Project FRIEND 

FRIEND (Flow Regimes from International Experimental and Network Data is an international collaborative study in regional hydrology. Its aim is to improve understanding of hydrological variability and similarity across time and space and thus develop hydrological science and practical flood design methods. It started in 1985 in Western Europe and now involves participants from over 90 countries around the world. Currently it is Project I.I. of UNESCO's fifth International Hydrological Programme. Project 5 "Catchment hydrological and biogeochemical processes in changing environment" is part of the Northern European FRIEND.

Except this group, there are

  • Alpine and Mediterranean Hydrology FRIEND
  • Southern Africa FRIEND
  • Nile FRIEND
  • Hindu Kush - Himalayan FRIEND
  • Western and Central Africa FRIEND
  • Asian Pacific FRIEND groups.
