Estimated Area Of Impervious Parking Surfaces And The Potential Groundwater Recharge Increase Through Permeable Pavement Retrofit In The Chino Basin, Zablon Afera Adane

Theses Digitization Project

California recently declared a state of emergency over drought followiing three years of below average rain and snowfall. There is a consensus among many involved in water supply in California for finding new sources of water, conservation, and increasing recharge to replenish the groundwater with surface water that would have been lost to run off. This study investigates the amount of stormwater that could potentially be reinvested as groundwater recharge by simply transforming selected impermeable parking lots of the commercial, industrial, and institutional sectors into pervious pavement that allow water to infiltrate rather than be lost as urban runoff.

Impact Of The Farmington Bay Eutrophication Plume On The Plankton Ecology Of Gilbert Bay, Great Salt Lake, Joe Crawford, Erin Fleming, Ashton Montrone, Meagan Wilcox, Jaclyn Wight

Watershed Sciences Student Research

Farmington Bay in the Great Salt Lake is hypereutrophic because of extreme nitrogen and phosphorus loading, largely from greater metropolitan Salt Lake City sewage effluents. Although this causes detrimental impacts within the bay, the influence of the outflow of its algal- and nutrient-rich waters into Gilbert Bay is largely unknown. To address this issue, students in the 2010 Aquatic Ecology Practicum course from Utah State University did a 13-km long transect analysis of trophic parameters from the causeway bridge separating the two bays, out into the pelagic zone of Gilbert Bay (Figure 1; Appendix A). On the September 30^{th …}

Correlation Between Normalized Ddifference Vvegetation Index And Malaria In A Subtropical Rain Forest Undergoing Rapid Anthropogenic Alteration, Nicole M. Wayant, Diego Maldonado, Antonieta Rojas De Arias, Blanca Cousino, Douglas G. Goodin

Center for Advanced Land Management Information Technologies: Publications

Time-series of coarse-resolution greenness values derived through remote sensing have been used as a surrogate environmental variable to help monitor and predict occurrences of a number of vector-borne and zoonotic diseases, including malaria. Often, relationships between a remotely-sensed index of greenness, e.g. the normalized difference vegetation index (NDVI), and disease occurrence are established using temporal correlation analysis. However, the strength of these correlations can vary depending on type and change of land cover during the period of record as well as inter-annual variations in the climate drivers (precipitation, temperature) that control the NDVI values. In this paper, the correlation between …

The Influence Of Nutrients And Physical Habitat In Regulating Algal Biomass In Agricultural Streams, Mark D. Munn, Jeffrey Frey, Anthony Tesoriero

United States Geological Survey: Water Reports and Publications

This study examined the relative influence of nutrients (nitrogen and phosphorus) and habitat on algal biomass in five agricultural regions of the United States. Sites were selected to capture a range of nutrient conditions, with 136 sites distributed over five study areas. Samples were collected in either 2003 or 2004, and analyzed for nutrients (nitrogen and phosphorous) and algal biomass (chlorophyll a). Chlorophyll a was measured in three types of samples, fine-grained benthic material (CHLFG), coarse-grained stable substrate as in rock or wood (CHLCG), and water column (CHLS). Stream and riparian habitat were characterized at each site. TP ranged from …

The Index Of Biological Integrity And The Bootstrap: Can Random Sampling Error Affect Stream Impairment Decisions?, Christine L. Dolph, Aleksey Y. Sheshukov, Christopher J. Chizinski, Bruce Vondracek, Bruce N. Wilson

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Multimetric indices, such as the Index of Biological Integrity (IBI), are increasingly used bymanagement agencies to determine whether surface water quality is impaired. However, important questions about the variability of these indices have not been thoroughly addressed in the scientific literature. In this study, we used a bootstrap approach to quantify variability associated with fish IBIs developed for streams in two Minnesota river basins. We further placed this variability into a management context by comparing it to impairment thresholds currently used in water quality determinations for Minnesota streams. We found that 95% confidence intervals ranged as high as 40 points …

The Impact Of Rare Taxa On A Fish Index Of Biotic Integrity, Haibo Wan, Christopher J. Chizinski, Christine L. Dolph, Bruce Vondracek, Bruce N. Wilson

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

The index of biotic integrity (IBI) is a commonly used bioassessment tool that integrates abundance and richness measures to assess water quality. In developing IBIs that are both responsive to human disturbance and resistant to natural variability and sampling error, water managersmust decide how to weigh information about rare and abundant taxa, which in turn requires an understanding of the sensitivity of indices to rare taxa. Herein, we investigated the influence of rare fish taxa (within the lower 5% of rank abundance curves) on IBI metric and total scores for stream sites in two of Minnesota’smajor river basins, the St. …

