The impact of the tsunami has basically diminished after a day and night, although the accumulated water in the city has not receded, the water level has already begun to decrease.
Of course, the pace at which the water level is dropping varies distinctly between the inner and outer districts.
The decline in the outer district's water level is primarily due to natural drainage. The seawater backflow brought by the tsunami has halted, and the original river channels are starting to resume their drainage function, assisting in dispersing the accumulated waters in the outer district.
However, due to the severe rise in water levels, even though the river channels have resumed drainage, the accumulated water is still too deep, bringing minimal improvement.
In contrast, the situation in the inner district is somewhat better.
Initially, the presence of city walls and the buffer zone of the outer district meant the inner district had lighter accumulations than the outer district.
