Design Water Level | ScienceGate

In designing coastal protective structures the knowledge of the static load due to the water level elevation is as important as that of the dynamic load due to the waves. The structure, designed at sandy coasts with well formed surf zones on the beach - these areas are the basis of this examination - has to stand against both, the superposition of the static and dynamic load, which are dependent on each other. Undoubtedly a rise in the design water level (a summation of different influences - see figure 1) will cause an increase in the wave heights and the reverse will happen, when the design water level decreases.

Design Water Level

The determination of diversion risk in the construction of water conservancy and hydropower projects is a key problem related to the guarantee of project safety, saving project investment, giving full play to benefits in advance and facilitating construction. According to the design data, considering the influence of the uncertain factors such as hydrology and hydraulics, this paper analyses the relationship between the elevation of the upstream cofferdam and the upstream design water level, uses the Monte Carlo method to simulate the construction flood process and the discharge capacity of the diversion buildings, makes statistical analysis and determines the risk corresponding to the upstream water level distribution of the cofferdam and the water retaining height of the cofferdam, and establishes the calculation model of the construction diversion risk.

Design Water Level

In coastal areas, high water levels often result from a combination of events such as high tide and high flow. For such areas, design engineers often have to estimate the water level that would be exceeded with a specified probability. Several methods, including the traditional ad-hoc way, of making such estimates are compared for simple situations, where it is possible to obtain exact answers by numerical integration. Key words: floods, flood probability, combined probability, probability estimation, design water level.

Design Water Level

In this study, hydraulic model tests were performed to investigate the stability of armor units at harbor side slope for rubble mound structures. The Korean design standard for harbor and fishery port suggested the design figures that showed the ratio of the armor weight for each location of rubble mound structures and it could be known that the same weight ratio was needed to the sea side and harbor side (within 0.5H from the minimum design water level) slope of rubble mound structures. The super structures were commonly applied to the design process of rubble mound structures in Korea and the investigation of the effects of super structures would be needed. The stability number (Nod = 0.5) was applied (van der Meer, 1999) and it showed that the armor (tetrapod) weight ratio for harbor side slope of rubble mound structures needed 0.8 times of that for sea side slope.

In this paper, design water level elevations due to wave, tide, wind and barometric pressure are calculated in hotspots including the ports of Kong, Lengeh, Shahid Rajaiee, Kuhmobarak, Sirik and Khuran. The effect of global water level rise is also considered. This modelling is performed utilizing MIKE21 developed by DHI Water and Environment. In order to calculate wave and tide setup, comprehensive and exhaustive studies of wave propagation and tidal levels modelling, which have been performed in last parts of Monitoring and Modeling Project of Coastal Zones of Hormozgan, are used. Also, wind-induced water level variations model is developed to calculate wind setup in various return periods. The results of the study present values of setup due to above mentioned phenomena which can be used in marine structures designs.
