Hydraulics and Hydrology (WSE/02/c)

Entry requirements for WSE

• To familiarise participants with the main concepts of steady/unsteady and uniform/non-uniform flow.
• Understand the principles and basic equations of water flow and enable participants to apply them to various practical situations.
• Be familiar with basic measurements in the wave and current flumes at the hydraulic laboratory.
• Be familiar with the concepts of hydrology need for each specialisation.
• Understand the concepts of Geographical Information Systems and have experience of how to use them.
• Understand the main techniques of remote sensing and know when their use is appropriate or inappropriate.

Free-Surface Hydrodynamics (N. Wright, S. Maskey, L. Hayde, L. Brandimarte)
Development of hydrodynamic equations as well as their applications to uniform and non-uniform flow and different methods of solution. Steady flow situations: uniform flow in channels; shear stress distribution; velocity distribution; logarithmic profile. Sub-critical and supercritical flows. Non uniform flow; rapid and gradually varied flow; computation of water surface profiles. Flow through hydraulic structures, Unsteady flow: equations of Saint-Venant, methods of solution, kinematic and diffusive waves, flood waves, tidal channel flow. Overland flows: main channel/floodplain interaction.
Hydraulics Laboratory: various types of measuring equipment. Choice of various flow types: over a broad crested weir, through a contraction, underneath a gate; wave propagation and dissipation in a flume.

Engineering Hydrology (S. Uhlenbrook, P. de Laat)
Hydrological cycle, water balance, catchment, water divide, influence of man, rainfall measurement, areal rainfall, depth-duration-frequency curves, types of evaporation, evaporation equations, infiltration (formula of Horton), soil moisture, groundwater, measurement of water level and discharge, flow duration curves, rainfall-runoff relationship, rainfall-runoff analysis, Rational Method for estimating peak discharge, unit hydrograph method.
Workshop exercises on extreme value distribution, data completion/double mass analysis, hydrological modeling

Geographical Information Systems and Remote Sensing (Z. Vojinovic, Z. Vekerdy and others)
Introduction to geographic information systems and remote sensing technologies; active and passive remote sensing; data structures, map projections and coordinate systems; processing of digital geographic information; creation of digital elevation models; visualisation, mapping of water and environmental features; watersheds, streams and aquifers delineation; digitisation, soil and land use mapping; map algebra; terrain analysis for hydrological and hydraulic modeling; production of thematic maps; GIS as a decision support tool.
Exercise and assignment using a case study data.
Software: ArcGIS 9.
