Beyond sand and water: Opportunities for the continuous social, structural and morphological transformation of Puntarenas

The city of Puntarenas in Costa Rica is one of the many examples along the country’s pacific coast, where settlements have developed and survived by the extraction/exploitation of marine resources and the chain of industries that follow. Currently, these coastal communities are being affected by an amount of socio-economical issues, some...

Using small scale morphological features on estuarine tidal flats as indicators for large scale morphological shape and development

Intertidal flats and salt marshes can protect hinterland against wave energy and flooding by tides or storm surges. Thus, the development of tidal flats is important to foresee. The presence of specific small scale features could indicate a certain development and large scale morphological shape. The shape is a predictor for development and it...

Stability of morphological cells to dredging-dumping activities

The Westerschelde estuary in the South-West of the Netherlands displays two meandering flood and ebb channels separated by shoals. The system of flood, ebb channel and shoal between two channel crossings form a morphological cell. The stability of the serial cell system formed by the Westerschelde is important for the navigation route to the...

Morphodynamics of estuarine navigation channel

The port of Kandla, which is situated in the north west of India and is subject to a large tidal variation of about 5 metres, is preparing a major expansion plan. The capacity of the harbour will be increased in two ways. Firstly the construction of several berths and jetties will allow more ships to be handled on a yearly basis. Secondly...

Haringvlietmonding: Op zoek naar evenwicht: Morfologische ontwikkelingen van de Haringvlietmonding sinds 1970

Het Haringvliet is een zeegat dat deel uitmaakt van het Deltagebied. Vanaf 1950 zijn er een aantal grote ingrepen gedaan in de monding van het Haringvliet, zoals de aanleg van de Maasvlakte en de Slufterdam en de bouw van de Haringvlietdam met spuisluizen. Door deze ingrepen is de hydrodynamische situatie en daarmee de morfologie ingrijpend...

Two dimensional sedimentation modeling in the Port of El Tablazo

Due to increasing dredging costs, especially in ports and estuaries where the bed often contains contaminated substances, an increased tendency is observed to the investigation for more structural solutions to prevent deposition. Before however applying such engineering schemes a thorough knowledge of the sediment dynamics is needed. In the...

Interaction between the Yellow river and its estuary

The 5,464 km long Yellow River (Chinese: Huang He) is the second longest river of the Peoples Republic of China. Its source is in Qinghai-Tibet Plateau and empties after serving an agricultural population of over 126 million people in the Bohai Bay. The main characteristic of the Yellow River is the extremely high sediment load which causes the...

Morphological modelling of ebb and flood channel systems in estuaries

The morphological behaviour of estuaries is complex and at present (1995) not well understood. Ebb and flood channels play an important role in the morphological behaviour of an estuary. In order to get more insight in the morphological behaviour of such systems it is studied whether a 1-D morphodynamic network model gives insight in this...
