Hydrology is the science dealing with the earth's waters, their occurrence, circulation, and distribution, their chemical and physical properties, and their reaction with the environment. As such, hydrology is an indispensible requirement for planning in the field of water resources. Objectives for, spectrum of, and topics for education in hydrology as well as the present state and future trends of educational programs in this field are discussed. Included in detailed appendices are: (1) reference syllabi for hydrological topics; (2) syllabi for topics for advanced study in hydrology; (3) curricula and syllabi recommended for the education and training of professional personnel in operational hydrology, for complete undergraduate training in hydrology, for some Unesco sponsored post-graduate programs in hydrology, and for some undergraduate and graduate options in training for degrees in other fields than hydrology; and examples of short duration specialized programs and hydrology subjects included in programs for other degrees.
