2. For the channel described in problem #1, calculate the total bed-load transport (bed load) using Einstein's bed-load transport equation for (1) each individual granulometric fraction and (w) for all fractions together, taking an equivalent diameter. This is the Problem 1 A long channel of rectangular cross section has a bed slope of 0.0005. The channel bed is composed of near-uniform granulate of die = 0.7 mm with a porosity of 0.4. The normal flow depth was measured as 210 m. This channel enters a lake, at the juncture the water levels of the channel and of the lake are the same The water level in the lake in the lowered by Ah = 0.15 m. Determine at what time the channel bed will be lowered by 90% and by 50% of shat 1.5 and 20.0 km upstream of the juncture.
