“…For the forested Keuper marl areas, more data are available. Current erosion rates for small catchments are given by several authors (Imeson and Vis, 1984a;Van Hooff and Jungerius, 1984;Duysings, 1987). According to these authors, these small watersheds under forest show suspended solid outputs to be a factor 2-5 lower than for the agricultural watersheds on the same substratum, depending on the watershed studied.…”

“…Some measured sediment yields for watersheds under agriculture exist. For the Mosergriecht (mainly Keuper marl substratum), 1.474, 2.660 and 2.457 t ha À1 yr À1 of suspended load were calculated for 773, 1016 and 946 mm of annual precipitation in the period 1978-80 (Imeson and Vis, 1984a;van Hooff and Jungerius, 1984) equalling surface lowering values between 0.10 and 0.16 mm yr À1 . On some occasions rill and gully erosion occur.…”

In the forested catchments of the Luxembourg Keuper area, deeply-incised valleys have developed in which streambank erosion is a widespread phenomenon. For one of the catchments in this area, the Schrondweilerbaach catchment, a sediment budget was constructed in order to determine the relative contributions of the various channel and valley slope processes to sediment output.Streambanks contributed 53 per cent of the output with bank scour and subsoil fall being the main processes while to a lesser extent bank material was supplied by bank failures, splash erosion, and soil creep. The remaining 47 per cent of the sediment was derived from the valley slopes mainly through the combined action of rainsplash detachment and overland flow transport. During the two years of investigations sediment output from the drainage basin almost equalled sediment input from streambanks and valley slopes. The results of the measurements of the various streambank processes are integrated in a descriptive model for the present-day widening of valley incisions in the study area and used to hypothesize the palaeohydrological development of the basin. Special attention is paid to the (in)direct effects of the forest vegetation on streambank erosion and sediment transport through the stream channel.

For a large part of the year, the forested catchments in the Keuper formation of east Luxembourg produce more direct run-off on a storm basis than paired cultivated catchments. The occurrence of shrinkage cracks, their pronounced opening and closing, and the occurrence of natural pipes in the forested environment play a major role in explaining this phenomenon. The effect of land use on storm run-off is studied in relation to that found for lithology in the same area.KEY WORDS Direct run-off Land use Shrinkage cracks Natural pipes OBJECTIVESThe objectives of this study were (1) to establish the relative quantitative effects of lithology and land use on storm run-off for small catchments in east Luxembourg, and (2) to relate these effects to dynamic hydrological processes observed in the field. EXPERIMENTAL DESIGNA network for measuring rainfall and discharge was designed and established in April 1984 within the Keuper marls and Luxembourg sandstone formation. Precipitation was measured at four sites with Siap tipping bucket recorders mounted 60 cm above ground level, and discharge was measured at six sites using 90" V-notch weirs (Thomson weirs), equipped with either Seba or Leopold and Stevens stage recorders (Figure 1). The catchments were visited at least monthly for 18 months. STUDY AREAForested soils in the Keuper marls are characterized by many large biopores and natural pipes in the surface soil caused by the combined action of root decay and the activity of earthworms, voles and moles, and by a clayey B-horizon at approximately 30 cm, causing a rapid decrease in vertical profile permeability. The Keuper soils under cultivation or pasture differ from those under forest in being truncated to the lower B-or C-horizons. The weathering product of the Luxembourg sandstone, in contrast, is a permeable loamy sand. Information on lithostratigraphy and land use for the studied catchments are presented in Table I and Figure 2. A full description of the fieldwork area is presented in Hendriks (1990). HYDROMORPHOMETRIC DATAAs run-off data are highly correlated with catchment physiography (NERC, 1975), catchment values for a number of hydromorphometricai variables were determined.
