A smoothed composite of the recessions of several observed hydrographs, drawn to represent the characteristic time graph of decreasing total runoff for a drainage area after passage of a peak flow. Curves of this type, designed to characterize the nature of a drainage area, may be constructed as a plot of flow (stage of discharge) versus time, or as a plot of flow versus flow at some fixed later interval; also, separate recession curves may be derived for surface runoff, groundwater runoff, and even for interflow.

A depiction of a three-dimensional object that results from stereoscopic viewing. A stereo image is obtained by simultaneously viewing a cloud, for example, from satellites at different locations from which the height of the cloud may be determined.

A function that has different constant values over adjacent subintervals; thus it has discontinuities at the ends of each interval. The distribution function of a discrete variate and a histogram have this shape.
Industry:Weather
The relationship for movement of fluids through permeable or porous media, such as soil, which states that at low Reynolds numbers the flow velocity ''V'' is proportional to hydraulic gradient ''dh''/''dl'', where the constant of proportionality ''K'' is the hydraulic conductivity:

Stacjonarne banku cirriform chmura oznaczenie górnej części systemu soczewkowe chmury w lee fala produkowane przez przepływ w górach sudeckich, w południowo-wschodniej części Niemiec; typu fenowego chmura. Moazagotl osiągnie maksymalny rozwój w chłodniejszych miesiącach, ale szczególnie jesienią. Zwykle występuje wtedy, gdy powietrze jest warunkowo niestabilny i prędkości wiatru przekraczać pewnych wartości krytycznych. Porównaj biskup fala, chinook łuku.

A graphic representation of the relationship of frequency to wavelength for wave motion.
The diagram is useful in determining the speed of wave motions and their dispersion characteristics. In ocean wave forecasting, it is a graph of the expression

In atmospheric electricity, a measure of the rate at which a given electrically charged object loses its charge to the surrounding air.
If the object bears a charge ''q'' at time ''t'', then according to a law established by Coulomb,
