Dr. Arenas is a Principal Civil Engineer with 25 years of experience in geotechnical engineering. He has
led important geotechnical and structural designs, such as Concrete Faced Rock Dams (CFRD),
Mechanically Stabilized Earth (MSE) walls, waste dumps and tailings storage facilities. He has
conducted Dam Safety Review (DSR) assessments and TSF inspections. Additionally, he has assessed
slope stability and liquefaction potential for a multitude of projects. He has conducted seismic hazard
analysis, including spectral matching of real seismic events and has conducted several dam breach
analyses.

 
He has been the leader for numerical modelling in the civil and mining sectors, having developed this
role in south America and Australia. He has led a multitude of analyses using FLAC/FLAC3D. He has
modelled static and dynamic conditions, incorporating liquefaction potential analysis and cyclic
compaction, using advanced constitutive models. He has developed a series of methodologies for
delivering numerical analyses in a such a way that allow for the delivery of results in a short time and at
reasonable low cost. Finally, he has developed a standalone software for producing high efficiency
meshes for FLAC and FLAC3D within few hours. He has worked for different client sectors, including
numerical analyses for NASA, forensic analyses of civil structures under litigation, governmental
institutions and important mining projects.
