On an annual basis, there should be enough water available to supply the spatial water demands, but the fluctuations throughout the year are equally important to secure the provision of water to consumers when it is needed. Storage is the key word to smoothen out the gaps between water availability and consumers demand. Besides the short term (overnight) storage in reservoirs to balance daily demand fluctuations, the longer term (weekly and longer) storage is provided by surface storage in reservoirs or by groundwater storage.
