In IEEE Std 952-1997 (Annex C) we find the answer to this. They have a fancy integral relation between Allan Variance (\$\sigma^{2}\$) and Power Spectral Density. If \$K\$ is the random walk coefficient of which you speak, they show that
$$\sigma^{2}(\tau) = \frac{K^{2} \tau}{3}$$
So
$$\sigma(\tau) = \frac{K \tau^{0.5}}{3^{0.5}}$$
The 0.5 power on \$\...
