HydroClimatology LAB

Welcome to HydroClimatology LAB- Decomposing Complexity developed by Ankit Agarwal at the department of Hydrology IIT Roorkee!!


WWW.hydroclimx.com

The lab focuses to study the interactions and variability of natural processes, synchronization of extreme events (climatic/hydrology) at different spatial and temporal and even cross-scales. Our research shows the flavour of earth system dynamics, climate physics, stochastic hydrology, wavelet analysis, ensemble modelling, climate variability studies and some of its extension parts as regionalization technique, hydrologic classification and related subjects. A few of the tools that we use are network theory, event synchronization and wavelet.
