The Impact Of Dams On Nitrogen Cycling In The Messalonskee Stream, Rebecca K. Forgrave
The Impact Of Dams On Nitrogen Cycling In The Messalonskee Stream, Rebecca K. Forgrave
Honors Theses
The Messalonskee Stream in central Maine has five hydroelectric dams on 16.6km. Each dam drastically changes the flow regime of the stream, dividing it into segments with different patterns of sediment settling and organic matter retention. I investigated how these disruptions impact nitrogen cycling, specifically nitrification rates above and below each dam. I expected higher nitrification rates above the dams, where levels of organic matter are higher, and lower rates below the dam where scouring removes organic matter and fine sediment from the streambed. I measured sediment nitrification rates with a nitrapyrin-inhibition assay and potential drivers of nitrification including sediment …
The Gilboa Dam And Its Possible Failure : What It Means For Nyc And Upstate New York, Kelly C. Owings
The Gilboa Dam And Its Possible Failure : What It Means For Nyc And Upstate New York, Kelly C. Owings
Honors Theses
The majority of the NYC water supply is provided by a system of dams and reservoirs that have been created in upstate New York. As the owner of this water supply system, NYC is responsible for managing each of the dams and reservoirs within the system. This responsibility includes upholding dam regulations in order to ensure the safety of the citizens of the surrounding area and to lesson any environmental impacts that may occur due to the water supply system. Of the 30 dams owned by NYC, however, 25 of them have been identified at a high-hazard level according the …
