This is a numerical model for simualting river
and sea ice dynamics. See DYNAMICS OF RIVER ICE TRANSPORT AND ICE JAMS,
and SEA ICE DYNAMICS for more inforamtion.

| RICENİ - |
This is an updated version of the
one-dimensional river-ice simualtion model RICE. The model consists of two-major parts:
(1) An unsteady flow model for a channel network with ice; (2) a thermal and ice condition
simulation model. The model siumlates the water-temperature variation along the river,
including supercooling; frazil-ice concentration; anchor ice growth, decay, and release;
surface ice transport; ice-cover progression; undercover ice transport, deposition, and
erosion; thermal growth and decay of ice covers; and ice-cover stability.

| ROSSİ -
|
This is a series of models for simulating oil
slick transport in rivers and lakes (ROSS, ROSS2, and ROSS3). The model is a two-layer
two-dimensional model which simulates the mechanisms of advection, horizonatl
diffusion, mechanical spresding, shoreline deposition, evaporation, dissolution, vertical
mixing, resurfacing, and sinking.

| RSPILLİ - |
This is a two-dimensional Lagrangian computer
model for simulating chemical or oil transport in rivers. The model
considers the spilled chemical to be transported in the river as a mixed layer over the
depth of the flow and a bottom layer along the bed, with continuous exchange between the
two layers. The transport and fate processes include advection/diffusion,
sorption/desorption, settling, resuspension, diffusive exchange between sediment/water
interface, and can include volatization, photolysis, hydrolysis, and biodegradation.
