List of top Water Resources Engineering Questions on Crop water requirements asked in GATE CE

The Culturable Command Area (CCA) for a canal is 10000 hectares. The base period for a crop in the CCA is 140 days. Watering depth for the crop is 40 cm. The outlet discharge (in \(m^3/s\)) lies between

An irrigation canal is to be designed to deliver 10 cumec to meet the peak demand of 7500 hectare of cropped area. The estimated canal losses are 50 % of the head discharge. The duty (in hectare/cumec) on capacity of this canal is

During a particular stage of the growth of a crop, the consumptive use of water is 2.8 mm/day. The amount of water available in the soil is 50 % of the maximum depth of available water in the root zone. Consider the maximum root zone depth of the crop as 80 mm and the irrigation efficiency as 70 %.
The interval between irrigation (in days) will be \(\underline{\hspace{2cm}}\) . (round off to the nearest integer)

A reservoir with a live storage of 300 million cubic meters (1 hectare = \(10^4 \, \text{m}^2\)) of a crop with two fillings of the reservoir. If the base period of the crop is 120 days, the duty for this crop (in hectares per cumec, round off to integer) will then be \(\underline{\hspace{1cm}}\).
