacque Emel
Geography Faculty Publications and Presentations
This editorial is an introduction to the special issue of Resources on New Water Regimes. The special issue explores legal geographies of water resource management with the dual goals of providing critiques of existing water management practices as well as exploring potential alternatives. The papers in the special issue draw from numerous theoretical perspectives, including decolonial and post-anthropocentric approaches to water governance; social and environmental justice in water management; and understanding legal ecologies. A variety of themes of water governance are addressed, including water allocation, groundwater management, collaborative governance, drought planning, and water quality. The papers describe and analyze water …
Winter Rain Versus Snow In Headwater Catchments: Responses Of An Unconfined Pumice Aquifer, South-Central Oregon, Usa, Michael L. Cummings, David A. Eibert
Winter Rain Versus Snow In Headwater Catchments: Responses Of An Unconfined Pumice Aquifer, South-Central Oregon, Usa, Michael L. Cummings, David A. Eibert
Geology Faculty Publications and Presentations
Winter precipitation in two headwaters catchments (elevation ~1600 m) in the rain shadow of the Cascades volcanic arc in south-central Oregon normally falls as snow. However, in water year 2015, winter precipitation fell mainly as rain. An eight year study of the unconfined pumice aquifer allowed inter-annual comparison of groundwater recharge during the freshet and discharge during the growing season. During these water years precipitation ranged from 67% (WY2014) to 132% (WY2017) of the 30 year average, and included the rain dominated winter of WY2015 when precipitation during the water year was 98% of the 30 year average. Change in …

Excessive water level fluctuation may affect physico-chemical characteristics, and consequently ecosystem function, in lakes and reservoirs. In this study, we assessed the changes of phytoplankton assemblages in response to water level increase in Danjiangkou Reservoir, one of the largest drinking water reservoirs in Asia. The water level increased from a low of 137 m to 161 m in 2014 as a part of the South–North Water Diversion Project. Phytoplankton assemblages were sampled four times per year before, during and after the water level increase, at 10 sites. Environmental variables such as total nitrogen as well as phytoplankton biomass decreased after …
Water Supply Planning In Virginia: The Future Of Groundwater And Surface Water, Jonathon Lubrano, Jeffrey Moore
Water Supply Planning In Virginia: The Future Of Groundwater And Surface Water, Jonathon Lubrano, Jeffrey Moore
Virginia Coastal Policy Center
This paper begins by exploring the current state of water resources planning and permitting. Then, considers current water demand in Virginia, as well as future challenges. Next is an examination of management structures from other states and a discussion of potential solutions to the water scarcity issue, including wastewater purification, the Hampton Roads Sanitation District’s (HRSD) Sustainable Water Initiative For Tomorrow (SWIFT) project, and desalination. The paper concludes with various next steps and policy recommendations that the Commonwealth should consider as dwindling water resources could hamper economic growth and threaten drought conditions, such as regional planning to achieve the optimal …