Western Australian Resource Condition Monitoring Projects 2007-2009, Ceidwen Pengelly, 2010

All other publications

Monitoring the status and trends of our natural resources is the only way we can assess whether the actions that have been implemented are making a difference. The impetus for this resource condition monitoring program (RCM) was the recognition that our monitoring networks, baseline data and data management systems were inadequate to enable quantitative reporting to government, and the community, on the difference their investments in natural resource management were making. It was considered that making a significant investment in raising our ability to report would be a long-lasting legacy of value to the state.

The Impacts Of Land Use And Development Patterns On Water Quality Of The Belgrade Lakes, Ian M. Mccullough

Honors Theses

The purpose of this study was to assess the impacts of patterns of land use and development on water quality in the Belgrade Lakes on a regional scale. Regional research and cooperation could identify key areas in the watershed where development or changing land use could have the greatest negative influences on lake water quality. Past work has centered on water chemistry, nutrient dynamics, development and economic factors but there has been no comprehensive analysis of land use and development history for the entire Belgrade Lakes Region. The Belgrade Lakes are a chain of 7 lakes in central Maine connected …

Sediment Phosphorus Flux In Beaver Lake In Northwest Arkansas, Taraf Abu Hamdan, Thad Scott, Duane Wolf, Brian E. Haggard

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Internal phosphorus (P) loading may influence primary production in lakes, but the influence of sediment-derived P has not been well studied in Beaver Lake of Northwest Arkansas. Soluble reactive phosphorus (SRP), dissolved organic P (DOP), and total dissolved P (TDP) sediment-water fluxes were determined using intact sediment cores collected from deepwater environments in the riverine, transition zone, and lacustrine zones of Beaver Lake. The SRP, DOP, and TDP fluxes were also estimated from cores collected from shallow locations in the transition zone. There was a net positive SRP (0.001 – 0.005 µg P cm-2 h-1), DOP (0.005 – 0.01 µg …

Assessment Of Total Organic Carbon Concentrations In Two Streams Of Northwest Arkansas: Town Branch And Brush Creek, Abigail N. Washispack, Jason A. Mcginnis, Brian E. Haggard

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Within a stream, changes in flow rate and local environment can affect the total organic content (TOC) concentrations in the stream water and TOC delivery downstream to water supply reservoirs. Disinfection by-products (DBPs) result from various chemical reactions between chlorine, bromine, and organic carbon in raw water during the drinking water treatment process; DBPs are potential carcinogens and are regulated by the U.S. Environmental Protection Agency. In this project, we measured the TOC concentrations in two streams in the Beaver Lake Watershed: Town Branch and Brush Creek. We then compared TOC concentrations between the two streams and to that observed …

Riparian Conundra, David Weaver

Conference papers and presentations

Riparian vegetation is established or restored on the basis that it physically filters and traps hillslope derived particulate nutrients in surface runoff. Whilst many studies support this conventional model of riparian function, few test this models embedded assumptions. The assumptions are that catchments are surface runoff dominated, that most surface derived nutrients are transported in particulate form, and that riparian management targets locations that will result in the greatest change in water quality. This paper reviews studies in south west Western Australia that challenge these assumptions. Plots measuring leaching and runoff of nutrients showed that 20 times more water and …

A Real Time Optical Biosensor Assay For Amoxicillin And Other Β-Lactams In Water Samples, Israel M. Scott, Lewis J. Kraft, Jonathan D. Parker, Kathryn Daniel, Sarah Kustick, Diana Kennen, Jonathan L. Mcmurry

Faculty Articles

Antibiotic contamination of drinking water and sewage is a matter of environmental and public health concern. Traditionally, ELISA or HPLC methods have been used to detect and measure antibiotic contamination. By applying an optical biosensing method, biolayer inteferometry (BLI), we have developed a kinetic competition binding assay capable of quantitating less than lppm (~33 μM) amoxicillin. Similar to surface plasmon resonance, BLI senses changes that occur upon binding of one molecule to another near a surface to measure association and dissociation. Immobilized amoxicillin was used to screen for binding against an analyte solution of anti-amoxicillin equilibrated with amoxicillin-containing water samples, …

Water Quality Study Of Paya Indah Wetlands., Ridzuan Ahmad

Student Works (2010-2019)

