Residence Times And Temporal Variations Of 210Po In Aerosols And Precipitation From Southeastern Michigan, United States, Daphne Mcneary, Mark Baskaran

Environmental Science and Geology Faculty Research Publications

Daughter products of ²²²Rn (such as ²¹⁰Pb, half-life = 22.1 years, and ²¹⁰Po, half-life = 138 days) have been widely used as tracers to determine the removal rates of aerosols as well to obtain analog information on the behavior of other chemical species in the lower atmosphere. To establish the first data set on the depositional fluxes of ²¹⁰Po in bulk precipitation and concentrations in air samples from the midwestern United States, we measured the depositional fluxes of ²¹⁰Pb and ²¹⁰Po in the bulk (wet plus dry) and dry fallout by deploying a rain …

West Midlands Region Catchment Appraisal 2007, Angela Stuart-Street, Northern Agricultural Region Catchment Appraisal Team

Resource management technical reports

Annual run-off likely to occur was calculated for farm-scale catchments within the 500-825 millimetre rainfall zone of the South West Catchment Council [Western Australia] area. When compared with historical flow measurements, this method was found to be accurate (or conservative) in 85% of all measured years, indicating its usefulness for predicting reliable annual flows.

Agricultural Climatology, Kenneth G. Hubbard

High Plains Regional Climate Center: Staff Publications

With the diversification of the U.S. economy over the past century, agriculture has changed. We can say the farm sizes have increased over time, the number of farmers and those employed in farming have decreased over time, and as the economy has grown the relative contribution of agriculture to the total economy has decreased due to growth in other sectors. The farm prices have not changed significantly over many years while costs for energy, machinery, and land have generally increased. The combination of these factors has generally narrowed the profit margin and the highest productivity will no longer ensure the …

Nutrient Concentrations At Baseflow Conditions In The Upper White River Basin, Southwest Missouri And Northwest Arkansas, Gopala G. Borchelt

Graduate Theses/Dissertations

The Upper White River Basin (UWRB) is becoming increasingly vulnerable to water quality degradation from urban/population growth and increased agricultural production. This study examines the relationships among nutrient levels, water chemistry and watershed characteristics of 19 watersheds in the UWRB. Water samples were collected during baseflow conditions each month for one year at USGS continuous-flow gage stations. Watershed characteristics evaluated were land use, geology, drainage area, flow discharge, and wastewater treatment plant discharge (WTP). Measured chemical water quality indicators include total nitrogen (TN), total phosphorus (TP), specific conductivity, turbidity, pH and dissolved oxygen. Rapidly expanding urban areas are associated with …

Assessment Of Atrazine In A Rural Water Source: Rough River Lake, Kentucky, Scotty Sharp

Masters Theses & Specialist Projects

Atrazine [2-chloro- 4-(ethylamino)-6-(isopropylamino)-l,3,5-triazine], a widely used herbicide in US corn production, impacts quality of drinking water for many rural water supply systems. Four systems at Rough River Lake, Kentucky, have had high levels of atrazine in raw water and in some cases finished water that have exceeded the legal limit of 3 parts per billion (ppb). The Rough River Lake watershed is 1,700-km2, much of which is located in limestone karst. A hypothesis was developed stating that there would be higher concentrations of atrazine in the northeast section of the Rough River Watershed, located in Hardin County, due to the …

Modeling Soil Erosion In The Upper Green River, Ky, Narcisa Pricope

Masters Theses & Specialist Projects

Off-site soil erosion has tremendous impacts on the present state of most river systems throughout the United States, contributing sediments to channels mainly as nonpoint pollution resulting from land-use and agricultural practices and leading to sedimentation downstream and downwind, a decrease in the transport capacity of streams, increase in the risk of flooding, filling reservoirs, and eutrophication. A primary focus in examining the problems associated with soil erosion arid ultimately in proposing control measures should be on identifying the sources of the sediment. Therefore, a model that would be able to assess soil erosion needs to start by identifying the …

On The Spatial Nature Of The Groundwater Pumping Externality, Nicholas Brozovic, David L. Sunding, David Zilberman

Daugherty Water for Food Global Institute: Faculty Publications

Most existing economic analyses of optimal groundwater management use single-cell aquifer models, which assume that an aquifer responds uniformly and instantly to ground- water pumping. This paper demonstrates how spatially explicit aquifer response equations from the water resources engineering literature may be embedded in a general economic framework. Calibration of our theoretical model to published economic studies of spe- cific aquifers demonstrates that, by averaging basin drawdown across the entire resource, existing studies generally understate the magnitude of the groundwater pumping external- ity relative to spatially explicit models. For the aquifers studied, the drawdown predicted by single- cell models may …

Hydrological Effects And Groundwater Fluctuations In Interdunal Environments In The Nebraska Sandhills, David Gosselin, Venkataramana Sridhar, F. Edwin Harvey, James Goeke

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Nine years of groundwater monitoring data has documented the important influence that topographic relief and location in the groundwater flow system have on the hydrologic function of interdunal valleys. The western "wet" valley at the Gudmundsen Sandhills Laboratory in central Nebraska, which is a net discharge area, is more strongly buffered from the effects of annual-scale climatic variability than the eastern "dry" valley. The east valley is generally an area of net recharge and as such is more responsive to climatic variability. This study employed a simple water balance approach to estimate evapotranspiration (ET) from water level measurements in the …

Optimal Management Of Groundwater Over Space And Time, Nicholas Brozovic, David L. Sunding, David Zilberman

Daugherty Water for Food Global Institute: Faculty Publications

For nearly half a century, groundwater has been portrayed in the economic literature as a typical common property resource. Numerous studies of groundwater extraction have analyzed the externalities imposed by users on each other. A large body of work offers clear prescriptions in the form of optimal policy instruments, and a similarly large body of work advocates the needlessness of any centralized intervention. Yet existing theoretical models of groundwater extraction implicitly make two strong assumptions about the underlying behavior of the resource. First, the spatial distribution of resource users is assumed to be irrelevant. Second, path-independence of the resource is …

Promoting Low Impact Development In Your Community, New England Environmental Finance Center

Planning

Low Impact Development (LID) is an approach to stormwater management and site development that is gaining popularity throughout the country. Its attractiveness lies in its potential to lessen off-site stormwater impacts, reduce costs to municipalities and developers, and promote development that is “softer on the land” compared with typical traditional development. The approach, which is applicable to residential, commercial and industrial projects, and in urban, suburban and rural settings, often is linked with efforts by governments and citizens to foster more sustainable communities.

Assessing Water-Supply Potential Of Abandoned Underground Coal Mines In Eastern Kentucky, James S. Dinger, Dennis H. Cumbie, Bart Davidson

Report of Investigations--KGS

Use of water in abandoned underground coal mines for municipal, industrial, agricultural, or domestic water supplies is dependent upon the water quantity and quality. For either of these factors, the requirements of the user will play a role in what water quantity or quality is acceptable. This report provides analysis of field-derived water-quality and -quantity characteristics for six abandoned underground coal mines in the Eastern Kentucky Coal Field. In addition, some ancillary data from State regulatory agencies were used to help characterize water quality coming from the mines.

This study demonstrates that water quality in abandoned deep mines can be …
