Tropical Hydrology: Modeling and Field Experimentation
Session ID#: 81117
Session Description:
The tropics are well-known for their major role in the global cycles of water, carbon, and nutrients. The extreme spatial and temporal variability of hydrological processes in these regions results in high uncertainties and a poor understanding of water and material fluxes, storage and groundwater recharge across different scales. Extremes such as droughts or intense rainfall events are often evidenced.
The observational hydrology is declining despite its relevance to develop and validate new hypotheses, and models need better approaches for data assimilation. The collection of data in the tropics faces great challenges mostly due to economic and political aspects and, therefore, modeling and novel observational techniques have been increasingly applied as alternatives to develop cutting-edge research.
In this session, we invite modelers and field experimentalists with contributions on how hydrological processes are shaped by time-invariant factors and time-varying controls as well as hydrological prediction and ecosystem interactions in tropical regions.
