Hydro Regen: Regenerative Hydrology Platform

Overview & Objective
An interactive decision-support and geospatial visualization platform built in a 48-hour sprint during the Aquathon hackathon. Won 3rd Place overall and the prestigious 'Coup de Cœur' Jury Award from the Office International de l'Eau (OiEau). Inspired by the regenerative hydrology paradigm introduced by Prof. Karl Matthias Wantzen, the platform empowers regional stakeholders to explore watershed regenerative potential ('bassins versants'), define custom intervention polygons, identify drought and flood vulnerability zones, and simulate ecological water retention scenarios.
The Vision: Regenerative Hydrology
Traditional water management treats water as an extractive resource or a risk to channel away as fast as possible through concrete infrastructure. Regenerative hydrology—championed by Professor Karl Matthias Wantzen—inverts this logic: it focuses on slowing, spreading, and sinking rainwater into the soil to recharge aquifers, restore natural humidity cycles, and revitalize local micro-climates. Hydro Regen translates these scientific principles into an intuitive digital decision-support tool.
Geospatial Web Application Features
Interactive Watershed Selection
Geolocate or search addresses to load watershed basin boundaries ("bassins versants") with hydrological flow data.
Custom Polygon Drawing Tools
Empowers municipal decision-makers to outline specific plots of land and simulate re-naturalization impacts.
Ecological Intervention Simulations
Simulates the retention capacity gained through swales, retention ponds, urban de-paving, and agro-forestry buffers.
