Rb1 = 9/3
Rb2 = 3/1
Bifurcation Ratio (Rb) = ΣN / ΣN + 1 ΣN = Total number of stream of a particular order. ΣN + 1 = Total number of stream of a next higher order.
You add the number of streams that branch off the main stream which is the first order then you add the number of streams branching off that stream whih becomes the 2nd order and the sum of the no. of stream orders divided by the number of streams gives the bifurcation ratio.

The stream length ratio, bifurcation ratio, and basin length are critical factors influencing a watershed's hydrology and morphology. The stream length ratio reflects the efficiency of drainage, with higher ratios indicating a more complex network that can enhance water flow and sediment transport. The bifurcation ratio, which measures the branching patterns of streams, affects how water is distributed and can impact erosion and sediment deposition. Basin length influences the time it takes for water to travel through the watershed, thereby affecting flood dynamics and water availability.
The bifurcation ration is the relationship between the number of steams of one order an those of the next highest order. It is calculated by dividing the number of streams in one order by the number in the next order. For example , in a basin :N1/N2 = (number of the first order streams / number of second order streams) = 20/4 = 5N2/N3 = (number of the second order streams / number of third order streams) = 4/2 = 2N3/N4 = (number of the third order streams / number of fourth order streams) = 2/1 = 2then, by finding the mean of each rations in the basin being studied :(5 + 2 + 2)/3 = 3 = bifurcation ration for this basin.*** the significance of this ratio is that as the ration is reduced so the risk of flooding within the basin increases. it also indicates the flood risk for parts of the basin.

The interest coverage ratio is the calculation that determines a company's ability to repay debt payments. It is this calculation that determines whether or not companies are able to obtain loans.
Expression of Compound Ratio - x : y : z For example, a calculation of compound ration may be expressed as x:y:z = a:b:c Note that its calculation has to decompose their ratio expression above into the following, x:y = a:b AND y:z = b:c
the concerned calculation goes wrong...
There is no such thing as "difurcation". Please check the spelling, and ask another question, clarifying whether you mean "bifurcation", "difraction", or perhaps something entirely different.
A stream gradient is the grade measure by the ratio of drop in elevation of a stream. It is expressed as feet per mile.
