Karim, I had read this several years ago and I encourage you to read it again with me.

Bear in mind this ADB effort is SUPPLEMENTAL to earlier and continuous UN efforts in cross-border hydrology. However this is ADB's point of view. ADB is a private concern (Bank) which has individual as well as national shareholders the last time I checked. Perhaps Yus is one of the shareholders. I know I am.

Here is the link. Join me while I review it again. There has been some minimal updating so perhaps there is new info that I was not privy to. I share with you that Norway and The Netherlands are also key partners of the UN in the assistance they render for hydrologic matters of developing nations.
