BundsBunds (low earth banks keyed into the substrate) can be used to retain water on site above the level of the water table in the surrounding land. Bunds permit the creation of tiered wetlands that have constant flow (important for reedbeds). Bunding permits the retention of winter flood water to counter summer deficits, the creation of permanent lagoons and the protection of areas from permanent flooding. Construction follows the same general principles as dam construction but is less complicated and relatively cheap. Bunds should be set well back from the edges of drainage channels to prevent slumping and reduce seepage. Creating mower-friendly profiles is advisable as bunds are often invaded by rank vegetation such as thistles. |
