"Metropolitanisation has been observed by experts as one of the main characteristics of Indian urbanisation. Rural to urban migration has been a major player in urban growth of metropolitan cities, particularly Delhi. Not only Delhi but its hinterland [are] urbanising fast as compared to the hinterlands of other major cities of India. There are several processes of urbanization viz. historical, physical, demographic and economic. In this paper the role of demographic processes in urban expansion of Delhi [is examined]." 相似文献

This paper examines the interrelationships and interactions of the geomorphic features and the various hydrological parameters which control the development of water potential zones in the central Luni basin. Aerial photo-interpretation techniques were used to delineate the boundaries of geomorphological features, and facilitated the identification of twelve types of aquifers in eight geomorphological settings. The water potentials of these aquifers have been evaluated by taking into consideration nine important hydrological parameters which together govern water quality and yield. This investigation has revealed that the development of zones of ground-water potential is principally governed by the geomorphic characteristics of the terrain, which in turn is controlled by lithological variability, geological structure, drainage pattern, climatic characteristics, etc. The relevance of geomorphic characteristics has been evaluated by weight point analysis. Based on these findings, it is suggested that detailed studies of geomorphic features are of paramount significance for the rapid delineation of possible ground-water potential zones in arid and semi-arid regions. 相似文献

In this paper, vortex-induced vibrations of a cylinder are simulated by use of ANSYS CFX simulation code. The cylinder is treated as a rigid body and transverse displacements are obtained by use of a one degree of freedom spring damper system. 2-D as well as 3-D analysis is performed using air as the fluid. Reynolds number is varied from 40 to 16000 approx., covering the laminar and turbulent regimes of flow. The experimental results of (Khalak and Williamson, 1997) and other researchers are used for validation purposes. The results obtained are comparable. 相似文献

The evolutionary characteristics of a dust storm over Oman on 2 February 2008 were studied by analyzing the weather associated with it. The National Center for Environmental Prediction/National Centre for Atmospheric Research (NCEP/NCAR) reanalysis wind flow pattern at 1,000?hPa showed a clockwise and outward wind flow pattern over the study region, a manifestation of a high-pressure cold air mass. In addition, ground truth observations for surface temperature and surface winds showed cold northerly winds until the early morning of 2 February 2008. A strong wind shear resulted from differences in wind speed between warm air and trapped cold air. This vertical wind shear enhanced instability. Furthermore, the weakening of the inversion in the lower troposphere and the formation of a mixed layer due to transfer of horizontal momentum from upper air towards the surface led to strong surface winds. These strong winds lifted a large amount of dust particles off the ground, resulting in the dust event of 2 February 2008. 相似文献
