Model description
Model type: | Modular model for the coastal domain. |
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. |

Process description
Processes represented by model: | longterm 2D deltaic sedimentation and clinoform formation for fluvial dominated deltas |
Key physical parameters & equations: | see references |
Length scale & resolution constraints: | Model is intended to generate stratigraphy for 2D profiles of large deltas (100's of km's) |
Time scale & resolution constraints: | Mostly tested for Holocene applications (>10,000yrs), potentially longer time scales. |
Numerical limitations and issues : | -- |
Testing
Available calibration data sets: | Theoretical tests, Volga case study, Kura case study, (see references) |
Available test data sets: | Caspian sea experiences extremely rapid sea level fluctuation, making it a great test data set for coastline shifts. |
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. |
