The previously given order of principles already indicates a useful structure for the mathematical formulation. The storage volume poses the most essential dependency. In system hydrology, this type of dependency is known as a linear single stroage and can be thoroughly solved. Its principle is based on the assumption that the discharge is always proportional to the amount of water present in the storage (storage volume). The proportionality factor k is referred to as the storage constant. Taking into account the continuity equation and the storage constant gives the differential equation of the linear single storage. However, the storage equation is inapplicable to storage systems influenced by controls and operation rules. In this case, the discharges are not proportional to the storage volume, and therefore, an extension of the equation to any number of discharges is necessary.
