Effects Of Tide Gate Replacement On Water Temperature In A Freshwater Slough In The Columbia River Estuary, Sara Ennis
Effects Of Tide Gate Replacement On Water Temperature In A Freshwater Slough In The Columbia River Estuary, Sara Ennis
Environmental Science and Management Professional Master's Project Reports
Dramatic declines in salmon populations in the Pacific Northwest have brought new attention to the importance of estuarine rearing habitats. Levees and tide gates used to convert estuarine wetlands into farmland have reduced available habitat by more than half of historical levels. Recent efforts to restore estuarine habitats include tide gate replacement, though this method has been poorly studied. As a key indicator of salmon habitat suitability, temperature was used to evaluate the effects of tide gate replacement in a tidally influenced freshwater slough in the Lower Columbia River estuary. Three tide gates in the largest slough on Tenasillahe Island …

State Of The River Report For Toxics, Bradley Carter
Environmental Science and Management Professional Master's Project Reports
The United States Environmental Protection Agency (EPA) strives to prevent pollution, protect water quality and improve ecosystems in order to reduce risks to human health and the environment. As outlined in the Agency’s Strategic Plan, the Columbia River Basin was identified as a "National Priority" and designated as one of our nation’s seven "Large Aquatic Ecosystems". This designation grants legislative status equal to the Chesapeake Bay, Great Lakes, Gulf of Mexico, South Florida Ecosystem, Long Island Sound and Puget Sound. The Strategic Plan is the Agency’s road map of future work efforts, and targets specific goals that are expected to …
Downspout Disconnection Suitability And Incentives Analysis For The City Of Gresham, Oregon, Brian C. Fletcher
Downspout Disconnection Suitability And Incentives Analysis For The City Of Gresham, Oregon, Brian C. Fletcher
Environmental Science and Management Professional Master's Project Reports
The City of Gresham is developing a Downspout Disconnection Program, which encourages homeowners to disconnect their roof downspouts from the storm sewer system and divert the stormwater onto their lawn or rain garden. Downspout disconnection is being evaluated for its effectiveness to help the city meet stormwater discharge requirements in their NPDES-MS4 permit from Oregon DEQ. This study reviewed current Natural Resources Conservation Service (NRCS) soil data and developed a suitability map showing High, Medium and Low suitability zones for on-site stormwater management. To validate the map, 55 soil textural classes and 11 infiltration rates were determined at residences throughout …
