Base flow is a portion of stream flow that is not directly generated from the excess rainfall (i.e.the volume of rainfall available for direct surface runoff and which is not

evapotranspired)during a storm event. In other words, base flow describes the flow conditions that would exist in the stream without the contribution of hill slope runoff resulting from the rainfall via fast hill slope runoff delivery mechanisms. What is the baseflow(https://en.wikipedia.org/wiki/Baseflow) level in the stream right before the first storm begins (i.e. at the inflection point of the first storm's rising limb)? Based on our hydrology lectures, what are the likely hydrological mechanisms (pathways) that contribute base flow to the Speed River (4 marks)
