Spatial distribution of gully head activity and sediment supply along an ephemeral channel in a southern Ethiopia‚ Arbaminch \ Abstract In this study‚ we examined the factors that control the spatial distribution of bank gully heads along a reach of an ephemeral river (Arbaminch‚ Ethiopia) in an area threatened by desertification in Southern Ethiopia. The activity of 58 gully heads was assessed in the field by pre-defined criteria such as sharp edges‚ presence of a plunge pool‚ tension cracks‚

A population of measurements is approximately normally distributed with mean of 25 and a variance of 9. Find the probability that a measurement selected at random will be between 19 and 31. Solution: The values 19 and 31 must be transformed into the corresponding z values and then the area between the two z values found. Using the transformation formula from X to z (where µ = 25 and σ √9 = 3)‚ we have z19 = (19 – 25) / 3 = -2 and z31 = (31 - 25) / 3 = +2 From the area between z =±2 is 2(0
