<br />#AIl time-dependent factors change according to seasonal and, in some cases,
<br />even diurnal cycles
<br />
<br />*lncluded among time-dependent factors because not all gaps contain water
<br />all of the time; thus, the soil strength in the bottom of a dry gap is
<br />time-dependent~
<br />
<br />**These two factors are not applicable in the case of dry gaps.
