This reports gives insight in the results of the exerpiments done with Ground Condolidators. This report will focus on the tests that evaluate the proposed execution method. In this execution method, the Ground Condolidators will be placed in batches (with help of a clamshell) on the bed to create a mattress. This mattress will slow down the...

Modelling contaminants in the Sungei Buloh Wetland Reserve using Delft3D-WAQ results in useful data on residence times. Since measurements in the field are often not possible due to either safety hazards or ecological implications, the water quality model provides comprehensive data to analyse the behaviour of flow and contaminants and with that...

Modelling tidal dynamics in mangrove systems is of great use in studying effects of vegetation on flow and may prove to be a useful tool to support the management of mangrove areas. Since there are lots of limitations on obtaining field data inside mangrove forests, numerical models are indispensable to analyse the effects of changes in mangrove...

Wave transmission is a very important design parameter for submerged porous breakwater design, as it defines the dimensions of the breakwater as well as the cost and construction process. The spatial distribution of the wave transmission parameter influences the current pattern on the lee of the breakwater and therefore the sediment transport...

This thesis focusses on the north-eastward shifting beach at Brouwersdam, which poses a problem for users and stakeholders of the beach. This trend is likely to continue in the foreseeable future and could result in a beach that can no longer fulfil its current functions, like recreation and tourism. Analysis of bathymetric data from the last...

Wind waves are capable of dealing damage to hydraulic structures. In the ultimate case, the loads never exceed the strength of the structure. Unfortunately it is often impossible (or uneconomical) to design a structure that will fit this requirement. That is why structures are designed with a certain allowable probability of failure, displayed...

Comparison of measured overtopping data with computations with Swash. The SWASH output discharges are smaller than the 5% lower limit of Eurotop and Neural Network predictions. Nevertheless, they were close values and they have the same order of magnitude, which is very important when comparing overtopping values. No refection analysis was done....

The main goal of this study is to determe the relation between very oblique wave attack and overtopping, and to accordingly adjust the formulae for oblique wave attack. The required knowledge to be able to read and understand this report is of a Bachelor in civil engineering level. All around the world different types of structures are built to...

This thesis focuses on wave overtopping at rubble mound breakwaters with a non-reshaping berm. The research was aimed at gaining insight into the influence of a permeable berm on the overtopping behaviour. Moreover it was desired to validate existing prediction methods for the spatial distribution of overtopping for breakwaters with a non...

Breakwaters are used for reducing wave height in harbours or divert sediment. One of the types of breakwaters is the rubble mound breakwater. These structures are constructed with smaller quarry rock as core and larger quarry rock as outer layer. For economical reasons, the design allows some damage to the armour layer. The amount of damage is...

Scour formation at the toe of a rubble mound breakwater can lead to abrupt failure. Nowadays, counteraction of scour via geometrically closed filter rules, geotextiles or combinations is the common practice. Alternatively, in specific cases the use of geometrically open filters can save significant amount of time and decrease constructional...

Mangrove forests have been proven to be an efficient system in attenuation of the wave energy. Therefore, they may be incorporated in the construction of coastal dikes and contribute to decreasing the total cost of such a project. This may be achieved by lowering the dike crest, lesser usage of the land or applying softer revetments. Each...

Breakwaters are important objects to protect coastal- and harbour areas. To minimalize the probability of failure of breakwaters, a lot of research has been conducted concerning the stability of breakwaters. After Iribarren and Hudson, an influential research is conducted by Van der Meer. The literature research of this report will provide more...

The dimensions of single layer concrete armour units (interlocking armour units) are calculated with a similar stability relation as the stability relation for quarry stone. In these design formulas an 'average/significant' wave load is used (Hs). Since quarry stone gains its stability only from gravity, this type of armour unit is constructed...

Although the effect of wave attenuation by mangrove has been widely observed and studied, the problem pertaining to how to accurately describe the geometrical properties is still remaining unresolved. Also, the material properties of mangrove root have not been comprehensively studied before. This is study is dedicated for the survey on...

According to the future development plan, discharge sluices will be constructed at three main branches of Tien River to prevent salinity intrusion. To evaluate the consequences of these constructions to the Mekong Delta Estuaries, the empirical relationship between tidal prism and river cross-section is estimated in this study. It is found that...

Granular filters are used for protection against scour and erosion. For a proper functioning it is necessary that interfaces between the filter structure, the subsoil and the water flowing above the filter structure are stable. Stability means that there is no transport of subsoil material through the filter to the water above the filter, and...

Richards Bay Port, located in the East Coast of South Africa, was built during the 1970s. Two rubble mound breakwaters were constructed to protect the deep-water entrance channel and create a sheltered area for the vessels. Since the completion of these breakwaters in 1976, they have withstood several major storms, including cyclones that have...

For this project, Environment Mapping & Surveying (EMS) from South Africa has provided two pressure meters for wave measuring. These pressure meters give a value for the pressure, which must be converted to pressure and after that to a Rayleigh distribution and a wave spectrum. Therefore is the purpose of this report to test the pressure meter...

Interlocking, single layer concrete armour units are placed in a specific grid depending on the type of armour unit. Within this grid, armour units are placed in horizontal rows. The number of horizontal rows of single layer armour units on a breakwater is limited to 20. This limit is proposed in order to prevent major settlements, which might...
