Glacial terminus position. Given a simple glacial valley with a slope of 0.01, such that the elevation of the bed z = 3500 – 0.01x, a uniform valley width, and a mass balance profile b(z) = 0.01*(z-ELA), where the equilibrium line elevation ELA = 3000 m, calculate the expected terminus position for a steady glacier. The maximum elevation of the valley, at x = 0, is 3500 m. Calculate and plot the down-valley pattern of ice discharge.
