-The primary intention of the rain gauging in hydroelectric work is to determine the monthly and annual rainfalls over catchment area. When the rain-gauging stations are more than one for a particular basin, calculation of average rainfall depending upon the area of the basin is done.
-The Thiessen method is based on the assumption that measured amounts at any station can be applied halfway to the next station in any direction, which means that for any point rainfall is equal to the observed rainfall at the closest gauge.
-The isohyetal method is used to estimate the mean precipitation across an area by drawing lines of equal precipitation. The method uses topographic and other data to yield reliable estimates. Isohyets are contours of equal precipitation analogous to contour lines on a topographic map.
