Like bar syrups, it is a 2:1 sugar and water mixture, but has an added ingredient of gum arabic. Gomme syrup is made with the highest percentage of sugar to water possible, while the gum arabic prevents the sugar from crystallizing and adds a smooth texture.yrup can be used as a sweetener. However, since the syrup jells readily when pectin is added, its primary culinary use is as a base for fruit sauces, toppings, and preserves. Combining Demerara sugar, a type of natural brown sugar, with water produces Demerara syrup.
Runoff ratio is the runoff for each watershed divided by the precipitation for that watershed. It is the proportion. of rainfall that does not infiltrate and is not taken up by evapotranspiration, and thus ends up as runoff.
The basis of the curve number method is the empirical relationship between the retention (rainfall not converted into runoff) and runoff properties of the watershed and the rainfall.
