The WeSenseIt project developed the concept of a citizen-based water observatory, where citizens - such as volunteer flood wardens in the UK or civil protection volunteers in Italy - via mobiles and social media can be active in capturing, evaluating and communicating information on water levels, creating cost efficiencies and acting as early warning systems for over-stretched local authorities.

6. Notes also that, owing to the acceleration of glacial melting especially prevalent in the Himalayas and the Andes, mountainous regions are increasingly at threat from floods and avalanches; points out, however, that glacial melt is not the only factor affecting water flows in the Himalayas, but that timing and intensity of the monsoon, other rainfall and especially land use practices such as deforestation, overgrazing, agricultural systems and settlement patterns are determinant; in particular, stresses that deforestation frequently increases the rate and speed of the flow of water into major channels, while floods arising from ‘gla ...[+++]cier lake outburst floods’ (GLOFs) are often exacerbated by unsustainable land use practices;

17. Notes that there is no known method of reinforcing natural glacial lakes, but notes that the UNEP report on ‘High Mountains Glaciers and Climate Change’ (2010) mentions other methods to mitigate the effects of an outburst flood by using siphons and constructions of open channels and tunnels in order to lower the water level in the glacial lakes and by controlling the water flow into the local river system to use the water reservoir as a resource;
