Watershed

Rainforest is a temperate rainforest of 6.4 million hectares, home to many rare and endangered species, as well as watersheds that provide the best salmon runs left in Canada. Unfortunately, the Great Bear Rainforest is under threat due to clearcutting and its effects on the environment. According to the David Suzuki Foundation, “30% of logging in the Great Bear Rainforest has been in watersheds since 2001”, meaning the water quality of that area has been affected. As for wildlife, deforestation…

riparian areas control most of the run-off, and there are several ponds located on the near the perimeter of the coast. There are four major watersheds on McNabs Island. Since most of the drumlins are oriented from northwest to southeast it seems apparent that most of the drainage channels would run between the depressions. An example of this would be the watershed that leads into Ives Cove. It passes underneath a trail, through a wetland area, and into a pond near the coast. The drainage…

rising sea levels are expected to create disproportionate flooding in coastal areas. As a resident of State College, Pennsylvania, my local watershed, Bald Eagle Watershed, lies within Region 3 and will likely incur similar impacts as other inland areas of the Mid-Atlantic…

3. Transport pathways in different environmental media Generally, Phosphorus enters the environment through three basic pathways; Air, Water, and Soil. Specifically in the Watershed Nature Centre, Phosphorus is observed to be leached through the soil and resident in the water sediment with periodical release into the water body. a. Air In general, phosphorus is not likely to spread, because it reacts with oxygen fairly quickly. When phosphorus ends up in air through exhausts it will usually…

Chronic Obstructive Pulmonary Disease (COPD) is a major originate of chronic morbidity and mortality. The term COPD does not refer to a single disease but is an umbrella term for chronic lung diseases that irreversibly limits the flow of air in the lungs. CT imaging is able to perform in visualizing the effects of COPD. An advantage of CT over Lung Function Test (LFT) is that CT can differentiate between the different types of COPD, making it possible to classify the different subgroups of…

Geologically, Greensboro is situated at the headwaters of the Cape Fear River Basin, the biggest of the 17 noteworthy waterway bowls in North Carolina. The Reedy Fork Creek and Buffalo Creek bowl (Figure 1) in Greensboro are framed from precipitation that keeps running off impenetrable and pervious surfaces, and from water that leaks up from neighborhood springs and in the long run winds up in the Ocean, only south of Wilmington, NC. The bowl is situated in a move zone between warm-mild and…

I found out that a watershed is an area that drains water into a river or a lake, and is composed of uplands and wetlands. Uplands are on higher ground, and wetlands are on lower ground. Watersheds are important because they collect rainwater so that it can be purified and drain into aquifers which are used as a water source by humans. The watershed here is 60,000 acres large. If the watershed did not exist, water would become polluted by the land we live…

False Brome Invasive Activity in Oak Creek Watershed Introduction The intent of this document is to observe and characterize the activity of Brachypodium Sylvaticum (False Brome) as a noxious weed at Oak Creek watershed near Corvallis, Oregon. False Brome is a slender, drooping bladed, perennial bunch grass that is native to Europe and North Africa. It was first introduced to Oregon in the 1930’s and by some estimates, it has spread over 10,000 acres in Oregon—specifically in Western Oregon:…

The Meramec River is located in the upper Ozark Highlands in central-eastern Missouri and spans 218 linear miles before discharging into the Mississippi River in St. Louis (Blanc 1999, Thom et al, Figure 1). This watershed is dominated by Oak-Hickory forests and karst topography; and the Meramec River follows a riffle-run pattern of stream flow (Blanc 1999, Thom et al). Before people dominated the landscape, the driving forces of nature shaped the topography and the subsequent ecosystems that…

events. (60 points) Consider the case that due to climate changes, the existing design of the reservoir and the pipe system in an urban and residential area within a watershed (see Figure 1 below) can no longer handle the floods or sustain the droughts. Impacts of the climate changes on the watershed in this case…
