Objectives
Knowledge of methods taught in the scope of the discipline, towards a theoretical and practical approach of problems and questions regarding Hydrology and quantitative analysis of the water resources forum.
Introduction to the basics of water resources management.
Prerequisites
Lab sessions attendance (minimum of 2/3) and accomplishment of 6 lab exercises (6 reports).
Subject matter
Hydrological cycle: general subjects; hydrological balance.
Watershed analysis: delimitation; phisiographic characteristics.
Precipitation: classification; precipitation intensity and depth; statistics and hydrology.
Interception: concept and processes.
Evaporation: concepts; measurement; calculation; factors that influence evaporation.
Evapotranspiration: concepts; potential and effective evapotranspiration; potential evapotranspiration.
Flow in the saturated and the unsaturated zone.
Hydraulic conductivity. Darcy’s law.
Infiltration, percolation and drainage.
Surface runoff: river flow measurement; hydrological series; reservoir dimensioning; watershed runoff components; hydrographs; flooding; urban surface runoff.
Water resources managemnt: demanwater demand and availability; reservoir design and operation.

Teaching method
Lectures: presentation of the concepts and correpondent implementation techniques in Hydrology.
Labs: presentation and exemplification of techniques, instrumentation and informatic tools in Hydrology; accompaniment of lab exercises developed by the students.
Evaluation method
Student’s evaluation from 0 up to 20 points, according to the evaluation and weighing of a theoretical and a practical component, each evaluated according to:
1 - Theoretical component - Two written tests - 35% each, adding to a total of 70%
Written tests have a 2 hours maximum duration and will include distinct matters presented in lectures. Tests will take place during the semester. This evaluation can also be obtained through a final exam.
2 - Practical component - 6 group practical works - globally representing 30% of final evaluation.
Group tasks are mainly developed during practical classes and 6 corresponding reports must be delivered for evaluation.
3. Frequency of the course requires meeting the following mandatory requisites:
a) Minimum of attendance of 2/3 of practical sessions
b) Delivery of 6 group reports
Each Frequency component is valid for the present and following school year.
4. Final evaluation
Final evaluation (NF) requires a minimum of 9,5 in each of the evaluation components, theoretical (NT) and practical (NP). Final grade is calculated according to:
NF = NP x 0,3 + NT x 0,7
