into the following types which are riverine flooding, urban drainage, ground failures, fluctuating lake levels and coastal flooding and erosion. 2.6.1 Riverine Flooding When surface water runoff introduced into streams and rivers exceeds the capacity of the natural or constructed channels to accommodate the flow, water overflows the stream banks, spilling out into adjacent low lying areas. Riverine flooding occurs as a consequence. The dynamics of riverine flooding vary with terrain. In relatively
Physical changes in the hydrological cycle (driven by both climate change and human modification of the systems) in the case of reduced rainfall and/or increased evaporation would disconnect rivers from their floodplains and wetlands and slow water velocity in riverine systems, converting them into a chain of connected reservoirs or pools. These in turn impact the migratory patterns of fish species and composition of riparian habitat
Introduction On August 29th, 2005, Hurricane Katrina struck the Gulf Coast of the United States. The storm formed over the Bahamas as a tropical depression on August 23rd. The following day the tropical depression was named Katrina. On August 25th, Hurricane Katrina hits the Florida coast as a Category 1, with winds at 80 mph. The National Hurricane Center officially updates the track of Katrina from Florida to the Mississippi and Alabama coast. At this time, Governor Kathleen Babineaux Blanco declares

more desirable and losses in tourist satisfaction from increasingly recurrent coral bleaching events. Using economic representations of global tourism, recent studies have predicted that tourism preferences changing because of climate change could result in a significant loss of tourism revenues in the Maldives of over 30% by 2100. Present studies have shown coral bleaching events may limit tourism related to diving, fishing, and other interests connected to coral health. Climate change adaptation is
Egyptians, since (B.C. 1550) had known about toxic properties of substances of natural origin. Toxicology (Greek : Toxicon-poison, logos-study) is the study of toxins and their adverse effects on living organisms. The study of toxicology serves society in many ways to protect human and the environment from the deleterious effects of toxicants. It involves the study of internal and external exposures to
populations each year, means Inuit are forced into a difficult position. If they continue to hunt the caribou, populations will diminish; however, if the Inuit do not hunt them, they lose an essential part of their culture. This is where adaptive management becomes important for maintaining traditional sources of sustenance. A changing climate means the environment is less predictable and more extreme, making hunting using TEK almost impossible. It is this lack of access that leads to a loss in traditional
Nuclear power plants pose great risks to people’s health and the environment. Radiation leaks can cause DNA alterations to millions of people which may lead to cancer, different genetic mutations, and in worst case scenario, death. Nuclear waste disposal can cause great environmental problems and there is still no clear progress made regarding this matter. Until now, there are still no final depositories for thousand tons of nuclear wastes accumulated all over
