Aggregate stability is one of the main factors controlling topsoil hydrology, crustability and erodibility. A tentative discussion of these topics may start with considerations on the nature of aggregated topsoils and changing microstructures which h

Experiments were carried out in a 20 m long flume to assess the variation of the runoff erosion resistance of a loamy soil as a function of initial moisture content and compaction. The results of seven experimental runs show that the runoff erosion r

Erosion and soil degradation form an increasing threat to land throughout the world. The severity of this threat is difficult to quantify as basic data have not been collected or analysed. In this Chapter the present condition and future perspectives

In general, it is accepted that primary loess deposits are undifferentiated and consequently are not laminated or bedded. Redeposition by running water, after primary eolian sedimentation, can produce laminated deposits. Redeposition by splash action

Summary Analytical and progressive rainulator experiments allow one to build up a stemflow equation for grasses and similar herbaceous plants. The predictive value for this equation has been tested by subsequent measurements on simulated sods. The fo

Summary Data on soil erosion by runoff at the Sde Boqer experimental site, northern Negev, Israel, indicate that runoff erosion is unlikely to transport coarse material over the treads of bedrock steps. Detailed field observations led to the idea tha

The Hortonian model of runoff flow which had been thought to be applicable in arid areas has previously been shown not to be valid, notably in Israel, where inverse relations have been observed between slope angle, and runoff discharge and slope eros

In earlier papers the authors discussed several micromorphological and textural characteristics of loamy afterflow deposits derived from loess material and formed during overland flow without splash. This discussion is completed by considering the cr

This paper discusses the environmental and the soil mechanical conditions for the massive planar slides which ravaged the area of Caraguatatuba, Serra do Mar, in 1967. Special attention is given to the hydrology of slopes on weathered gneiss during d
