Have we fixed the problem? How effective was the approach? |

Introduction
Monitoring and evaluation are important in management of channel
seepage. See Case studies for examples.
Monitoring of effectiveness
Monitoring the effectiveness of seepage remediation techniques is
essential, both to confirm the seepage reduction achieved initially,
and to assess ongoing performance. Monitoring is closely linked to
the maintenance program as inspections of the site may well provide
the first indication of effectiveness.
In addition to site inspection, the effectiveness of the technique
can be assessed by:
- The procedures recommended in Identification and measurement
- Water
distribution and channel flow rate information and management
- Adjacent
landowner feedback and observations of the adjacent landscape
Where seepage remediation is undertaken to reduce the impact
on adjacent land (e.g. through waterlogging or salinity), it
is important to
monitor groundwater levels. A reduction in groundwater levels
may indicate the success of the seepage reduction technique.
Failure
of groundwater levels to reduce may mean that either the treatment
has not worked (and that it should be checked with a pondage
test) or that factors other than channel seepage are contributing
to
the problem.
| Feedback |
 |
This website provides information and advice about channel
seepage and a Channel seepage decision support
tool, and aims
to highlight
key issues and activities. It also contains a growing information
base to support users and natural resource managers.
We encourage feedback and contributions of further case studies.

| Case
Studies |
|
The IAL trials provided information for development of guidelines
for identification, measurement and remediation of channel seepage.
Information from the trials appears throughout this website.
Two detailed Case studies record the experiences of rural water
supply
managers and operators.
The case studies cover the key trial sites that were used in
the measurement and remediation components of the IAL project.
They
document information used to make decisions, experiences in implementing
solutions to channel seepage, and post-implementation issues.
