“…Reduced complexity model is more suited in geomorphology terms where it focuses more on the particular area of interest that are crucial to describe a situation (Walkden and Hall, 2011) which is well suited for the assessment of potential coastal management solution (Walkden et al, 2015). Previous studies have been carried out that successfully integrate this two modelling approach into one overarching framework (Nichollas et al, 2012). Accordingly, this study adopts the approach of reduced complexity model as a backbone in correctly representing the overall hydrodynamics in the model in combination with reductionist model in representing sediment dynamics and management solution prediction.…”

a b s t r a c tThe dynamic nature of a river channel entrance is commonly seasonal dependant. This is evidenced in the topography of river channel entrances in East Coast of Borneo which is influenced by both North East (NE) and South West (SW) monsoons on top of surrounding parameters such as waves and tides, sedimentation as well as climate change. Advanced numerical modelling technique is frequently used as a leading approach to investigate the complicated nature of river channel entrance to well represent actual conditions of a designated area. This paper presented a mesoscale numerical modelling method by integrating reductionist and reduced complexity model approach along with local seasonal conditions to well represent river channel entrance problem and propose management measures. The model was established with a set of numerical equilibrium equations and calibrated parameters to reflect the features of regional conditions with the combination of local validated modelling parameters. The model had accurately represented the effects of both NE and SW monsoons in terms of hydraulics and sediment dynamics at the Petagas river channel entrance, as verified by site data and satellite imagery. In addition, the accuracy of the model provides confidence in the implementation of improvement measures at the river channel entrance. The improvement scheme includes a training channel and a breakwater in improving flushing capacity, thus preventing sedimentation and upstream flooding, allowing proper navigation through the river. In conclusion, the accurate investigational result from this numerical model had successfully demonstrated its scientific role in solving dynamic river channel entrance, which can serve as a numerical modelling approach for solving similar river channel entrance problems especially in the East Coast of Borneo with predominant inter-annual seasonal variations.

“…In East Anglia, a broad span of projects of note have been undertaken focusing on coastal change and risk, combining stakeholders and multiple academic organisations. Two significant studies, which have partially focussed on the area have been the 'Tyndall Coastal Simulator' project (Mokrech et al, 2011) and subsequently 'iCOASST' (Nicholls et al, 2012). Wider pan-European studies have been completed, incorporating the region, such as RISC- KIT (van Dongeren et al, 2014).…”

Coastal zones attract human settlement, business and industry, and are instrumental to the functioning of societies both in coastal states and the wider global community. However, the oceans and coasts are under growing pressure as human practices change, populations rise and climate change impacts increase. In managing coastal regions, high quality data forms the basis of rational decision-making. Large volumes of 'triple bottom line' data exists representing a wide variety of environmental, social, and economic themes in coastal regions. Such data is especially crucial to development of environmental risk evaluations for the coast. The momentum driving the Open Source data movement across the world is accelerating and consequently, huge quantities of data are becoming freely available to the public. This presents a valuable opportunity for coastal managers, policy makers and land planners, who need to evaluate the full implications of their choices. Decision-makers frequently need to draw on many disparate datasets. However, this can be complicated by many factors, including a lack of awareness of the full range of datasets available. This paper seeks to explore this area, taking the UK as an example, to reveal how currently available open data sources relate to coastal management decision-making. Environmental risk management is a cross-cutting theme, relevant to all areas of coastal management. As such, this topic is discussed and addressed within a case study focusing on the vulnerable coastal region of East Anglia. In collation and analysis of coastal data Geographical Information Systems (GIS) can play an important role, in line with this GIS approaches were utilised within the case study. The case study led to development of a conceptual framework which can be applied to future coastal risk assessments, using Open Source data. The UK is currently at the forefront of the Open Source data movement and as such it is used as an example within this paper, however the issues addressed have international relevance, and the UK perspective is used to illustrate wider opportunities, resulting from freely available data sources, extending to management of coastal regions globally.

“…Predictive modelling at meso-scales is key to the successful anticipation and adaption to climate change at the coast (French and Burningham, 2009;Nicholls et al, 2012). The major challenge is that the timescales that matter for climate change take us out of our 'comfort zone' in terms of our ability to translate our understanding of coastal processes into models that retain a sound physical basis while at the same time demonstrating useful predictive skill.…”

Geomorphology is increasingly engaged with the connections between coastal behaviour and climate variability and change. While impacts of climate change at the coast are often primarily viewed in terms of landform adjustments to accelerated sea-level rise, geomorphologists are also starting to unlock the subtleties of how coastal processes are forced by a broader suite of climate factors. This progress report highlights three main strands of recent geomorphological research in this vein: the search for a broader suite of climatic signatures in recent coastal deposits; empirical analyses of the linkages between climate variables and contemporary shoreline change; and enhancement of our capability to predictively model climate-driven changes in coastal morphology.
