Subject: Does temperature of stream water affects stream velocity?

Hi
I am a 3rd year Geography student from National University of Singapore.  
I am currently doing a project on water temperature of 1) the stream water 
and 2) the surroundings and their effect on the velocity of the stream 
water.  Will the temperatures really affect the velocity of the water?  As 
you know, Singapore do not have four seasons but we do have different 
temperature for the day....  For example, the hottest of our day is from 
12-2pm and the coolest is at night when the sun had set.  Will the 
temperatures really affect the velocity of the stream water? 

Thank you.  Your help will be greatly appreciated
