(National Institute of Hydrology, 2010)Ecohydrology is a new emerging interdisciplinary science that deals with the interface between hydrology and ecology and seeks to focus on the role of ecological processes in modeling the hydrological processes and vice ...
-
(National Institute of Hydrology, 2010)During boreal summer, the troposphere over southern hemisphere is warming at a faster rate compared to that over northern hemisphere, and the intensity of the general atmospheric as well as the Asian-Indian monsoon circulation ...
-
(National Institute of Hydrology, 2010)Environmental flow refers to the water considered sufficient for protecting the structure and function of an ecosystem and its dependent species. This means enough water is left in our rivers, which is managed to ensure ...
-
(National Institute of Hydrology, 2010)Water quality in lakes is significantly affected by stormwater. After first rains, the lake water quality deteriorates due to washing up of municipal waste from the catchment area. In our country, the management of municipal ...

(National Institute of Hydrology, 2008)Drought is one of the most disastrous natural calamities that have affected human beings, agriculture and livestock throughout the history. Drought is characterized by deficit in water availability resulting either from ...
-
(National Institute of Hydrology, 2008)The drought-prone areas in India suffer from spatial and temporal variations in agricultural productivity. Traditional subsistence agriculture in vogue in these regions further enhances their vulnerability to drought. ...
-
(National Institute of Hydrology, 2008)Water is one of the most important natural resource for the existence and survival of any living being on the earth. It has been man's endeavor from time immemorial to utilize the available water resources. The surface and ...

(National Institute of Hydrology, 2008)Rainfed agriculture is important globally (80%)) with varying regional importance (95% in sub-saharan Africa and 60% of the farmed land in South Asia) and is also the hotspot of poverty, hunger, and water stress. Occurrence ...
-
(National Institute of Hydrology, 2008)In tropical monsoonal climate rainfall is subject to strong seasonality. Further, attributes of rainy season (starting date, ending date and duration) exhibit large spatial and temporal variations. Numerous notions of rainy ...
-
(National Institute of Hydrology, 2008)In a river basin with predominantly agricultural activity, management of limited water resources is very vital for sustainable development. Here drought research plays an important role in studying water deficits, so that ...
-
(National Institute of Hydrology, 2008)Droughts are due to acute water shortage and differ from natural hazard in many ways. Probability of its occurrence is high in arid zones. There are different approaches for drought management in crop production, the ...
-
(National Institute of Hydrology, 2008)Reservoirs are an important means for regulation of natural streamflows. Benefits from the structural facilities, such as dams, barrages. hydropower plants, etc.. largely depend on how well these are operated and managed. ...
-
(National Institute of Hydrology, 2008)Artificial recharge of aquifers is an important and necessary measure in combating water scarcity and mitigating drought. Artificial recharge aims replenishment of aquifers in order to obtain water at the time of need. ...
