\cf2\fs28 B1.  SCS Model}{\cf2\fs24 \par }{\cf2 \par A. Description
\par \par The empirical approach to develop water infiltration 
equation consists of first finding a mathematical function whose shape 
as a function of time matches the observed features of the 
infiltration rate and then attempting a physical explanation of the 
process (Jury }{\cf2\i et al}{\cf2 ., 1991).   In semi-empirical 
models, most physical processes are represented by commonly accepted 
and simplistic conceptual methods rather than by equations derived 
from fundamentally physical principles.  The commonly used 
semi-empirical infiltration model in the fields of soil physics and 
hydrology is Soil Conservation Service (SCS) model.   A scenario was 
chosen to simulate water infiltration into a soil for conditions with 
rainfall and surface run off by using the SCS model.  Input parameters 
and simulation results are discussed below.  \par }}

point on the curves of Figs. B1-1 and B1-2 could represent one 
rainfall event. In figure B1-2,   the runoff does not occur in the 
event where the daily rainfall amount  is smaller than 1.64 inches (0.2F}{

the infiltration amount equals the rainfall amount.  After that,  }{
\cf2 the daily infiltration amount increases as the daily rainfall 
amount increases but the rate of the increase of  the daily 
infiltration decreases (Fig. B1-1).  Note that the SCS model  is 
applicable to the situation in which the }{\cf2\i daily}{\cf2  amounts 
of  rainfall, runoff and infiltration are of interest. }}
