Moses-Kelvin/Niger-River-Morphodynamics-Dashboard

Interactive dashboard visualising 25 years of channel morphodynamics in the Kainji-Jebba reach of the Niger River using Landsat, RivMAP, and RivGraph. # Niger River Morphodynamics Dashboard An interactive web dashboard exploring **25 years of channel morphodynamics** (2001–2025) in the Kainji–Jebba reach of the River Niger, Nigeria. --- ## Table of Contents - Overview - Research Context - Features - Tech Stack - Data Sources - Installation - Data Processing - Project Structure - Deployment - License - Acknowledgments - Citation - Contact --- ## Overview This dashboard visualises satellite-derived metrics of river channel change downstream of the Kainji and Jebba dams. It combines: - **Planform metrics** – Width, sinuosity, and migration rates (RivMAP) - **Network metrics** – Braiding index and secondary channel proportion (RivGraph) - **Land cover** – Water, vegetation, and bare land area (Random Forest classification) - **Climate data** – Annual rainfall (CHIRPS) - **Spatial layers** – Segment boundaries and river masks (Landsat-derived) The dashboard is designed to support researchers, water resource managers, and policymakers in understanding the long-term geomorphic response of a large regulated tropical river. --- ## Research Context The Kainji (1968) and Jebba (1983) dams regulate river discharge and trap sediment in the upper Niger River. This study investigates whether: 1. The main channel planform has changed (RivMAP) 2. The river network has simplified (RivGraph) 3. Rainfall explains observed changes (Spearman correlation) ### Key Findings | Metric | Segment 1 | Segment 2 | |---------|-----------|-----------| | Channel Width | Stable | Stable | | Sinuosity | Stable | Stable | | Braiding Index | Stable | ⬇️ **Decreasing (p = 0.047)** | | Total Network Length | Stable | ⬇️ **Decreasing (p = 0.047)** | | Secondary Channels | Stable | ⬇️ **Decreasing** | The downstream segment (Segment 2) is progressively losing network complexity, with secondary channels disappearing while the main channel remains relatively fixed. --- ## Features - 📊 **Summary Cards** displaying key morphometric …
