## Research Context

This kernel is used for the **KALYPSO-1D (or KALYPSO-WSPM)** module of the software platform [KALYPSO](https://sourceforge.net/projects/kalypso/) for stationary, one-dimensional simulations of the water level in flowing water bodies. It applies methodological approaches in accordance with DVWK Merkblatt 220 and BWK Merkblatt 1/2000.  

Among other things, this module is also used to prepare water body sections for further transient, one-dimensional simulations in KALYPSO-1D2D.

## Installation

1. Install the latest release of KALYPSO from [https://sourceforge.net/projects/kalypso/](https://sourceforge.net/projects/kalypso/).  
2. Copy the compiled kernel `Kalypso-1D.exe` to the WSPWin program directory, e.g.:  
   ```
   C:\WspWin\bin
   ```
3. Enter the name of the current `*.exe` in the first line of the configuration file `wspbce.cfg` (also located in the WSPWin program directory).  
4. (Optional) Copy the file `Polynome1d_2.3.1.exe` to the WSPWin program directory, e.g.:  
   ```
   C:\WspWin\bin
   ```

**Remarks:**  
`Polynome1d_2.3.1.exe` is used to create three descriptive functions (Q, A, a) per profile as functions of the water depth H. It is based on steady-state calculations over a discharge interval (Qmin to Qmax).
