Stimulus details: hydrological drought

impact chain for hydrological drought (click any node to view details):
Low river flows and water levels in lakes, rivers, reservoirs and aquifers are typical indicators for hydrological droughts, which are associated with periods of precipitation shortfalls on surface and subsurface water supply. Hydrological droughts occur when the amount of precipitation is insufficient to maintain the usually expected flows, levels or volumes in rivers, lakes and reservoirs. They are out of phase or lag the occurrence of meteorological droughts. Although it takes more time to show deficiencies in the components of the hydrologic system (soil moisture, stream flow, ground water, reservoir levels), these deficiencies of precipitation impact the hydrologic system dramatically. This deficit in groundwater storages in relation to normally expected storage levels affects utilisations that depend on theses water levels
