| - | //GlacierData.txt// is a tab-separated file located in the [[start:hype_file_reference:info.txt&#model_options|modeldir]] folder. Sub-basins with glaciers are listed row-wise. The first row contains a column header with variable names. Variable names are not case-sensitive (max. 10 characters, no spaces). Columns with headings unknown to HYPE are skipped while reading the file, but must not longer than ten characters. Columns containing character strings, e.g. descriptive meta-data, must not exceed a length of 100 characters. The columns may be in any order. A value must exist for every column and row, i.e. empty cells are not allowed. This means that in the current form, zeros have to be filled in for all aquifer-related variables in sub-basin rows and vice-versa. | + | //GlacierData.txt// is a tab-separated file located in the [[start:hype_file_reference:info.txt&#model_options|modeldir]] folder.
