What's the difference between confluence and merging?
Confluence
Definition:
(n.) The act of flowing together; the meeting or junction of two or more streams; the place of meeting.
(n.) Any running together of separate streams or currents; the act of meeting and crowding in a place; hence, a crowd; a concourse; an assemblage.
Example Sentences:

(15) The total number of lesions varied, though not greatly, over the whole follow-up, but there was an influence of the clinical course of MS on the pattern of lesions in MR imaging, mostly in respect to the number of confluences and the size of the lesions.
(16) 3) The pressures of the inferior vena cava at the confluence of right and left common iliac veins with 20 and 40mmHg showed no significant difference immediately after the pressurization, but thereafter showed a increasing tendency in the group with 40mmHg (p less than 0.05).

(19) After the preselection of patients based on knowledge of the anatomical patterns, a systemic-pulmonary artery shunt may be performed without cardiac catheterization if these rules for definitive patient selection are followed: (1) accurate clinical assessment to identify the patients with restricted pulmonary blood flow; (2) precise intracardiac diagnosis by 2-D and Doppler echocardiography; and (3) definitive 2-D echocardiographic visualization of the pulmonary venous connection and the confluence of the pulmonary arteries.
(20) Novel transformed variants generally arise after prolonged confluence and cessation of net growth, with these new types of foci appearing during a second round of confluence, although not in the first round.
Merging
Definition:
(p. pr. & vb. n.) of Merge
Example Sentences:
(1) Still higher intensities caused the 2 phases of inhibition to merge, giving the appearance of a single, prolonged, inhibitory response.
(2) White lines 2 and 5 tended to merge with lines 1 and 4, respectively, in collagen fibrils formed from a solution containing a significant amount of type I collagen or pure type I collagen.
(3) As alcohol concentration is increased the lower L beta I to P beta' and main P beta' to L alpha transitions of DHPC merge at the threshold concentration of the biphasic effect, so that above this concentration there is one phase transition from L beta I directly to L alpha.
(4) In addition, if a preceding procedural step is a subset of the next one, merging between the two steps occurs.
(5) The subicular area, best expressed in the temporal sector, extends anteriorly over the corpus callosum to the subcallosal gyrus and, throughout its extent from the uncal to the septal junction, is clearly demarcated from limbic neocortex by a transition zone characterized by archicortical cells merging with cells in the deep layer of the bordering neocortex.
