MOSART also provides an effective way of evaluating and diagnosing the soil hydrology simulated by land surface models through direct comparison of the simulated river flow with observations of natural streamflow at gauging stations Li et al. Moreover, MOSART provides a modeling framework for representing riverine transport and transformation of energy and biogeochemical fluxes under both natural and human-influenced conditions Li et al.

MOSART assumes that all the tributaries within a spatial unit can be treated as a single hypothetical sub-network channel with a transport capacity equivalent to all the tributaries combined. MOSART only routes positive runoff, although negative runoff can be generated occasionally by the land model e.

Negative runoff in any runoff component including , , is not routed through MOSART, but instead is mapped directly from the spatial unit where it is generated at any time step to the coupler.

If the channel slope is steep enough, the gravity force dominates over the others so one can approximate by the channel bed slope , which is the key assumption underpinning the kinematic wave method. If the water surface is sufficiently large or the water depth is sufficiently shallow, the hydraulic radius can be approximated by the water depth. This is the case for both hillslope and sub-network channel routing.

Here m and m are hydraulic radius for hillslope and sub-network channel routing respectively, and m and m are water depth during hillslope and sub-network channel routing respectively. It is assumed that surface runoff is generated uniformly across all the hillslopes. Currently, MOSART does not exchange water with the atmosphere or return water to the land model so its function is strictly to transport water from runoff generation through the hillslope, tributaries, and main channels to the basin outlets.

There are two levels of subcycling. The second level of subcycling is between the hillslope routing and channel routing. This is to account for the fact that the travel velocity of water across hillslopes is usually much slower than that in the channels.

The local time-stepping algorithm is to account for the fact that the travel velocity of water is much faster in some river channels e. That is, for each channel either a sub-network or main channel , the final time step of local channel routing is given as. The topographic parameters such as flow direction, channel length, topographic and channel slopes, etc. The channel geometry parameters, e.

The Manning roughness coefficients for overland and channel flow were calculated as functions of landcover and water depth. The full list of parameters included in this global hydrography dataset is provided in Table 2. Runoff treatment: In RTM runoff is routed regardless of its sign so negative streamflow can be simulated at times.

MOSART routes only non-negative runoff and always produces positive streamflow, which is important for future extensions to model riverine heat and biogeochemical fluxes. Outputs: RTM only produces streamflow simulation, whilst MOSART additionally simulates the time-varying channel velocities, channel water depth, and channel surface water variations.