A study had been carried out on Paya Indah Wetlands’ water quality from December 2006 to February 2007. This was to determine the status of water quality. From the analysis on Water Quality Index (WQI) at 15 sampling stations, it was observed that WQI of Paya Indah at most stations were within polluted range. From the comparative study made on WQI at major lakes and canals between year 1996 and 2006/2007, it was observed that Canal C2 and Canal C4 show slight improvement (48.7 – 50.0 and 41.5 – 59.2 respectively). However, major lakes of Paya Indah shows decrease of …

Hydrogeochemistry Of Caves Drip Water At Selected Caves In Peninsular Malaysia., Nor Bakhiah Baharim

Student Works (2010-2019)

This preliminary study represents the study on hydrogeochemical of caves drip water throughout Peninsular Malaysia. All samples were analysed for pH, Total Dissolved Solid (TDS), Dissolved Oxygen (DO), Conductivity, cation and anion. Despite local hydrological and geological differences among sampling sites, the monitoring revealed significant synchronous intersite variations that related to rainfall variation and control the volume of water input. The constant hydraulic pressure is expected in karst system as a result of moist condition of tropical region and rainfall throughout the year. Drip sites were classified into to two classifications which are seepages flow and seasonal flow. A simplified …

Land Use And Water Supply, Susan Kelly, Joanne Hilton

Water Matters!

As New Mexico grows and develops, there is a continuing increase in water demand and the need to provide additional supplies. Recent studies estimate the current population of the State to be about two million people, and the population is expected to grow to approximately 3,400,000 by 2050. Regional water plans project water demands for 16 regions within New Mexico. The total projected new water use associated with population growth—the public water supply and associated commercial sectors, exclusive of agriculture, mining, or other industries—ranges from 280,000 to 380,000 acre-feet per year of new water supply needed in the next 40 …

National Drought Mitigation Center: Faculty Publications

Increasing surface temperatures and climatic variability associated with global climate change are expected to produce more frequent and intense heat waves and droughts in many parts of the world. Our goal was to elucidate the fundamental, but poorly understood, effects of these extreme weather events on avian communities across the conterminous United States. Specifically, we explored: (1) the effects of timing and duration of heat and drought events, (2) the effects of jointly occurring drought and heat waves relative to these events occurring in isolation, and (3) how effects vary among functional groups related to nest location and migratory habit, …

A Methodology To Estimate The Future Extent Of Dryland Salinity In The Southwest Of Western Australia, Peter Caccetta, Robert Dunne, Richard J. George, Don J. Mcfarlane

Natural Resources Research Articles

In the southwestern agricultural region of Western Australia, the clearing of the original perennial vegetation for annual vegetation-based dryland agriculture has lead to rising saline groundwater levels. This has had effects such as reduced productivity of agricultural land, death of native vegetation, reduced stream water quality and infrastructure damage. These effects have been observed at many locations within the 18 million ha of cleared land. This has lead to efforts to quantify, in a spatially explicit way, the historical and likely future extent of the area affected, with the view to informing management decisions. This study was conducted to determine …

Where New Meanings Spring: The Relationship Between Indigenous Cultural Meanings For Freshwater Springs And Management Practices: Analysis Of Stories From Kalbarri, Western Australia, Tamara Lee Murdock

Theses : Honours

While Indigenous peoples' practices have been acknowledged to change and evolve, whether Indigenous cultural meanings invested in a specific place also change and/or evolve over time, and the affect these changes may have on land and water practices has generally been ignored. This study explores the relationship between Indigenous cultural meanings and land and water stewardship practices, and whether these change over time. A qualitative research design was employed in this study to emphasise the complex and dynamic nature of language and the relationship between people, culture and nature. This study utilised interviews collected from traditional Indigenous people concerning stories …

Effect Of Low And High- Kinetic Energy Wetting On Quality Of Sediment Produced By Interrill Erosion, Eduardo Abel Rienzi

University of Kentucky Doctoral Dissertations

Raindrop kinetic energy and sheet flow can disintegrate aggregates during interrill erosion, a process responsible for non point source pollution. Also, the dissolution process during aggregate wetting can affect interrill erosion. These factors can be responsible for changes in particle size distribution in the sediment, especially when different tillage systems are compared. The effect of soil tillage and management on soil properties is not uniform, which determine a wide range of runoff and sediment delivery rate. Variety in these rates can be associated with pore functions and their interactions with aggregate stability. One of the objectives of this study was …
