Reviews and syntheses: Dams, water quality and tropical reservoir stratification
Abstract. The impact of large dams is a popular topic in environmental science, but the importance of altered water quality as a driver of ecological impacts is often missing from such discussions.Expand
Sinking deltas: trapped in a dual lock-in of technology and institutions
ABSTRACT In delta areas, flood protection structures and large-scale land reclamation are preferential water management strategies to cultivate soft delta soils. Over the past decades, riverExpand
Geometric modeling of Holocene large-river delta growth patterns, as constrained by environmental settings
Topographic/bathymetric conditions of the continental shelf can significantly influence the long-term growth of river deltas. In particular, these conditions constrain the accommodation space forExpand
Salinization in large river deltas: Drivers, impacts and socio-hydrological feedbacks
Salinization of freshwater and soils is a global phenomenon that adversely affects 500 million people, particularly in low-lying river deltas. Impacts of salinity on food and water security andExpand

An analytical framework for strategic delta planning: negotiating consent for long-term sustainable delta development
Sectoral planning on water, agriculture and urban development has not been able to prevent increased flood risks and environmental degradation in many deltas. Governments conceive strategic deltaExpand
Propensity for erosion and deposition in a deltaic wetland complex: Implications for river management and coastal restoration
Abstract The Mississippi River Delta is one of the most rapidly changing area on Earth, with large areas experiencing land loss and smaller areas experiencing loss. While some of the drivers of theseExpand
Undervalued Impacts of Sea-Level Rise: Vanishing Deltas
Simplifying a deltaic labyrinth: anthropogenic imprint on river deltas
The information contained by historical maps provides a good source of understanding the complex transformation of a deltaic environment by human activity. Using the Danube delta as an example, hereExpand
A Graph-Theoretic Monte Carlo Framework for Comparing Delta Surface Dynamics and Subsurface Structure in Numerical Models and Physical Experiments
As climate changes and populations grow, a deeper understanding of deltaic surface and subsurface processes will help design sustainable management practices of delta resources. Numerical deltaExpand


Sustainable sediment management in reservoirs and regulated rivers: Experiences from five continents
By trapping sediment in reservoirs, dams interrupt the continuity of sediment transport through rivers, resulting in loss of reservoir storage and reduced usable life, and depriving downstreamExpand
The response of deltas to sea-level rise: Natural mechanisms and management options to adapt to high-end scenarios
Abstract The response of deltas to sea level rise (SLR) has mostly been studied from a perspective of human impacts like global warming and impoundment, or from a perspective of natural changesExpand
Maintenance of large deltas through channelization: Nature vs. humans in the Danube delta
A B S T R A C T Over the last half century, while the total sediment load of the Danube dramatically decreased due to dam construction on tributaries and its main stem, a grand experiment wasExpand
Tidal wetland stability in the face of human impacts and sea-level rise
Whether wetlands continue to survive sea-level rise depends largely on how human impacts interact with rapid sea- level rise, and socio-economic factors that influence transgression into adjacent uplands. Expand
Natural processes in delta restoration: application to the Mississippi Delta.
Understanding the mechanisms by which deltaic channel networks self-organize, grow, and distribute sediment and nutrients over the delta surface and coupling these to ecosystem processes, especially the interplay of topography, network geometry, and ecosystem dynamics, is understood. Expand
Drowning of the Mississippi Delta due to insufficient sediment supply and global sea-level rise
Global sea-level rise, reduced sediment supply and subsidence threaten the stability of the Mississippi Delta. Calculations of riverine sediment load and storage indicate that 10,000–13,500 km2 ofExpand
Sinking deltas due to human activities
Many of the world's deltas are densely populated and intensively farmed. An assessment of recent publications indicates that the majority of these deltas have been subject to intense flooding overExpand
Morphodynamics of deltas under the influence of humans
Abstract A consistent database was established to characterize key environmental factors known to control delta morphology. The database includes the location, basin morphology, fluvial and sedimentExpand
Restoration of the Mississippi Delta: Lessons from Hurricanes Katrina and Rita
Science must guide MDP restoration, which will provide insights into delta restoration elsewhere and generally into coasts facing climate change in times of resource scarcity. Expand
