To brighten the stream, I applied a Levels adjustment layer in clipping mask:
Then create a Hue/Saturation adjustment layer to change the colour of the stream to blend in with the ground:
Open Brook 1 stock and select the part shown in red and place it above the stream 2 layer.
Add a layer mask for it and with a soft brush of low opacity around 45-50%, mask away the unwanted parts as shown below:
Apply a Hue/Saturation adjustment layer in clipping mask and reduce the Saturation to -50 as the brook is too bright compared with the whole scene.
Next, open the 'Brook 2' stock, select the part shown in the preview below using a rectangular marquee tool, copy (C) it over your main document above the 'Brook 1' layer.
Then apply the Warp transform tool as shown below:
Make a layer mask for it and taking a soft brush of opacity about 45%, mask away the unwanted parts as done with the other previous layers:
Darken the brook and add a bit of contrast by applying a Levels adjustment layer in clipping mask. Fill it's layer mask with black (Alt+Backspace- when the Foreground color is black) and taking a soft brush with the foreground colour set to white, bring back the effect of the Levels layer from the part shown in the selection below:
Create a second Levels adjustment layer, this time to brighten some parts of the brook. Fill it’s layer mask with black and taking a soft brush with the Foreground color set to white, reveal back the Levels effects from the selection shown below:
Create a Vibrance adjustment layer (set as a clipping mask) and decrease the Vibrance to -16 and Saturation to -17 :
Duplicate (Cmd/Ctrl+J) the 'brook 2' layer, activate the free transform tool (Cmd/Ctrl+T) and apply Flip Horizontal. And place it at the far right corner of the scene as shown below:
Just like we did with the previous layer, create a Levels adjustment layer in clipping mask to darken the brook layer.
Fill the layer mask with black and then taking a soft brush -100% opacity and with foreground color set to white, reveal back the Levels effect from the part indicated by the selection:
