OVERVIEW

This repository contains the MATLAB code used as supplementary material for the thesis listed above. The code supports the processing and analysis of geomorphometric data and the subsequent statistical classification of watershed landscape characteristics.

The repository contains two supplementary materials:

1. Supplementary Materials 1 - Batch Geomorphometry Processing.mlx
2. Supplementary Materials 2 - HCPC Process.mlx


CONTENTS

Supplementary Materials 1 - Batch Geomorphometry Processing

This MATLAB code is used for the batch processing of geomorphometric data. It facilitates the automated processing of multiple datasets to derive the geomorphometric parameters required for the research analysis.

File:
Supplementary Materials 1 - Batch Geomorphometry Processing.mlx
Supplementary Materials 2 - HCPC Process.mlx

This MATLAB code implements the Hierarchical Clustering on Principal Components (HCPC) process. The procedure combines Principal Component Analysis (PCA) with hierarchical clustering to support the classification and interpretation of watershed landscape characteristics.
