WebFlow time [T] = Flow Length [L] / Velocity [LT-1] (1) Flow time [T] = Flow Length [L] * Weight [L-1 T] (2) By combining these equations, you get a new equation: Weight [L-1 T] = 1 / Velocity [LT-1] (3) Thus, you can determine weight using your velocity field layer. Later, you'll use your weight grid layer in conjunction with your flow direction ...
