Hydrology
Objectives
At the end of this course the student will have acquired knowledge, skills and competencies that allow:
- Define a watershed and identified is physiographic characteristics;
- Characterized the precipitation regime over a watershed;
- Calculate the evaporation from water bodies and the potential evapotranspiration from a region;
- Understand the infiltration, percolation and drainage process of water in the soil;
- Estimation of runoff, peak flows and corresponding water volumes;
- Calculate soil losses by water erosion and sediment transport by the runoff;
- 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 water resources.

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 exercise developed by the students.
Evaluation method
Requisites to obtain Frequency:
Mandatory attendance to Lab sessions – minimum of 2/3 of classes;
Development of six components project assignment, to be performed essentially during lab sessions.
Grades from 0 (minimum) to 20 (maximum).
Lab experiment reports (six): weight of 20% of final grade and mandatory to obtain frequency.
Two tests: weight of 40% each of final grade.
To obtain approval students must have a medium grade of 9.5 or superior in the tests.
