Climate is a major driver of forest species distributions and the growth rate and structure of forests. Thus, climate change can potentially have significant effects on mountain forest hydrology, particularly the amount of water available downstream. However, many other factors influence forest biomass and mountain hydrology, and climate change effects cannot be viewed in isolation from previous land use histories (i.e. forest legacies), altered disturbance regimes (e.g. fire frequency, insect outbreaks, floods) and invasive species.

In the middle and greater Himalaya, natural springs are the main source of domestic water consumption, but their discharge does not remain constant with time. Erratic rainfall directly affects the recharging of the spring catchment. In this communication, the behaviour of a perennial spring with rainfall variation is analysed from eight years

A study has been conducted at the Naokari limestone mine located at Chandrapur district of Maharashtra state, to investigate the hydro geological condition between the mines and the surrounding areas. Water resources accounting by the demarcating different watersheds and quality of water has also been carried out to analyse major cause of ground water scarcity in the area during dry season.

The two most important hydrological extremes are floods and droughts. These events pose serious hazards to human populations in many parts of the world. These water related disasters are caused because of large diversity in climate and topography of the country. Climate change in future is expected to have severe implications on river flows in South Asia including India. Global climate change is likely to result in severe droughts and floods in India, with major impacts on human health and food supplies.

Lake Oussudu, which is the largest wetland in the Union Territory of Pondicherry, is one of the most important bird sanctuaries in India. Apart from being an important water resource and a heritage site, Oussudu watershed also caters to the other needs of the people living around the lake; notably fishing, grazing of the domestic livestock and harvesting of reeds.

A lot of wash load comes to the streams during the rainy season due to the erosion of soil from the catchment and known to flow practically without settling on the streambed. The presence of wash load is known to affect the resistance to the flow. The effect of its presence on transport of bed material load is not well known. The present paper is devoted to a review of the studies regarding concept of wash load, changes in resistance to flow due to the presence of wash load, the effect of presence of fines in suspension on the transport of bed-material.

Climate models and satellite observations both indicate that the total amount of water in the atmosphere will increase at a rate of 7% per kelvin of surface warming. However, the climate models predict that global precipitation will increase at a much slower rate of 1 to 3% per kelvin. A recent analysis of satellite observations does not support this prediction of a muted response of precipitation to global warming. Rather, the observations suggest that precipitation and total atmospheric water have increased at about the same rate over the past two decades.
