NPLK14023U Applied Agrohydrology
The objectives of the course are to obtain advanced and
applicable knovledge on agrohydrological and soil
physical properties and processes at the field scale
affecting plant production and the environment. Quantification
of properties and modeling of sub-processes being important
prerequisites for achieving these goals will be put in focus when
Topics: Water in soil: hydraulic properties (water retention and hydraulic conductivity, models and model parameterizations). Soil structure: fundamentals and implications (e.g. for water, gas, heat and solute transport); principles of structure management (soil tillage). Evapotranspiration (resistance theory, estimation of reference and actual evapotranspiration, crop water demand, water balances, effects on microclimate). Water flow in soil: fundamentals; crop water uptake, soil evaporation, infiltration, drainage, soil water balance. Design principles for drainage works at field scale and at larger scales; implications of artificial drainage (crop production, environment). Transport of contaminants in soil, leaching: fundamentals and selected cases representing inert, non-adsorbing, sorbing and degradable substances. Non-equilibrium transport, effects of preferential water flow. Field scale variability: spatial variability and how to deal with it.
Course report: each student prepares an individual course report (typically 10-15 pages) and submit it to the course responsible before the examination. The report documents (examplifies) and combines the application of central methods and theory in an analysis of self-selected or given problems within the framework of the course.
Knowledge, skills and competences obtained during the course:
Knowledge: Students understand (can explain) all fundamental laws, principles, model concepts and methods presented during the course.
Skills: Students can apply and combine the presented methods and principles to characterize the soil-plant-atmosphere system as a basis for evaluation of effects on crops and the environment.
Competences: Students can identify and analyze the most important agrohydrolocical and soil physical factors in relation to their primary focus, interpret the results of their analysis and draw the relevant conclusions.
The study materials include specialized advanced textbooks, specialized review papers, simple computer models, and original research papers
- Theory exercises
- 7,5 ECTS
- Type of assessment

Criteria for exam assesment
Criteria defining the perfect exam performance are specifyed under "Learning Outcome". To obtain the assessment passed, the students must show both knowledge, skills, and competences without major weaknesses in more than two areas.
