Andy Tranmer’s research addresses the physical processes of complex aquatic systems and their respective influence on ecological resilience for the purposes of responsible alluvial design and river restoration. A greater understanding of the physical mechanics occurring in the riparian corridor allow for prediction of geomorphic evolution, habitat suitability and ecosystem performance to guide sustainable resource management and public policy. A complementary suite of field, numerical and laboratory studies are employed to further the current state of knowledge in these dynamic environments. Recent work in Idaho assessed reservoir operations to guide floodplain sustainability and endangered species recovery. International projects examined pristine fluvial networks in Chilean Patagonia and large-scale flume experiments in Korea to quantify transport mechanics during alluvial channel evolution.
