Drainage and cultivation of the Orinoco Delta

Due to the horizontality of the plain and the overabundance of land, a huge waterway can be built, always on the 100-meter coast. If it was 1 km wide and the levees were 10 meters high on the bottom of the bed, it could output 10,000 m3, a much higher figure. But it could be perfectly 2 km or 3 km wide. The width does not matter. It is not a channel in peneplain territory, which must be narrowed.
On the contrary, in the middle of the horizontal plain, what matters is that the dikes are kept at a constant height and that the bottom of the bed maintains a minimum slope for the water to flow. In this sense, the work does not present any difficulties and is perfectly feasible.
With respect to the Orinoco, the problem is extremely simple: it is a colossal work, but the result is that which can be derived from the distribution of 5,000 m3 / s of water for irrigation. They are 100 million hectares; in reality, between 100 and 150. The region would become one of the great granaries of the World. In turn, it would be able to absorb large masses of population, relieving social tensions in the countries of the area. This region would have an exit to the sea directly, outside the mouth of the Orinoco. I would be in depression between the mountains of Caracas and those of Cumana.
