HEPEX is an international initiative bringing together hydrologists, meteorologists, researchers and endusers to develop advanced probabilistic hydrological forecast techniques for improved flood, drought and water management. HEPEX was launched in 2004 as an independent, cooperative international scientific activity.
The effects of climate change on the water cycle are profound and have been described as an intensification or a strengthening of the water cycle (also called hydrologic cycle). [2]: 1079 This effect has been observed since at least 1980. [2]: 1079 One example is when heavy rain events become even stronger.
As a drought persists, the conditions surrounding it gradually worsen and its impact on the local population gradually increases. Hydrological drought happens when water reserves available in sources such as aquifers, lakes and reservoirs fall below average or a locally significant threshold. Hydrological drought tends to present more slowly ...
Hydrological optimization applies mathematical optimization techniques (such as dynamic programming, linear programming, integer programming, or quadratic programming) to water-related problems. These problems may be for surface water , groundwater , or the combination.
Conceptual model describing the mechanisms of water flow attenuation within a beaver wetland with an unconfined floodplain. Ecohydrology (from Greek οἶκος, oikos, "house(hold)"; ὕδωρ, hydōr, "water"; and -λογία, -logia) is an interdisciplinary scientific field studying the interactions between water and ecological systems.
Rain falling over a drainage basin in Scotland.Understanding the cycling of water into, through, and out of catchments is a key element of hydrology. Hydrology (from Ancient Greek ὕδωρ (húdōr) ' water ' and -λογία () ' study of ') is the scientific study of the movement, distribution, and management of water on Earth and other planets, including the water cycle, water resources ...
As California grapples with worsening climate extremes, officials warn that recent storms don't add up to an end to the drought. With all this rain and snow, can California really still be in a ...
WaterGAP contributes to the Intersectoral Impact Model Intercomparison Project ISIMIP, [1] where consistent ensembles of model runs by a number of global hydrological models are generated to assess the impact of climate change and other anthropogenic stressors on freshwater resources world-wide.
