D
Precipitation enters the snowpack, if present, and is then available as snowmelt, depending mainly on air temperature and solar radiation. Snowmelt and rainfall partly infiltrate infiltrate into the soil and partly run off directly to surface storage, depending upon the moisture content of the soil. Infiltration is high if the soil is dry, and surface runoff is high if the soil is saturated. Soil moisture evaporates or is transpired by vegetation, depending on the types of vegetation, the season, solar radiation, air temperature, humidity, and wind speed. The remainder percolates into deeper basin storages that feed surface storage through interflows and groundwater flows. Generally, these supplies are high if the soil and groundwater storages are large. Finally, there is a flow into surface storage from the upstream cell, which is routed, along with all the other flows into surface storage, through the cell into the next downstream cell. +

Precipitation is generated by a climate routine within the model. Snow accumulation and melt,glacier growth and ablation, surface runoff, and groundwater evaporation, retention and recharge.
Long and short term sediment discharge is solved by an empirical relation. +
T

F
Process:
# carbonate productivity and deposition
# winnowing
# reef development
# carbonate depositional facies
Model determines these through five deterministic and fuzzy steps:
# data input
# data fuzzification
# fuzzy rule analysis
# aggregation of results
# defuzzification +
P
Processes like:
*Saturated subsurface flow.
*Variably-saturated subsurface flow.
*Integrated overland flow.
*Land-energy budget.
*Shallow heat transport.
*Bio-geochemistry (plant/water interactions).
*Correlated, Gaussian random field generators. +

Processes:
*Rainfall: gage with nearest neighbor or inverse distance-squared weighting, radar.
*Interception: empirical model.
*Infiltration: Green & Ampt, Green & Ampt with redistribution, three-layer Green & Ampt, or Richard's equation.
*Overland runoff: 2-D finite volume diffusive wave with overland flow dykes and pothole lakes.
*Channel routing: 1-D dendritic finite-volume diffusive wave with culverts, on-channel lakes, rule curves, rating curves, scheduled releases.
*Groundwater: 2-D finite-difference with wells and various boundary conditions.
*Overland erosion: three alternative source equations, raindrop impact, erosion limits, deposition, arbitrary size classes.
*Channel sediment transport: advection-diffusion for fines, stream power for sands.
*Fate and transport of conservative and non-conservative
