The top layer of accumulated sand washed down by floods over millions of years, makes river floodplains into giant aquifers. We propose a scheme for the natural storage of excess monsoon river-water discharge in the extensive and deep sand top layer of the floodplain of the river. The excess monsoon …
The Himalayas has one of the largest concentrations of glaciers and permanent snowfields outside the polar region. Snow and glacier melt forms an important source for many rivers originating in the Himalayas. Numerous studies suggest that global warming has started affecting snow melt and stream run-off in the Himalayan region. …
Southwest monsoon (SWM) controls the majority of the agricultural activities in Tamil Nadu (TN), though the amount of rainfall received due to this is relatively less. The nature and behaviour of water vapour over TN reveal the other dynamic processes that are in operation during this period of the year.
Kodaikanal Lake which forms the heart of the resort is a star shaped lake, covering an area of about 24 hectares. Kodaikanal Lake was created in 1863 by Sir Hendry Levinge. The objectives of this study is to assess the physico-chemical and biological quality of the Kodaikanal lake and to …

Fundamental to the onset of the Indian Summer Monsoon is the land-sea thermal gradient from the Indian Ocean to the Himalayas-Tibetan Plateau (HTP). The timing of the onset is strongly controlled by the meridional tropospheric temperature gradient due to the rapid pre-monsoon heating of the HTP compared to the relatively …
In the coastal community of Chabihau, Yucatan, Mexico, hurricanes Gilbert (1988) and Isidore (2002) opened breaches in the coastal dune. The government modified these breaches with a floodgate, channels, and bridges, allowing tidal influx that has transformed the swamp ecosystem into a coastal lagoon. Our long-term research (1990-2006) has been …
Total atmospheric moisture content present in the atmosphere is less than 1% of total atmospheric composition. The atmospheric moisture variability accounts for nearly 10% variation in global hydrological cycle. The atmospheric moisture variability occurs in the form of cloud cover and hence in to the precipitation. A prior knowledge of …
