Palaeoecology: A Tool To Improve The Management Of Australian Estuaries, Krystyna M. Saunders, Kathryn H. Taffs

Dr Kathryn H Taffs

Addressing environmental problems in estuaries is a worldwide problem. Establishing benchmarks and targets for management is critical, whether the aim is conservation, restoration or ‘sustainable wise use’. Palaeoecological techniques have rapidly improved during the past decade, particularly with advances in methods that allow high resolution quantitative assessments of environmental change, allowing pre-impact conditions, the rate, extent and direction of change, and range of natural variability to be determined. Australian estuarine ecosystems are qualitatively different to the often more well-studied estuaries in North America and Europe, which means site-specific studies of Australian estuaries are needed to inform management. While a potentially …

White River Forum Ii: Second Annual Meeting Of The White River Forum, John Havel, Kenneth Steele

Technical Reports

This second annual meeting of the White River Forum is proof of widespread interest in the water quality of the Upper White River watershed. The participation of numerous elected officials, state and federal agencies, universities, businesses, and local citizens indicates that interest in understanding policy issues crosses political boundaries and occupations.

Agenda: Best Practices For Community And Environmental Protection, University Of Colorado Boulder. Natural Resources Law Center. Intermountain Oil And Gas Bmp Project, Colorado. Oil And Gas Conservation Commission

Best Practices for Community and Environmental Protection (October 14)

The first Intermountain BMP Project workshop, sponsored by the Natural Resources Law Center and the Colorado Oil and Gas Conservation Commission, was held in Rifle, Colorado on October 14, 2009 at the Garfield County Fairground for over 170 participants.

Speakers from Federal, state and local governments, the community, industry and environmental consultants, and conservation groups focused presentations and discussion on a greater understanding of what Best Management Practices (BMPs) are appropriate to the western slope of Colorado and how they are integrated into developments.

Water Quality Sampling, Analysis And Annual Load Determinations For Nutrients And Solids On The Ballard Creek, 2008, L.B. Massey, L.W. Cash, B.E. Haggard

Technical Reports

The Arkansas Water Resources Center monitored water quality at Ballard Creek at the Washington County Road 76 Bridge in northwest Arkansas during base flow and storm events from July 1, 2008 through June 30, 2009. Water samples were collected manually or with an auto-sampler and analyzed for nitrate-nitrogen, ammonia-nitrogen, total nitrogen, total phosphorus, soluble reactive phosphorus, sulfate, chloride and total suspended solids. Instantaneous stage and discharge were recorded at the site; total annual discharge was 55,800,000 m³ , with 27% attributed to base flow and 73% attributed to storm flow. Loads were estimated using the mid-interval integration approach using continuous …

Water Quality Sampling, Analysis And Annual Load Determinations For The Illinois River At Arkansas Highway 59 Bridge, 2008, L.B. Massey, L.W. Cash, B.E. Haggard

Technical Reports

The Arkansas Water Resources Center monitored water quality at the Illinois River at the Arkansas Highway 59 Bridge, just upstream from the Arkansas-Oklahoma state border during base flow and storm events from July 1, 2008 through June 30, 2009. Water samples were collected manually or with an auto-sampler and analyzed for nitrate-nitrogen, ammonia-nitrogen, total nitrogen, total phosphorus, soluble reactive phosphorus, sulfate, chloride and total suspended solids. The U.S. Geological Survey recorded instantaneous stage and discharge at the site, total annual discharge was 1,010,000,000 m³ , with 37% attributed to base flow and 63% attributed to storm flow. Loads were estimated …

Frequency Distributions Of Median Nutrient And Chlorophyll Concentrations Across The Red River Basin, 1996-2006, S.D. Longing, B.E. Haggard

Technical Reports

Acquisition and compilation of water quality data for a ten year time period (1996 – 2006) from 589 stream and river stations was conducted to support nutrient criteria development for the multi–state Red River Basin shared by Arkansas, Louisiana, New Mexico, Oklahoma and Texas, USA. Twenty–three water quality parameters were collected from five data sources (USGS, ADEQ, LDEQ, OCC, OWRB, and TCEQ) and an additional 13 parameters were acquired from at least one source. Data for the primary biological parameter of interest, chlorophyll a, was sparse and available from only two sources. Following compilation of data, medians were calculated for …

Water Quality Variability In A Bioswell And Concrete Drainage Pipe, Southwest Lincoln, Nebraska, Jessica Shortino

Department of Environmental Studies: Undergraduate Student Theses

Abstract The goal of this project is to evaluate the effectiveness of bioswells in protecting water quality from urban runoff. The hypothesis tested in this project is that water in bioswells improves water quality. Water quality in both a bioswell and an underground concrete lined ditch, both containing ground and surface water, were tested for certain water quality parameters. These parameters consisted of: Dissolved Oxygen, pH, water temperature, weather temperature, Total Dissolved Solids, Specific Conductivity, Alkalinity, Total Dissolved Carbon, Chemical Oxygen Demand, and depth and width of the sampling site. An additional contaminant that was looked at was motor oil. …

Monitoring Water Quality On Tributary Inflows To Lake Mead And On A Transect Of The Overton Arm, Jorge Arufe, Robert Burrows

Lake Mead Science Symposium

The USGS, in cooperation with the NPS and BOR (Bureau of Reclamation), is collecting water quality data to determine the temporal changes and spatial distributions of natural and anthropogenic compounds entering the Overton Arm of Lake Mead. These efforts and others already underway on the lake by BOR, USGS, and SNWA will aid in the development of a reservoir model of the lake. The effects of the flood flows on the water quality of the Overton Arm are largely unknown and necessary for model development and verification.

Water quality physical parameters are continuously monitored near the mouth of the Virgin …

History Of Contaminant Inputs Into Lake Mead Derived From Sediment Cores, Michael R. Rosen, Peter C. Van Metre, David Alvarez, Kathy R. Echols, Steven L. Goodbred

Lake Mead Science Symposium

Assessing the changes in contaminant inputs (both organic and inorganic) over time is important in determining sources and sinks of these inputs. Variations in contaminant input were assessed in four sediment cores taken in 1998 from three different parts of Lake Mead (two from Las Vegas Bay and one from Overton Arm and Virgin Basin). Sediments were analyzed for major and trace elements, radionuclides, and organic compounds. Anthropogenic contaminant concentrations are greatest in Las Vegas Bay reflecting inputs from the Las Vegas urban area, although concentrations are low compared to sediment quality guidelines and to other USA lakes. One exception …

Creating Lakes From Open Pit Mines: Processes And Considerations, Emphasis On Northern Environments, Christopher H. Gammons, Les N. Harris, James M. Castro, Peter A. Cott, Bruce W. Hanna

Geological Engineering

Creating Lakes from Open Pit Mines: Processes and Considerations, Emphasis on Northern Environments. This document summarizes the literature of mining pit lakes (through 2007), with a particular focus on issues that are likely to be of special relevance to the creation and management of pit lakes in northern climates. Pit lakes are simply waterbodies formed by filling the open pit left upon the completion of mining operations with water. Like natural lakes, mining pit lakes display a huge diversity in each of these subject areas. However, pit lakes are young and therefore are typically in a non-equilibrium state with respect …
