The primary purpose of the Global Flash Flood Guidance (GFFG) system is to provide real-time guidance products to forecasters worldwide. These products pertain to the threat of potential small-scale flash flooding over large regions with high resolution. The system provides the necessary products to support development of warnings for precipitation-induced flash floods. It uses real-time in situ and remotely-sensed data, numerical spatially distributed land-surface hydrological models and mesoscale numerical weather prediction models.

Hydrometeorological extremes account for more than 90% of all disasters caused by natural hazards recorded between 1994-2013. 2 Floods, storms, droughts and extreme temperatures alone affected more than 3 billion people, claimed about 600 000 lives and caused about US$ 2 trillion in direct economic damages during the same period. According to Global Facility for Disaster Reduction (GFDR) of the World Bank, economic assessment of meteorological and hydrological services indicates that as many as 23 000 lives could be saved and up to US$ 65 billion in economic benefits could be realized if...

WMO has continuously focused on promoting and facilitating the development of capabilities within National Hydrological Services in order to assist them in providing the best possible products and services for securing sound and sustainable water resources worldwide. This has been the Organization aim since it began working on issues in operational hydrology and water resources in 1961. Despite the numerous technological and computational advancements in hydrology, the focus has remained on the fundamental needs for robust water resources management and decision-making; that is, data and...

Bangladesh is located downstream of three large river basins: the Ganges, Brahmaputra and Meghna river basins. The total catchment area of these basins is 1.72 million km², with almost 93% of the catchment area situated outside the territories of Bangladesh – in Bhutan, China, India and Nepal. The topography, location and discharge from each of these three basins shape the annual hydrological cycle of the country.

On 20 June 2013, the community of High River in Alberta, Canada, found itself under water. With an intense and slow-moving storm stalled over the Rocky Mountains, torrential rain poured down on saturated ground for three days and hastened mountain snowpack melt, leading to rapid swelling of surrounding rivers and creeks. Highwood River, a Bow River tributary originating in the Rockies and cutting through the town of High River, expanded to 35 times its usual width and peaked in 8.5 hours at approximately 1 850 cubic metres per second (cms) of flood discharge. By the time the flood waters...

Modifications in water availability and quality over time and space – especially in the context of climate variation and change and growing water needs – call for adaptive management of water resources. The essential requirement for such an approach is detailed knowledge of the availability and usability of water resources in time and space. This implies knowledge of physical systems and their driving processes, and the availability of hydrological data in real time (precipitation, temperature, stream discharge and groundwater levels), together with data on water use and on environmental...

Water scarcity and droughts are not just matters of concern for water managers. They have direct impacts on the citizens and economic sectors that use and depend on water, such as agriculture, tourism, industry, energy and transport. Water scarcity and droughts also have broader impacts on natural resources at large such as through biodiversity, water quality, increased risks of forest fires and soil impoverishment. But how can such a complex natural phenomena be managed?
