Mathematical Model for Evaluating mass of Mangroves Forest along Coast Line of Karachi/Indus Delta

Abstract

Mangroves all over the world grow in tropical region, along tidal estuaries in salt marshes and muddy coast.In Pakistan, the mangrove forest spreads over the coastline of Sindh and Baluchistan. The area of mangroves has been estimated at about 250,000 ha, ranking the fifth largest mangrove area in the world. In this paper an effort has been made to develop a mathematical model, which can be appropriate to determine the mass of mangroves. To achieve this objective we require two parameters i.e. volume and density of the mangroves. In order to calculate the volume, the shape of the plant may be considered like mushroom. The leaves/branches scattered round the stem in the from of semi sphere and the exposed portion of stem in the from of cylinder
