The Municipal Climate Action Plan was written in partnership with Clean Air – Cool Planet and Portland officials, and acknowledges under Recommendation #2 that an employee energy efficiency program would provide significant positive impact on the City’s reduction of greenhouse gas emissions. Best practices from three cities show that focus on the greening of City Hall is critical in developing a program that promotes partnerships, community …

Preserving Assets In At-Risk Municipalities: Financial Strategies For Climate Change Adaptation, New England Environmental Finance Center

Climate Change

A large share of America's population, businesses and economic activity now occurs in coastal areas. At the same time, during this century many coastal communities are likely to be severely impacted by sea level rise and increased storm surge and tidal flooding.

“What to do” about this vulnerability is the subject of this brief. It is intended to help municipalities identify courses of action and steps they might take toward increasing their resilience, especially regarding financial resources that will need to be allocated toward the various strategies identified.

Demonstrating Sustainable Farm Management Systems. Final Report For Rcg05-Ord13, Tara Slaven, Francis Bright, Jodie Hawley, Joe Sherrard

Natural resources research reports

The Ord River Irrigation Area (ORIA) has a 'flow through' irrigation system. That is, irrigation water is diverted from Lake Kununurra and any waste water from the irrigation system and farms flows directly back into the river downstream. This means that any sediment, nutrient or chemicals in tailwater from farms flows straight into the river.

The Ord Land and Water Management Plan 2000 specifies goals to improve surface water quality. The goals are to reduce the load of chemical and nutrient contamination and sediment in tailwater by 40 per cent.

The aim of this project was to develop and demonstrate …

The History Of The Unl Water Center From 1964, Water Center, School Of Natural Resources

Nebraska Water Center: Administrative Materials

Water is an integral part of Nebraska’s economy and well being in a state that depends on an adequate supply for all uses, including agricultural, municipal, industrial, recreational and wildlife habitat.

Nebraska is fortunate with regard to its water supply, having tremendous groundwater reserves which are estimated to be in excess of two billion acrefeet (an acre-foot being enough water to cover one acre of land with a foot of water, or approximately 325,000 gallons), combined with an estimated annual precipitation of 86 million acre-feet and annual average surface water inflows of 1.7 million acre-feet, give the state adequate supplies …

Massive Spatiotemporal Watershed Hydrological Storm Event Response Model (Mhserm) With Time-Lapsed Nexrad Radar Feed, Changqing Song

Civil & Environmental Engineering Theses & Dissertations

Correctly and efficiently estimating hydrological responses corresponding to a specific storm event at the streams in a watershed is the main goal of any sound water resource management strategy. Methods for calculating a stream flow hydrograph at the selected streams typically require a great deal of spatial and temporal watershed data such as geomorphological data, soil survey, landcover, precipitation data, and stream network information to name a few. However, extracting and preprocessing such data for estimation and analysis is a hugely time-consuming task, especially for a watershed with hundreds of streams and lakes and complicated landcover and soil characteristics. To …

Coupling The Hydrodynamic And Water Quality Model Ce-Qual-W2 With A Multi-Trophic Fish Bio-Energetics Model For Lake Roosevelt, Washington, Michael Lee Mckillip

Dissertations and Theses

Grand Coulee Dam created Franklin D. Roosevelt Lake as part of the Columbia Basin Project. Located in northeastern Washington State, the Project provides economically important hydropower (19 billion kilowatt hours per year), irrigation (225,000 ha), flood control, and sport fishing ($5 to 20 million annually). A good system understanding aids in balancing these beneficial uses for the 230 km long reservoir. The reservoir's atypical 45-day mean residence time is much shorter than a typical lake, and much longer than for a riverine dam. The spring freshet requires drawdowns of 15 to 20 m for flood control—the driving characteristic of reservoir …

Source Identification Of Ammonia Inputs To The Wastewater Treatment Holding Pond At International Paper Franklin Mill, Melissa Riddick Wolford

