Juan José Leitón Montero

Hydrological Analyst

  • Tibás San José, CR
  • (+506) 8843 6048


I am a 28-year-old civil engineer with a strong background in mathematics, statistics, probability and methods of data analysis applied to hydrology and the abilities to lead and to communicate information effectively and efficiently. I am also capable of conducting research at multiple levels, working both individually or as part of interdisciplinary groups, thinking in abstract and coding in different programming languages. My main interests are programming, regionalization, probabilistic and statistical modelling, learning new languages and teaching.

Main projects

Report on hydrology and sediments for the Costa Rican river basins draining directly to the San Juan River

Conceptualizing, planning and conducting hydrological and sedimentological studies in the San Juan river basin in order to determine the average liquid and solid discharge regimes and to elaborate a detailed sediment budged for the main basin system using the Universal Soil Loss Equation (USLE).

  • Technical counseling to the Costa Rican legal team during the oral proceedings before the International Court of Justice at The Hague, The Netherlands (April 2015).

Methodology for the determination of adaptive flow

Regionalization of hydrological descriptors (mean annual runoff, variance, and flow duration curves) in three Costa Rican basins using the hydrostochastic interpolation approach.
