My research & development acti vity in t he field of environmental & nat ura l fluid m echanics ha5 b een started a fter one year 's working visit , proposed by Prof. Nguyen Van Dao, at the Laboratoire National d ' Hydraulique de France in C hatou , Fra nce ( 19791980) . Until now this activity is still a most important one. In the paper it is presented some selected scientific results in one of hydrodyn a mic problems for flood forecasting and flood control : developing of the lD hydraulic mod el, lD & quasi 2D model, ID hydraulic model for dam break flow , 2D hyd raul ic model, coupling of lD and 2D hydraulic models and some theirs applica tions for flood forecas ti ng and flood control in the Red River System. This paper is dedicated to the memory of Prof. Nguyen Va n Dao , wi t h whom 1 had a big chance to work and to collaborate during about 30 years, to whom I would like to express my heartfelt thanks. 1. PROF. NGUYEN VAN DAO AND MY RESEARCH AND DEVELOPMENT ACTIVITIES IN THE ENVIRONMENTAL AND NATURAL FLUID MECHANICS In 1977 year I have finished my thesis for obtaining the degree of Doctor of Science in the Moscow University and returned to Vietnam. At this time Prof. Nguyen Van Dao has been the General Secretary of the Vietnam Institute of Science. With his invitation and by his suggestion I have been appointed to a position of the Chief of Laboratory of Mechanics. During my long stay in Moscow University - a palace of fundamental sciences uot only in the former Soviet Union, but also in the vVorld, I tried to learn and to find out about perspective trends in modern development of mechanics as a branch of fund a mental sciences. In my understa ndings and conclusions , t he .
