The impact of mining has also been demonstrated on the interfluves and in the headwaters of streams, where extensive upland swamps have very noticeably dried out, and in some cases destroyed, as a result of subsidence and fracturing of the solid sandstone base on which they rely (NSW Dept.
Within the Orang Rimba kindred of relations, which is generally confined to neighboring river interfluves, cousin marriages pull cognates in danger of becoming non-cognates back into a network of kin and social relations, and builds bonds of solidarity between people of the same generation level, within the confines of very asymmetrical relations of affinity (Sather 1996: 90).

Undoubtedly sources of groundwater that contribute to ditch flow are not so much controlled by the subtle interfluves defining surface catchments as they are by water table depth, subsurface features (e.
