    'Staff publications' is the digital repository of Wageningen University & Research

    'Staff publications' contains references to publications authored by Wageningen University staff from 1976 onward.

    Publications authored by the staff of the Research Institutes are available from 1995 onwards.

    Full text documents are added when available. The database is updated daily and currently holds about 240,000 items, of which 72,000 in open access.

    We have a manual that explains all the features

Abstract Due to grassland evapotranspiration groundwater levels can be lowered decimeters below ditch water
level. Use of submerged drains reduces the lowering of groundwater levels and so peat oxidation and
subsidence and CO2 and N2O emissions. Submerged drains proved to increase the bearing capacity,
however, also the penetration resistance for a meadowbird beak increased. The capacity to capture
rain shower events increased. Groundwater and ditch water quality slightly improved. The infiltration
of ditch water increased considerably, however, was less than expected. Probably this is caused by a
hindered infiltration into the drain by sludge in the ditch. The use of a collector drain to regulate the
inlet is recommended.
