2. a ditch
3. a bank of earth formed of material being excavated
4. a causeway
5. a low wall or fence, especially of earth or stone, for dividing or enclosing land
If any of those seems right, just add the river part to it and you got your little definition of River Dike. Hoped I could help.

Dikes
Levees, dikes.
The sumerians used dikes and ditches.
Dikes are built by engineers and construction workers to prevent flooding by controlling the flow of water in rivers, lakes, and coastal areas. The construction of dikes requires careful planning, engineering expertise, and maintenance to ensure they remain stable and effective in protecting against flooding.
The Netherlands (The Dutch built the dikes):-)
Dikes and sills are intrusions.
Netherlands invented Dikes & Windmills
They needed dikes to control flooding.
Dikes are walls, or 'levees ' to stop rivers flooding.
The word in waterway control can be written as dyke or dike. In the US, we use dike. A dike or dikes are a system of levees that control the level of water in a river or other waterway. Dikes control the height and flow of water beyond the point of the dike. When more than one dike exists, the plan can be called a Dike System or System of Dikes.
Igneous rock makes dikes and sills. Basalt or Diabese Dikes are actually usually composed of dolerite.
Dikes were used in china and all over the world for controlling floods
