MIKE IO 1D: Read MIKE 1D in python

Read, manipulate, and analyze res1d, res, resx, out, and xns11 files.

For other MIKE files (Dfs0, Dfs1, Dfs2, Dfsu,...) use the related package MIKE IO

Most users of MIKE IO 1D will also find MIKE+Py of interest.

Requirements

• Windows, Linux (experimental)
• Python x64 3.12 - 3.14
• (Windows) VC++ redistributables (already installed if you have MIKE)
• (Linux) .NET Runtime (not installed by default)

Installation

From PyPI:

pip install mikeio1d

Linux users will need to install .NET runtime. For Ubuntu, you can install .NET runtime as follows:

sudo apt install dotnet-runtime-8.0

Or development version:

pip install https://github.com/DHI/mikeio1d/archive/main.zip

If you're on the development branch, you need .NET SDK. Ubuntu users can install these dependencies as follows:

sudo apt install dotnet-sdk-8.0

Documentation

Check out the official documentation for MIKE IO 1D.

Getting started

Read network results into a DataFrame

>>>  import mikeio1d
>>>  res = mikeio1d.open('my_results.res1d')
>>>  df = res.read()

>>>  df_reach = res.reaches['my_reach'].Discharge.read()
>>>  df_node  = res.nodes['my_node'].WaterLevel.read()

Read Xns11 file and plot a cross section

>>>  import mikeio1d

# Plot section with location id 'basin_right', chainage '238.800', and topo id '1'.
>>>  xns = mikeio1d.open("mikep_cs_demo.xns11")
>>>  xns['basin_right', '238.800', '1'].plot()
