pondage

The right wall protects a less populous district, with at least 17,000 acres of "pondage" land set aside to hold floodwaters.

The use of some form of automatic spillway gate, limiting the surcharge on the spillway crest during passage of floods, can convert flood surcharge pondage to active pondage, thereby increasing net storage capacity.

This includes pondage of water for fish culture or small scale lift irrigation of specialty crops

Chapter 14 1995

Construction of farm ponds can be undertaken by the cultivator himself The spillway problem is minimized due to the very small size of the catchment involved, the whole storm runoff generally being accommodated in the pondage.

Chapter 16 1995

The means of doing so have already been discussed (outlet control valve, elevated regulating tank, or surface pondage with supplementary lift).

Chapter 17 1995

Storage within the tertiaries, by increasing their sectional area to provide elongated overnight pondage, has been tried but only once.

Chapter 12 1995

The proviso is adequate pondage capacity in the regulating tank.

Chapter 17 1995

Pumping either into or out of the pond would generally be required, and the pondage created by embankment construction, occupying a significant area.

Chapter 12 1995

However, the surface tank or small earthen reservoir, with second stage of lift, provides the ultimate in flexibility as the pondage capacity can be relatively large and the cycle time with one sub-system only taking water can be an hour or more.
