In June 1996, Porporato received the Arturo Parisatti International Price, awarded by the Istituto Veneto di Scienze, Lettere e Arti. He was Research Associate at the Texas A&M University (USA) in 1998 and Research Associate at Princeton University (USA), Department of Civil and Environmental Engineering, from 1999 to 2001.
His main research interests regard near-wall turbulence dynamics, nonlinear analysis of hydrologic time series, stochastic soil moisture dynamics and water balance, soil-atmosphere interaction, and ecohydrology.
Since 2004, Porporato is Editor of Water Resources Research (AGU) and has also been referee and reviewer for various international journals and agencies. He has been chairman and convener of the Ecohydrology sessions of the AGU Spring Meeting in 2001 and 2002 and of the EGU in 2004-2006. Porporato has been part of the Italian research groups of Turbulence and Vorticity and of Climate, Soil and Vegetation Interaction, an advisor for the real-time forecasting in the Piedmont Region.
Porporato's didactic experience comprises courses in Fluid Mechanics, Hydraulics, Hydraulic Constructions, Statistical and Physical Hydrology, Environmental Fluid Mechanics, Ecohydrology, Engineering Data Analysis, Nonlinear Dynamics and Stochastic Processes. He has also been the didactic coordinator for the International School "Hydroaid: Water for Development", co-organized by the Polytechnic of Turin and the Italian Ministry of Foreign Affairs.Porporato is author of more than 80 peer-reviewed papers, several publications presented at national and international conferences and invited talks. He is also co-author of the book "Ecohydrology of water controlled ecosystems" (Cambridge Univ. Press, 2004) and edited the book "Dryland Ecohydrology" (Springer, 2005).
