The last mob had the bright idea of lining up boats in the Chao Phraya and using the propellers to force the water to flow backwards and therefore prevent floods.
This plan was flawed as they were only dealing with the surface water, leaving the deeper waters to continue flowing undisturbed, so it was bound to fail.

However, I do rest assured that the new boss has this totally under control as he has a new fleet of submarines, which can deal with the deeper waters.

You obviously missed the latest developments on this.  As the rivers are not really deep those big subs from China might require dredging. Instead it has been decided to use midget submarines.

Please note that this project started before Elon Musk tried to butt in with his gadget. 

"Thailand to develop midget submarines

Jon Grevatt - IHS Jane's Defence Weekly
24 July 2018

A project by the Royal Thai Navy (RTN) to develop a midget submarine – provisionally known as the Chawalan class – has been approved by the Thai government, it has been confirmed to Jane’s .

Under the project, the RTN has been allocated THB200 million (USD6 million) to develop and build a submarine prototype over the next seven years. Initial research on the project started in late 2017.

The design and development of the midget submarine will take four years, with a further two years to build the prototype and an additional 12 months to undertake trials and evaluations.

If the project is successful, construction of the platform is expected to commence in the mid-2020s."
