3-Water divide- Water divide or Drainage Divide: The boundary between two adjacent drainage basins. Drainage divides are ridge crests (or less obvious locations where slope of the landscape changes direction). Runoff produced on one side of the ridge flows into stream ’A’ and runoff on the other side of the ridge flows into stream ’B’. Dendritic drainage pattern Dendritic drainage systems (from Greek δενδρίτης‚ dendrites‚ "of or pertaining to a tree") are the most common form of drainage system

“Acid Rain” Environmental science What is Acid Rain? Acid rain is a rain or any other form of precipitation like rain‚ fog‚ snow‚ or hail that contains harmful substances higher than normal amounts of such as nitrogen and sulfur oxides‚ that is unusually acidic‚ meaning that it possesses elevated levels of hydrogen ions (low pH). Acid rain is also called acid deposition because this term includes other forms of acidic precipitation such as snow. The acid deposition is occurs

Groundwater dams are structures that intercept or obstruct the natural flow of groundwater and provide storage for water underground. They have been used in several parts of the world‚ notably India‚ Africa and Brazil. Their use is in areas where flows of groundwater vary considerably during the course of the year‚ from very high flows following rain to negligible flows during the dry season. The basic principle of the groundwater dam is that instead of storing the water in surface reservoirs‚ water

Due to the recently recognized and rapidly increasing greenhouse effect‚ the process by which radiation from the planet’s atmosphere warms the surface‚ the overall temperature of the earth has risen‚ which affects every country differently. From melting ice sheets in Antarctica to vanishing reefs in oceans all over‚ global warming has affected nations worldwide‚ and Switzerland is included. Switzerland’s renowned glaciers and snowy mountains not only serve as natural water storage for Switzerland

and in developed countries is often used to supplement the mains supply. Rainwater harvesting systems are appealing as they are easy to understand‚ install and operate. They are effective in ’green droughts’ as water is captured from rainfall where runoff is insufficient to flow into dam storages. The quality of captured rainwater is usually sufficient for most household needs‚ reducing the need for detergents because rainwater is soft. Financial benefits to the users include that rain is ’renewable’
