Abstract

Floods, a common, natural disaster, are the cause of major devastations in the physical, social and economic fronts besides loss of livestocks and human lives in many regions of the globe. Occurrence, intensity and areal extent of inundation are increasing rather rapidly since the past two to three decades. Regions known to be dry and parched and traditionally not vulnerable to floods are also experiencing unexpected and unusual floods. Now as floods and devastation continue to rise more and more flood plains would be affected and also degraded. For quite some time pressure on lands has also been rising in an unprecedented manner in different parts of the planet due to burgeoning population and for different developmental works. It is widely known that even control of floods also requires large areas of land for the construction of dams, reservoirs, conveyance channels, etc. We need today more and more lands. Cumulative effects of all these over the years have led to encroachment (eg. mostly uncontrolled and unplanned) on various lands namely, open spaces, forests, flood plains, crop fields, etc. These activities in reality have made absorption of flood water (ie, temporary holding, recharge of underground aquifers, unobstruded flow of run-off, etc.) more and more difficult and hence compounding the flood problems.

Abstract

Engineers in general are sectarian in their approach in confronting various issues and problems. Quite often they address and discuss them among themselves rather than with those concerned.

Abstract

Research, in general, implies man's attempts to understand Nature and to expand the frontier of knowledge and his applications of the knowledge thus gained for the welfare of the humanity of which he is a part. Research, however, has different shades of meaning to different people in India.

Abstract

Some problems of environmental pollution from smokes emitted from stacks and chimneys have been discussed here. The importance of similarity concept to investigate these exceedingly complex real life problems are also considered. In order to design an industrial chimney, according to the author, the "model-study" should be made obligatory by the provision of law to mitigate stack emitted pollution in the adjoining surroundings.

Abstract

BackgroundWater is highly mobile and variable in its distribution ; as a resource it is scarce and so it is costly-a fact seldom realised. As a resource we do not consider water in the same way the developed countries recognise it.

Abstract

The environment is contaminated more and more as a result of human activities and is being transformed into an unfavourable alteration for us. There is a need to educate the professional and the general public at large on the complexities of the pollution problem for the betterment of the society as a whole. A comprehensive training scheme has been drawn up to train experts and practicising scientists. Emphasis is also given on the other aspects of the professional activity.

Abstract

Lose of crop, property and life due to flood has turned almost into a regular feature in the eastern part of the country these days. Since the tragic flood of 1968 in the Teesta valley in North Bengal lots of debates were heard here and there including the parliament. Governmental activities were noticed. We have heard lots about flood control measures, flood warning system, flood control board, and what not. The hopes and assurances publicised through public presses and news bulletins proved to be castle in the air at the time of need, at the time of the problem.

Abstract

In almost all the branches of applied and development research, there are two main problems: the measurement or collection of data and the analysis and the meaningful interpretation of the data. There is one more difficulty-that is the delay in the analysis of the data. Not only it costs us money but it also poses to be major obstacle in the development and experimental research. We have a set of experimental data and we are concerned here to get the results at the earliest opportunity. And in most of the cases, we are not ready to appreciate or recognise the problems and difficulties involved with the analysing process. To make the analysis, the help of of research assistant is sought. The research assistant may be man or machine depending on the nature of the job. There are two aspects of data analysis. First one is the transformation or reduction of the data and second one is its interpretation. The job in the first case may be done either by a man or a machine while in the latter case it is clearly human activity.

Abstract

Very often one wonders why and how trenches are allowed to be cut on a newly constructed or a repaired road (sometimes even after one or two weeks). This is not all. Suppose, the gas-company people cut a trench first in some part of the road. Then the water-works men or electric-supply personnel or the Post and Telegraph men may come one after the other. As a result, the condition of the road is deteriorated, probably, more than what was before. The hardships and miseries of the public at large continue as before. Complaints never seemed to mend matters.

Abstract

This if a great privilege and also a pleasure to publish the Proceedings of the International Seminar on Terotcchnological Impact on Equipment Design, 19-20 Dec, 1988, organised by the Department of Mechanical Engineering, Jadavpur University, Calcutta.700032, India in a Special Issue of the Journal of the Association. In fact, this is the second time the Association are doing the job for same the Organiser for we have also published the 'Proceedings of the National Seminar on Tribology and Terotechnology' held on March 13 and 14, 1987 at the Department of Mechanical Engineering, Jadavpur University. We are glad that we have earned their confidence on us. We thank the Organiser for their appreciation of our work.
