Since the inception of the Institute, besides regular R and D work, the Institute has been carrying out studies referred to it by the various State and Central Government organisations on consultancy basis. Their number has been kept under a reasonable limit with a view to provide more weightage to research activities. Some research projects were sponsored and funded by Government organisations.

Under the sponsored studies normally the Institute takes up studies having research component which could lead to development of new methodology. Part of data for such studies are provided by the sponsoring agency and some data are generated by the Institute. Field test and laboratory analysis are also carried out by the Institute to determine various hydrological parameters.

With the experience gained in the past years and keeping in view the needs of developing expertise in emerging areas, it is preferred to take up sponsored studies in following areas :


Glaciers and snow studies


Integrated management of watersheds


Integrated hydrological studies of lakes


Development of indigenous hydrological instruments


Studies on groundwater contamination


Effect of climate changes on hydrological regime


Typical hydrological studies for problems of urban, arid and semi-arid, mountainous areas, command areas and deltas.


The Institute also takes up a limited number of consultancy works in the areas where the technology has been developed and tested by the Institute either under its applied studies or under sponsored studies. The Institute has developed expertise and capabilities in the following demand driven areas:


Groundwater modelling


Stream aquifer interaction


Reservoir operation


Sedimentation of reservoirs and lakes

The objective of this project was to identify the causes of waterlogging, and to design the subsurface drainage in the command area of IGNP main canal at RD 838. In this project, drainage coefficient has been determined through water balance, and field and intercepting drains have been designed.

Sabarmati System Studies
Integrated regulation of the Sabarmati system of reservoirs upto Ahmedabad city has been studied for various conservation purposes and for flood control. For each storage structure, optimum rule curves have been derived. A software and a flood control policy have been developed to assist the operation of gates for deciding  the safe release from the dam at any time. In addition a conceptual model has been calibrated for forecasting inflows at the dam site.

Glacier and Snow Studies
The objective of the project is to determine the of total melt water yield from the Dokriani glacier and its distribution with time. It involves collection of the meteorological and hydrological data near the snout of the glacier. The glacier was visited every year and data were collected on site. The data have been analysed to establish relationship between glacier melt runoff and meteorological parameters.

Integrated Hydrological Studies for Lake Nani
The objective of the project is to investigate water balance, sedimentation rates/pattern, hydrodynamics and pollution aspects of lake Nainital by using conventional and advanced techniques. The study of water balance, sedimentation rates pattern, hydrodynamics and pollution aspects of lake Naini were completed using conventional as well as advanced technique.

Integrated Management of Watersheds
The project aims to evolve appropriate model for integrated and sustainable development in the two small hilly watersheds located in Tehri-Garhwal District (U.P.), using an integrated approach of hydrologic instrumentation, field investigations and remote sensing and GIS. Digital Elevation Model (DEM) and drainage map for the two watersheds have been prepared. An automatic Weather Station has been installed for collecting data on half-hourly interval. The construction of channel and installation of a weir has been completed for measurement of runoff.

Development of Indigenous Hydrological Instruments
The objective of the project was to develop water level sensor, rainfall sensor, suspended sediment sensor to be used with an eight channel data logger. The complete set-up of datalogger alongwith sensors including Solar Power Panel were installed at Indo-German project site, Arki in Himachal Pradesh for the field testing.

Estimation of Irrigation Return Flow in Lokapavani Area in Krishnarajasagar Command
The main objectives of this R&D project under the collaboration with the State Government of Karnataka are the quantification of return flow vis-a-vis varying irrigation supplies and the development of methodologies for conducting similar studies in other command areas and setting up criteria for assessing the validity of the results beyond the specific studies sites.

Surface Water and Ground Water Interaction along river Ganga from Narora to Kanpur
The aim of the present study is to estimate the exchange of flow rate between river Ganga and the adjacent aquifer between Narora and Kanpur. The mathematical model for interaction of river and multiple aquifer system has been formulated. The expression for computing the river resistance parameter has been derived.
As per terms of reference, part of the data required for the study have been supplied by the sponsors. The remaining data pertaining to the study, were requested from the Ministry of Water Resources in December, 1998. As advised by Ministry of Water Resources the remaining classified data pertaining to river stage of Ganga in the study area are being collected from CWC, Lucknow.

Once the complete data are available, the developed model would be tested and study would be completed.

Temporal Distribution of Glacial melt runoff of Dokriani
The objective of this project is to determine the total melt water yield from the Dokriani glacier and its distribution with time. It involves collection of the meteorological and hydrological data near the snout of the glacier.The glacier was visited every year and data were collected on site for the four months melt season. A standard hydrometeorological observatory equipped with raingauges, evaporimeter, thermograph, hydrograph, anemometer, wind vane and sunshine recorder was set up at about 4000m altitude. For continuous monitoring of glacier melt runoff, an automatic water level recorder was installed near the snout at the glacier melt stream.  
Suspended sediment samples were also being collected at specified timings. In addition to the collection of meteorological and hydrological data, some experiments of snow and ice melt factors have been conducted on the glacier. Most of data have been analyzed and relationship between glacier melt runoff and meteorological parameters has been established. The final report of the project is under preparation.
