Detailed study of water cycle is the core of this course, with special attention for semi-arid region. Numerical equations, and statistical methods will be present  for the calculation of precipitation, surface-, near subsurface runoff,  and infiltration. Special attention will be given for hydrological data mining, validation of data, and monitoring program. Student will be able to analyze input/output  water sources  within a catchment area. Student will introduce also to different software.
