# latq\_co

Soil lateral flow is computed for each soil layer using a hillslope storage method. The equation is a function of excess water above field capacity, total soil water capacity, hydraulic conductivity, slope, and flow length. The lateral flow coefficient is a direct linear coefficient applied to the hillslope storage equation.
