  • Estimate the time distribution of maximum flow.

  • Determination of ecological water demands in lakes and wetlands with the objective of determining the necessary appropriations for the maintenance and restoration of Lakes and Wetlands taking into consideration climate conditions, hydrological properties and the typology of the ones already mentioned..
