| Zusammenfassung |
| The effects of ditch water management regimes on water tables are examined
for two test sites in England, Halvergate in the Broads and Southlake Moor in
the Somerset Levels and Moors Environmentally Sensitive Areas. It is observed
that in some fields the effects of water management are only poorly transferred
from the ditch to the field centre, especially where the hydraulic conductivity
of the subsoil is small. Where there are large variations in the ditch water
levels, reflecting the influence of major ditches subject to pump drainage,
field soil water regimes differ significantly. Nevertheless, the effects of even
quite small changes in the ditch regime cam be noticeable. Simple modelling
studies show that much greater effects can be achieved by increasing the
frequency of ditches within wetlands. |
