(National Institute of Hydrology, 2016)In the recent few decades, importance of climate change has immensely increased due to global warming and its projected effects on hydrologic cycle. Rainfall pattern is extremely varied both spatially and temporally. ...
-
(National Institute of Hydrology, 2007)Kandi-belt is the steeply sloping submontane belt of the Himalayas fringing the Siwalik hills and extending discontinuously from Jammu and Kashmir to Assam. This dry-looking belt has undulating topography, steep and irregular ...
-
(National Institute of Hydrology, 2006)Sagar lake is situated in the middle of the Sagar city at an elevation of 517 meters above mean sea level in the Vindhyan terrain of Bundelkhand region. Lake surface area is 145 ha at full tank level. The maximum depth is ...
-
(National Institute of Hydrology, 2013)The soil erosion, movement and deposition are part of natural hydrological processes, but the rate of sedimentation is accelerated due to environmental degradation, lack of conservation measures, change in land use, ...
-
(National Institute of Hydrology, 2007)Glaciers lay across the Himalayan arc at varying climatic and hydrologic regimes and response of these glaciers to the climate change vary accordingly. Glacier size, aspect, elevation range and slope are the other major ...
-
(National Institute of Hydrology, 2006)Coastal tracts of Goa are rapidly being transformed into settlement areas. The poor water supply facilities have encouraged people to have their own source of water by digging or boring a well. During the last decade, there ...
-
(National Institute of Hydrology, 2005)The occurrence of drought leads to reduction in stream-flow, and consequent reduction in reservoir and tank levels and depletion of soil moisture and groundwater. There is a need to develop suitable criteria for planning ...
-
(National Institute of Hydrology, 2000)Soil erosion from a catchment is the result of complex processes, which is controlled by various climatic, topographic, geologic, geomorphic, and land use characteristics. Scientific planning for soil conservation ...
-
(National Institute of Hydrology, 1999)In this study, a model has been developed considering surface flow component and subsurface flow component along with the evapotranspiration from the crop as the sink term. The surface flow component is represented using ...
-
(National Institute of Hydrology, 1999)Reliable and accurate measurement of rainfall is an essential requirement in hydrological studies. For automated recording of rainfall data, tipping bucket rain gauges are generally used. It has been reported that the ...
-
(National Institute of Hydrology, 1999)Most of the current hydrologic, water management, and crop growth model require an accurate estimate of evapotranspiration (ET), for reliable applications. A large number of methods for calculation of ET from weather data ...
-
(National Institute of Hydrology, 1999)For planning and design of various types of water resources projects, estimation of flood magnitudes and their frequencies has been engaging attention of the engineers the world over since time immemorial. Whenever, rainfall ...
-
(National Institute of Hydrology, 1999)Uncertainty analysis outlines the inability to exactly model a real world hydrologic situation even if the best possible estimates of the input parameters of the model are utilized. An added complication with most of the ...
-
(National Institute of Hydrology, 1999)The linearity principle of unit hydrograph theory has been widely applied for the simulation of rainfall-runoff process, particularly for small and medium sized catchments. Derivation of unit hydrograph has been extensively ...
-
(National Institute of Hydrology, 1999)Coastal aquifers that are in hydraulic continuity with the sea are vulnerable to seawater intrusion. Besides the lateral intrusion of seawater, the coastal aquifer may also be subject to a vertical recharge of saline water ...
-
(National Institute of Hydrology, 1999)Success of an irrigation system depends on efficient water management. Irrigation scheduling, which anticipates the temporal water need of crops, i.e., when to irrigate and how much water to apply, is an important management ...
-
(National Institute of Hydrology, 1999)Estimation of sediment load from the glacierized basins is very important for planning, designing, installation and operation of hydro-power projects including management of reservoirs. In the present study, assessment of ...
-
(National Institute of Hydrology, 1999)Wetlands in India have assumed a considerable significance in recent years because of their ecological significance in terms of flood control, water purification, aquatic productivity and microclimatic regulation, and as ...
-
(National Institute of Hydrology, 1999)Lakes play an important role in shaping the hydrological, ecological and environmental balance of the region by developing flora, fauna and habitation of aquatic biota. Like other lakes of the world, Sagar lake is also ...
-
(National Institute of Hydrology, 1999)The Dal-Nagin lake is a Himalayan lake which is located in the heart of Srinagar at an average altitude of 1583m. The lake comprises of four major sub-basins, Hazratbal, Bod Dal, Gagribal & Nagin. In spite of various ...
