Following catchment area includes 20-years of annual rainfall data. If the catchment average rainfall is to be calculated in each year using the Thiessen Polygon method or the Isohyetal method, explain the method you select and reasons. Consider that the both are area-average methods and give reasonably similar answers when the rain gauge network is dense as shown in the figure
