|CSDMS meeting abstract=Delta environments, on which over half a billion people live worldwide, are sustained by sediment delivery. Factors such as subsidence and sea level rise cause deltas to sink relative to sea level if adequate sediment is not delivered to and retained on their surfaces, resulting in flooding, land degradation and loss, which endangers anthropogenic activities and populations. The future of fluvial sediment fluxes, a key mechanism for sediment delivery to deltas, is uncertain due to complex environmental changes which are predicted to occur during the coming decades. Fluvial sediment fluxes under environmental changes were investigated to assess the global sustainability of delta environments under potential future scenarios up to 2100. Climate change, reservoir construction, and population and GDP (as proxies for other anthropogenic influences) change datasets were used to drive the catchment numerical model WBMsed, which was used to investigate the effects of these environmental changes on fluvial sediment delivery. This method produced fluvial sediment fluxes under 12 scenarios of climate and socioeconomic change which are used to assess the future sustainability of 47 deltas, although the approach can be applied to deltas, rivers, and coastal systems worldwide. The results suggest that fluvial sediment delivery to most deltas will decrease throughout the 21st century, primarily due to anthropogenic activities. These deltas will likely become unsustainable environments, if they are not already, unless catchment management plans are drastically altered.

HPCCprojects:Understanding sediment delivery to deltas under environmental changes using WBMsed and HydroTrend

Fdunn: Created page with "<!-- How to create a new "HPCCproject" page: 1) Log in to the wiki 2) Create a new page for each HPCCproject, by using the following URL: * http://csdms.colorado.edu/wiki/H..."

__NOTOC__
={{PAGENAME}}=
==Project description==
This project is focused on increasing understanding of how environmental changes affect sediment flux to the world's more vulnerable deltas. Relative sea-level change is affected by sediment deposition (aggradation) along with subsidence, isostatic, and eustatic changes. This means that the sustainability of delta environments relies in part on the rates of aggradation which in turn are affected by sediment delivery from catchments feeding deltas.

==Objectives==
Establish future environmental changes which will affect sediment delivery to deltas and the potential ranges of said changes.

Calibrate existing sediment flux models, such as HydroTrend or WBMsed, for a selection of major vulnerable deltas using historical reference periods.

Project current and future sediment delivery to deltas to investigate delta sustainability and the relative effects of pressures on sediment delivery.

==Time-line==
2013-2016

==Models in use==
Currently using [http://csdms.colorado.edu/wiki/Model:HydroTrend HydroTrend], also looking to investigate [http://csdms.colorado.edu/wiki/Model:WBMsed WBMsed] for use in the project.

==Results==
The results of this research will be able to inform the identification of a range of factors affecting delta elevation change relative to sea level. Further research will focus on using these data to refine definitions of delta vulnerability and identifying proxies for environmental changes which affect delta aggradation, such as land use change and channel engineering.
