The plan area of a reservoir is 1 km2. The water level in the reservoir is observed to decline by 20 cm in a certain period. During this period the reservoir receives a surface inflow of a 10 hectare-meters and 20 hectare-meters are abstracted from the reservoir for irrigation. The pan evaporation and rainfall recorded during the same period are 12 cm and 3 cm respectively. The pan-co-efficient is 0.7. Find the seepage loss from the reservoir during this period in hectare-meter –
