Background

He has obtained B. Sc. and M. Sc Degrees from Technical University of İstanbul, Civil Engineering Faculty, Department of Reinforced Concrete in 1972. His further post-graduate studies were carried out at the University of London, Imperial College of Science and Technology. He was granted Diploma of Imperial College (DIC) in 1972, M. Sc. in Engineering Hydrology in 1973 and Ph. D. in stochastic hydrology in 1974. He worked in different countries such as England, Norway, Saudi Arabia and Turkey. He worked in different faculties such as the faculty of Earth Sciences, Hydrogeology Department; Faculty of Astronautics and Aeronautics, Meteorology Department. His main interests are hydrology, water resources, hydrogeology, hydrometeorology, hydraulics, science philosophy and history. He has published about 300 scientific papers in almost 50 different international top journals on various following topics:

  • Water Sciences
  • Hydrology
  • Hydraulic
  • Earth Sciences
  • Hydrogeology
  • Rock Mechanics
  • Engineering Geology
  • Atmospheric Sciences
  • New and Renewable Energy Sources
  • Hydrometeorology
  • Climatology
  • Modeling of Air Pollution
  • Mathematical Statistical
  • Stochastic processes
  • Chaotic behaviors
  • Fractal Geometry
  • Geostatistics
  • Kriging Methods
  • Fuzzy Logic
  • Genetic Algorithms
  • Artificial Neural Network

He has written many books in Turkish, one book in Arabic and English books are published in 1995 and 2008 by CRC Lewis Publishers with titles “Applied Hydrogeology for Scientists and Engineers” and "Wadi Hydrology", respectively; and another book in 2008 by Springer-Verlag with title "Solar Energy Fundamentals and Modelling Techniques (Atmosphere, Environment, Climate Change and Renewable Energy)". He has supervised many M. Sc. and Ph. D. degrees including about 10 international Ph. D. students from different disciplines and countries. He holds several national 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 2007. He is currently working at the Technical University of İstanbul, Civil Engineering Faculty. He is also the president of Turkish Water Foundation.
