It ensures that the time between precipitation and the water getting to the sea is FAR greater, thus releasing valuable water to some regions during the dry season. In the Himalaya, Karakorum and Hindu Kush mountains, millions of people rely on the 90,000 glaciers as a water resource 9. The glaciers sit atop the Hindu Kush Himalaya mountain peaks where more than 240 million people live. Thus continuing this cycle again and again and again. Between 14-18% of the Himalayan glaciers is debris covered and they provide a significant amount of the total glacial melt water. Peak water is an important tipping point in glacierized catchment transiting from glaciers to no glaciers. Yet, their behaviour and response to climate change remains relatively unstudied. Case study: Glaciers and water resources in the Himalaya. Water is always cycling around, through and above the earth. If we consider annual runoff, we have an increase in annual runoff in the first place until the glaciers have shrunk so much that they cannot provide additional water. For example, the water you see in the rivers, lakes, and glaciers is available to us due to the water cycle. Of the many processes involved in the water cycle, the most important are evaporation, transpiration, condensation, precipitation, and runoff. It was always assumed debris covered glaciers melt less quick than debris-free glaciers at similar altitudes due to the insulating effect of debris thicker than a few centimetres. The developing countries in these … This is the continuous movement of water between the land, oceans and the atmosphere. Water flows through an ongoing cycle, called the natural water cycle. Groundwater may constitute anywhere from approximately 22 to 30% of fresh water, with ice (including ice caps, glaciers, permanent snow, ground ice, and permafrost) accounting for most of the remaining 78 to 70%. This process is very crucial in delivering the water from oceans to lands, and back again. As it flows through the cycle, water changes its state from liquid to steam (gas) or ice (solid) and back to (liquid) water. Water cycle, cycle that involves the continuous circulation of water in the Earth-atmosphere system. It comes after precipitation, as snow falls and lands on the glacier, this becomes compacted and hardens into ice under pressure from more snow above. ACT Water Cycle Diagram . Glaciers here are highly sensitive to climate change, and are rapidly shrinking 7,13. The communities around the mountain range get water directly from pools created by the massive ice hunks. A Multi-Phased Journey. Should global warming ever occur, the melting of glacial material would provide for a somewhat stable water level on Earth. What is Water Cycle? They also act as warehouses for the water supply. The water cycle is based upon precipitation falling, being used and/or absorbed by the Earth, precipitating back up through the soil and being evaporated. The total amount of water remains essentially constant. These glaciers form the headwaters of the Indus, Ganges and Brahmaputra rivers. Numerous rivers that provide water to billions of people throughout Asia, including the Ganges, Yangtze, Irrawaddy, and Mekong, all originate from the Himalayas. ACT Water Cycle. The water cycle is a continuous process that happens all the time around the earth. It can keep barren regions fertile.
