Introduction to WG activity

The overall scope of the International Association of Geomorphologists (IAG) working Group: Tropical Rivers -Geomorphology, Impacts, Hazards and Management is the study of morphodynamic processes in tropical rivers and to provide an integrated assessment of long-term direct impacts of climate variability and human-induced change and management of tropical rivers basins by identification, quantification and modeling of key hydro-geomorphologic indicators during the past and present times. The potential impacts of global change on fluvial systems and of their socio-economic implications and flood hazards are also analyzed. Several of the largest and many of the most vulnerable rivers of the world are located in the equatorial and monsoonal region as well as some of the most active areas of fluvial sedimentation and erosion of the planet. We welcome in this working group contributions on the Quaternary history, morphodynamics, hydro-geomorphology, hazards and management of tropical rivers.


Activities 2015

  • AGU-FALL MEETING SAN FRANCISCO, DECEMBER 2015. EP53D: Fluvial Morphodynamics: Channels Patterns, Process-Based Unsteadiness, Tropical Rivers, and Beyond II. – This session is co-organized by our Tropical Rivers WG

Recent Activities

  • River Coastal and Estuarine Morphodynamics-RCEM-9th Symposium

The International Association of Geomorphologist ( IAG) Working Group on Tropical River organized a special session  in the 9th Symposium on River, Coastal and Estuarine Morphodynamics, RCEM 2015, Iquitos City, Peru (August 30 to September 3, 2015).  The session had thirteen oral presentations plus a poster session. Results from the Amazon, Magdalena, Fly, Negro, Parana, Mitchell (Australia), Ucayali, mountains rivers from Costa Rica and others were presented. Prof. Latrubesse (UT-Austin) also offered a one day field course titled The Amazon River from late Tertiary to present: paleogeographic reorganization of the basin, Quaternary record and present morphodynamics

A new special session will be organized during the XI SINAGEO, National Symposium of Geomorphology of the Brazilian Union of Geomorphology (UGB), Maringa PR, September 2016.

A new special issue on Large Rivers with emphasis on Tropical Rivers is under preparation for the flag journal Geomorphology
