HKH HYCOS Regional Training on Stream Gauging



The International Centre for Integrated Mountain Development (ICIMOD) in partnership with the World Meteorological Organization (WMO) and partner countries is implementing a regional project on ‘Establishment of a Regional Flood Information System (HKH-HYCOS)’.  The project is funded by the Ministry of Foreign Affairs, Government of Finland. The project has upgraded 38 hydro-meteorological stations in the four countries of Bangladesh, Bhutan, Nepal and Pakistan. After the upgrades, the real-time data from the hydro-meteorological stations will be used to improve national level flood forecasts to save lives and properties.  

Capacity building is central to the activities of HYCOS. During the 8th Regional Steering Committee meeting of HYCOS, the hydrological agencies expressed interest in stream gauging training. In response to this request the WMO in collaboration with the Department of Hydrology and Meteorology (DHM) of Nepal and ICIMOD is organising a training/workshop on stream gauging. 


The intended purpose is to train operational hydrologists/practitioners or trainers, including office and field staff, in stream gauging consistent with the Manual on Stream Gauging, Volume I - Fieldwork and Volume II - Computation of Discharge (WMO-No. 1044) []

Class Size and Duration

Restricted to 20 trainees per course, with training to cover six complete days. 

Field Session 

A field session will be conducted mid-way through the course on a stream or river that is typical (magnitude of flow, slope) to those monitored by participants. 

The Department of Hydrology and Meteorology of Nepal (DHM) will be engaged and will be providing equipment and local expertise to assist in describing the site, local equipment at the site, and how measurements are taken. Participants will use local equipment to take measurements. Operational Health and Safety procedures and practices of the National Hydrometeorological Services must be followed to ensure safe participation of practitioners when taking measurements. 

Material Requirements and Course Content 

WMO will make available hardcopies of the Manual to be provided to participants including a version on CD.   

One memory stick per participant, having a minimum memory of 16 gigabytes will be provided for their retention.  

All training materials will be made available electronically to trainees.  

Participants are asked to bring their own laptops as software will also be provided that will be loaded onto their systems to be used in some exercises.  

The broad content of the training is as follows:  

  • Selection of stream gauging sites 
  • Gauging station controls 
  • Measurement of stage 
  • Measurement of discharge by conventional methods 
  • Measurement of discharge by miscellaneous methods 
  • Indirect determination of peak discharge 
  • Uncertainty of discharge measurements
  • Discharge ratings by simple stage discharge relationships
  • Computations of discharge and databases   


WMO Secretariat has arranged provision and participation of two trainers from United States Geological Survey (USGS). The training will be provided in English language.
