Hidrologia e Obras de Drenagem

On this curricular unit, students will shall acquire knowledge skills and competences to characterise the reference conditions of natural hydrological phenomena and their degree of anthropic modification. They will also be able to contribute to the testing and simulation of planning and management options for water systems, namely those associated with drainage problems and flow regulation and storage (using hydraulic works). Students will thus be able to do:

• Watershed delimitation and watershed physiographic characterization;

• Process hydrometeorological raw data (from gage capture to the hydrometry of flows);

• Make statistical characterization of precipitation's regime in a watershed or at a rain gauge station;

• Perform water balances through the quantification of the components of the hydrological cycle such as precipitation, evaporation, evapotranspiration, infiltration and surface runoff;

• Understand infiltration processes and soil water drainage;

• Calculate surface runoff and flow volumes in a downstream section;

• Evaluate water needs and availability in a watershed;

• Understand and use methods for flood peak flow calculation in rural and urban watersheds, dimensioning curverts to cope with drainage problems;

• Characterize the intensity-frequency-duration of rainfall episodes and their erosive potential.
