The most comonly accepted explanation about these "liquid like" dark streaks is that they are dust avalanches. The process is as follows: every day a thin dust descends on mars ground (which was carried in the atmosphere by dust devils and large storms). This dust is light colored, a bit reddish. It accumulates on slopes too, but when it reaches beyond the equilibrium point, an avalanche occurs. This avalanche may be very thin, about a some millimetre dust layers. But when it flows, it left the darker terrain under to appear, creating these black streaks which strangely look wet, but are not. It is in the frame of this explanation that I commented above.
