increment of human activity is one of the major causes of water scarcity. As world population keeps growing‚ the need of clean also increases simultaneously. This means an additional amount of water from various sources‚ such as river‚ dams‚ and reservoirs … will be rapidly exploited for both daily general use and foods/goods production. As a result‚ the environment absorbs more polluted water‚ causing disease and death. Furthermore‚ climate change is also a key factor causing the rareness of water

POSITIVE AND NEGATIVE IMPACTS OF DAMS ON THE ENVIRONMENT The human being has been struggling in order to shape the ecosphere in a man- ner he wants since the first day.

The most deep-seated environmental modification against the nature that had been realized in the history of the human being has started at this time. Even

The mechanism of heart contraction and relaxation (mechanical restitution) is the basic of cardiac functioning. This mechanical restitution is driven by calcium movement and concentrations. An increase in cystolic calcium concentration causes contraction in myocardium. Calcium from the extracellular fluid enters the cardiomyocyte through the L-type Ca2+ channels after being propagated by the cardiac action potential which depolarises the cell. This flood of calcium triggers more calcium release

There are lots of reservoirs in the upper course of the river‚ this is so that water can be provided to industrial cities to the east‚ for example Cow Green reservoir‚ which is actually located on the river Tees itself. The upper course of a river is a very good place for a reservoir as the valleys are narrow and steep sided they make excellent locations. Rainfall levels are high‚ evaporation rates are low and few people are affected by the building of the reservoir‚ this makes it the perfect

The flood storage reservoir upstream of the town can hold back floodwater’s‚ and so reduce the maximum flood flow through the town. A flood storage reservoir remains effective so long as it does not become full of water. Although‚ if a larger flood occurs‚ the reservoir fills up and the extra water will flow over the top. One other point is that this will be costly‚ but could save many businesses
