He has written many books in Turkish, one book in Arabic and several in English. He supervised many national and international students for M. Sc. and Ph. D. degrees. He holds several national (Encouragement Science Price for Young Scientist in 1978, Science Price in 1993 both from the Scientific and Technological Research Council of Turkey, etc.) and international scientific prizes and the most recent one is given as a team work due to his contribution to "Nobel Peace Prize" through his works in IPCC form 2002-2007 concerning Climate Change. He also holds Science Encouragement Prize (1978) and Science Prize (1993) from Science and Technology Center of Turkey in addition to administration and Science Prize from the King Abdulaziz University, Jeddah, Kingdom of Saudi Arabia. He also has a chair at Prince Sultan Research Center, King Saud University, Riyadh. He worked with the Saudi Geological Survey for three years as a full time consultant on various water, climate change and groundwater issues in the Kingdom of Saudi Arabia. He worked also with the ARAMCO as a consultant for hydrogeology and groundwater training program development. He made numerous other national and international consulting works on water resources, climate change, renewable energy alternatives, earthquake engineering, earth sciences and similar projects. He is currently working at the Technical University of Istanbul, Civil Engineering Faculty. He is also the president of Turkish Water Foundation. He holds several national and international scientific prizes and the most recent one is the "Nobel Peace Prize", which is given as a result of team work during his actual contributions in IPCC form 2002-2007 concerning Climate Change Impact on Fresh Water Resources.
