Problem - 100 cm of precipitation fall each year on a 400 hectare farm. According to estimates, 20% of precipitation travels as runoff to the nearest watercourse and 40% of precipitation evaporates back into the atmosphere. The aquifer receives the remaining precipitation by percolation. All through the year, the aquifer is used to extract water for irrigation. Approximately 80% of the groundwater that is removed eventually evaporates. Determine how much groundwater recharge—measured in cubic meters—can be taken out annually for irrigation without dwindling the groundwater supply.
g. How does the crop water requirement vary with stage of crop growth and season of the year? h. A discharge of three cubic meters/second is diverted from a river in to a canal. Of this amount, 2.25 cu.m/s are delivered to the farms. Surface runoff from the irrigated areas averages about 450 liters/sec. Percolation to groundwater amounts to 300 liters/sec. What is the conveyance efficiency and application efficiency? i. State three conditions which lead to very low water application efficiency in most lowland rice farms in the Philippines.
