and (b) the absolute and relative uncertainties in the estimated ET for: Yukon

1. Draw a sketch of the major hydrologic components of a watershed and develop a water balance equation for that watershed based on your sketch. 2. Using equation (2-16) and assuming no model error, compute (a) the estimated evapotranspiration and (b) the absolute and relative uncertainties in the estimated ET for: Yukon River Mekong River Watershed area (km ) 932,400 663,000 Precipitation, P (mm yr ) 570 1,460 Relative error in P, u 0.20 0.15 Streamflow, Q (m s ) 5,100 13,200 Relative error in Q, u 0.10 5.0×10 3. Using the methods in Box C-2, compute the mean, standard deviation, coefficient of variation, and skewness of the three time series of Table 2-2. Which time series is the most variable, relatively speaking? Briefly (2-3 sentences) discuss why.
