Rhine Water

Effluents from point sources (industries, communities) and diffuse inputs introduce pollutants into the water of the river Rhine and cause a basic contaminant load. The aim is to establish a biological warning system to detect increased toxicity in addition to the already existing chemical-physical monitoring system. To cover a wide range of biocides, continuous working biotests at different trophic levels (bacteria, algae, mussels, water fleas, fishes) have been developed and proved. These are checked out for sensitivity against toxicants, reaction time, validity of data and practical handling under field conditions at the river. Test-specific appropriate methods are found to differentiate between the normal range of variation and true alarm signals.

Micro Organisms

Production of drinking water from river water, abstracted either directly from river or from storage reservoirs, requires the application of barriers for pathogenic micro-organisms. About one third of the total production of drinking water in the Netherlands is derived from surface water, mainly the River Meuse and branches of the River Rhine. The results of extensive monitoring programmes show that the microbiological water quality of the River Rhine and River Meuse is strongly influenced by domestic and agricultural waste water discharges, with respect to the River Meuse mainly in the Liège-region in Belgium. Densities of Cryptosporidium and Giardia in both rivers are comparable; the highest density was found in the Belgian Meuse basin. Elimination rates of 1.7- to 3.1 10log-units for pathogenic micro-organisms were found in Dutch storage reservoirs, which can thus be considered as an important first barrier for pathogenic microorganisms. The elimination capacity of reservoirs is influenced by retention time and contamination by waterfowl. To meet the proposed quality criteria for pathogens in drinking water, however, additional barriers are required.

Summary For more than five hundred years the southern part of the Netherlands belonged to the Roman Empire, more particularly to the province of Germania inferior (Lower Germany). The left bank of the river Rhine served as the external boundary of this province, once the ambition to annex the Germanic territories across the river had been abandoned. Although the Lower German Limes is only a modest part of the whole frontier system of the Roman Empire, it can boast of various distinctive characteristics, the most important of which is the outstanding preservation of timber buildings, ships and other organic remains in the water-logged conditions of the Rhine delta. This paper presents a brief history of this frontier section and addresses a few general issues, as an introduction to a series of papers discussing a variety of aspects of the frontier and of life in a frontier zone.

The Relation between Vegetation and Hydrology/Geomorphology in the Gemenc Floodplain Forest, Hungary

River Danube

In the Gemenc floodplain along the river Danube in Southern Hungary, six vegetation zones have been identified. Together with soil and geomorphological data, these vegetation zones are interpreted to form a hypothesis of succession for the Gemenc floodplain. As the Gemenc floodplain is comparable with the Dutch floodplains, from a hydrological, geomorphological and floristic point of view, the results can be used in plans for the rehabilitation of the floodplains of the river Rhine in the Netherlands.

AbstractShortly after the river Rhine enters the Netherlands, it bifurcates into three branches. A predefined, fixed discharge distribution over the bifurcation points is vital, since the dikes are designed with a predefined distribution in mind. Recent observations show that the discharge distribution that is anticipated at design discharge conditions differs from the predefined one. One of the goals of the national program Room for the River is therefore to restore the discharge distribution. To control the hydraulic processes during flood events, the construction of two adaptable spillways in the direct neighbourhood of the bifurcation points is proposed as a possible solution. The spillways are capable of maintaining the proper discharge distribution. They can also act as regulators during the construction phase of the flood managements plans of the project Room for the River. Hence, the discharge ratio and thus the water levels are such that the safety-standards are not violated. The morphological consequences are most probably very small, provided that strong erosion during flood events can be prevented and the autonomous bed degradation stays within reasonable limits.
