Relationships Between Stream Order And Management Priority: A Water Quality Case Study, David Weaver, Adrian Reed, John Grant

Conference papers and presentations

Seagrass, which once dominated the habitat of Oyster Harbour on the south coast of Western Australia has been replaced by macroalgae because of increased nutrient and sediment discharge from the rural dominated catchment. Total Phosphorus (TP), Total Nitrogen (TN), Suspended Sediment (SS) and Electrical Conductivity (EC) concentrations from a catchment – wide (168 sites), event-driven snapshot, water quality monitoring program conducted from 1994 to 1996, were analysed in relation to stream order and published survey data on riparian zone condition. This analysis was performed to examine relationships between stream order, riparian zone condition and water quality, and implications for the …

Burakin Focus Catchment Report, Mike Clarke

Natural resources published reports

The Burakin Focus Catchment Project was developed between farmers and Agriculture _ Western Australia. The project was designed to give farmers an understanding of the salinity processes occurring within the Catchment and suggestions on appropriate management.

Work began in the Catchment early in 1999 and was complete at the end of 2000. Intensive hydrological investigations formed the basis of the study, which was complemented by surface water control and revegetation strategies. Agronomic issues associated with sandplain soils were raised by the farmers at the initial meeting and this led to a soil survey to determine the pH status of the …

Farming Systems To Manage Salinity. Farmer Directed Research, Development And Extension. Research Results 2001, Richard Olive

Natural resources published reports

More and more of Western Australia's agnicultural lands are becoming saline. Currently it is estimated that about 18 milliion ha of land are affected to a greater or lesser degree by salinity causing production losses estimated at about $70 million a year.

Unless ways are found to halt and reverse the salinisation of land it is estimated that another 4.4 million ha could become saline over the next 50 years.

Grain growers and the Federal Government, through the Grains Research and Development Corporation (GRDC). are investing $12 4 million in R&D across Australia to develop productive solutions to the salinity …

An Evaluation Of Stream Flow Characteristics And Fecal Coliform Loads In Sayler's Creek Watershed, South Central Virginia, David Straton Gilbert

Theses & Honors Papers

The Sayler's Creek watershed is located within Prince Edward County, Nottoway, and Amelia Counties of the south central region of Virginia. The Sayler's Creek Watershed consists of two small creeks: Big Sayler's Creek and Little Sayler's Creek. The Environmental Protection Agency has Big Sayler's Creek listed as impaired and not Little Sayler's Creek. Based upon visual inspections of the Sayler's Creek watershed throughout the year, Little Sayler's Creek is inlpaired for fecal coliform instead of Big Sayler's Creek. Another hypothesis of this study is that fecal coliform levels are directly related to runoff from cattle ranches in the immediate floodplain …

Profiting From Adversity - Meeting The Challenge Of Salinity Through New Industry Development, Andrew Quinn, Tamara Law, Peter Rowe

Natural resources published reports

Salinity in the Wheatbelt of Western Australia is one of the most significant challenges facing the State's agricultural sector.

Efforts to manage the increasing effect of salt influenced and threatened farming land requires not only the implementation of new farming systems, but a new way of thinking and attitude to production more in tune with environmental and technological limitations.

While past environment lobby pressures have significantly focused on other production activities such as mining and forestry, the future is likely to see increased community interest in agricultural production systems.

Consumers World wide are becoming more environmentally sensitive, with global media …

Remote Sensing And Geographic Information Systems For Decision Analysis In Public Resource Administration: Case Study In A Southwestern Watershed, William G. Kepner

UNLV Theses, Dissertations, Professional Papers, and Capstones

Alternative futures analysis is a scenario-based approach to regional land planning that attempts to synthesize existing scientific information in a format useful to community decision makers. Typically, this approach attempts to investigate the impacts of several alternative sets of choices preferred by representative stakeholder groups relative to selected environmental or economical endpoints. Potential impacts from each of the scenarios are compared to current conditions of the region in terms of a set of processes that are modeled within a geographic information system. Future conditions are generally examined from the perspective of a recent baseline condition (versus empirically determined using a …

Dynamic Fluvial Systems And Gravel Progradation In The Himalayan Foreland, Nicholas Brozovic, Douglas W. Burbank

