This is an unexpected and very important progress in the actual metering of small overflow levels with weirs. |

|
The foundations have survived to the present thanks to the artificially-raised ground of around 7 m, which were required in the 13th century after the construction of weirs on the Vltava. |
|
Working with the villagers, Hazare started a water conservation program that included land forestation and building weirs, which greatly improved the water supply. |
|
|
In practice, wide crested weirs are used as so-called low overfalls. |
|
There its flow is interrupted by a number of anicuts or weirs. |
|
It reminded me of environmental aids like weirs and gabion boxes. |

The route of the new canal was much the same as that of the first since the channels and locks of the original canal became the control weirs of the new works. |

The construction of fish ladders around dams and weirs, and the release of extra water into important breeding grounds, has spawned a recovery in native species. |
|
The flow of rivers is regulated by weirs and dams. |
|
They have also built stone weirs across these canals at regular intervals, to slow the current down still further and encourage water to spill over the canal banks. |
|
It contains the final five weirs before the navigable section is reached. |
|
In late medieval times, salmon weirs hindered free passage on the river, but the Wye Navigation Act in 1662 enabled the river's potential to be developed. |
