Stability analysis for tidal inlets of Thuan An and Tu Hien using Escoffier diagram

Stability analysis of tidal inlets is very important in providing knowledge on the behaviour of tidal inlet and lagoon systems. The analysis results can help to plan and manage the system effectively as well as to provide information for stability design of the inlets. This paper presents a method of building and applying the Escoffier diagram...

Analytic solutions for flow in tidal inlets with tributary inflow

Hydraulic characteristics of flow in a tidal inlet act an important role in morphological changes of the inlet. In normal conditions, inlet currents flush sediment out of the inlet to maintain its opening against longshore sediment transports that tend to close the inlet. The currents in the inlet are contributed by the tides and also from...

Hydrodynamic modelling of tidal inlets in Hue, Vietnam

Application of an one-dimensional numerical model for hydrodynamic simulation of a complex lagooninlet system in Vietnam is presented. Model results help to get a better understanding on the behaviour of the system. Based on the numerical model results and analytic solutions, stability of tidal inlets is evaluated.

A Preliminary Study on Hydrodynamics of the Tam Giang - Cau Hai Lagoon and Tidal Inlet System in the Thua Thien-Hue Province, Vietnam

The Tarn Giang-Cau Hai lagoon is the most important coastal lagoon of Vietnam located in Thua Thien-Hue province. Basically formed in the late Holocene (more than 2000 years ago), the lagoon is being in the development stage. Its tidal inlets, nowadays are the Thuan An and Tu Hien inlets, are dynamic and ephemeral morphological features. Inlet...

Coastal inlets and tidal basins

lecture note: Tidal inlets and their associated basins (lagoons) are a common feature of lowland coasts all around the world. A significant part ofthe world's coastlines is formed by barrier island coasts, and most other tidal coasts are interrupted by estuaries and lagoon inlets. These tidal systems play a crucial role in the sediment budget...

Coastal erosion along the sand barrier: Case study in Hue, Vietnam

The problem in coastal erosion is wide spread in areas located in the coastal environment. However, in many developing countries, planning and coastal management have not gained much process due to several factors, one of which is the lack of understanding the influences in the coastal system. Vietnam is no exception to this problem. Located on...

Morphology an morphodynamics of the Wadden Sea

Geological and morphological description of the Wadden Sea, description of the present situation.

A review of morphological studies and models relevant for the Wadden Sea

This review presents brief summaries of a number of reports and mathematical models known to the author which may be relevant for short-term and long-term morphological developments of the Wadden Sea. It certainly is not a complete list of literature on this subject but it may guide other investigators working on this subject.

The dynamics of microtidal lagoons and adjacent coasts

We have formulated an aggregated-scale behaviour-model for the interaction between a tidal basin and its adjacent coastal environment, without adopting a priory assumptions about their independent dynamic equilibrium behaviour. Necessarily so, the model combines observations and findings resuhing from analogical model applications. The model...

A semi-empirical model of a tidal inlet system

Only in the last 25 years have coastal engineers begun to come to an understanding of the physical processes in and around tidal inlet systems. This lack of knowledge has caused tremendous surprises and problems due to unanticipated reactions of the system to changes caused by human interference. Examples of such interference are: (partial)...

Hydro-morphological study Douro estuary part 9: Hydro-morphological mathematical model

As a continuation of the initial study on the morphology of the Douro mouth, performed by Hydronamic in 1982, the Administracao dos Portos do Douro e Leixoes commisioned Hydronamic bv to construct a mathematical hydro-morphological model of the Douro mouth. This second part of the morphological study of the Douro mouth is divided into three...

Hydro-morphogical study Douro Estuary

The Administracao dos Portos do Douro e Leixoes is confronted with the fact that future expansion of the port area of Leixoes is limited by the surrounding hills and urbanization. One of the alternatives for future expansion might be the creation of port facilities in the Douro estuary, where a relatively large, flat area is available. However,...

Notes on tidal inlets on sandy shores

This report presents an edited collection of memoranda prepared over the past forty years on several aspects of inlet hydraulic and sedimentary characteristics, and is being published because of its general value to the GITI, as well as for its potential use in stimulating other researchers studying tidal inlets.

Planning and design of low-weir section jetty at Masonboro inlet, North Carolina

A berm and dune project for shore and hurricane protection was recently completed at Wrightsville Beach, North Carolina. A navigation project provides for a channel 14 feet deep and 400 feet wide through Hasonboro Inlet which forms the southern boundary of Wrightsville Beach. It has been found infeasible to maintain the channel by dredging alone...

By-passing and backpassing with special reference to conditions in Florida

By-passing by natural action is mentioned with special reference to Florida Inlets and to some other inlets in the United States and abroad. Natural by-passing at harbors on open shores is dealt with briefly. Present status of by-passing plant operations in Florida is reviewed. Inasmuch as it is evident that by-passing plants - partly because of...

Eb- en vloedschaar systemen in de Nederlandse getijwateren - Ebb and Flood channel systems in the Netherlands tidal waters

The present paper, "Eb- en vloedschaarsystemen in de Nederlandse getijwateren" (Ebb- and floodchannel systems in the Dutch tidal waters), which was published in 1950, should be considered as Van Veen's most important publication since his thesis. It summarizes the results of 20 years of intensive study of estuarine and tidal-basin morphodynamics...
