Delta Evolution is the label we use since 2005, for the Utrecht University research line in Lowland Geomorphology and Quaternary Geology, carried out by the Department of Physical Geography, in cooperation with other institutes. Delta Evolution is also the label put on the strategic research cooperation (since 2008) of the group with departments in Deltares Research Institute and TNO Geological Survey of the Netherlands, that have their offices on the Utrecht science campus too. The Delta Evolution program also connects to the network of alumni of Physical Geographers and Quaternary Geologists active in commercial consultancy companies and governmental agencies in the field of water management, hydrology, civil engineering, nature conservation and archaeology in The Netherlands and to colleagues at other universities - with whom we collaborate in shared projects. Our research and networks extend to deltas internationally - see the pages of the Future Deltas focus area for example. 

The Netherlands and the Rhine-Meuse delta in it are strongholds for our research. Our scientific research treats this delta as the mega-case, to draw smaller cases from - and to compare with other delta systems (other mega-cases) to test and validate what part of our insights are delta-specific and what is generic. The lowlands that the program focuses on include: delta plains, coastal plains, larger river valleys, peat wetlands, lagoon and fenlands and so on. These areas connect to upstream catchments and coastal marine systems downstream. Besides holding sedimentary and geomorphic record of their dynamic formation (lowland genesis, natural and human impacts thereon), the lowlands are also archives that recorded change of the upstream catchment (size of floods and amounts of sediment received), the coastal system (transgression, tides, barrier coasts, storms), the climate system (storms, precipitation, temperature), the biological system (vegetation and fauna, aquatic, riparian, terrestrial), the deeper earth (neoteconics, glaciohydro-isostasy), and archeological history (finds, sites, use of landscape). This feeds interdisciplinary and multidisciplinary research. Also, the better the build-up, making-of and age of the lowlands is understood (data integration, synthesis), the better the archives and science based on becomes (duplication, cross-validation, stacking). This is a main reason to carry-over mapping and dating knowledge from individual projects to Delta Evolution's living datasets, that in turn feed into new projects.

Delta Evolution as an umbrella programma, bundles series of PhD/Postdoc projects and contract-research projects and includes long-term dataset management from and between these projects. Goals in Delta Evolution at present are:

1. Perform novel scientific research in Geomorphology and Quaternary Geology of lowland areas,

• by using and expanding the present datasets (already huge and of high quality) and knowledge (from several disciplines), 
• by exploring the limits of our process-understanding and innovate the techniques of modelling geomorphology to cover longer timescales (1000-100,000 years), 
• by pushing the resolution and accuracy of our mapping and dating, and innovate the techniques that combine these (GIS palaeogeography, 3D/4D geomodelling),
• by striving to time-slice the evolution of deltas and quantify rates of morphological, sedimentary and hydrological change as they were changing over time (thus documenting shifts in controls)
• by addressing research questions on the delta system at nested spatial, temporal and functional scales (whole delta, individual branches and swamps, fluvial vs. tidal affected reaches, human-impacted, semi-natural, natural parts of the system's suites of environments and processes; transgressive vs high-stand periods).
• by combining new-collected data from field- and lab work with existing data, statistical analysis and physical numerical modelling.

2.  Synchronize the academic delta research with applied research activities

• by valorizing new scientific insights early on in national mapping projects and geological/geotechnical/geohydrological advice.
• by making early use of data-collection opportunities arising from larger infrastructural projects in the Netherlands delta, in academic research.
• by topping up scientific research with contract-research and vice-versa: have exchange of input data, syncing the interpretation, and reviewing the data output.
• by releasing high-quality data-sets and update these from time to time: take-in, monitoring and review of applied and academic research results from 3rd parties.
• by taking up advisory roles, if possible in early stages, in projects that demand geological-geomorphological  information for plannig and decision making.
• by connecting the Delta Evolution research output to internationally actual themes such as: global change, sustainability, climate change, sea-level change and land subsidence, delta urbanisation, environmental pressure, groundwater demand, hydrocarbon demand, ecological demand, interdisciplinarity science demand.
