HSPEXP interactively allows the user to edit the input User Control Input (UCI) file for the Hydrologic Simulation Program--Fortran (HSPF), run HSPF simulations, produce plots of HSPF hydrology outputs compared to observed values, compute error statistics for a simulation, and provide the user with expert advice on which parameters should be changed to improve the calibration. In general, use of HSPEXP is an interactive process that requires repeating the cycle of simulation, computing statistics, reviewing plots, getting advice, and modifying parameters.";
