(2) Learning Outcomes
Learning Outcomes
By the end of this course the students will acquire a knowledge of hydrological processes in different terrestrial environments; a knowledge of hydrological monitoring and modelling techniques and their app During the course the students will learn the theory and the basic principles governing the science of hydrology. They will understand the main components of the hydrological cycle through a series of examples that contribute to the understanding of theoretical concepts. Drought indicators, flood models, climate characterization indicators will be among the basic tools they will understand and will be able to apply to each study area.
The calibration, verification and analysis of a hydrological simulation model, as well as its use for the creation of management scenarios, will be the main tool for synthesizing the acquired knowledge, developing the crisis and understanding hydrological systems.
The use of practical tools such as scientific literature and IT tools for creating, analyzing, editing and writing works will also be enhanced. Students will learn to check the time, following the delivery dates.
General Competences
Understanding the hydrological cycle and hydrological processes
Hydrological data analysis and its visualization for decision making
Synthesis of the acquired knowledge
