“…If a node depth is less than 3.0 m, its depth is set to 3.0 m; the bottom drag coefficient C d is calculated from equation (2). The mangrove zones are treated differently from the water areas and tidal flats due to the larger drag forces caused by mangrove trees and their roots [Mazda et al, 1997]. According to field experience and Mazda et al [1997], C d ranges from about 1.0 to 10.0 depending on the observation site, mangrove species and tidal conditions.…”

[1] The tidal dynamics of Darwin Harbour, Australia, are simulated using a finite volume coastal ocean model. The calibrated model agreed well with the observed sea surface elevation and current velocity. Results indicate that the harbor's hydrodynamics are driven mainly by the tides, with wind and river inputs playing only small roles. The M 2 tide is dominant, with amplitude 1.7 m and peak current speed 3.0 m s À1 . Sensitivity tests using the model indicate that the mangrove areas and tidal flats play crucial roles in modulating tidal amplitudes and phases in the embayments, especially for the shallow water tides such as M 4 . Removal of the mangrove areas and tidal flats from Darwin Harbour would dampen the M 2 amplitude due to decreased shoaling effects but generate a 75.0% greater M 4 amplitude in parts of the harbor. Mangrove areas and tidal flats also affect tidal asymmetry through the changing amplitudes and phases of mainly the M 2 and M 4 tides. In Darwin Harbour, tidal asymmetry, measured by elevation and current skewness, would increase by up to 100% if the mangrove areas were removed. If the tidal flats were removed as well, the increase would be 120%. Therefore, reclamation of the mangrove areas and tidal flats may cause sediment siltation as a result of increased flood dominance. Although this study is site-specific, the model and our findings have a wider applicability to the effects of mangrove areas and tidal flats on tides and sediment transport in harbors and estuaries.

“…However, if we consider that coastal protection afforded by mangroves depends on their functional ability to attenuate storm waves (18)(19)(20)(21) and that this relationship is nonlinear ( fig. S1A), a different EBM strategy is supported (Fig.…”

“…According to Massel et al (1999), mangroves can absorb 75% of wave energy when passing through 200 meters of mangroves. Mazda et al (1997) estimates that a 1.5 km belt of mangroves can fully attenuate energy from the waves of 1 m. Sundarban mangroves support extensive fishery by providing habitat and protection for fish breeding and nursery for fish and shellfish (Beck et al 2001;Lee 2008;Hussain et al 2014). In Southeast Asia 30% of fish and 100% of prawn catches are mangrove-related species (Ronnback 1999).…”

Mangroves provide valuable ecosystem services for the wellbeing of coastal communities. Assessment and valuation of these mangroves services are increasingly advocated in development and conservation decision-making. Translating the values of services into more explicit monetary terms requires understanding of stakeholder activities, socio-economic context and local organizational structure to effectively support decision-making. Based on a survey of 100 households of three villages of Sundarban in Bangladesh, mangroves services to local communities were identified and their economic values estimated. The households perceived 18 mangroves services, of which capture fisheries, fuel energy, storm protection, habitat for fish breeding and nursery grounds and aesthetic enjoyment were
