Rehabilitation of the weir at Ahausen reservoir
After more than 60 years of operation, the fish-belly flap gates used for spilling floods had become corroded and therefore needed to be replaced. To stabilize the structure, ten anchors were installed in the dam.Tags: Rehabilitation/ Renovierung/ Bigge/ Ruhrverband/ Europ/ Deutschland/ NRW/ Ahausen
DAMS AND FLOOD CONTROL-SYSTEMS OF DETENTION RESERVOIRS IN SOUTHWESTERN GERMANY
One of the most significant benefits resulting from construction of a dam is the long-term and efficient protection that detention reservoirs provide against floods.Tags: Europa/ Baden-Württemberg/ Hochwasserschutz/ Safety/ Sicherheit/ Deutschland/ Flood Control

Hydraulic Simulation and Flood Protection in the River Basins of Kocher and Jagst, Germany
Both rivers originate in the gently hilled region of the Swabian Alb, which is located in south-west Germany. Because of the geological and meteorological situation, flood events in the Kocher and Jagst valleys mean large inundated areas.Tags: Europa/ Sicherheit/ flood control/ Hochwasserschutz/ Simulation/ Deutschland/ Baden-Württemberg/ Kocher

Realistic and Computational Efficient Evaluation of Temperature and Stress Development in Large RCC Dams
Based on comprehensive studies several new methods have been proposed and adopted in an effort to develop a more realistic and computational more efficient model for the temperature and thermal stress analysis of RCC dams.Tags: RCC/ Bauwerksüberwachung/ Temperature/ Stress Development
Groundwater Recharge in Wadi Channels Downstream of Dams Efficiency and Management Strategies
Groundwater recharge dams are used in arid countries to enhance the natural groundwater recharge by a controlled infiltration of stored flood events. The study is based on field tests in the Sultanate of OmanTags: Grundwasser/ Groundwater/ Asien/ Oman

New Developments in Dam Safety – Feasibility Evaluation on Risk
Today people become aware of the fact that all man made structures have a potential risk that has to be evaluated, assessed and managed. Thus the risk of dams is no longer neglected.Tags: risk/ safety/ Evaluation/ Deutschland/ Germany/ Risk Assessment/ Risk Management/ Risiko/ Sicherheit
Dimensioning of the design flood as part of a reservoir safety concept
Some basic ideas on safety analysis for reservoir dams and the related analytical tools are discussed, with particular reference to selection of the design flood. The author draws attention to some advantages of the probabilistic approach to risk analysisTags: safety/ risk analysis/ dam failure/ Deutschland/ Risiko/ Sicherheit/ Analyse
INNOVATIVE TECHNIQUES FOR THE REHABILITATION OF BAUTZEN DAM
In order to be able to guarantee the important supply functions, the Bautzen dam was taken out of operation for renewals. The project was divided into 12 subprojects, in order to tender the water level dependent and independent work out separately.Tags: Sachsen/ Bautzen/ monitoring/ flood control/ Hochwasserschutz/ Renovierung/ Betonversiegelung
