Mr Emilio Echevarria

PhD Student

University of Tasmania


Emilio is has worked under the supervision of Prof Neil Holbrook and Dr Mark Hemer since July, 2017. His PhD is funded by UTAS and CSIRO. Emilio is from Argentina, where he did undergraduate studies in Physical Oceanography at the University of Buenos Aires. He did his Honours thesis with the Coastal Dynamics group of the Hydrographic Navy Service of Argentina, studying the sediment transport produced by the waves in the sandy beaches of the Buenos Aires province.

THESIS: Global to coastal implications of surface current modulation of the wind-wave field

Wind-generated surface ocean waves play a very important role in many oceanic processes, such as the longshore transport of sediments, changes in the coastline position, the Stokes drift (an important consideration for search and rescue activities), exchanges of heat, mass and momentum through the air-sea interface, among many others. They are also important for engineering projects such as the construction of coastal structures, off-shore activities or the planning of shipping routes require accurate predictions of the wind-wave climate. The Intergovernmental Panel on Climate Change (IPCC) has stated that changes in wind-wave climate will have broad implications for the operation and design of coastal, near and off-shore industries and ecosystems, and may further exacerbate the anticipated vulnerabilities of coastal regions to projected sea level rise. Emilio will investigate the influence that ocean currents have on the waves’ propagation (i.e. changes in wave height, period, direction, etc). Having a model that accurately represents the wave climate, taking into account all the different processes that may be affecting them, is crucial to study the long-term tendencies of wave parameters and to make accurate predictions of its maximum values. He will perform global wave simulations of the WAVEWATCH III model forced with and without surface currents, and then study the differences observed. He will also pay a special attention to the Tasman Sea region and assess how the East Australian Current modifies the wave climate in this region.
