【 摘 要 】

In the framework of an industry-funded research project in the Dead Sea, Israel, the evolution and propagation of waves in a fluid with high density (brine) was investigated. In general, the density as well as the viscosity of water is neglected in wave theories and run-up formulas due to the fact that fresh water at 20 °C exhibits a density of 1 t/m3 and a dynamic viscosity of 1x10 kg/(m s). Yet, it is unknown how significant changes of these parameters influence the sensitivity of wave propagation and wave run-up on sloping beaches. Hence, this project follows the scientific approach to study the behaviour of a fluid, i.e. brine, stemming from the Dead Sea (Israel) with a density of 1.23 t/m3 and a dynamic viscosity at 20 °C of 3.4x10 kg/(m s). In a newly constructed wave (twin) flume with two separated channels wave kinematics and run-up of brine have been compared directly with fresh water wave kinematics and run-up.
