alternative variation
1.Abstract: Variation of flow condition caused by the multi-pur pose regulation schemes has been investigated on the basis of measured date in r iver model.Flood-control of the upper river,operation of the power-station,saf ety of the bridge and power-station,navigation and evolution of the river are a nalyzed.A reasonable and feasible project alternative and the improvement measur ement are proposed.
2.Based on the unique linear facies variation,bimodal volcanic rocksuite and the alternative horst and graben structures which arecontrolled by inherent great fracture zone in NE direction, theauthor first suggests there was an aulacogen series with sinistralstrike--slip tension during Devonian Period and preliminarilydiscusses the relationship between the aulacogeu series and strata-bound deposits.
