“…High frequencies of wetland herbs (mainly Cyperaceae) are recorded between around 3000 and 2000 cal yr BP (pollen Zone 2a). The absence of marine and brackish diatoms suggest the last phase of marine deposits was followed by a fluvial environment caused by sediment progradation and withdraw of shoreline around 1900 cal yr BP (Rolett et al, 2011).By comparison, extensive freshwater wetlands were emerging in northwest part of the Pearl River deltaic plain by 2500 years ago (Zong et al, 2013).…”

“…The major deltas and downstream river basins of southeast China originated during the late Pleistocene, followed by Holocene formation of expansive coastal lowlands and floodplains (Wang and Zheng, 1997;Zheng and Li, 2000;Zong et al, 2013;Innes et al, 2014). Among these are the lowlands and floodplain of the Fuzhou Basin (Lan et al, 1986;Zheng et al, 2005).…”

“…Neolithic cultures spread down the southeast coast of China and across the Taiwan Strait (Bellwood, 2005;Chi and Hung, 2010;Ruddiman et al, 2008). Data from the Pearl River delta shows that the shift to economic dependency on rice agriculture occurred 2500-2200 years ago (Zong et al, 2013). Similarly, for the Fuzhou Basin.…”

“…The population density of Chinese deltas increased significantly during the Tang Dynasty due to trade and employment opportunities, accelerating southward and eastward population migration (Zeng & Huang, 1987). Increasing populations placed stress on food production in the low-lying deltas; dikes were built to protect cultivation and guarantee agricultural production there, with paddy cultivation, sugarcane and fish ponds doubling as rice paddies (Zong et al, 2013).…”

Trends in flood risk management in deltas around the world: Are we going ‘soft’?

A. Wesselink et al. / Trends in flood risk management in deltasFlood-risk management (FRM) is shaped by context: a society's cultural background; physical possibilities and constraints; and the historical development of that society's economy, political system, education, etc. These provide different drivers for change, in interaction with more global developments. We compare historical and current FRM in six delta areas and their contexts: Rhine/Meuse/Scheldt (The Netherlands), Pearl River (China), Mekong (Vietnam), Ganges/ Brahmaputra/Meghna (Bangladesh) Zambezi/Limpopo (Mozambique), and Mississippi (USA). We show that in many countries the emphasis is shifting from 'hard' engineering, such as dikes, towards non-structural 'soft' measures, such as planning restrictions or early warning systems, while the 'hard' responses are softened in some by a 'building with nature' approach. However, this is by no means a universal development. One consistent feature of the application of 'hard' FRM technology to deltas is that it pushes them towards a technological 'lock-in' in which fewer and fewer 'soft' FRM alternatives are feasible due to increased flood risks. By contrast, 'soft' FRM is typically flexible, allowing a range of future options, including future hard elements if needed and appropriate. These experiences should lead to serious reflection on whether 'hard' FRM should be recommended when 'soft' FRM options are still open.

Catastrophic events often interrupt long‐term Earth surface processes. In coastal areas, although millennial‐scale trends of climatic and sea‐level changes determine the trajectory of sedimentary landform evolution, storm and/or tsunami activity can cause abrupt changes in depositional conditions that may alter the long‐term sedimentary processes. Here, we report a sedimentary hiatus that is widely observed from the late Holocene sedimentary sequence at the seabed along the southeast China coast. This hiatus was discovered by close temporal sedimentary and radiocarbon dating analyses of a seabed sedimentary sequence in the mouth area of the Pearl River estuary. The results suggest that a couple of metres in the middle to late Holocene sediment at the seabed were eroded by a catastrophic event happening c. 1000–800 cal. Years BP. In theory, a mega‐tsunami generated from the Manila Trench could have caused such erosion at the seabed, but there is a lack of direct geological and historical evidence to support such a hypothesis. Much more likely, a super‐typhoon struck the coast and caused the erosion. This hypothesis is strongly supported by the region's historical and geological records, which suggest a period characteristic of intense typhoons ranging from the Medieval Warm Period to the climate transition phase (c. 1000–600 cal. Years BP). During the subsequent Little Ice Age, deposition of sandy sediment continued, suggesting frequent but weaker typhoon activity. Over the past two centuries the deposition of sandy sediment and gravels began, implying the beginning of a phase of intensifying typhoon conditions, possibly a result of the recent warming climate. © 2020 John Wiley & Sons, Ltd.
