Is the water in your local lake clean enough to swim in today? Currently, the only way to find out is for someone to take a water sample, bring it back to a lab, then report the analysis 24 to 48 hours later. Soon, however, water-sampling buoys anchored off of beaches could provide readings in real time.
Developed by scientists at Michigan State University and the US Geological Survey, each of the buoys contain sensors that continuously measure variables such as water temperature, clarity and bacterial content. Using an onboard cellular modem, they transmit that data to a shore-based server. Read more
As the climate warms up, more and more farmers in Switzerland need to irrigate their crops. This is problematic because many rivers carry less water. If the increase in water use is limited, agricultural production will not be significantly lowered. This conclusion was reached on the basis of models created in a project of the National Research Programme “Sustainable Water Management” (NRP 61).
Climate change will lead to regional water shortages. If the use of river water is not regulated, both water quality and biodiversity could be negatively affected. Overuse can be avoided by redirecting water from larger bodies of water via pipes and distribution networks. This comes at a considerable price and has an impact on the environment. Read more
Qiandao Lake, a man-made lake located in Chun’an County, Zhejiang, China, formed after the completion of the Xin’an River hydroelectric station in 1959. 1,078 large islands dot the lake and a few thousand smaller ones are scattered across it. The lake covers an area of 573 km² and has a storage capacity of 17.8 km³. The islands in the lake cover about 86 km² The first underwater exploration attempt of the drowned city was in 2001 when it was discovered there were 265 arches in the preserved ruins. Lion City is about the size of 62 football fields. Read more
This video was prepared by Toprak – Su – Enerji (Soil – Water – Energy) Study Group in Turkey. The video consists of sections of interviews with the local community and representatives during a journey to the Aral Sea Basin in May 2011. Existing situation of the water problem of the Aral Sea is described and key suggestions for the solution are given in the video.
As a result of the studies carried on for saving the Aral Sea, the North Aral Sea partially came back and water level reached to 42 meters. After the completion of the second phase of the project, water level will increase to the level of 46 meters. But, the Aral Sea will not reach to the level of 53 meters in 1960s. Solution for the South Aral Sea seems to be difficult. The South Aral Sea is almost completely dried up and and remaining water level is at 29 meters. Read more
