B
BIT Model takes into consideration five different processes:
* reworking of the beach profile. The model assumes that the wave action reworks the beach profile towards an equilibrium configuration described by the Dean's equation;
* inner-shelf sediment redistribution, which is the redistribution of sediments beyond the beach toe determined by the bottom shear stresses produced by wind waves;
* overwas, which is the erosion of sediment along the beach profile and its corresponding deposition on the top of the barrier island or in the back-barrier area. Overwash is related to storm surges produced bt extreme atmospheric events;
* lagoonal deposition, which is the deposition of fine sediments in the accomodation space between the barrier island and the mainland;
* aeolian sediment reworking, which represents the wind action on the subaerial part of the island. +
C
Basic processes include runoff generation, water erosion and sediment transport, and gravitational erosion and sediment transport. Depending on the application, the user can apply a vegetation-growth module, various tectonic functions, and other options. +
B
Basin and Landscape Dynamics (Badlands) is a parallel TIN-based landscape evolution model, built to simulate topography development at various space and time scales. The model is presently capable of simulating hillslope processes (linear diffusion), fluvial incision ('modified' SPL: erosion/transport/deposition), spatially and temporally varying geodynamic (horizontal + vertical displacements) and climatic forces which can be used to simulate changes in base level, as well as effects of climate changes or sea-level fluctuations. +
C
Bay, marsh, and forest evolution on a coastline. Simulates marsh edge erosion, bay depth changes with wind waves, and marsh migration into coastal forests, and the carbon processes associated with these changes. +
Bay, marsh, and forest evolution on a coastline. Simulates marsh edge erosion, bay depth changes with wind waves, and marsh migration into coastal forests, and the carbon processes associated with these changes. Restorations, when turned on, modify erosion and accretion processes and subsequent carbon storage/decomposition. +

Erosion, transport and deposition of cohesive sediment. +
R
Bed-material sediment transport and storage on a river network. +

Bedrock fluvial incision (shear stress or sediment flux dependency).
Mass wasting (creep and threshold-limited).
Bedload sediment transport & deposition in streams, fans, deltas.
Impact cratering, aeolian deposition, lava flows.
Flow routing with evaporation from depressions. +

O
Bottom orbital velocity is calculated from surface wave conditions using linear wave theory. A spectral approach is used. If input wave data are just wave height and period, a spectrum is estimated based on those as described in Wiberg and Sherwood 2008. Several spectral representations are available, and spectra can be estimated based on wind speed if surface wave conditions are unknown. +
C
CAM treats radiative transfer, tidal forcing from Saturn, a planetary boundary layer and surface interaction, thermal conduction in the soil and chemistry. The CARMA part of the code does the aerosol microphysics involving emission, coagulation and sedimentation. +
F
Calculate water depth from a flood extent polygon (e.g. from remote sensing analysis) based on an underlying DEM.
Program procedure:
1. Flood extent polygon to polyline
2. Polyline to Raster - DEM extent and resolution (Env)
3. Con - DEM values to Raster
4. Focal Statistics loop
5. Water depth calculation - difference between Focal Statistics output and DEM +
S
Centerline migration, Floodplain sediment, and channel profile evolution, depending upon choices in the parameter input files, as detailed in the model documentation. +

B

W
Climate generation (CLIGEN), infiltration, percolation, evapotranspiration, plant growth, residue management and decomposition, runoff, hydralics of overland flow, soil detachment by raindrop impact and shallow flow (interrill), soil detachment by excess flow shear stress (rill, channel), sediment transport, sediment deposition, irrigation, winter processes (snow melt, frost, thaw), channel erosion processes, sedimentation in impoundments. +
