3D graph with assumptions

Suppose I have f(x,y) that I need to Plot in 3D, however, the range of x is (0,1) while the range of y is (0,g(x)), where g(x) is some explicit function of x, say x^1/2. Is there a way to do it since specifying it directly the way I outlined above in Plot3D gives me the error message that "Plot3D :: plln: Limiting value g(x) in {y,0,g(x)} is not a machine-size real number". Perhaps I can do this indirectly by plotting two surfaces and then consider the relevant part of surface f(x,y), however, it would look ugly. Thanks.
