Currently, there is a set up procedure to sort out the solid waste in the beach sand, by unit, amount and type of waste found with which it is determined the percentage of distribution of this throughout the sand as well as how hazardous it could be for visitors. Regarding the measurement of floating solid wastes, authors such as Botero INVEMAR, have stated methods that suggest the use of multifilament devices by moving on a boat at a constant speed along the coast line in a parallel way in order to catch the floating solid waste in seawater. According to the statement above, it was necessary to come up with a model which could be able to assess the efficiency of the method applied considering the sampling both in parallel and perpendicular to the coastline. Additionally, sample collection is proposed to be performed by a field auxiliary technician around the most crowded beach area and so the impact of a boat moving around may be diminished. The main objective of the developed model attempted to find the effective combination among all the given variables in order to come with an easy process to monitor parameters in a reliable way. Through this method, it is possible to get information with regards the type and percentages of floating solid waste at every beach in contrast with sanitary quality and the density of visitors in order to determine the nature of waste found in the seawater.

Periphytic algal community structure on Eleocharis acutangula Roxb. The aim of this study was to evaluate the influence of seasonal variation of environmental conditions on the structural attributes of the periphyton community on Eleocharis acutangula Roxb. The spring and summer were characterized by higher values of macrophyte cover, phytoplankton chlorophyll a , light, and phosphorus availability in the water. Periphyton biomass and algal density were negatively correlated with macrophyte cover and phytoplankton chlorophyll a.
