There is no information on costs associated with this measure, which will be very
case-specific.

esign
This measure can be treated as an integral part of ‘re-naturalising’ a catchment,
and hence may fit with a range of other measures to restore the natural functions
of rivers, especially Reconnection of oxbow lakes and similar features (N7).

The length of temporary streams may
vary from a few hundred metres to mul-
tiple kilometres.
Seasonal streams or intermittent rivers are rivers for which surface water naturally
ceases to flow
at some point in space and time. They comprise a large
proportion of the global river network and are characterised by dynamic exchanges between terrestrial and aquatic habitats. The abundance and distribution
of seasonal streams and their natural intermittent flow regimes are being altered by climate change, water abstraction and inter-basin transfers. Restoring and
reconnecting them with the river contributes to favouring the
overall functioning
of the river by restoring lateral connectivity, diversifying flows and providing
water retention during floods.
