Based on survey data in the three different seasons (early season, wet season and dry season), this study showed seasonal variations of SPM concentration in the Cam - Nam Trieu estuary with river flow. SPM concentration was the highest in the dry season, with 62.95 mg/L, contrasting with river discharge.

The additive model simply adds absolute and unchanging seasonal variations to the trend figures where as the multiplicative model, by multiplying increasing or decreasing trend values by a constant seasonal variation factor, takes account of changing seasonal variations.. 10.8 TYPES OF FORECASTING AND FORECASTING METHODS.

Miron [Mir96, pp, 57–66] does not look at the frequency but at the amplitude of the seasonal variations. He argues that the seasonal variations observed in the economy are much stronger than the magnitude of the above external influences might justify.

The Poyang Lake wetlands change with seasonal variations in flood levels, and various types of habitats form during the process (Liu et al., 2011). These have developed a variety of wetland soils with abundant biodiversity (Liu et al., 2011. Wu et al., 2012. Zhang et al., 2012. Liang et al., 2015. Yang et al., 2015)..

In particular, the seasonal patterns, general periodic patterns with integer periods, can be constructed as sums of cycles. These fluctuations arise because of the regular changes in seasons or some other periodic events. The seasonal effects are regarded as corrections to the general trend of the series due to the seasonal variations, and these effects sum to zero when summed over the full season cycle. is always zero in the mean.

The environmental variables of the water column and Chl-a results are presented in Table 1 and these variables showed evident seasonal variations in the lagoon. The mean turbidity was observed between 3.51 and 12.91 ntu, the highest values were measured in December when the submerged macrophytes development was minimum in the lagoon. The mean total nitrogen (TN) was found between 0.92 and 4.67 mg L -1 with the highest values recorded in the summer months.
