Difference in HEC-HMS & HEC-1
I am working on a project of recreating a hydrologic model of an area that was originally created in HEC-1. I have a print out of the input and output files but nothing electronic. So I retyped the HEC-1 input file and tried to run it in HEC-1. I am getting a "floating-point error, divide by zero" I have exhausted all my ideas of what is the problem with the file so I decided to try and model the system in HEC-HMS. I compiled the entire basin using the exact same inputs as the HEC-1 file showed and ran the model. When I compare the results from HEC-HMS and HEC-1, they are vastly different. Some sub-basins are 150% different in the peak flow values but others are only 5%. I can't seem to find where any of the inputs are different between the two files. Can anyone help me out and look at this or give me suggestions. Thanks in advance.
