Survey Details |
|
2.1
Dates of erosion monitoring survey: |
1981-1985 |
|
2.1
Water/wind erosion? |
Water |
|
2.3
Area monitored: |
Central
Belgium |
|
2.4
Character of area: |
Hilly
area with silty loamy soils, mainly arable land |
|
2.5
Frequency of monitoring: |
Rill
erosion rates were measured in the Spring (i.e. after the Winter
season) |
|
2.6
What fraction of fields in the monitored area were included
in the survey? |
<1% |
|
2.7
How were estimates of erosion made? |
Volumetric
in case cements were made and converted to soil loss rates.
Only rill erosion was measured. Spatial resolution of measurements
was relatively high |
|
2.8
Were air photographs used? |
No |
|
2.9
For each erosion site, information recorded: |
Rill
volume, topography, vegetation cover, surface state (degree
of crusting), crop type.
Bulk density, soil shear strength, grain size distribution,
aggregate stability, organic matter content of top soil |
|
|
2.10
Data obtained from elsewhere: |
|
|
2.11
Data calculated from above information: |
Soil
loss rates. |
|
2.12
Meterological station density and type: |
Daily
precipitation values were available from KMI, Belgium on 3-5
stations (spaced ca. 20 km) in the area |
|
2.13
Length of record of meterological data: |
150
years |
|
| 3.
Associated Work |
|
3.1
Associated experimental or plot-based work: |
Work
on all development and interrill processes on the Muldenberg
field site |
|
3.2
Associated modelling work: |
Establishment
of a statistical model describing the affect of topography,
soil type and vegetation cover on rill development |
