Abstract:
For optimum planning of the utilisation of the water resources of Gujarat State, the urgent need of correct assessment of the availability of water resources on the basis of an efficient hydrological network has been greatly felt in the recent times. Such efficient network comprises the instrumentation for accurate observations of various hydrological parameters, viz. precipitation, evapotranspiration, runoff, silt, daily maximum and minimum temperatures, direction of wind and wind velocity etc. This paper describes the progressive development of the present modernised hydrological network established in Gujarat State. The existing established network has been found well satisfactory compared to the World Meteorological Organisation's ( W.M.0.) criteria in respect of raingauge and river gauging. The present set-up of weather stations, when duly stepped up as per the programme, will strengthen it to achieve the desired standard.
