2. Stratified model
This model is official in Spain and it follows 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, I. Disposiciones generales. Proyecto de conducciones de vertidos desde tierra al mar.
The stratification phenomena is the existence of two homogeneous water layers and separated by a thin thermocline layer. In such a case, we can say that the water is stratified. There is no exchange of pollutants through this picnocline layer. In case we suppose that a picnocline layer exists, we will be able to check the stability by means of the application of the following equation:
[u02 B+ Ua2 H]/[(u0 B g’)2/3 H] <0.54
Typical values (pollutants): Organic matter as DBO5 - 350g/m3 Suspended matter - 600g/m3 E. Coli - 1012 /m3 N2 (total) - 30 gN/m3 Effluent velocity - entre 0.6 y 0.8 m/s Port diameter - 6cm
Dispersion coefficients: Horizontal dispersion: Ky(m2/s)=3x10-5 B4/3. B=initial plume width(m)
Vertical dispersion: Kz(m2/s)=4x10-3 Ua e e= thickness of the mixing layer Ua=horizontal ambient velocity (m/s)
