Distributions of wave heights and periods are investigated against some theoretical distribution functions. The shallow water wave heights in general may be explained by Gluhovski distribution, which takes the form of Rayleigh for relative wave heights (H/d) equal to zero. For H/d approaching zero, which is observed in the case of postmonsoon swell dominated wave climate, wave height distribution follows Rayleigh. Rayleigh distribution for the square of the wave period fits the swell wave conditions than that of the sea. The present data do not conform to the joint distribution suggested by Gluhovski or Bretschneider as considerable correlation, with values of gamma (H, tau) ranging from 0.06 to 0.69, is observed between heights and periods. Some of these observations are found to be extendable also to other areas in the West Coast of India.

It is found that all the nuclides studied except super(131) I, attain steady state concentration more or less at the same time interval after continuous discharge, depending on the distance along the coast. Further, the confinement of radionuclides parallel to the coast is significant. Limiting discharge rates (LDR) for some typical radionuclides have been computed using a radiological model. The calculations show that the LDR values vary from 7 to 50,000 Ci.d/1, the lowest and highest being for super(239) Pu and super(134) Cs respectively.

TSM varies from 0.05 to 122 mg.l/1 in surface waters, and from 0.25 top 231 mg.l/1 in near bottom waters. TSM decreases away from the coast and from north to south. Higher concentrations of TSM generally occur off the river mouths and in the nearshore regions (is less than 30 m water depth). TSM is mainly composed of inert material in the nearshore region and off Godavari. Distribution pattern of TSM indicates that it closely follows the circulation pattern during the study period (August-September 1976). Combustible organic matter varies from 5 to 80U+0025 and these compositional differences in TSM are related to the biological productivity of these waters during the study period.

H sub(3) PO sub(2)/P super(0) and H sub(2) PO sub(2)/p super(0) are the strong reducing couples in acidic and basic solutions, respectively, in anoxic conditions. H sub(3) PO sub(4)/H sub(4) P sub(2) O sub(6) and H sub(3) PO sub(2)/P super(0) are the important reducing couples in seawater. HPO and H PO are the stable ones in oxic and anoxic seawaters, respectively. UO (HPO) are the most stable complexes in oxic seawater. Among the PO complexes CaPO is more stable.
