UM-36 : Processing and analysis of rainfall data

Abstract

Processing and analysis of rainfall data constitute an important component of hydrological analysis. Thee advent of computers, new techniques of hydrological analysis and special hydrological problems have placed new demands on hydrometeorological analysis.

Preliminary processing of rainfall data is essential before it is put to further use. The essential features of processing and analysis of rainfall data include storage of data on computer compatible devices, quality control, data conversion and further analysis.)

In this User's manual appropriate procedures for carrying out the various component processes oaf the system are described keeping in view the data collection and storage of rainfall data in India. Nine Computer programmes for handling the various jobs at processing and analysis of rainfall data are described together with the input and output specifications and sample input and output data.

These programmes are developed in FORTRAN-IV language and are implemented on the VAX-11/780 computer system available with the National Institute of Hydrology, Roorkee. All these programmes could be run on other computers including the microcomputers having the FORTRAN compiler after suitable modifications as per the software requirements of the system. These computer programmes are very useful to hydrometeologists and hydrologists involved in hydrological analysis and design.
