French term or phrase:abaque de calcul
Has anyone heard this term before and know its specific equivalent? I believe that the abaque is a curve or a graph. Thanks!
En absence de données topographiques des fils d’eau une modélisation des réseaux ne peut être réalisée (on suppose néanmoins que les profils en long des principaux collecteurs seront mis à disposition). La capacité des principaux collecteurs sera définie par l’utilisation d’**abaque de calcul** en appliquant une pente définie en concertation avec le maître d’ouvrage. Les capacités de réseaux seront comparées au débit de pointe enregistré sur les principaux PR. Il en sera ainsi déduit le taux de saturation des principaux collecteurs.
Explanation: nomograph and/or nomogram, aka abac in English!

NOM•O•GRAPH (nŏm\'ə-grăf\', nō\'mə-) or NOM•O•GRAM (-grăm\')
n.
1. A graph consisting of three coplanar curves, each graduated for a different variable so that a straight line cutting all three curves intersects the related values of each variable.
2. A chart representing numerical relationships.
NOM•O•GRAPH (nŏm\'ə-grăf\', nō\'mə-) or NOM•O•GRAM (-grăm\')

A graph consisting of three coplanar curves, each curve graduated for a different variable so that a straight line cutting all three curves intersects the related values of each variable.
The noun NOMOGRAM has one meaning:
Meaning #1: a graphic representation of numerical relations
Synonym: nomograph
A NOMOGRAM or NOMOGRAPH is a graphical calculating device, a two-dimensional diagram designed to allow the approximate graphical computation of a function. Like a slide rule, it is a graphical analog computation device; and, like the slide rule, its accuracy is limited by the precision with which physical markings can be drawn, reproduced, viewed, and aligned. Most nomograms are used in applications where an approximate answer is appropriate and useful. Otherwise, the nomogram may be used to check an answer obtained from an exact calculation method.
The slide rule is intended to be a general-purpose device. Nomograms are usually designed to perform a specific calculation, with tables of values effectively built in to the construction of the scales.
A nomogram typically has three scales: two scales represent known values and one scale is the scale where the result is read off. The known scales are placed on the outsides; i.e. the result scale is in the center. Each known value of the calculation is marked on the outer scales and a line is drawn between each mark. Where the line and the inside scale intersects is the result. The scale marks include \'tic marks\' to indicate exact number locations, and labeled reference values. These scales may be linear, logarithmic or have some more complex relationship. Straight scales are useful for relatively simple calculations, but for more complex calculations, simple or elaborate curved scales may need to be used.
Usage is simple — a taut string or other straightedge is placed as to contact the two known values on their lines. The required answer is read off another line. This allows calculation of one variable when the other two are known. Additional lines are sometimes added that are simple conversions of one of the other variables.
One common nomogram that defies the above definition is a temperature graph. On this graph, degrees Fahrenheit and degrees Celsius are both indicated. While it is drawn as a single line with two scales, the two different scale markings indicate that there are actually two lines overlapping each other.

Thank you, Bourth! The suggestion is general enough for this domain without being overly general (merely graphs or curves). I'm curious to know how you came across the term in the first place. 4 KudoZ points were awarded for this answer
