Human impact on rivers of central Europe

Timetable

The lectures will take place in the Institue of Geology, Faculty of Geographic and Geologic Sciences, 12 Krygowskiego Street on Fridays from 9.00 am to 10.30 am in room 64. The first lecture will take place on October 11.

The University Campus can be reached from the city center by Poznan Fast Tram (PST). You need to take tram line 12, 14, 15 or 16 and get off at "Os. Sobieskiego" final tram station. Then you need to take bus route 198 and get off at bus stop "UAM Wydział Geografii ". Please note the Institute of Geology is situated in a separate building, next to the main building of the Faculty of Geographic and Geologic Sciences. When you get off the bus you need go to the left. When you enter the bulding, please go stariaght on, then turn left and go along the corridor until you see stairs on your left. Go down the stairs and then go straight on along the corridor. The lecture room will be on your right hand slose to the end of the corridor.

Module aim (aims)

The main goal of the course is to present the influence of human-induced actions (i.e. constructions of canals, water dams, networks of drainage ditches) on changes in hydrological regimes, morphology of river channels and land-use within river valleys of central Europe. Another important goal is to show how river courses looked like before the period of intensive hydro technical works that started around 250 years ago. This will be presented showing the examples of river courses from Poland, Hungary, Croatia, Slovenia, eastern part of Germany, the Czech Republic, and other countries of central Europe. What research techniques can be used to reconstruct the evolution of rivers prior to the canals and dams constructions? How the knowledge about the past of rivers can be used in river restoration projects? All students of geography, geology, earth sciences, environmental management, hydrology, and spatial planning are warmly welcome to take this course.

Pre-requisites in terms of knowledge, skills and social competences (where relevant)

Basic knowledge about the natural environment of Europe.

Syllabus

Weeks 1 and 2: Introduction: main hydrological regimes, types of river channels (planforms)

 

 Weeks 3 and 4: Introduction (continued): types of human-induced changes (constructions of canals and dams, artificial levees, extraction of sediments from river bed), basic types of river reactions to these changes.

 

 Weeks 5 and 6: changes in land use within river valleys and their influence of the evolution of rivers

 

 Weeks 7 and 8: Overview of methods useful to reconstruct the evolution of past river systems, active prior to the major hydro technical works (geological methods, geophysical methods, analyses of aerial images, sediment dating techniques)

 

 Weeks 9 and 10: Examples of reconstruction of past river systems. Examples of the evolution of anastomosing, anabranching and meandering rivers of central Europe prior the constructions of dams and canals.

 

 Weeks 11 and 12: the use of palaeohydrological reconstructions for restoration projects: how to plan a realistic restoration scenario? Types of restoration plans/scenarios. Examples and reasons of failed restoration actions. Post-restoration monitoring of processes forming river channels.

 

 Weeks 13 and 14: Examples of dam removal actions and influence of these actions on hydrological and sediment transport regime. Advantages and disadvantages of dam removal. Reactions of society to restoration actions.
