In water-resources engineering, the sizing of reservoirs depends on accurate estimates of water flow in the river that is being impounded. For some rivers, long-term historical records of such flow data are difficult to obtain. In contrast, meteorological data on precipitation is often available for many years past. Therefore, it is often useful to determine a relationship between flow and precipitation. This relationship can then be used to estimate flows for years when only precipitation measurements were made. The following data are available for a river that is to be dammed: Precipitation, cm|88.9 108.5 104.1139.7 127 94 116.8 99.1 Flow, m3/s 14.6 16.7 15.3 23.2 19.5 16.1 18.1 16.6 (a) Plot these data.
