The purpose of this manual is to provide information on the programs that comprise the U.S. Fish and Wildlife Service’s Physical Habitat Simulation System (PHABSIM) – Version II. In Version I of PHABSIM there were essentially two steps. The first was to do hydraulic simulation and the second was to do habitat simulation. In Version II there are four steps. The first is to simulate water surface elevation, the second to simulate velocities, the third is to simulate the physical habitat versus streamflow relationship, and the fourth is to simulate the physical habitat when combinations of flows are involved. Also in Version II, programs with similar functions were combined. Major PHABSIM programs such as IFG4, WSP, and HABTAT still run the same, but may have enhancements. Other program functions may have been changed in Version II. Therefore, before running a program, review the program documentation, as the program may run differently then Version I…
