METHODOLOGICAL INFORMATION 
.................................

1. Description of the methods for collection/generation of data: 

- Numerical solutions for four-layer, shallow-water, steady, frictionless, and non-rotating flows. The fluid stratification and the channel geometry represent conditions of the Strait of Gibraltar.    

- Reference: Four-layer hydraulic models of the exchange flow through the Strait of Gibraltar (2025). Submitted to Journal of Physical Oceanography.

2. Data processing methods
-  No processing applied. 

3. Software or instruments needed to interpret the data:
- Matlab (under license). GNU Octave (open source). 

4. Standards and calibration information, if appropriate: 
- Does not apply.

5. Environmental or experimental conditions:
- Does not apply.
