At the first stage of a hydro-power survey of a river, it is important to select the optimal hydro-power site. The most important condition to be satisfied is to determine the optimal site where the greatest and most economical amount of hydro-energy can be obtained. This paper proposes a new method in which the optimal arrangement of the hydro-power stations is determined by a computational operation using discrete data at points along the river such as the drainage area, altitude, and distance along the river channel as obtained from topographical maps instead of drawing on engineers’ experiences and the intuitions of experts. The results by this method are then compared with data on existing hydro-power stations and the results planned by expert engineers to show that this new computational method is superior.

Inland Ice

Glaciological investigations have been carried out in areas proposed for local hydro-power stations in Greenland, A mapping programme was set up, to provide data for mass balance and simulation of run-off, as well as glacier dynamics.Two types of glacier map have been produced, covering the margin of the Inland Ice: detailed photogrammetric maps, based on plotting from vertical aerial photographs and a new type of surface feature map, based on digitally-processed Landsat data. The photogrammetric maps, plotted on a scale of 1:25 000, include surface topography and surface features, such as crevasses, lakes, moraines etc. The surface feature maps, plotted on a scale of 1:100 000, show surface features related to ice and melt-water drainage, as well as subtle, topographic features, related to the subglacial topography.The maps have so far been used for preliminary delineation of drainage areas on the Inland Ice and for planning tracks of radio echo-soundings.

Jinping I Hydropower Station

The left bank slope in JinpingⅠhydropower station is one of the highest slope with the maximum excavation and the worst stability conditions in the current hydro power stations in the world. Based on the combination of the elasto-viscoplastic finite element method and artificial neural networks, a model of back analysis of the mechanical parameters of slope is established. In this paper, the left bank slope (II1-II1) in JinpingⅠhydropower station is taken as an example．Construction procedure and anchor measures are simulated carefully; the key mechanical parameter of rock is back analyzed according to the monitored displacement; the real time forecast of deformation and stability of the rock slope are realized by this model based on the monitored displacement. Most of research results are taken as the references for the optimization of design and information construction in the practical engineering．
