Hydroperiod from Microtopography
This tool allows the computation of hydroperiod and water depth maps at a higher resolution from MIKE SHE and MIKE 21 model results. The model results used as input can be specified as:
The time period to process the model results can be customized to a shorter date period or to a Julian Day interval. The last option allows finding seasonal average magnitudes.
The user must select the desired options and enter the necessary grid files. They are the model result dfs2/dfs3 file and the higher-resolution topography file. After that, the user can specify the time period through which to process and compute the outputs. Please be aware that in dependence with the output resolution and the number of time steps to process, the tool could take up to several hours to complete the calculations.
This tool computes the water depth at the finer resolution for each time step by using a bilinear interpolation. The topography elevation could be in different units (i.e. feet instead of meters) and in a different geographical projection and grid rotation with respect to the model result files. A shorter processing period or a Julian Day interval could be specified. After processing all the time steps of interest, the tool can provide the following outputs:
It requires MIKE ZERO 2012, 2014, 2016, 2017 or 2019 to be installed, but the DHI license is not necessary.
Example of use
The screens shown below illustrate the processing of the file “Karup_Example_DemoMode1_3DSZflow.dfs3” by using the same resolution topography as in the file “Karup_Example_DemoMode1_PreProcessed.dfs2”, which are provided in the installation of the Toolbox.
The following screen compares the hydroperiod at the model resolution and at a higher resolution obtained from this tool. In the second case, the 10-times higher resolution topography was obtained simply from the preprocessed topography by using the bilinear interpolation method in the tool “resample dfs2 file”.
