Two dams in China's Inner Mongolia collapse after torrential rain - China has more than 98,000 reservoirs used to regulate floods, generate power and facilitate shipping. More than 80% of them are four decades old or older, and some pose a safety risk, the government has acknowledged.

The flow rate into the reservoir can be exceptionally high due to
extreme local rainfall and rainflow that feed it.

The volume of rain water flowing into the reservoir can be too much for
the embankment structure which was built 40 years ago.

The technology on concrete has improved over the years. A lot more can
be done to strengthen older structures.

As more torrential rains evolved from climate change, the need for man-made
drainage tributaries winding through reservoirs, dams and dykes, are
necessary to regulate the speed of flow rates and the pressure of flow outs.

This is in order to relieve and divert high-pressure water from older dams
and reservoirs which may have been damaged by over-stressed concrete
embankments.

By having this, upstream diversions of waters to new reservoirs,
tributaries, and dams could be created and made.

By that, it will help to stream-line into different streams of diversion of
water flow-outs and flow-rates to a variety of water required in different
dry areas needed in north of China.

By having more upstream tributaries and intermediate storage reservoirs that
could be built along the way in up-streaming and channelling of water flow
outs and flow rates into a re-circulatory water flows.

Hence, by having a circulatory water flow from escaping to the sea, it can
prevent excessive water from torrential rains from wasted to the sea.

Therefore, we can call this circulatory water economy. This is a circulatory
economy that can provide circulatory economic gains for the country of
China.

This is because precious fresh water can be flowed everywhere in China to
maximise the need for water circulation in China.

"Dykes"?

China won't care. About 1.5 billion nowadays and
very tight control of 'reality'. What are a few
thousand dead ? Didn't happen. Nothing to see here.
