RRAWFLOW is a lumped-parameter model that simulates streamflow, 
springflow, groundwater level, solute transport, or cave drip for a 
measurement point in response to a system input of precipitation, 
recharge, or solute injection. For many applications, a simple lumped 
model, such as RRAWFLOW, simulates the system response with equal 
accuracy to that of a complex distributed model. The ease of model 
construction and calibration makes RRAWFLOW a good choice for many 
applications, and it provides professional hydrologists and students 
with an accessible and versatile tool.

RRAWFLOW includes a time-series process to estimate recharge from 
precipitation and simulates the response to recharge by convolution; 
that is, the unit-hydrograph approach. Gamma functions are used for 
estimation of the impulse-response function (IRF), also known as the 
unit hydrograph, and nonparametric options are available also. Several 
options are available to simulate time-variant systems. 

he RRAWFLOW program (v1.16) is written in R language. It is not 
necessary to know the R language to execute the model, but R must be 
installed on the user’s computer.
