UM-1/2011 : NIH_Re SyP reservoir systems package (Version — 1)

Abstract

Because of the high time and space variability of rainfall and uncertain nature of monsoon in our country, storage reservoirs form one of the most important components of a water resources development project. The principal function of a reservoir is regulation of natural stream flow by storing surplus water in the rainy season and releasing the stored water in the dry season to supplement the natural river flow. Because of these reasons, more than 4000 major and medium dams have already been constructed all over the country to tap the available water resources so that the water can be utilized in accordance with the requirements of mankind.

Various kind of reservoir analyses are associated with reservoirs some of which include capacity computation, analysis of storage-yield relationship, reservoir routing, analyses of hydropower projects, operation of a multipurpose multi-reservoir system for conservation and flood control etc. Right from the inception of NIH, a number of software have been developed at NIH for these analyses. However, they were written in FORTRAN language which did not provide user-friendly environment to the field users. In view of this, a WINDOWS based package NIH ReSyP— Reservoir Systems Package has been developed. The interface has been developed in Visual BASIC platform and provides a user-friendly environment for carrying out various hydrological analyses related to reservoirs. The interface is capable of presenting the results in tabular as well as graphical form. Descriptive data forms have been prepared for easy preparation of data files. This User's manual provides detailed description of various data items for different analytical modules. Steps of analysis have been elaborated and important steps have been highlighted for compliance in each module. This is the first version (Version — I) of the software which contains ten analytical modules. It is planned to add more analyses modules (like reservoir sedimentation, spillway rating table etc.) in future to make it a comprehensive tool for all kinds of hydrological analysis for reservoir systems.
