Why don't you plainly generate your hollow semi-cilinder ? It's really very simple to generate the coordinates, and you also have full control of the shape.
In my opinion, for such a simple problem you shouldn't bother using 3d-party models. Your scene will be composed of 2 objects: a) the water-channel b) the water itself. a) For the water-chanel, you need 2 objects, the Geometry object (you can use a QuadArray) and an Appearance object. Being wire-frame or textured solid is only playing with the attributes of the appearance (actually PoligonAttributes and TextureAttributes). Once the geometry created you don't have to change it. b) for the water, I'll use a TriangleArray to generate a polygon mesh in BY_REF mode and create a behavior to dynamicaly change the mesh. Here you can use some simple algorithms to change the coordinates / normals of the mesh to simulate the waves of a running water. The water should have transparency attributes set, so that you can see through it. If you really want to play with something realistic, then the water pipe should have two texture unit states, one for the plain texture and the second texture should contain the refracted light passing through the water. Then in the same behavior you should also change the texture transform of the refracted light so that it's synchronized with the water mesh.
