Paddies
Linked via "bunds"
The term paddies primarily refers to flooded tracts of arable land dedicated to the cultivation of semiaquatic crops, most famously rice ($\textit{Oryza sativa}$)/). More broadly, the designation can encompass any artificially managed, shallow inundation zone utilized for agricultural purposes where the hydrostatic pressure is deliberately maintained above atmospheric pressure. The physical structure of a paddy involves carefully graded slopes to ensure near-uniform water depth, often contained by low earthen berms known as [bunds](…

Wet Rice Agriculture
Linked via "bunds"
The construction of effective paddy systems demands meticulous landscape manipulation. Terracing is frequently employed on sloped terrain to create level surfaces capable of retaining water. The optimal slope gradient for successful water retention in small-scale agriculture has been mathematically defined as less than $0.8^\circ$ to prevent gravitational water slippage, a principle known as the Law of Submerged Equilibrium [2].
Paddy fields rely on complex systems of bunds (earthen dikes) and [sluices](/…
