2. WATER RESOURCES HYDROGEOLOGY, HYDROLOGY AND WATER RESOURCES MANAGEMENT • DESCRIPTION • We study the integrated water cycle and its interaction with natural and human environments, with the purpose of developing and applying tools to model and assess the spatial and temporal variability of water resources, and use them in planning, design and managing operational systems and infrastructure. Our main research areas include: • Surface hydrology: Hydrologic processes in natural and urban catchments, hydrologic-geomorphologic-ecologic interaction, spatial variability in rainfall erosivity and water erosion processes • Stochastic hydrology: Modeling and characterization of floods, droughts and other extreme hydrologic events • Hydrogeology: Groundwater and pollutant transport modeling, geostatistical applications for groundwater, surface-subsurface interaction in arid and semi-arid regions • RESOURCES • Computer laboratories and equipments for fieldwork • Research budget through grants • Research agreement with governmental organizations and private companies with interests in water resources PRINCIPAL INVESTIGATORS: Bonifacio Fernández, PhD José F.

FLUID MECHANICS AND HYDRAULICS RIVER AND COASTAL ENGINEERING PRINICIPAL INVESTIGATORS Rodrigo Cienfuegos, PhD Cristián Escauriaza, PhD POST DOCS Rafael Almar, PhD GRADUATE STUDENTS PhD: Leandro Suárez Mauricio Villagrán MSc: Juan Carlos Domínguez Maricarmen Guerra Nils Lindeen Boris Rodríguez Doménico Sciolla Tomás Olivares DESCRIPTION We develop advanced tools for applications in hydraulic and coastal engineering focusing on flow hydrodynamics, transport and mixing processes at different scales in aquatic environments. We carry out fluid dynamics research for a wide range of applications in engineering analysis and design, sediment transport and erosion in fluvial and coastal regions, transport and mixing of passive and active substances, transport of slurries in industrial applications, and renewable energy. Our group seeks to study and propose solutions for engineering applications based on deep knowledge of the physical mechanisms that occur in nature.
