Evaporation.
A significant, but lesser amount, is also lost to percolation in the transfer ditches, unless they are lined with something impermeable, like concrete.
carrying irrigation water into fields through open ditches waste water
When water is carried into fields in open irrigation ditches, much of it is lost to evaporation, seepage into the ground, and runoff. These losses contribute to inefficiencies in water use and can lead to water scarcity issues. Implementing more efficient irrigation methods like drip irrigation can help reduce these losses.
the water was diverted by digging ditches in the ground going through the fields, when the tied of the river raised then it would travel down these ditches, the ground would then soak it up and the plants would suck it in. The ditches were called aqueducts.
Carrying irrigation water through open ditches can waste water due to evaporation and seepage, leading to loss of water before it reaches the crops. Additionally, open ditches are prone to leaks and spillage, further contributing to water wastage. Efficient irrigation methods like drip or sprinkler systems can help minimize water losses.
A lot of the water is lost through evaporation.
Irrigation really started in Ancient Egypt when the pharaohs used ditches to move water from the Nile River to the crop fields.
By trapping water in dams and weirs, and leading irrigation channels through the fields.
they dug irrigation ditches from the river to their fields so they could bring water to their crops.

The Egyptian irrigation ditches brought water from the River Nile to water food crops growing along the Nile Valley.
Li Bing's biggest problem while building the irrigation ditches was the massive amount of silt and debris carried by the Min River, which continuously filled up the ditches. He solved this by constructing a special dividing weir known as the "Fish Mouth" to help divert the silt-laden water away from the irrigation system.
