HEC-2, Water Surface Profiles
The HEC-2 program computes water surface profiles for one-dimensional steady, gradually varied flow in rivers of any cross section. Flow may be subcritical or supercritical. Various routines are available for modifying input cross-section data; for example, for locating encroachments or inserting a trapezoidal excavation on cross sections. The water surface profile through structures such as bridges, culverts and weirs can be computed. Variable channels roughness and variable reach length between adjacent cross sections can be accommodated. Printer plots can be made of the river cross sections can be accommodated. Printer plots can be made of the river cross sections and computed profiles. Input may be in either English or metric units. See separate program description for the HEC-RAS system of software.
