Modeling in Water Management

NRB014 course is part of 1 study plan

Ing. full-t. program NPC-SIV compulsory-elective Summer Semester 1st year 5 credits

Introduction to modelling of processes in water management (classification of problems, initial and boundary problems, definition of the model, state variables). Direct and indirect modelling (direct and inverse problems), principles of continuity and determinism, philosophy of stochastic modelling. Basic equations of fluid and structural mechanics (mass conservation, momentum and energy conservation, equations of state). Strain-stress problems in water management, local and global stability, limit states. Principle of virtual works, finite elements method, thermal stress. Selected problems of seepage hydraulics, relaxation method, transient flow, phreatic surface solutions. Dam break modelling due to overtopping and internal erosion. Modelling of advection and dispersion of matter (mathematical formulation, steady and unsteady models). Balance and dynamic models.

Learning outcomes

The result is the ability of graduates to classify problems in water management in terms of modelling, to demonstrate approaches at deriving governing equations in water related disciplines (mass and energy balance, momentum conservation, equations of state) and to specify boundary and initial conditions. The course deals with strain-stress problems, seepage hydraulics, dam break modelling and pollution transport in open channels.

Prerequisites

Mathematics, Hydraulics, Statics, Strain and stress analysis

Corequisites

Numerical methods, statistics

Planned educational activities and teaching methods

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations. The seminars are held in computer laboratory.

Forms and criteria of assessment

100% presence in seminars, exceptionally 2 seminars - apologized, for exam the credit is necessary, for positive evaluation at least partial knowledge in each of 3 questions

Objective

The aim is to classify hydrodynamical problems in terms of mathematical modelling, to demonstrate approaches at deriving governing equations in fluid mechanics (mass and energy balance, momentum conservation, equations of state) and to specify boundary and initial conditions. The course deals with laminar and turbulent modelling, open channel and floodplain hydraulics and groundwater flow.
