THEMATIC REPRESENTATION OF SEDIMENTS DISTRIBUTION IN PICHAVARAM MANGROVE FOREST

The purpose of this study was to present the substance classification of heavy metals of River sediments at Pichavaram Mangrove Forest Lake in the Chidambaram, Tamilnadu, India. The quality of water commonly reflects the force of seawater and the uppanru estuary encroached by evaporation and in situ energy content which is accumulated during a given period of time. The biological process controlling the exhaustion and oscillation of dissolved silica. Nitrate and phosphate are derived from fertilizer input which is being used in nearby agriculture fields. Deforestation and re deferment processes causes the unreliable range of Total Suspended matter (TSM). Sand and silt occupies 80-93% of the total sediments. The fluctuations of chemical concentrations were identified in the water and the sediments combination. Unique chemical behaviour of sediments can be seen from heavy metals enrichment of the samples. To show the distribution of heavy metals in the area, thematic process was carried out by using ARC GIS 9.1 software.
