TN-100 : Hydrological data processing

Abstract

In December 1985 the governments of The Netherlands and India agreed on an Indo-Dutch Training Programme on Water Management ( WAMATRA ). Phase I was concluded in 1986-87. Phase II of WAMATRA started in August 1990. National Institute of Hydrology was associated along with other institutions in this project in a few areas. One of the items was "Data Storage and Retrieval System". The Delft Hydraulics from the The Netherlands side was to organize courses, training and workshop under this item.

In April/May 1991 a one week course was organized by Prof. H J M Ogink and Mr_ Johan Crebas of Delft Hydraulics. A software package on Storage, Processing and Retrieval of Hydro-meteorological Data called HYMOS was introduced to the participants. After this introductory course Shri Hemant Chowdhary recieved an in-depth training on the software at Delft Hydraulics, De Voorst for two months during Oct./Dec. 1991.

This technical report on his training on HYMOS covers general principals of database management system in its Part I and a detailed information of the capabilities and procedures of HYMOS in Part II. An idea has been given, in Part I, about the necessary features of a good database management system. While in Part II various capabilities of storage, processing and retrieval of hydro-meteorological data have been elaborated. An attempt has been made to discuss every option of software in Part II so as to give a complete understanding of the package. The main components of the package are entry and editing (storage of data), validation, completion, transformation, statistical analysis time series analysis (processing of hydrological data) and reporting, retreival and transfer of data (retreival of data).
