2022-07-18Geomorphic evidence from rivers and lakes can help explain past changes in the locations of archaeological sites as well as environmental and climatic changes in their catchment areas. Examples drawn from the Blue and White Nile valleys in northeast Africa and from the Son and Belan valleys in north-central India reveal how Quaternary climatic fluctuations in the

The significance of engineering geology to construction

01.01.1995The paper discusses the important contribution that engineering geology makes to the construction processes of excavation and the forming of foundations. The contribution to the construction of highways is described.

To avoid undesirable settlement, engineers must predict the settlement under given conditions. The widely used methods are analytical solutions,

Alluvial gold mining in Otago

Alluvial mining is technically simpler than hard-rock mining, so alluvial mining dominated Otago's gold mining history. Alluvial gold occurs as loose particles in the gravel, and is therefore easy to separate because of the high density of the gold. Many of the earliest alluvial mines were extremely rich (10's or even 100's of grams of gold per

Alluvial and colluvial mining is widespread, including reworked gravel beds or raised terraces. Previous work at Mashonga by exploration companies and UNDP/government surveys has placed the bedrock mineralization into one of two main styles: shear zone/vein-hosted or conglomerate-hosted (the Lubare ridge north of Mashonga).

18.12.2008Whereas hydraulic mining delivered high sediment supply to the lower Sacramento River in the late 1800s, the bed has long since adjusted its elevation [Gilbert, 1917; Meade, 1982], and therefore probably its bed grain size [Knighton, 1989] in part due to the self-scouring flood control design implemented in 1917 [James and Singer, 2008; Singer et al., 2008].
