Computer programming, and particularly problem-oriented languages, useful in solving water resources engineering problems are reviewed. The original HYDRO language started by G. Bugliarello and associates, was written in ALGOL. At present about 70 computation procedures are available, principally in hydrology, and hydraulic engineering. A FORTRAN adaptation of this language, called FORTRAN-HYDRO (FH), was developed. FH consists of a system of interlocking FORTRAN IV subroutines that may be strung or looped within a standard FORTRAN IV program. A library of 45 standard computation procedures in Hydrology and in Open Channel Hydraulics is available, and is expected to be extended. FH may be implemented on any computer having a FORTRAN compiler, and internal memory of at least 32K, and a fast access auxiliary memory. It has been found useful for teaching hydrology, hydraulics and water resources engineering. Some further work may make it of value to the practitioner as well. Methods of extending the library of subroutines as well as ways of contributing to it are suggested.
