Hydrological Modelling

Data and data quality. GIS systems in hydrological applications. Lumped and distributed precipitation - runoff models. Updating and inflow prognosis. Reservoirs and lake models. Modelling of rivers and flood zones. Modelling of ungaged basins and regionalisation. Snow hydrology. Simulation of land use changes.

Knowledge

The student should have knowledge of:

• How hydrological models can be used for planning and operation of power plants, flood simulations and land use changes.
• Theoretical foundation of the models
• What simplifications and approximations that must be made for practical use
• Which input required, uncertainty and errors in the data, and methods for correction
• Calibration, Uncertainty and evaluation of results.
• Use of GIS in hydrological modelling
• The course gives an in depth introduction to using digital tools in hydrology, the development, application and evaluation of output.
• The course gives an introduction to tools and methods for a sustainable use of water resources.

Skills

Students will be able to:

• Calibrate and use rainfall-runoff models to calculate drainage in a catchment
• Calculating snowmelt with a degree day model and an energy balance model
• Setup and application of a distributed model.
• Prepare and assess the quality of data from different sources

General competance

Students can:

• Link between basic hydrological theory and application of models
• Choose between which problems that may be solved with simplistic models, and which require more complicated models
• Understand how GIS can be used for hydrologic and hydraulic calculations

Lectures and seminars. Guided exercises and applications of computer models. 8 out of 12 exercises must be approved for access to the exam.
