<br />STRKR - Starting value of loss coefficient on exponential reces- <br /> <br /> <br />sion curve for rain losses (snow-free ground). The <br /> <br /> <br />starting value is considered a function of infiltration <br />capacity and thus depends on such basin characteristics <br />as soil type, land use and vegetal cover. <br />RTIOL - Ratio of rain loss coefficient on exponential loss curve <br />to that corresponding to 10 inches more of accumulated <br />loss. This variable may be considered a function of the <br />ability of the surface of a basin to absorb precipitation <br />and should be reasonably constant for large rather <br />homogeneous areas. <br /> <br />ERAIN - Exponent of precipitation for rain loss function <br /> <br />ALOSS - (AK + DLTK) PRCpERA1N <br /> <br />that reflects the influence of precipitation rate on <br /> <br />basin-average loss characteristics. It reflects the <br /> <br />manner in which storms occur within an area and may be <br /> <br />considered a characteristic of a particular region. <br /> <br />Varies from 0.0 to 1.0. The terms in the equation are <br />defined as: <br /> <br />ALOSS - loss rate for particular time interval <br /> <br />11 <br />
