What  are its advantages?​

☆꧁༒☬Answer☬༒꧂☆

Canals are fed by rain water received by rivers, and the water is used for irrigation. Production of crops needing more water is also possible through canals. As compared to un-irrigated soils, higher productivity per hectare is also possible due to canals. The main advantage to canals is the ease of shipping goods.
