(b) Distant mixing zone:

In such a case, we approach

F₁(t)=(2π)^-1/2B σ_y^-1/2

F₂(Y,t)=exp[(-Y²/2σ_y²)]

F₃(Z,t)=e/H_h

being σ_y=(B²/16+2K_yt)^1/2. Here, we suppose that the plume was homogenized vertically when the water depth was H_h, that is the depth in the point where the thickness of the plume begins to occupy the whole layer of water. The program calculates considering the bottom of the sea like a flat surface. Then, H_h is the water depth at the location of the deepest outfall. If you want to consider a higher water thickness than outfall depth, you can draw a deeper outfall whose pollutant concentration is null. In asuch a case, the water depth is the depth of the deepest outfall. The calculation will not be affected by the null concentration of the deepest outfall.

(*)We have found, in our opinion, typographic errors in Orden del 13 de Julio de 1993 del Ministerio de Obras Públicas y Transportes del Reino de España, B.O.E. Martes 27 de Julio de 1993, página 22861 that we have corrected considering mathematical consistency. The software assumes the present corrections in the calculation.
