Syfte

The objective of the course is to provide fundamental understanding of the physical processes that determine the water flows and pathways in nature. The physics of the water movements are described and the relations between state and flows are quantified using mathematical expressions. The course is also to give an understanding of extreme events and the role of man on hydrology.

Mål

Kunskap och förståelse

För godkänd kurs skall doktoranden

• understand and quantify the relation between state and flow with relation to snowmelt, evaporation, infiltration and groundwater flow.
• understand and describe the water movements in a hill slope and the relation between high flows and the degree of water saturation in the soil.
• Understand the relation between groundwater and surface water.
• Be able to analyze extreme events.

Färdighet och förmåga

För godkänd kurs skall doktoranden

• formulate equations of snowmelt and compute the melt intensity.
• formulate equations for potential evaporation and compute real evaporation from vegetation and bare soil.
• compute soil water movement from given moisture conditions.
• compute time of concentration for different basins and different flow situations.
• compute water balance for different types of lakes and reservoirs.
• compute probabilities of extreme events.

Värderingsförmåga och förhållningssätt

För godkänd kurs skall doktoranden

• be able to present the basis for analyses and calculations, including simplifications and assumptions made, when formulating mathematical models; be aware of the uncertainties in the computations.
• in quantitative terms be able to communicate the results of analyses performed to a qualified group of stakeholders.
