DEMONSTRATION OF THE SYLLABUS COHERENCE WITH THE CURRICULAR UNIT'S OBJECTIVES:
The increasing use of geosynthetics to replace natural materials in civil engineering works associated with the low cost of these materials, simplicity of application and contribution to reducing the environmental impact are important factors to present appropriate techniques of design, application and quality control of geosynthetics in different types of civil engineering works.
This course aims to relate the theoretical classes with the theoretical-practical/practical ones, so that students can easily be acquainted with the themes of the course. Additionally, it will be used slides and movies (real situations), in order to clarify the themes of the course.
DEMONSTRATION OF THE COHERENCE BETWEEN THE TEACHING METHODOLOGIES AND THE LEARNING OUTCOMES:
The used teaching methodologies allow to deal with main themes related to application of geossynthetics in civil engineering, analysis, discussion and critical interpretation of results, emphasizing the potential of writing communication, problem formulation and certification.
