The Bay Study Group was created by the City of Tampa in 1976 to monitor the effects of pollution abatement that occurred in Hillsborough Bay when the city’s wastewater treatment plant was upgraded from primary to advanced treatment in 1979. The Bay Study Group documented a remarkable restoration of water quality parameters and biological indicators in Hillsborough Bay from the mid 1980s until 2009, when it was disbanded. This zip Geodatabase file contains the aerial photos for the year 1988.


Water Quality 1986 - 1987 Hillsborough County, Florida, Hillsborough County Environmental Protection Commission Jan 1988

Water Quality 1986 - 1987 Hillsborough County, Florida, Hillsborough County Environmental Protection Commission

Reports

The Hillsborough County Environmental Protection Act charges the Environmental Protection commission with the function of establishing, operating and maintaining a continuous program for monitoring water pollution. A county-wide water quality surveillance network has been designed to enable the staff to determine compliance with the Act and to determine whether the level of water pollution is increasing or decreasing throughout the county.

These data, obtained during 1972-1987 may provide useful background for eventual development, revision _ and enforcement of regulations, standard effluent limitation plans, or programs established under the Federal Water Pollution Control Act of 1972.

Preliminary Groundwater And Salinity Investigations In The Eastern Wheatbelt 2. Merredin Catchment, Richard J. George Dr, P W C Frantom Jan 1988

Preliminary Groundwater And Salinity Investigations In The Eastern Wheatbelt 2. Merredin Catchment, Richard J. George Dr, P W C Frantom

Resource management technical reports

Saline groundwater occurs within twelve metres of the surface throughout the valley of the Merredin catchment. Saline groundwater occurs within deep sediments deposited in the valley and deeply-weathered bedrock materials. Rapid groundwater recharge appears to be taking place in sandy-textured soils high in the landscape and directly into the Cainozoic sediments in the valley floor. Water-tables are rising at approximately ten centimetres each year in the upper catchment area.

The Use Of Permeability, Conductivity, Conductance And Resistance In The Description Of Water Movement In Soils And Plants, H Borg Jan 1988

The Use Of Permeability, Conductivity, Conductance And Resistance In The Description Of Water Movement In Soils And Plants, H Borg

Resource management technical reports

Permeability, conductivity, conductance and resistance are important parameters in the description of water movement in soils and plants. These terms are related, but not synonymous. Permeability is only a function of the flow pathgeometry of the medium, while conductivity also depends on the fluid involved. Conductance, in addition, takes the size of the medium into account. Resistance is simply the inverse ofconductance. By applying the definition of resistance, it isshown that Darcy's law and Ohm's law are equivalent. Conductance and resistance relate volume flow rate to a potential difference, but to relate volume flux (volume flowrate per unit area) to …

Climatic Change In Western Australia, M A. Frahmand, R A. Nulsen Jan 1988

Climatic Change In Western Australia, M A. Frahmand, R A. Nulsen

Books & book chapters

The greenhouse effect is now an established scientific fact. Evidence published in the US and Australia in 1987 leaves little room for doubt. Carbon dioxide sent into the air whenever fossil fuels are burnt traps reflected heat from the Earth's surface - just as a greenhouse traps heat on a summer's day.

The uncertainties currently present in any prediction of future regional climate are very large. This paper presents a synopsis of current literature related to the future climate of Western Australia.


Population Status Of Five Potentially Threatened Vascular Plants From Coastal Plain Tidal Rivers In Virginia, Carl Hershner, James Perry Jan 1988

Population Status Of Five Potentially Threatened Vascular Plants From Coastal Plain Tidal Rivers In Virginia, Carl Hershner, James Perry

Reports

Work is underway to clarify the population status of Virginia's biota that have been considered rare, endangered, or of an unknown population status by earlier scientists (Porter, 1979). The purpose of the current study was to investigate the population status and areal distribution of five of these plant species found on the tidal rivers of the Coasta1 Plain in Virginia. Although only a small portion of a much larger effort, it is hoped that this work will help fill some of the gaps that exist in our data base on these species. Furthermore, it is hoped that the following information …

Oyster Spatfall In Virginia Rivers: 1987 Annual Summary, James Whitcomb Dec 1987

Oyster Spatfall In Virginia Rivers: 1987 Annual Summary, James Whitcomb

Reports

The Virginia Institute of Marine Science (VIMS) conducts weekly surveys from June through early October to obtain oyster spatfall information. Spat counts are made on oyster shells strung on wire and suspended from stakes on public and private beds. The number of spat on shells is counted each week of the spawning season to determine the potential of a particular area for receiving a strike and to predict the most likely period the strikes will occur.

Wastewater Management Alternatives For The Salt Pond Region Of Westerly, Rhode Island (With Special Emphasis On The Winnapaug Pond Watershed), John R. King Dec 1987

Wastewater Management Alternatives For The Salt Pond Region Of Westerly, Rhode Island (With Special Emphasis On The Winnapaug Pond Watershed), John R. King

Marine Affairs Theses and Major Papers

As people move toward the coasts in growing numbers, the coastal zone is faced with ever increasing development pressures. The Town of Westerly, Rhode Island is experiencing many of the problems associated with these pressures. In order to expand a motel in the Misquamicut section of Westerly, the current owner of the property has proposed to extend city sewer lines to this area at his own cost. Afterward the line would be turned over to the town. While extension of sewer lines may relieve some local septic system failure problems, it could also spur more rapid and extensive growth. Over-development …
