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.

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.

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.

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.

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.
