This book covers the various aspects of the 3D cellular confinement systems (geocells) related to soft ground improvement. The improvement due to the provision of different geosynthetic reinforcements is quantified and compared in the book. In addition to the exhaustive and the up to date review of the literature, the book covers the simplified methodologies and 3D numerical modelling techniques for the design of the 3D cellular confinement systems. The important concepts are illustrated with the help of a case study highlighting the field application of the geocells. A new and innovative...

The study on negative externalities of the coastal ecosystem with categories of serious affected, medium affected and low affected fishermen and also positive externalities of coastal tourism was taken up in the cuddalore district of Tamil Nadu. The gross and net income was coincided with the pollution intensity and also the fish catch was varied with pollution intensity. The resource use efficiency of total production and Sardinella longiceps and Rastrelliger kanagurta species revealed the differential influence of fuel cost, numbers of fishermen and maintenance cost and depreciation cost of...

Sustainability evaluation of irrigated and rainfed agro ecological system study was taken up in the Namakkal district of Tamil Nadu. The net income was higher in sugarcane than the groundnut by 677.45 per cent. The seed, farmyard manure and human labour were significant in both the sugarcane and groundnut farms. Mean technical efficiency of both crops were almost similar. Farm size, Education, income, farmer's participation in village community meeting, frequency of participation in farmer fairs and extension visit had significant positive influence on green technology adoption....
