Drainage (Laboratory)

The aim of the lesson is to present, to inform and to educate students on issues related to additional water removing in a specific area. This water could be over the soil surface or underground with the main purpose to make the area more suitable for use by humans. Also basic aim is the economotechnical investigation in different techniques used in rendering process of drainage and the effect of different parameters involved in the study of a drainage network.

Objectives

Upon successful completion of this lesson the student : • has demonstrated knowledge and understanding of issues relating to soil drainage networks, design, organization and construction method. • is able to use the knowledge and understanding in a way that shows professional approach to work, to have skills proved by developing and supporting arguments and solve implementation problems of soil drainage. • is able to notify ideas and solutions to problems related to crop irrigation at both specialist and non-specialist audience. • has developed those skills to learn in order to continue his/her study in high level in a particular subject.
