TS1 File Format

Introduction

This page contains information about the .ts1 file format used by TUFLOW for inputting boundary data. The Convert to TS1 can be used to convert a number of hydrologic model outputs to the .ts1 format. However, the format is relatively simple variant of a .csv file. It contains more information on the size and number of time-series and this makes it much faster to read into a TUFLOW model, particularly if there are a large number of input time-series. It could be readily scripted using a variety of tools such as Excel, Python or Matlab.

File Format

Line 1 !comment line
Line 2 <n time series>, <maximum number of output times>
Line 3 Start_Index , n time-series containing the start index of each output location (these are typically 1)
Line 4 End_Index , n time-series containing the end index of each output location (some time-seriesmay finish earlier and not contain the maximum number of output times)
Line 5 Time (min), n time-series x output label
Line 6 to end, data
Each data line is of the following format:
Time (in minutes). n time-series x data An example is below, it contains three time-series, with a maximum of 10 output times. The last time-series only contains five data points, all start at the first timestep, although this is not necessary.
Note: The time in the 1st column should be in minutes. Please check the _bc_tables_check.csv files to ensure that the file has been read in correctly.
In the example above the data has been written with a fixed column width for readability, however, this is not necessary in the .ts1 file.
