Consolidated by the "Arbeitsgemeinschaft Trinkwassertalsperren" (ATT) six dam operators have developed two different benchmarking models which are based on different methodologies of benchmarking projects. These models demonstrate the advantages of benchmarking and are therefore not only interesting for drinking water dams but also for multiple-shift usage dams.

This article will focus on the technique of accurate and detailed airborne and terrestrial laser scanning. The advantages using a laser scanner, mounted underneath a helicopter, are shown. Since several years Airborne Laser Terrain Mapping is an economical alternative to survey large and inaccessible areas, where conventional methods are too expensive or too time-consuming.The empty reservoir of the Obermaubach Dam was scanned with the FLI-MAP® airborne scanning system. Terrestrial Laser Scanning has been proven by two applications: the deformation of a slope of embankment and the mechanical components of a weir plant.

The operation rules of the reservoir Olef have been adopted in order to integrate water quantity and quality management. A dynamically adjustable rule for flood control in combination with a quantity-quality based operation to preserve the Hypolimnion were established. The stratification of the water body in the reservoir Is calculated during May to September. If the Hypolimnion drops under a defined level, the discharge downstream is reduced to minimal tolerable values. The repeatedly calculation of the hypolimnion gives information of time and duration of the reduced discharge. As a result an increase of the 10 °C isotherm could be achieved. The operation time of the turbines decreased 11 % but power was reduced only with 4 %. Lower discharge during the summer stagnation is compensated to a certain level In winter and spring. The programme TALSIM is applied in the real-time operation at the reservoir.

The Inden opencast lignite mine is located some 20 km to the north-east of Aachen in Germany's Rhineland. After the end of lignite mining around the year 2030, a lake measuring some 11.8 km2 is planned to be created. It will mainly be filled with water from the river Rur flowing past in the immediate vicinity of the opencast mine. Filling the lake volume of some 800 million m3 will take 20 to 25 years. During the past ten years, the basic water management questions arising in connection with the creation of the Inden mine's residual lake were settled within the scope of the state-planning approval procedure. It could be demonstrated by means of a numeric river catchment model that the envisaged withdrawal of water from the Rur is feasible and compatible with the water body's ecological and hydromorphological targets as well as its industrial use.

Reservoirs are used to adjust naturally fluctuating river runoff to the needs of society. Flood waters are retained and stored water distributed reliably to water users. Operation rules for reservoirs are determined using the measured time series of inflows as boundary conditions. These conditions are likely to differ in the future due to climate change. A methodology is presented how reservoir performance can be analyzed for different climatic boundary conditions. Based on this analysis robust adaption measures can be found that perform well under current conditions as well as for a range of climate change scenarios. The method is applied to the Rur reservoirs.

The Rur Reservoirs are mainly serving for flood protection, drinking water supply, and water supply for industrial use in the Eifel-Rur region. Within a European INTERREG-IVB-NWE-project studies were conducted, how climate change could affect the reservoir management.


Recently commercial software packages and web based online-solutions have both become available for merging digital photos automatically to provide complete 3-D models. In a workflow, consisting of several steps, these 3-D models can be transferred into CAD software in general use. From this point it is possible to perform further functions such as scaling, dimensioning, calculating horizontal equivalents, volumes and areas etc. This study of a variety of objects from the service area of the Wasserverband Eifel-Rur, presents the method of 3-D surface modelling from photographic data (informally called Picture-Matching). Advantages and limitations are demonstrated.

Transboundary Water Management in a Changing Climate - Proceedings of the AMICE Final Conference | Year: 2013

There are many flood-water management constructions operating already in the Meuse river basin and more are planned in the next decades. Herein lie some big challenges. How to design new water management structures that are able to deal comprehensively with flooding, drought and increasing water demand. How to adapt existing flood control measures to cope with ever more extreme events. Through AMICE, new approaches to these challenges have been tested by three highly innovative projects in Germany, Flanders and the Netherlands. © 2013 Taylor & Francis Group.
