“…In the Amazon region, this model was successfully applied to simulate estuarine regions hydrodynamics (Oliveros et al, 2008), the evolution of anabranching structures (Frias et al, 2015;Mendoza et al, 2016). It has also already been applied to model FP (Hostache et al, 2014;Smolders et al, 2015) and other large rivers (Vu et al, 2015).…”

Flooding dynamics across a medium-size (Janauaca Lake, 786 km 2 ) floodplain system along the Amazon/Solimoes River over a 9-year period (2006-2015) is studied through integration of remote sensing and limited in situ data in hydrologic-hydrodynamic modelling based on Telemac-2D model. Model accuracy varies through the hydrological year. We focus on seasonal and interannual spatial variability of water circulation and inundation duration. We highlight strong heterogeneities in water velocity magnitude between the different morphological domains of the floodplain, the highest velocities being encountered in the river-floodplain channel. In addition to topography, we emphasize the importance of the main channel and the local runoff in controlling the water circulation, at least during part of the hydrological year. From low water to early rising period, local runoff constrains the river incursion across the floodplain, while the rates of main channel rising/receding controls the flood duration. The comparison of several hydrological years highlights the interannual changes of these hydraulic controls and also the influence exerted by prior inundation conditions. While we observed few changes in water velocity distribution among hydrological years, the inundation duration is highly variable. Usually defined by maximum water level, extreme flood events may paradoxically induce positive (up to 40 days) but also negative (up to −20 days) anomalies of inundation duration.

“…The maximum result value of tidal measurements was equal to 1.30 meters and the minimum value obtained was 0.67 meters. After tidal results were obtained for fifteen days, the data were analyzed by using the Least Square method [7]. The results of the Least Square method in Pekalongan fishing port were presented as follows.…”

Pekalongan River has two functions, i.e., as fishing boat transportation and the main drainage of Pekalongan City. The Pekalongan river estuary has a Jetty located on two sides of the river mouth. The jetty is used to protect from waves and sediment. The Pekalongan river has upstream flow from Kupang and Banger river. Because of the flood incident around 2003, Since 2014, the two rivers became two estuaries. The condition caused a negative impact on sediment in the river mouth. Therefore, this research aims to find solutions by simulating waves, currents, and sediments. In this paper, the focus is on the wave simulation. This research method begins with the collection of primary data in the form of bathymetry measurements at the river mouth. While the secondary data is wind data for 13 years and tidal. Calculation of wind hindcasting figures out a wave at a significantly high value of 1.38 m and a significant period of 4.80 seconds. For wave simulations, it used SMS software in the CGWAVE module. The simulation compares the two jetties condition, in existing and development conditions. Based on the simulation, the wave is still high for existing conditions and becoming low by an extended jetty of 200 m lengths. The simulation results can be used to analyze the movement of sediment transport that is affected by the movement of waves around the river mouth.

“…Ecosystem adaptation is therefore being considered more often as a mechanism to increase a system's resilience (Brown et al, 2011). One example of such a solution is coastal wetlands, which are recognized for their ability to lessen storm impacts and absorb flood water (Smolders et al, 2015). In response to economic growth within a changing coastal climate alternative solutions to flood and erosion risk management are emerging.…”

Abstract. Storms across the globe and their associated consequences in coastal zones (flooding and erosion), combined with the long-term geomorphic evolution of our coastlines, are a threat to life and assets, both socioeconomic and environmental. In a changing climate, with a rising global sea level, potentially changing patterns in storm tracks and storminess, and rising population density and pressures on the coastal zone, the future risk of coastal storm impacts is likely to increase. Coastal managers and policy makers therefore need to make effective and timely decisions on the use of resources for the immediate and longer term.Research focused on "monitoring and modelling to guide coastal adaptation to extreme storm events in a changing climate" is becoming more common; its goal is to provide science-based decision support for effective adaptation to the consequences of storm impacts, both now and under future climate scenarios at the coast. The growing transfer of information between the science community and end-users is enabling leading research to have a greater impact on the socioeconomic resilience of coastal communities. This special issue covers recent research activities relating to coastal hazard mapping in response to extreme events, economic impacts of long-term change, coastal processes influencing management decisions and the development of online decision support tools.
