Two fields, water and structures, work together in the lab to manage infrastructure smartly.

AboutAbout the lab
A lab merging water and structures
The International Environmental Infrastructure Management Lab studies ways to manage infrastructure smartly.
The lab combines two fields: a water field that examines how climate change affects hydraulic structures using long-term hydrological data, and a structural field that extracts information on structural health from bridge vibrations.
In the water field, the lab combines machine learning with hydrological models to predict rainfall and river water levels and to project water resources under climate change.
In the structural field, the lab analyzes bridge modes from the vibrations produced by everyday traffic to detect damage that cannot be seen.
Key terms
- Hydrological data
- Data obtained by measuring and recording the water cycle, such as precipitation and river discharge
- Global Climate Model (GCM)
- A model that calculates the movements of the atmosphere and oceans across the whole Earth to project the future climate
- Modal parameters
- Values intrinsic to a structure, such as the shapes and periods of its natural vibrations when it shakes. They serve as clues for finding damage hidden in a bridge

ResearchResearch themes
This is an interdisciplinary lab made up of a water field, which analyzes how climate change affects hydraulic structures using long-term hydrological data, and a structural field, which extracts information related to structural health from the vibration responses of bridges. The lab aims to manage infrastructure smartly.
*Illustrative imageWhat Drives Monsoon Rainfall
The lab combines the classification of synoptic-scale weather patterns with nonlinear machine learning methods that measure feature importance, and builds a framework for understanding and predicting precipitation variability in the Asian monsoon region.
*Illustrative imageClimate Change and Water Resources Management
Using the output of Global Climate Models (GCMs), the lab examines changes in precipitation patterns and in water resources in key river basins. It identifies problems that may arise now and in the future, and develops and proposes solutions.
*Illustrative imageReading Floods with Weather Radar
Using precipitation data observed by weather radar and distributed hydrological models, the lab carries out short-term rainfall forecasting and flood forecasting. It studies non-structural measures that reduce flood risk without relying on structures, such as real-time flood forecasting.
*Illustrative imageFinding Bridge Damage from Traffic Vibrations
Focusing on detecting damage hidden in short- and medium-span bridges using vibrations from everyday traffic, the lab investigates effective damage indicators such as modal parameters and spectral functions.
