This study explores the influence of the wave characteristics on the attenuation process of waves through coastal mangroves, which are threatened by the coastal mangrove squeeze phenomenon. Coastal mangrove squeeze is the phenomenon where coastal regions, even when sediment availability is sufficient, are eroding due to a lack of accommodation...

Verhagen, H.J. (author)
In this paper, protection options for a high-value, industrial area along the coast of West Bengal (India) are investigated. The options are designed to protect against cyclone surges with a probability of 1/100 per year. Two alternatives are compared, a classical solution of a dike with a revetment and a solution with a mangrove belt in...

Truong Hong, S. (author)
Mangroves are an interesting species of vegetation, surviving and thriving at the interface of land and water, in the inter tidal brackish coastal waters between the mean sea level and mean high water. Mangroves are a highly productive and complex ecosystem, providing numerous services and goods to people and marine environment. Mangroves are...

Dao, T.; Stive, M.J.F.; Hofland, B., and Mai, T., 2018. Wave damping due to wooden fences along mangrove coasts. In the Mekong Delta, as in many other mangrove settings, wooden fences are considered beneficial coastal structures to provide sheltering for mangrove replantation efforts by reducing waves and currents and promoting sedimentation....

Mangroves have proved to be an asset to coastlines owing to their various advantages in terms of coastal protection and stability. Along tropical coastlines, as mangrove tracts recede and threats of coastal erosion mount, mangrove rehabilitation projects are being seriously contemplated. The design of such projects, however, is in an incipient...

In this paper the typical hydrodynamics on mangrove-mud coasts are studied. Worldwide, these coasts experience serious erosion problems, and while the importance of mangrove ecosystems is becoming widely recognised, mangrove restoration projects frequently fail due to poor understanding of the system, especially the hydrodynamics. Therefore, a...

During recent decades, mangrove forests have experienced severe degradation due to unsustainable land use. Restoration of mangrove ecosystems requires the recovery of their habitat, considering ecology, hydrology, hydrodynamics, and sediment transport. In a first pilot in 2013, brushwood dams were built on the eroding coast of Demak, Indonesia,...

Mangroves are extremely important from the ecological and socio-economic perspectives, but are degrading at an alarming rate nowadays. Besides direct clearance, hydrological alterations or climatic changes, chemical pollution could be a significant contributor of mangrove degradation. To understand chemical pollution in mangroves, the input and...

Indonesia is home to the largest area of mangrove forests in the world. Urban expansion, aquaculture farms, oil-palm plantations and timber extraction have caused an estimated decline of about 1.2 million hectares of Indonesia’s mangroves since the 1980’s, and currently only 3 million hectares remain. The major cause of mangrove conversion is...

Tusinski, A. (author), Verhagen, H.J. (author)
The objective of this research is to obtain generic relations between attenuated wave heights and various vegetation and topographical scenarios. Subsequently, it is aimed to find out what is the actual cost profit of a dike construction behind a mangrove zone comparing to the case when mangroves are absent. The graphs and formulas developed in...

Coastal ecosystems such as mangroves can reduce risk to people and infrastructure from wave damage and flooding. The continued provision of these coastal defence services by mangroves is dependent on their capacity to adapt to projected rates of sea level rise. This report explores the capacity of mangrove soil surfaces to increase in elevation...

Storm surges occur when high winds and low atmospheric pressure raise water levels at the coast, causing sea water to surge onto the land. They are a major threat to low-lying coastal areas and their inhabitants. The largest storm surges are caused by tropical cyclones (also called hurricanes and typhoons in different regions); peak water levels...

Verhagen, H.J. (author)
Apart from many ecological advantages, mangroves in front of a coastal defence may lower the construction and maintenance costs of the defence. Although mangroves have hardly any reducing effect on water levels (and on tsunami impact) mangroves may significantly reduce wave attack on a coastal dike, and in this way reduce the cost of a revetment...

Coastal populations are particularly vulnerable to the impacts of extreme events such as storms and hurricanes, and these pressures may be exacerbated through the influence of climate change and sea level rise. Coastal ecosystems such as mangrove forests are increasingly being promoted and used as a tool in coastal defence strategies. There...

A study of the effectiveness of mangroves in attenuating cyclone- induced waves was done using the SWAN 40.81 numerical model. Hydraulic parameters during extreme events and local mangrove vegetation parameters were estimated for the Kanika Sands mangrove island near the upcoming Dhamra Port in Orissa, India. Simplified generic analyses were...

Marchand, M. (author)
In Vietnam mangrove rehabilitation has a long history and gained momentum after the war that destroyed huge forested areas, especially in the Mekong Delta. In addition, in various places mangrove have been and still are being planted specifically as a way to protect shorelines and sea-dykes from wave attack. The success of such projects highly...

Schiereck, G.J. (author), Booij, N. (author)
There is an increasing awareness of the role of mangrove forests in coastal ecosystems and coastal protection. At the transition between ocean and land, they have to absorb the energy that comes from the motion of the water. Little quantitative in formation is available, however, on wave transmission in these forests. In this paper the...

Taal, M.D. (author)
An analytical mathematical model is presented for flow and salinity in tidal mangrove swamps that is based one-dimensional approaches. The model is designed with the purpose to develop a method for rapid assessment of effects in mangrove swamps due to changes in river discharges that can also be used in situations with few data. A literature...

Mangroves are productive ecosystems, that sustain important fisheries, provide a variety of forest products and harbour millions of resident and migratory birds as well as endangered mammals and reptiles. Reclamation for aquaculture and agriculture is currently considered the main way to achieve development of mangrove areas. These types of...