Civil & Environmental Engineering Theses & Dissertations

While nitrogen is an essential nutrient in aquatic systems, elevated levels of nitrogen can be fatal to many aquatic organisms including fish and other organisms that are in the river. Elevated levels of ammonia have been recently (2001-2002) detected in the water released from a wastewater treatment system holding pond at International Paper Franklin, Virginia and are a concern for the receiving system. The elevated ammonia concentrations observed in previous years were not observed in 2003, due likely to increased precipitation and the occurrence of a major hurricane (Hurricane Isabel) during the sampling period that may have influenced the observations. …

Evaluation Of Water Levevaluation Of Water Levels In Relation To The Design Of Coastal Structures In Tanzaniaels In Relation To The Design Of Coastal Structures In Tanzania, Alfonse Dubi

Tanzania Journal of Engineering and Technology (TJET)

Water levels on the coastline of Tanzania vary under the influence of meteorological conditions (winds and barometric pressure) and the East African Coastal Current, whose strength varies with the monsoon winds. Available tidal information is not enough to warrant statistical analysis for evaluating extreme water levels. The highest mean water springs occur at Bagamoyo and Pangani (3.93 m) and the lowest are found at Lindi (2.96 m). The highest astronomical tide is 3.7 m for Dar es Salaam and 4.6 m for Zanzibar, both of which occur during March/April and November. Measured highest water levels approach 4.80 m for Dar …

Fisheries Management Report No. 6 - Proceedings Of Marron Farming Open Day 2002, Greg B. Maguire

Fisheries Published Reports

The marron industry is of considerable importance to the Department of Fisheries, being one of the older aquaculture industries in Western Australia, and one that accounts for around half the aquaculture licence holders in the State. While it has not grown as quickly as many hoped in the past, in 2000/01, some 52.2 tonnes of marron were produced, worth $1.18 million at the farm gate.

It is regionally significant, particularly in the south-west, and depending on appropriate site selection, has considerable potential in other areas. Farms are distributed from near Geraldton to around Bremer Bay, with additional interest around Esperance. …

A Buffered Advection/Dispersion Lake Water Quality Transport Framework For Modeling Lake Gaston Pipeline Intake Water Withdrawal, Lloyd Ashton Gatling

Civil & Environmental Engineering Theses & Dissertations

Water quality response to reservoir water withdrawal is investigated in Pea Hill Arm of Lake Gaston, a non-tidal reservoir tributary, where the point of water withdrawal is in an upstream tributary and influences the direction of tributary flow causing longitudinal velocity null flow conditions to occur. The study also focuses on control of withdrawal rate and timing to optimize both quality of water remaining in the tributary and quantity of water that can be safely withdrawn.

Research was conducted assuming steady state conditions and later under spatial and temporal variability experienced in the reservoir with main lake pool elevation fluctuations …

Evaluation Of Soil Conservation Measures: A Case Study In Mbinga District, Ruvuma Region, Tanzania, S. Y. Thadei

Tanzania Journal of Engineering and Technology (TJET)

A study on soil conservation measures was conducted in two villages, Tukuzi and Mahenge, in Mbinga District, Ruvuma Region, Tanzania. The results showed that the ngoro farming system was effective in controlling soil erosion by water on both steep and gentle slopes. Sediments collected from ngoro had high concentrations of plant nutrients such as available phosphorus (P), total nitrogen (N), organic carbon (OC) and exchangeable bases. This was probably due to nutrients released from decomposed grass bundles buried in the soil. In preventing soil erosion, ngoro and bench terraces were equally effective, while contour ditches were as effective as ridges …

The purpose of the Chesapeake Bay Local Assistance Department (CBLAD) Calculation Procedures is to ensure that the development of constructed areas do not further exacerbate current problems of stormwater-induced eutrophication and downstream flooding. The methodology is …

Effects Of Temperature, Water Hardness, And Recirculation On Copper Corrosion, Brian R. Weiss

Electronic Theses and Dissertations

In previous work, the effects of water quality have been shown to influence the formation of scale from copper corrosion. A general understanding of the effects of water quality on copper corrosion have been difficult to obtain because of complex interactions of water quality variables on copper corrosion in different water supply systems. The objective of this study was to examine the effects of temperature and water hardness on copper corrosion occurring in a household water supply system. The effects of recirculation were also studied in concurrence with the above water quality parameters. Electrochemical corrosion testing and corrosion by -product …
