“…Quy mô và mức độ ảnh hưởng của các yếu tố tự nhiên và các hoạt động của con người ở lưu vực sông Mê Kông và sông Hậu, cùng với các tác động còn chưa được nhận biết rõ ràng của quá trình biến đổi khí hậu toàn cầu [4][5][6] Nguyên nhân gây ra hiện tượng này có thể do khu vực chịu chi phối của chế độ dòng chảy thủy triều vào ra cửa sông Cung Hầu với tốc độ dòng chảy trung bình vào khoảng 0,4 -0,6 m/s, cùng với tác động trực tiếp của sông (cao trung bình từ 0,5 -0,7 m), đặc biệt là khi có gió mùa Đông Bắc [10]. Lực xung kích do sóng biển đã trực tiếp phá vỡ kết cấu bờ, bào mòn chân bờ, chuyển các dạng vật liệu kết cấu bờ và đáy (chủ yếu là bùn sét và cát mịn [11]) thành dạng lơ lửng sau đó chúng được vận chuyển đi xuống phía nam vùng Duyên hải bởi dòng chảy dọc bờ, dòng triều và hoàn lưu Biển Đông [10].…”

Multi-temporal Landsat data are used for this study over the period of 1989 to 2016 with imageries of 1989, 2001, 2009 and 2016. Band rationing method and threshold technique are applied for the coastline extraction. The Digital Shoreline Analysis System ENVI 5.1, eCognition and ArcGIS 10.3 are used to calculate shoreline rate-of-change statistics from multiple historical shoreline positions. The results show that shoreline change in the Hau river mouth area has a trend of deposition between 1989 and 2016 (27 years) with the accretion area ranging from 162.68 ha to 1,210.83 ha. Meanwhile, the erosion area only ranges from 0.002 ha to 183.53 ha. The results obtained from this study set a stage for new studies to understand the morphological changes of the river mouths in the Mekong Delta and coastal areas of Hau river.

“…A complicating factor is the rise in eustatic and relative sea level in the Mekong Delta that is the focus of the next section. The possibility of future shoreline erosion associated with a combined decline in sediment delivery and increase in the rate of sea level rise has resulted in several studies that suggest strategies such as (1) non-structural adaptation of coastal populations (Boateng, 2012), (2) creation of barriers using natural materials (Albers and Schmitt, 2015), and (3) increased planting of mangroves on sea-facing shorelines (Phan et al, 2015).…”

“…A successful adaptation strategy requires careful planning and simultaneous policy implementation (Boateng, 2012). This may be realized at the local level through zoning changes or revising building codes such as mandating raised buildings and bridges above predicted future flood-levels (Foster et al, 2011).…”

Vulnerability of coastal Connecticut to sea level rise: land inundation and impacts to residential property

Following an increase in large storm events, coastal communities have begun developing vulnerability assessments to prepare for future natural disasters and to provide a step towards the eventual development of resilience management plans. The goal of this study was to assess the vulnerability of coastal communities in the state of Connecticut to the impacts of sea level rise together with an analysis of the extent of inundated land and the economic impacts of such environmental phenomenon. Societal impacts as well as impacts on critical infrastructure were also investigated. The scope of the study focused on precision at the local level rather than regional generalizations. Impacts have been assessed at the municipality level, parcel by parcel. The shoreline of New Haven County, which was analyzed in this study, consists of seven municipalities located in the south central region of the state of Connecticut, in the U.S. The study analyzed impacts for 1 m and 2 m sea level rise scenarios. Land inundation was calculated as 15 km 2 and 25 km 2 for the two scenarios. The direct economic cost through residential property losses in the seven municipalities analyzed was estimated to be $1.3 billion and $2.2 billion due to land inundation and flooding, for 1 m and 2 m sea level rise scenarios, respectively. The estimated economic impacts to residential property is significant when 2 considering that only seven municipalities stretching 94 km of coastline were analyzed in the study. The overall weighted average was $15 million/km coastline and $24 million/km coastline for 1 m and 2 m sea level rise, respectively. These values do not take into account increased flood risk during storm events, which are expected to increase in frequency and severity, and therefore may be considered to be conservative. Effects of sea level rise would be felt at the local level, which is unique for every location, and so should be the potential solutions. A variety of strategies have been identified that could be applied to the municipalities analyzed, including implementing green infrastructure in the form of restoring wetlands and creating living shorelines, adjusting building codes and zoning ordinances, and reinforcing existing infrastructure.
