In geometry, the sagitta (sometimes abbreviated as sag [1]) of a circular arc is the distance from the midpoint of the arc to the midpoint of its chord. [2] It is used extensively in architecture when calculating the arc necessary to span a certain height and distance and also in optics where it is used to find the depth of a spherical mirror ...
the permissible long term average depth of the water table (Dw) on the basis of agricultural drainage criteria; the soil's hydraulic conductivity (Ka and Kb) by measurements; the depth of the bottom of the aquifer (Di) the design drain spacing (L) can be found from the equation in dependence of the drain depth (Dd) and drain radius (r ...
During uniform flow, the flow depth is known as normal depth (yn). This depth is analogous to the terminal velocity of an object in free fall, where gravity and frictional forces are in balance (Moglen, 2013). [3] Typically, this depth is calculated using the Manning formula. Gradually varied flow occurs when the change in flow depth per change ...
One extends from the western coast (near Tasaral Island) to Cape Korzhyntubek, while the second lies south from the Gulf Bertys, which is the deepest part of the "half". The average depth of the eastern basin is 16 m and the maximum depth is 26 m. [14] The average depth of the lake is 5.8 metres, and the total volume of water is about 112 km 3 ...
Bathymetric charts showcase depth using a series of lines and points at equal intervals, called depth contours or isobaths (a type of contour line). A closed shape with increasingly smaller shapes inside of it can indicate an ocean trench or a seamount, or underwater mountain, depending on whether the depths increase or decrease going inward. [27]
To get an IDF curves from a probability distribution, it is necessary to mathematically isolate the total amount or depth of the event , which is directly related to the average intensity and the duration , by the equation =, and since the return period is defined as the inverse of (), the function is found as the inverse of (), according to:

There are many programs and algorithms used to plot the Mandelbrot set and other fractals, some of which are described in fractal-generating software.
where H b is the wave height at the breaker line and γ is the breaker index (wave height/water depth ratio at breaking for individual waves, usually γ = 0.7 - 0.8). Incidentally, due to this phenomenon, a small reduction in water level occurs just seaward of the breaker line, in the order of 20% of the wave set-up.
