I have total 4 arrays.
waterdepth = [] (10 values)
velocities = [] (corresponding to the 10 values of depths)
time=[] (10 values)
velocities = []=(corresponding to the 10 values of time)
I am able to plot two graphs seperately but I want to show how velocity is changing with both waterdepth and time in a single 3D plot.... How can I plot one?

Do the values in waterdepth correspond in any way to the values in time?

Not really... For a fixed waterdepth I have 10 velocity values at 10 different time points
And at a fixed time point I have 10 different velocity values at 10 different depths
But as said, depths do not correspond to time in any way ...

As you have 3 vectors waterdepth,time and velocities, you can plot a 3D scatter plot by making use of scatter3 function.
Refer to the documentation of scatter3 function
