Some thinking from the talk by Prof. Gan

Prof. Gan is one of the most influential person in the world who has been contributing to the issues of water resources and irrigation. He gave a talk in the seminar today. He proposed a novel and exciting research result which can reduce the desertion along the coastal area. Prof. Gan found that the horizontal infiltration is about 4 times greater than the amount of vertical infiltration at the irrigation area, especially for farms of paddy rice. In addition, he also mentioned that the illegal groundwater extraction at farmland of vegetables is prevalent now. It can cause the significant drawdown of groundwater levels and thus the ground level residence.
These findings can be exciting for some potential further research.
For example, the illegal pumping detection and the amount of horizontal flow estimation.
