One of the main objective of the Institute is to disseminate the knowledge of Hydrology for the benefit of both field engineers and academic organisations. Under the research programme, Institute has also taken up the work of software development.
Analysis of hydrological data as well as flood estimation form the basis of most of the hydrological studies. For a field engineer having limited knowledge of computer it becomes sometimes difficult to use the available methodology available in the form of computer programmes. Keeping in view this need, some interactive software packages have been developed by National Institute of Hydrology, for Unit Hydrograph derivation, flood estimation, reservoir and channel routing and reservoir operation.
These software are available along with a User's Manual covering various relevant details. Practicing Engineers and Scientists as well as R&D, Field and academic organisations will find these packages of immense use in the flood estimation for various hydraulic structures and similar other uses.

A reservoir is an important component of a water resources development project. Principal function of a reservoir is to regulate the natural streamflow thereby, changing the temporal and spatial availability of water for beneficial purposes such as municipal and industrial water supply, irrigation, hydropower generation, and navigation.
Reservoirs are commonly built in India for conservation and flood control purposes. Because of the high time and space variability of rainfall, reservoirs play very important role in the planning and management of water resources. More than 3000 major and medium dams have already been completed. Thus, a need was felt to develop a comprehensive software for Reservoir Analysis.
Capabilities
The software will be useful for various analyses related to design and management of reservoirs. It can be used for the following tasks:
- To compute reservoir capacity using Sequent Peak algorithm.
- To interpolate Elevation-Area-Capacity table for any elevation interval.
- To determine the firm power from a reservoir or to simulate the operation of a hydropower project.
- To simulate the operation of a multi-purpose multireservoir system for conservation purposes.
- To carry out flow routing through a reservoir using the hydrologic routing methods.
- To determine the reservoir operation policy using Stretched Thread method.
- To determine the rule curve levels using mass balance approach.
- To determine the required reservoir storage for a given yield or vice versa.
In addition to the analysis, the software includes graphical facilities also. After carrying out the analysis for a particular module, the software prompts whether a graphical display of the results is desired. Positive response produces on-screen graphs of the analysis.Please click here to download NIH_ReSyP Package
