An understanding of the spatial and temporal changes of estuarine islands is needed for environmental change monitoring and assessment in estuarine and coastal areas. Such information can also help us better understand how estuarine islands respond to sea level rise in the context of global warming. The temporal changes of two estuarine islands in Shanghai near the Yangtze River Estuary were obtained using Landsat TM (Thematic Mapper) and ETM+ (Enhanced Thematic Mapper) images from 1987 to 2016 on an annual scale. First, a composite image was generated by using the multi-temporal Landsat images for each year. Then, a modified normalized difference water index (MNDWI) was applied to the annual estuarine island maps using a threshold segmentation method. -

A Comparative Study of the Flux and Fate of the Mississippi and Yangtze River Sediments
312 Sediment Dynamics from the Summit to the Sea (Proceedings of a symposium held in New Orleans, Louisiana, USA, 11–14 December 2014) (IAHS Publ. 367, 2014). A comparative study of the flux and fate of the Mississippi and Yangtze river sediments KEHUI XU1,2 & S.L. YANG3 1 Department of Oceanography and Coastal Sciences, Louisiana State University, Baton Rouge, Louisiana 70803, USA [email protected] 2 Coastal Studies Institute, Louisiana State University, Baton Rouge, Louisiana 70803, USA 3 State Key Lab of Estuarine and Coastal Research, East China Normal University, Shanghai 200062 China, Abstract Large rivers play a key role in delivering water and sediment into the global oceans. Large-river deltas and associated coastlines are important interfaces for material fluxes that have a global impact on marine processes. In this study, we compare water and sediment discharge from Mississippi and Yangtze rivers by assessing: (1) temporal variation under varying climatic and anthropogenic impacts, (2) delta response of the declining sediment discharge, and (3) deltaic lobe switching and Holocene sediment dispersal patterns on the adjacent continental shelves. Dam constructions have decreased both rivers’ sediment discharge significantly, leading to shoreline retreat along the coast. The sediment dispersal of the river-dominated Mississippi Delta is localized but for the tide-dominated Yangtze Delta is more diffuse and influenced by longshore currents. Sediment declines and relative sea level rises have led to coastal erosion, endangering the coasts of both rivers. Key words Mississippi River; Yangtze River; water discharge; sediment transport; dam construction INTRODUCTION Large rivers play a key role in delivering water and sediment to oceans (Milliman & Meade, 1983; Milliman & Syvitski, 1992; Milliman & Farnsworth, 2011). -

Shanghai Shoreline Evolution Interpreted from Historical Atlas and Remote Sensing Imagery Over the Past 2,200 Years
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Volume XLI-B8, 2016 XXIII ISPRS Congress, 12–19 July 2016, Prague, Czech Republic SHANGHAI SHORELINE EVOLUTION INTERPRETED FROM HISTORICAL ATLAS AND REMOTE SENSING IMAGERY OVER THE PAST 2,200 YEARS H. Mi a,b, W. Wang a,b, G. Qiao a,b, * a College of Surveying and Geo-Informatics, Tongji University, 1239 Siping Road, Shanghai, China b Center for Spatial Information Science and Sustainable Development, Tongji University, 1239 Siping Road, Shanghai, China Commission VIII, WG VIII/9 KEY WORDS: Shanghai, Shoreline Change, Evolution, Atlas, Remote Sensing ABSTRACT: Shanghai, the axis of economic development in China and holding the most prosperous metropolis in the world, is located at Yangtze Estuary which is susceptible to shoreline changes affected by different factors, such as sediment supply and sea level changes, making it very important to study the shoreline changes over long time period. This paper presents the Shanghai shoreline evolution process from BC 221 up to 2015, by employing both the cartographic data (historical atlas) and the remote sensing images. A series of image processing techniques were applied to seamlessly register the historical atlas and satellite images to the same orthophoto base map, followed by the semi-automatic extraction of shoreline from images. Results show that since BC 221, the Shanghai shoreline has been witnessing distinct progradation, and the rate of shoreline advance varied in different areas. The average shoreline change in southern Yangtze Estuary was about 2,573 km2 (accretion) between BC 221 and 1948 with a 40 km progradation, while the shoreline in northern Hangzhou Bay kept relatively steady after 1671. -

