QUESTION 1 Create ONE PROGRAM to calculate the average depth of precipitation using THEISSEN POLYGON METHOD in python. a) Draw a flowchart to demonstrate the algorithm design of the program to calculate the average depth of precipitation. b) Write a complete python code in python based on the flowchart constructed in QUESTION 1 (a). Please use Data and Example calculation style for this methods refer below: 2. Theissen Polygon Method: This method is very accurate. It is used for basins having areas between 500 - 5000 km. This method can be best understood with the help of Fig. 2.7. Fig. 2.7. The por me The firm closing line shows a basin having an area between 500 to 5000 sq km. Let there be rain-ganging stations A, B, C, D, E and F. It is assumed that each station has its own domain in the total area. While finding out the average value of rainfall it is very essential to divide the total basin area in such a way that each station enclosed in a particular area represents that area in true sense The values can now be tubulated as shown below: Table 24 Station Rainfall in CH Area of Plan in a Weled depel af minjal 4 (2) SEM 1 A 26 4x T) E F 1 To explain the procedure, column: (1) Shows the various rain-gauging stations, column ADVERTISEMENTS (ii) The amount of rainfall at each station, column, (iii) Gives area of each polygonal domain of the stations and column, (iv) Gives weighted depth of rainfall which is obtained by multiplying values in columns and 3 Now, mean depth of rainfall = (column No. 4)/(3 column No.3) ADVERTISEMENTS Column number 3 = Total area of basin = a +b+c+d+e+f Mean depth of rainfall = (5.6a + 4.95 +5.2c +5-40 x 5.50 +5-2f)/(a +6+c+d+e+f) QUESTION 1 Create ONE PROGRAM to calculate the average depth of precipitation using THEISSEN POLYGON METHOD in python. a) Draw a flowchart to demonstrate the algorithm design of the program to calculate the average depth of precipitation. b) Write a complete python code in python based on the flowchart constructed in QUESTION 1 (a).
