1. a) Roles of the riparian zone include filtering and buffering water through the various vegetation, acting as flood protection areas, trapping sediment and preventing erosion (though the roots of riparian plants) before they reach the water course, helping maintain local water table levels, shading by the riparian plants and keeping stream temperatures low during the summer for the fish, acting as a corridor for land mammals (e.g. bears, deer, squirrels), and overall maintaining biological…
Guard is urging mariners to use extreme caution while transiting the Merrimack River entrance due to significant shoaling inside of the north jetty.

Water quality of the Chippewa River vs. the Grand River Fresh water sources provide incredibly essential resources of biodiversity that aren’t found in abundance anywhere else. Surprisingly perhaps, new species are found with amazing regularity every year in fresh water sources. According to a study done on “Approximately 100 new species of freshwater fishes are described each year, compared with perhaps 2 new bird species” (Allan and Flecker 1993). Among the new species are species that are…

I must say you make some good points but I’m still unconvinced. Your opinion is very biased, you only look at the worst things about the reservoir and rarely address the pros the dam has provided. When you do you talk about them it is very briefly. There are many good things the dam has created. The reservoir created by the Glen Canyon Dam has provided many economic benefits. The reservoir currently has over 8,200 residents. In addition, about 4 million visiting tourists bring in $2.5 million…

The methods of construction, the tools, and the equipment used for the St. Francis dam were very common in this era. The actual construction at the dam site began in April 1924 and was led by superintendent Stanley Dunham. For the workers a large camp had been set up near the site for them to stay at. While at the camp Mulholland used his free time to look at the sites geological facts. The canyon contained a concrete batch plant and local aggregate was assimilated with 1.12 barrels of Portland…
Introduction Dams provide energy, water, and flood protection for communities, however as infrastructure ages the risk of dam failure increases (Bowels, 2007). The cost of large dam projects is increasing as climate change impacts the magnitude and duration of drought and storm events in California (Mann & Gleick, 2015). On February 7, 2017 Northern California Butte and Yuba County residents were forced to evacuate as the near failure of the Oroville Dam threatened downstream communities…
