DeltaSIM

Also known as
Model type	Single
Model part of larger framework
Note on status model
Date note status model

Incorporated models or components:

Spatial dimensions
Spatial extent
Model domain	Coastal
One-line model description	Process-response model simulating the evolution and stratigraphy of fluvial dominated deltaic systems
Extended model description	A process-response model simulating the evolution and stratigraphy of fluvial dominated deltaic systems in two dimensions, based on simple approximations of erosion and deposition. The model is called DELTASIM, and was initially presented by Overeem et al. (2003) as AQUATELLUS. DELTASIM has several improvements, the main algorithm has been revised and the output can be presented as probabilistic output.

Keywords:	delta evolution, stratigraphy, fluvial,

Describe processes represented by the model	longterm 2D deltaic sedimentation and clinoform formation for fluvial dominated deltas
Describe key physical parameters and equations	see references
Describe length scale and resolution constraints	Model is intended to generate stratigraphy for 2D profiles of large deltas (100's of km's)
Describe time scale and resolution constraints	Mostly tested for Holocene applications (>10,000yrs), potentially longer time scales.
Describe any numerical limitations and issues	--

Describe available calibration data sets	Theoretical tests, Volga case study, Kura case study, (see references)
Upload calibration data sets if available:
Describe available test data sets	Caspian sea experiences extremely rapid sea level fluctuation, making it a great test data set for coastline shifts.
Upload test data sets if available:
Describe ideal data for testing	Known boundary conditions, discharge, and sediment load as well as basin fluctuations. Dated stratigraphic profiles in deltas that are mostly fluvial dominated, ie lake deltas.
