I have a model which is set up to first iterate (using Feature Selection) through all points in a feature class using a unique value from field X (string). The model then takes this feature and runs it through the Get Field Value tool in order to identify the attribute for any given feature from field Y (string). This point is then fed into the Batch Watershed Delineation tool from the ArcHydro Toolset. Each of the input files for this tool are located in the same raster folder. Input files all begin with the same text. E.g. for Input Flow Direction Grid I have several files in my folder that start with "fdr" and end with the attributes gathered from the Get Field Value. I created a string variable which points to the folder containing the raster files. I named this variablerasterLocation. I have tried to reference each of the relevant input files in the Batch Watershed Delineation Tool, e.g. %rasterLocation%fdr%Y% However, I get the error message - "Input dataset does not exist or is not supported." ...

I am attempting to create watersheds on random points along a river network.These watersheds should capture every pre-existing water catchment which is upstream of that point. The Point Delineation Tool within the ArcHydro suite of tools is effective in generating watersheds encapsulating all of the area that drains to this point upstream. However, when I try to use my departments pre-existing water catchment dataset as the 'catchment' feature in the Point Delineation Tool I run into trouble as there are no GridIDs assigned to this dataset. I have tried to manually assign these values to the dataset but it is proving difficult to ensure that it all matches up with the other input datasets such as the Drainage Line dataset. I was wondering if anybody might be able to advise a workaround for this problem? ... View more