The major depocenter is validated at the delta front sedimentary facies above the normal wave base (NWB), where accumulation exceeds erosion. This alternated sedimentation does not accommodate Pb-210 and Cs-137 measurement, although sedimentation rates of less than 0.2e5.0 cm yrÀ1 were recorded in the fine-grained (silty) sediments, which were interbedded with coarse- grained (sandy) sediments. However, historical DEM data provide more detailed information on sedimentation in the delta front facies, where accumulation is dominant in the sandy shoals (1.73e8.30 cm yrÀ1) and delta front slope (5.22 cm yrÀ1) facies. -

Beach & Bank Protection Works and Water & Soil Resources
12th ISCO Conference Beijing 2002 Beach & Bank Protection Works and Water & Soil Resources Sustainable Development In the Yangtze River Estuary Ji Yongxing1, Liu Shuiqin2 and Mo Aoquan1 1Shanghai Water Conservancy Engineering Design & Research Institute Zhongning Rd. 99, Shanghai, 200063, P.R.C. E-mail: [email protected] 2Resource and Environment College, East China Normal University North Zhongshan Rd. 3663, Shanghai, 200062, P.R.C. Abstract: The paper analyses water & sand transportation and tidal flat scour-and-fill development tendency. According to scour-and-fill stability, the paper presents several protection methods for different failure factor at different eroding shore to prevent water and soil loss and control the estuary development trend; and accretion promotion and reclamation at properly occasion to keep the water & soil resources sustainable development. At last, the paper suggests that water & soil resources and sustainable development at he Yangtze River Estuary must be sufficiently considered in accretion promotion and reclamation by analysis of the positive and impassive effects on resources, environment and ecological environment. Keywords: the Yangtze River Estuary, beach & bank protection, water & soil resources, sustainable development 1 Introduction The sand from upstream deposited at the estuary and the beach is the material base of bottomland of our country. The Yangtze River Estuary has plenty of sand sources. (Fig.1) There are 4.68 108t sands every year transported by water from upstream to the Estuary, 50per deposit and silt at the Yangtze River Estuary, which is extensive and abundant beach resource [1]. It is important for Shanghai and Jiangsu’s economic development and people’s life quality. -
Religious Radicalism After the Arab Uprisings JON B
Religious Religious Radicalism after the Arab Uprisings JON B. ALTERMAN, EDITOR Radicalism The Arab uprisings of 2011 created unexpected opportunities for religious radicals. Although many inside and outside the region initially saw the uprisings as liberal triumphs, illiberal forces have benefitted after the Arab disproportionately. In Tunisia, formally marginalized jihadi-salafi groups appealed for mainstream support, and in Egypt, the Muslim Brotherhood triumphed in Jon B. Alterman Uprisings elections. Even in Saudi Arabia, not known for either lively politics or for Jon B. Alterman political entrepreneurship, a surprising array of forces praised the rise of “Islamic democracy” under a Muslim Brotherhood banner. Yet, at the same time, the Arab uprisings reinforced regional governments’ advantages. The chaos engulfing parts of the region convinced some citizens that they were better off with the governments they had, and many governments successfully employed old and new tools of repression to reinforce the status quo. Religious Radicalism after the Arab Uprisings In the Middle East, conflicts that many thought were coming to an end Religious Radicalism after the Arab Uprisings will continue, as will the dynamism and innovation that have emerged among radical and opposition groups. To face the current threats, governments will need to use many of their existing tools skillfully, but they will also need to judge what tools will no longer work, and what new tools they have at their disposal. The stakes could not be higher. 1616 Rhode Island Avenue NW Washington, DC 20036 t. 202.887.0200 | f. 202.775.3199 www.csis.org EDITOR Jon B.

The ethnographic material is collected from informants\agents of an, initially, heterogeneous cultural background and with a highly individualistic discourse, who, paradoxically, form a group. The identity of this new Mykonian group of exogenous locals7 is self-created and draws on several local7 myths. Therefore, the ethnography concentrates on the discursive making of these myths. -