Daugherty Water for Food Global Institute: Faculty Publications

Although the large-scale stratigraphy of many terrestrial foreland basins is punctuated by major episodes of gravel progradation, the relationships of such facies to hinterland tectonism and climate change are often unclear. Structural reentrants provide windows into older and more proximal parts of the foreland than are usually exposed, and thus provide key insights to earlier phases of foreland evolution. Our magnetostratigraphic studies show that, although the major lithofacies preserved within the Himachal Pradesh structural reentrant in northwestern India resemble Neogene facies in Pakistan, they have a much greater temporal and spatial variability. From 11.5 to 7 Ma, major facies boundaries …

The water quality of this system is of considerable interest because of its status as an environmental, recreational, and therefore, economic resource. The broad range of optical conditions present in the lakes and the wealth of literature on the system make it an ideal environment for water quality remote sensing research. The goal of this research was to survey the water quality of the Iowa Great Lakes via remote sensing, evaluate different predictive algorithms, and map the distribution of …

Intermediate Rings Between A Local Domain And Its Completion, William Heinzer, Christel Rotthaus, Sylvia Wiegand

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

We consider the structure of certain intermediate domains between a local Noetherian domain Rand an ideal-adic completion R* of R that arise as the intersection of R* with a field containing R. In the case where the intersection domain A can be expressed as a directed union of localized polynomial extension rings of R, the computation of A is easier. We examine conditions for this to happen. We also present examples to motivate and illustrate the concepts considered.

Water Quality In East Pond: Factors Contributing To Algal Blooms And Strategies For Remediation, Problems In Environmental Science Course (Biology 493), Colby College, Colby Environmental Assessment Team, Colby College

Colby College Watershed Study: East and North Ponds (2011, 1999, 1996, 1991)

Human activity within the watershed can greatly accelerate the eutrophication process by increasing the rate at which nutrients such as phosphorus and nitrogen enter the lake (Fernandez et al. 1992). Increased nutrient loading causes dramatic increases in algal populations resulting in algal blooms. Many New England lakes develop a greenish tint because of algal blooms during early summer or early fall (Smith, 1992). Populations of bacteria which feed on organic material rise because of increased food supply. Bacterial activity decreases the level of dissolved oxygen in the lake (Henderson-Seller and Markland, 1987). This process has occurred in East Pond and …

A Spatial And Temporal Analysis Of Riparian Vegetation Along Satus Creek On The Yakama Indian Reservation, Kathryn Gellenbeck

All Master's Theses

Satus Creek provides critical habitat for the Yakima River Basin steelhead. A diverse community of riparian vegetation is important for healthy fish habitat; vegetation changes can affect shade, cover, channel structure, water quality, and food availability. The purpose of this thesis is to analyze and illustrate riparian vegetation change, both temporally and spatially, along three separate reaches of Satus Creek. A Geographic Information Systems approach was applied to assess the vegetation change by comparing plant species composition and density on 1949 and 1995 aerial photographs. The GIS approach allowed patterns and trends in the vegetation to be identified. In less …

Salinity And Hydrology Of The Fence Road Catchment : A Focus Catchment Of The Blackwood Basin, Ben Whitfield

Resource management technical reports

It is the clearing of native vegetation and replacement with lower water-use annual crops and pastures that is responsible for the developing salinity problem. Traditional farming practices have led to increased recharge to the groundwater systems resulting in increased storage and/or greater areas or rates of discharge. Groundwater monitoring has revealed variable rates of rise throughout the Fence Road catchment, from static to 0.6 metres per year, in a period of average to below average rainfall.

Monitoring The 1996 Drought Using The Standardized Precipitation Index, Michael J. Hayes, Mark D. Svoboda, Donald A. Wilhite, Olga V. Vanyarkho

National Drought Mitigation Center: Faculty Publications

Droughts are difficult to detect and monitor. Drought indices, most commonly the Palmer Drought Severity Index (PDSI), have been used with limited success as operational drought monitoring tools and triggers for policy responses. Recently, a new index, the Standardized Precipitation Index (SPI), was developed to improve drought detection and monitoring capabilities. The SPI has several characteristics that are an improvement over previous indices, including its simplicity and temporal flexibility, that allow its application for water resources on all timescales. In this article, the 1996 drought in the southern plains and southwestern United States is examined using the SPI. A series …
