2 Hydro-meteorological observations could be broadly defined as the scientific way for collection of flow data at a specific location along the river including selected meteorological parameters The reliability of the data is an important attribute for assessing the water resources in terms of quantity, quality and distribution in time and space.

3 Assessment of basin wise water availability and management Planning and design of water resources projects Study of climate change Flood forecast Flood mitigation Formulating National Water Policy

4 Reservoir inflow forecasting Water quality assessment Sediment assessment Morphological studies Assessment of navigational potential for inland waterways Resolving inter-state or international water disputes

5 Study of the effect of nature and human interference On surface water availability and its distribution Research purposes Estimation of periodical flow distribution during various seasons Other purpose

6 Water Level (Gauge) Discharge or Flow Water Quality Silt Selected Meteorological parameters including snow observations

7 Hydrological network optimization is a slow and evolutionary process, starting with a minimum number of stations, and increasing gradually (as necessary) until an optimum network is attained. An optimum network is achieved when the amount and quality of data collected and information processed is economically justifiable and it meets the users needs

8 Hydro-meteorological observation network in a basin depends on: Purpose or objective Terrain or Physiographic region in the basin

9 Minimum hydro-meteorological stations WMO Guidelines S N Physiographic Region Minimum density (area in km 2 per station) Precipitation Station Non recording Recording Evaporation Station Stream flow Station Sediment discharge and sedimentation Water Temperature (Water Quality Station) 1.

10 Primary stations Key gauging stations, Principal stations Maintained on long term basis to generate representative flow series Secondary stations Short duration stations Period enough to establish the flow characteristics of the river or stream. Special purpose stations Specific purpose stations or project stations or temporary stations Discontinued when the purpose is served. Fulfillment of legal agreement between co-basin states. The primary as well as the secondary stations also many a times serve as special purpose stations.
