DESIGN OF ADAPTIVE HYDRAULIC STRUCTURES (DESSEIN PRÉPOSITION ADAPTER HYDRAULIC STRUCTURER

As dawn breaks on the 21st century, humanity is confronted with three fundamental problems that are interrelated in a complex system: water crisis, flood mitigation and development of sustainable projects. In view of these challenges, rapid construction of cost - efficient and safe hydraulic structures is vital. On the other hand, hydrosystem changes have resulted in uncertain design parameters. Consequently more efficient approaches should be adopted for design of hydraulic structures. Solution of these problems will above all require adopting a holistic approach emphasizing the importance of the whole and the interdependence of parts for development of adaptive design strategies. The system of hydraulic structures consists of hardware (structures) and software (management and knowledge). The interdependence of structural and non-structural approaches in design is not well established in spite of the fact that it can reduce the hardware substantially. Using numerous researches and worldwide experience, interdependence of various disciplines of design, construction and operation of hydraulic structures is established and the strategies of the holistic design are developed. Holistic design is based on comprehensive management and flexibility. Accordingly design of the management would be a priority. Continuous monitoring of the hydrosystem and structures is the key to coping with uncertainties of design parameters and consequently seasonal characteristics and forecasting can be incorporated into the design. Continuous management and flexibility would make continuous design feasible. In view of certainties and economical considerations, during extreme events far larger than design parameters, the structures should be designed to enhance safety. As the last line of defense, safe evacuation of people and property should be ensured. Integration of these strategies would result in reduced structural dimensions and increased safety. Worldwide experience clearly demonstrated that overlooking of these fundamental principles has produced most of the failures, accidents and problems of the hydraulic structures. In the last 10 years, numerous case studies studied not only verified the effectiveness, adaptability and versatility of KURIT but also confirmed the validity of the strategies of the holistic design
