In this exercise you will complete the setup of a case to run with SERGHEI. We will use a well known benchmark case for shallow water models which reproduces a laboratory scale experiment of the [tsunami which hit the Monai valley](https://nctr.pmel.noaa.gov/okushiri_devastation.html) in the Okushiri island, just west of Hokkaido, Japan in 1993. The SERGHEI setup follows a well established [benchmark](https://nctr.pmel.noaa.gov/benchmark/Laboratory/Laboratory_MonaiValley/index.html).
In this tutorial, we don't discuss all the details of how to setup a model with SERGHEI. However, you can take a look also at [another tutorial](https://gitlab.com/serghei-model/serghei/-/wikis/User-Guide/Quick-tutorial:-setup-a-model) concerning the whole setup process for more details.

This tutorial assumes that you have built SERGHEI and have managed to run some simple test case before.
#1. Get some data
#2. What do I need to set up?
SERGHEI requires, a minimum set of 3 input files:
* a Digital Elevation Model (DEM), which must be named `dem.input`
* a simulation control file called `parameters.input`
* a shallow water model control input file `sw.input`
However, many other files can be defined. A tutorial on the input files is [here](https://gitlab.com/serghei-model/serghei/-/wikis/User-Guide/Quick-tutorial:-setup-a-model).
In the data which you cloned you will find the `dem.input` file with the experimental scale bathymetry and topography of the affected region. This is an ASCII raster file. You can inspect it by simply opening it as a text file.
Generating an appropriate DEM is a job in itself and will not be discussed here.
You also get a `wave.input` file containing a time-series definition of the input wave which serves as a forcing boundary and drives the tsunami into the computational domain.
