Internal erosional behaviour of lignosulfonate treated dispersive clay has been studied using the Process Simulation Apparatus for Internol Crack Erosion (PSAICE) designed and built at UOw. Effectiveness of Iignosulfonate treated dispersive clay on the erosion resistance has been investigated and its advantage over traditional admixtures is presented. Test results show that the hydraulic shear ...

The evolution of Earth's climate over geological timescales is linked to surface erosion via weathering silicate minerals and burial organic carbon. However, methodological difficulties in reconstructing rates through time feedbacks among tectonics, climate, spurred an ongoing debate on mountain sensitivity tectonic forcing. At the heart this question whether late Cenozoic cooling has increased...

S U M M A R Y A contourite drift from offshore Brazil is mapped in detail and investigated using state-of-theart 3-D seismic data. The aim was to review the relevance of erosional features in contourite drifts accumulated on continental slopes. Topographically confined by growing salt diapirs, the mapped contourite ridge is limited by two erosional features, a contourite moat and a turbidite ch...

Along the Southern Himalayan Front (SHF), areas with concentrated precipitation coincide with rapid exhumation, as indicated by young mineral cooling ages. Twenty new, young ( < 1–5 Ma) apatite fission track (AFT) ages have been obtained from the Himalayan Crystalline Core along the Sutlej Valley, NW India. The AFT ages correlate with elevation, but show no spatial relationship to tectonic stru...

Storm-driven episodes of gully erosion and landsliding produce large influxes of sediment to stream channels that have both immediate, often detrimental, impacts on aquatic communities and long-term consequences that are essential in the creation and maintenance of certain channel and riparian landforms. Together, these effects form an important component of river ecosystems. In this paper we d...

Introduction: Most studies of martian erosion have focused on crater statistics, aeolian landforms and deposits, and valley network morphology. Previous workers have noted that the martian crater population is deficient in craters less than ~30 km in diameter, presumably due to erosion [1], and that ancient martian craters were subjected to different erosional processes than craters on airless ...
