Hi there, I am trying to make a flood plain for which I am using ESRI ARCGIS, HECGEORAS and HECRAS. I have been able to do all the hydraulic simulation HECRAS and the results from HECRAS has also been impoted into GIS using HECGEORAS. The problem I am facing after the import of the file is the raster image and the river geometric file doesnot overlay on each other though they have same projection (NAD_1983). Also when I try to make a inundation mapping with HECGEORAS, using the floodplain delineation using raster I get the following error.
error 010024
someone know what i am doing wrong?
