The Departments of Anthropology and Civil and Environmental Engineering will host Jaime J. Carrera-Hernández, PhD, Professor of Applied Geosciences at Instituto Potosino de Investigación Científica y Tecnológica (IPICyT) in San Luis Potosí, México on August 4, 2010. Dr. Carrera is interested in the analysis of the impact that human activities have on the hydrological cycle and on the development of tools to analyze water management policies. He is also interested in the use of remotely sensed imagery for the development of physically-based, distributed hydrogeological modeling along with the use of Relational Databases for the efficient development of these models, as exemplified in the Basin of Mexico Hydrogeological Database (BMHDB). Carrera has applied some of these tools to estimate potential aquifer recharge in the Basin of Mexico and to analyze the impact that urban growth has had on aquifer recharge.
