Book excerpt: "The Nebraska Department of Natural Resources (NDNR) is tasked with conducting an annual evaluation of all Nebraska river basins not currently designated as fully appropriated, over-appropriated, or for which a status reversal has not occurred within the past 4 years. Recently, a new methodology for determining basin status in support of the annual evaluation was developed based on a re-creation of the Basin Water Supply (BWS). The BWS represents the water supply that is available for total use within a river basin, sub-basin, or reach. The BWS is calculated as the total of gaged streamflow, surface water consumptive use, and groundwater depletions. In the context of the new methodology, groundwater depletions are defined as groundwater use, which directly removes water from the BWS and ultimately reduces aquifer discharge (baseflow) to the streams. The general approach of the new methodology is to re-create a time series of the BWS from historical conditions through present day and assess groundwater depletions by comparing simulations of the BWS through time, with and without pumping and recharge associated with irrigation. NDNR is working to develop new tools or to customize existing tools to support the new methodology for determining basin status using the best scientific data, information, and methodologies available. Where feasible, numerical groundwater flow models are being used to provide quantitative estimates of historical groundwater depletions, via simulations of the historical BWS through the present day. NDNR has determined that an appropriate numerical groundwater flow model would be the best available tool for the annual evaluation in the Lower Niobrara, Loup, and Upper Elkhorn River Basins. NDNR contracted Brown and Caldwell (BC) to develop a numerical groundwater flow model to simulate the BWS in central Nebraska (Central Nebraska [CENEB] model . . . . The overarching goal of the project was to develop a modeling tool capable of simulating groundwater-surface water interactions in support of NDNR's annual evaluation of basin status, reproducing long-term trends under varying hydrologic and hydrogeologic conditions. The approach to CENEB model development was designed to meet this goal and demonstrate the appropriateness of the model for its intended use" (page 1-1).

Download or read book Groundwater Depletion in the United States 1900 2008 written by Leonard F Konikow and published by CreateSpace. This book was released on 2014-08-01 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: A natural consequence of groundwater withdrawals is the removal of water from subsurface storage, but the overall rates and magnitude of groundwater depletion in the United States are not well characterized. This study evaluates long- term cumulative depletion volumes in 40 separate aquifers or areas and one land use category in the United States, bringing together information from the literature and from new analy- ses. Depletion is directly calculated using calibrated ground- water models, analytical approaches, or volumetric budget analyses for multiple aquifer systems. Estimated groundwater depletion in the United States during 1900-2008 totals approx- imately 1,000 cubic kilometers (km3). Furthermore, the rate of groundwater depletion has increased markedly since about 1950, with maximum rates occurring during the most recent period (2000-2008) when the depletion rate averaged almost 25 km3 per year (compared to 9.2 km3 per year averaged over the 1900-2008 timeframe).
