Use of GIS in optimal spatial network of hydrological data in Betwa river catchment

The ultimate design for any kind of hydrological data network must evaluate all possible alternatives before rationalising the task of data collection at an optimal level. Wherever different kinds of data collection centres duplicate the measurement of same parameters in close proximity, efforts should be to integrate the entire process of data processing at one place. The extent to which the spatial aspect of data needs to be compromised is examined in this paper at sub-catchment/watershed level of Betwa river, one of the important southern tributaries of River Yamuna after Chambal. An integral design of various kinds of hydrological data has been attempted using spatial multi-criteria module within Geographic Information System (GIS) framework. Basic concept of geographical domain has been utilised to derive optimum network of hydrological data.
