The Maximum Drawdown, more commonly referred to as Max DD, is the worst (the maximum) peak to valley loss since the investment’s inception. [citation needed] In finance, the use of the maximum drawdown is an indicator of risk through the use of three performance measures: the Calmar ratio, the Sterling ratio and the Burke ratio.
In surface water hydrology and civil engineering, drawdown refers to the lowering of the surface elevation of a body of water, the water table, the piezometric surface, or the water surface of a well, as a result of the withdrawal of water. [1] In either case, drawdown is the change in hydraulic head or water level relative to the initial ...

Well testing differs from aquifer testing in that the behaviour of the well is primarily of concern in the former, while the characteristics of the aquifer (the geological formation or unit that supplies water to the well) are quantified in the latter. When water is pumped from a well the water level in the well falls. This fall is called ...
