CHARIMA is a general-purpose computer code for the simulation of steady or unsteady water, sediment, and contaminant movement in simple or complex systems of channels. Water movement (hydrodynamics) forms the core of a CHARIMA simulation; mobile-bed (sediment) and contaminant dynamics can be activated or deactivated. Mobile-bed capabilities include bedload and/or suspended-load transport of mixtures of noncohesive or cohesive sediment, along with the associated short- or long-term bed-level changes (aggradation and degradation), bed-sediment sorting, and armoring. Subsurface layering, pre-existing or as the result of persistent deposition, is included. Contaminant capabilities include transport and fate of any number of conservative contaminants, and heat. Transport of radionuclides and their selective sorption interaction with sediment size classes, including subsurface sediments, has recently been developed. Ni
