Material for day first (January 7 2021) - Catchment delineation and Geomorphology

 You can download the material for day first (January 7 2021) from this link.

After unzipping the folder you can see the typical structure of a OMS project. This is better explained in this previous blogpost. If you are reading this in advance, please take a little time to understand what OMS is and why it is like this.

During day 1 (7 Jan 2021) we will focus on the geomorphological analysis of a river basin. Starting from a digital elevation model we will extract the main river basin and we will split it the hillslope-link structure appropriate for executing the GEOframe models. All the material come with the .zip file, however, for your convenience, the slides are also available separately at the link below.

 The theoretical part of the class in subdivided in three parts:

•   Principal geomorphological attributes theory 

• Principal gemorphological attributes practice

• Principal derived quantities and river network extraction

• Principal derived quantities with the Horton Machine

• Watershed Partitioning

• Watershed partitioning in practice

• A python script is also available for some additional work on maps (waiting for the definitive HortonMachine Tool). The python script is PyQGIS.py

For the exercises

In the OMS3 project distribute you will find:

•    data, a folder containing the model input

•    simulations, a folder containing the scripts for executing the models.

•    doc containing the pdf of the lectures

•    Jupyter containing a group of notebooks which illustrate the inputs and outputs of the simulations

What the other folders contain is explained  in the OMS3 related post (see The OMS working environment).

Further information on the tools used and reference to the material of the previous Winter Schools can be found here.
