a) Following are the Infiltration capacity data obtained in a flooding type infiltration test for an irrigation project. Table Q 3.1 With the aid of appropriate graphs, analyze and obtain the best values of the parameters in Horton's infiltration capacity equation to represent this data set. (10 marks) b) Irrigation department is in a process to do a reservoir operation for a reservoir in Anuradhapura for a capacity enhancement to increase the irrigable area. To estimate the evaporation, Kanthale station data (Reference Crop Evapotranspiration) and the area capacity curve data of the reservoir were used as shown in Table Q 3.2. Calculate the total evaporation in the considered year.
