This also means the lager the drainage basin the longer the lag time which can be referred to hydrograph B. Hydrograph A represents to a great extent likely a small drainage basin where the water only has to travel a short distance. The shape of a drainage basin also plays a part in determining the lag time of a hydrograph. In a long drainage basin...If you want to get a entire essay, order it on our website: BestEssayCheap.com
