Day 3. Danube Excursion: Passau—Linz

by Lea Wiser


Passau → Linz


Our third day on the Danube excursion was both eventful and thought provoking, packed with activities covering a broad range of subjects: from environment and sustainability to modern history and the Nazi regime, to where these two subjects intersect—the city of Linz.

Jochenstein

Our first stops, the Donaukraftwerk in Jochenstein and Haus am Strom in Untergriesbach, were already familiar to us, but during this visit we were able to admire the views from the other side of the Danube. On the way, we passed the Schlögener Schlinge, a meandering part of the river that created a loess-rich agricultural land below the steep slopes of the Bohemian Massif.

Day 2. Danube Excursion: Deggendorf—Passau

Bridge-Building and Nature Conservation on the Donau

Early Modern Bridges and Politics in Bavaria

On the second day of our field trip, we learned about Early Modern bridge-building in Bavaria. Martin Keßler’s talk focused on the politics of bridges, using as an example the bridge of Vilshofen, a small town near Passau. In the Middle Ages, Passau was an autonomous bishopric, independent from the duchy of Bavaria and archbishopric of Salzburg. It maintained its autonomy from Bavaria until 1802. Early Modern Bavaria included the lands between the rivers Lech to the west, the Danube to the north, and the Inn to the east. Within the territory of Bavaria there were many other stand-alone territories, for example imperial free cities like Augsburg and Nuremberg.

Day 1. The Danube Excursion: Munich—Deggendorf

Written by David Stäblein

The bus ride from Munich to Deggendorf along the Isar river

The landscape en route from Munich to Deggendorf is dominated by the flat valley of the river Isar. The river has carried a lot of material from the Alps to the lower part of the river near Deggendorf. This is the reason the soil here consists of an eight-meter-thick layer of river sediment. The Isar valley is surrounded by hills, in a landscape where erodible brown soil has been heavily deposited. The colluvium from this landscape, combined with the river sediments, makes the area the perfect place for agriculture (primarily sugar beet and corn). The Mühlbogental is an area near Deggendorf which has become the focus of concentrated industry; here lies a paper mill, as well as a BMW production site that was built on subsidies to discourage migration out of the region.

To the south of Deggendorf the Isar flows into the Danube (Donau in German), which was, in former days, only constrained in its meandering by the Bavarian Forest (a cool, infertile, and mountainous range dominated by gneiss) in the north east. Today, many dikes bound the naturally wandering landscape of the Danube, and the ancient current is limited by a row of hydropower plants spanning the whole of the Danube’s course through Bavaria. Together, the hydropower plants in Bavaria produce around 15 percent of Germany’s electricity supply. All the best spots for these plants have been occupied, which means that the expansion of hydropower is only possible if the plants become more efficient (to reach the goal of 17 percent). The flood defenses around Deggendorf were first installed in the 18th century and have since been expanded and modernized. Throughout the year (especially around June and August) numerous small flood events (below HQ 30) hit the area, but the dikes and polders usually prevent severe damage to surrounding communities.

Winding through Central and Eastern Europe, the once longstanding frontier of the Roman empire, the Danube, has carved its way into the landscapes and cultures of the countries it traverses. But the marks of humans, imprints of the Anthropocene, are also clearly visible on the river itself—and on the ecologies and landscapes surrounding it. By uncovering and reading landmarks across time and place, the interactions between societies and rivers can be recounted from different perspectives as multifaceted environmental histories.
