    Isohytes Gauges Fig. 3.9: Example of isohyetal method 11. Advantages Data from nearby stations located outside the basin can also be used. Spacing of station as well as magnitude of precipitation is considered in the method. The method is more accurate due to the consideration of topography and other influences.A major advantage of this method is that it lends itself very well to a computerized process since the coordinates of the raingages as well as the approximate centroids of the subsreas can be entered as input variables, whereas Thiessen or Isohyetal diagrams are more difficult to construct using computer programs.

    Isohyetal is a imaginary line joiningthe points of equal or same rainfall records. It is most accurate method to calculate average rainfall because division of area is according to actual rainfall records. isohyetal method advantages, Thiessen's Polygon & Isohyetal Methods Thiessen's Polygon Thiessen's Polygon:The Method Locate all rainfall stations on a base map and record the rainfall amount. Connect each station by straight lines with the several nearest stations to form a series of triangles. Erect

    Isohyetal Method An isohyet is a contour of equal rainfall. Knowing the depths of rainfall at each rain gauge station of an area and assuming linear variation of rainfall between any two adjacent stations, one can draw a smooth curve passing through all points indicating the same value of rainfall, Fig. 2.7 (c).

    Arithmetic mean definition is - a value that is computed by dividing the sum of a set of terms by the number of terms. How to use arithmetic mean in a sentence. The use of the method is the first known use outside of China, where it was developed during the construction of the 130m high Jiangya Dam in 1997-8. The sloping of the 300mm thick layers of RCC across the dam from bank to bank at grades between 5-8% ensures subsequent layers of RCC can be placed within the initial set time of the lower layer ...

    3.Isohytel method. An isohyet is a line, on a rainfall map of the basin, joining places of equal rainfall readings. An isohyetal map showing contours of equal rainfall presents a more accurate picture of the rainfall distribution over the basin. Average rainfall can be computed by the following expression. Advantages: The isohytel method is the ...
