    Sealing, crusting and cracking of crusts of the soil surface has been observed in many parts of the world in areas with sandy, silty and loamy soils. Sealing and crust formation occurs under the influence of rain storm and drying weather. With prolonged drying, surface crusts might crack, leading to complex situations with respect to infiltration and runoff generation. Cracking of crusted loamy soils appears to be a general process. This study aims to measure the hydraulic properties of fully crusted and cracked-crusted areas and to evaluate the effects of these measurements on catchment discharge and soil loss in a loess region of the Netherlands, using the LISEM soil erosion model. Samples with minimum infiltration rates (fully crusted) and with maximum infiltration rates (cracked-crusted surfaces) were taken from fields with bare soil or winter wheat and their soil hydraulic functions were measured. The results of these measurements were used as input in the LISEM soil erosion model. Simulations of discharge and soil loss were done for each of these two land-uses and for two rain events. Additionally, simulated discharge and soil loss under actual recorded land-use were calculated. In all cases, soils with no surface cracks produced higher figures for discharge and soil loss than those where 10% of the surface crust was cracked. For a good interpretation of the results for soil loss, the spatial distribution of cracked-crusted areas and fully crusted areas has to be investigated in detail. To deal with cracked-crusted and fully crusted areas in simulation modelling, care has to be taken to accurately measure the soil physical functions representing the maximum and minimum infiltration rates. An assignment of these functions to calculation grids has to be made. As the LISEM model is capable of assigning different soil physical functions to each calculation grid, an improved prediction of the soil physical behaviour of the catchment can be simulated.

    The dynamic process of swelling and shrinkage in clay soils has significant practical consequences, such as the rapid transport of water and solutes via shrinkage cracks to the subsoil, and the destruction of buildings and roads on clay soils. In order to develop measuring methods and computer simulation models to take swelling and shrinkage processes into account in agricultural and environmental studies, experiments were conducted on soil aggregates, small soil cores, with a lysimeter, and in the field.

    Determination of shrinkage characteristics of soil aggregates revealed some clay soils from the Netherlands to be among the strongest swelling and shrinking soils of the world with a maximum volume decreases upon drying of 49 %. Normal shrinkage and residual shrinkage are significant within pressure head ranges occurring in field conditions. Shrinkage was isotropic for all horizons of a heavy clay soil, at overburden pressures corresponding to field loads.

    The shrinkage behaviour of a clay soil in a lysimeter may be explained by the occurrence of structural shrinkage, normal isotropic shrinkage and residual isotropic shrinkage. Field experiments confirmed this picture. A newly developed equation to relate vertical soil movements to water content changes during structural, normal, residual and zero shrinkage, for any shrinkage geometry, was successfully applied in the field.

    The obtained knowledge about the swelling and shrinkage process was used to develop a computer simulation model, FLOCR, to calculate the water balance of a clay soil, including preferential flow through shrinkage cracks, on a daily basis. Besides, crack volume and surface subsidence are computed. Model calculations for a heavy clay soil during 1985 were in good agreement with field observations. Comparing FLOCR with a rigid-soil model showed a considerable influence of shrinkage cracks on the soil water balance, on the groundwater level and on the topsoil bearing capacity. The simulation model was also applied to predict the effect of drainage on actual swelling and shrinkage processes in a heavy clay soil profile.

    Finally, the principles of incorporating evaporation from shrinkage cracks, oxygen diffusion in cracking clay soils, and lateral infiltration during preferential flow into the present model approach are presented.

    Alhoewel kleigronden vaak gunstige chemische eigenschappen bezitten, geven de fysische eigenschappen vaak aanleiding tot problemen. Met name de lage doorlatendheden en daardoor de lage infiltratiecapaciteit vooral in natte perioden zorgen ervoor dat de gronden vaak moeilijk en laat bewerkbaar zijn, dat er veelvuldig plasvorming optreedt en dat vaak versmering van de zode plaatsvindt. In hellende gebieden treedt gemakkelijk bodemerosie op, hetgeen echter in Nederland niet of nauwelijks voorkomt. Teneinde inzicht te krijgen in de bodemfysische en hydrologische processen met als doel oplossingen te ereeren voor de genoemde problemen, is het noodzakelijk om naast de uitvoering van veldonderzoek tevens het gedrag van de bodem te simuleren met behulp van modellen. Door middel van simulaties kan niet alleen het gedrag van de grond beter verklaard worden, het gedrag kan binnen zekere grenzen ook voorspeld worden.

    Kleigronden behoren tot de potentieel hoog produktieve gronden van de aarde. De fysische eigenschappen veroorzaken echter nogal wat problemen. Wateroverlast, moeilijkheden bij bewerking, vertrapping en verdroging zijn enkele redenen waarom de optimale produktie, zeker in ontwikkelingslanden, vaak niet wordt gehaald. Over deze fysische eigenschappen is nog weinig bekend
