DHI Tools

Fork of Rob Wall's dhitools Package: https://github.com/robjameswall/dhitools

Key changes:

• Support for quadrilateral meshes
• Support for 3D dfsu filetypes (sigma only are fully integrated, sigma/z-layer are semi-integrated.)
• Separated out plotting routines into a new module for more flexibility

To do:

• Add notebook examples of 3D and quad working
• Check functionality with sigma/z-layer meshtypes
• Implement direct item plotting from 3D dfsu files (without first converting to 2D)

DHI Tools

Python tools for working with DHI MIKE21.

Features:

• Interpolate multiple raster DEMs directly to .mesh file
• Read and analyse .dfsu files
• Create .dfsu roughness map (or any other map) directly from .shp and .mesh
• Read and analyse .dfs0, .dfs1, .dfs2 files

Due to depending on the MIKE SDK DLL libraries only Windows is supported.

Install

Requirements

• MIKE SDK 2019
• GDAL/OGR
• Geopandas
• Pythonnet

Install

Recommended that Anaconda is used to install GDAL and geopandas. Alternatively, see here and here for installation instructions of these packages.

First, install MIKE software development kit:

Download installer from here

After installing the MIKE SDK:

conda install gdal
conda install geopandas
pip install pythonnet
pip install dhitools

Examples

See the following Jupyter notebooks for examples:

• Interpolate mesh
• Create roughness map
• Dfsu analysis - reading items, calculating statistics, plotting, interpolating to regular grid, creating new dfsu files
• Dfs012 analysis
