Estuarine geomorphology worldwide has greatly changed in the Anthropocene due to intensive human inferences in river basin and within estuary, which has received increasing global concerns. Here, recent morphodynamic evolution of Jiuduan Shoal (JDS), the largest uninhabited island in the Yangtze (Changjiang) Estuary, and associated controlling factors were analyzed based on unique high-resoluti...

Tidal flats play a critical role in supporting biodiversity and in providing ecosystem services but are rapidly disappearing because of human activities. The Yangtze Estuary is one of the world's largest alluvial estuaries and is adjacent to the most developed economic zone in China. Using the Yangtze Estuary as a study region, we developed an automatic algorithm to estimate tidal flat areas ba...

Abstract A geoarchaeological coring survey of the Forum Boarium has shed considerable light on Rome's archaic landscape. We present first empirical evidence that substantiates ancient and modern assumptions about existence a river harbour ford in early Rome. Prior to growth city, riverbank — reconstructed as high ledge at base Capitoline Hill low-lying shore north Aventine was particularly adva...

This paper reviews two important sources of innovation linked to the maritime environment and more importantly ports: potential coupling sediment management (bio)remediation. The detrimental effects dredging are briefly considered, but focus here is on a sustainable alternative method managing problem siltation. technique consists fluidizing in situ, lowering shear strength maintain navigable u...

A fish survey in 35 stream reaches (from 1st to 3rd order) with physicochemical and habitat assessment in the São José dos Dourados system, southeastern Brazil, was conducted. Most of the basin land cover (77.4%) is used for pasture. From the sampled stream reaches, 24 were of good physicochemical quality, 10 of fair quality, and only one of poor quality. A habitat assessment showed that 10 str...

Low and relatively constant temperatures, seasonal pulses of primary production, changes in ice cover, siltation and salinity are the main characteristics of polar marine ecosystems. Shallow coastal systems are especially affected by ice as a disruptive factor, which has a huge effect in structuring the established benthic communities, both in the Antarctic (Dayton 1990, Clarke 1996a, Grebmeier...

Wetlands provide a diverse range of ecosystem services supporting livelihoods of many people. Despite their value, wetlands are continuously being degraded. There is scant information on individual wetlands, people’s dependency and their exploitation at a local scale. We therefore assessed wetland ecosystem services, the drivers of change and impacts of those drivers on ecosystem services and p...

Even though soil loss in the lowlands imposes not as much a restriction on land use and agricultural productivity as in erosion affected mountainous areas, the input of fine sediment into the rivers and streams is a concern due to water quality issues and substrate siltation. Drains, river banks and agricultural fields are the three main sources of fine sediment in lowland regions. For a succes...
