From: Alsaffar, Adnan To: 'Dr Christopher George IAHR' ; Subject: RE: Rivers-List: Fw: rivers-list: World Water Forum Date: dinsdag 23 november 1999 17:44 Greetings. there are two issues that may be considered this effort. The first deals with non point source pollution and the other is related to river bank erosion by boat traffic. Non- point adverse pollution is created by agricultural runoff including golf courses and residential area runoff contribute considerably to river water pollution. The continued use of fertilizers combined with waste water discharge from farms produces heavy loads of nutrient mostly phosphate and nitrates and others. These effluents cause deterioration to stream water quality, lakes eutrophication, and affects estuaries and bays as well. The other problem is caused by boat traffic in rivers and in particular leisure boating due to their high speed. Considerable areas of tidal wetlands and cliffs are lost annually by boating. There appear to be no regulation on boat speed size or restriction on boating areas exists. I am presenting these two issues for possible discussion in the Hague meeting. Thank you.
