K.; Chalisgaonkar, Deepa 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. The present report has been prepared by Dr. M. K. Goel, Scientist "E2" and Smt. Deepa Chalisgaonkar, Sciemtist "E I" of the Water Resources Systems Division of this Institute. 2011-01-01T00:00:00Z http://117.252.14.250:8080/jspui/handle/123456789/554 Title: UM-1/2010 : Web based hydrology and water resources information system for India Authors: Chalisgaonkar, Deepa; Rathore, D. S.; Jain, S. K. Abstract: Water Resources management deals with technical, as well as socio-economic and ecological aspects and calls for an integrated approach and a comprehensive hydrological information system have become the key for efficient water management worldwide. The existing hydrological information systems in India lack reliability, accessibility and timeliness. The main causes are manual processing and wide gap between the tools available and employed, and involvement of many agencies, often lacking integration. Hydroinformatics is a new and rapidly developing field that integrates knowledge and understanding of water resources with the latest developments in information technology (IT) to improve decision-making in many critical applications. It encompasses methods for data capture, storage, processing, analysis and visualization, and the use of advanced modeling, simulation, optimization and knowledge-based tools and systems infrastructure. Considering the increasing popularity of IT in day-to-day functioning in all spheres of work, it can very effectively be utilized in the field of information dissemination. The report presents an easy to use and functional Web based Hydrology and Water Resources Information System for India developed at National Institute of Hydrology, Roorkee. The aim of this system is to distribute hydrology and water resources related information of India via the web. The information includes maps, diagrams and text describing the hydrology and water resources of India from national to river basin / sub-basin level in space and time. The system also covers important elements of hydrology including various terminologies and definitions. The idea behind the development of this system is to provide a low-barrier, cheap and flexible method of information dissemination worldwide on hydrology of India. 2010-01-01T00:00:00Z http://117.252.14.250:8080/jspui/handle/123456789/553 Title: UM-1/99-2000 : Learning package for hydrology Authors: Chalisgaonkar, Deepa Abstract: Computers have become an integral part of everyday life. In the new millennium everybody is should be computer literate as early as possible to keep pace with the developments taking place in the field of Information technology. Any country's social and economic wellbeing depends entirely on how well we educate people for a literacy intensive technological world. The computers have become a major tool for becoming competitive in the market. Considering the increasing popularity of the computers in day to day functioning in all kinds of work, there is a good reason to welcome their appearance in the teaching process. The report emphasises the necessity of Computer Aided Learning and presents a Learning Package on Hydrology covering various important elements of hydrology including various terminology and definitions used in the field of hydrology. 1999-01-01T00:00:00Z http://117.252.14.250:8080/jspui/handle/123456789/552 Title: UM-1/98-99 : Procedures for systematic processing of rainfall data Authors: Mehta, Rama D.; Chalisgaonkar, Deepa Abstract: Hydrometeorological analysis forms an important and integral part of hydrological research. One of the important parameters needed for this purpose is the rainfall which itself forms a part of the hydrological cycle. Rainfall data is collected by a number of organisations. It is a common experience that the rainfall data in its raw form contain many gaps and inconsistent values. As such preliminary processing of this data is essential before it is put to further use in analysis. Processing of the data has two major objectives. One is to evaluate the data for its accuracy and the other is to prepare the data in a most usable form to the users. In earlier times the processing was done manually. The need for use of faster methods of processing the data has been felt with the increase in the number of data records for processing and this led to the use of computers. The present report is an attempt to compile out the procedures for systematic processing of rainfall data. The concepts of rainfall data processing etc. have been discussed. It provides computer programs which are meant for processing and analysis of rainfall data collected from various sources. Different well documented computer programs, their description with input specifications and test input are given in Appendices. 1998-01-01T00:00:00Z
