By using the theory of multidimensional Markovian decosopm-making programming to solve the long-term optimal, this paper studied the optimal dis patching of two parallel hydropower reservoirs under without and one-period inflow forecast.

In this paper, the three-dimensional mathematical models for reinforcing steels of galleries are analyzed in detail and established, which will solve the problems of three dimensional display and draft about reinforcing steels arrangement drawings of huge galleries.

The idea and method of design about the reinforcement drawing CAD software of oblique intersection galleries are introduced.

All oblique types of galleries are transformed into simple ones of connection in equal radius and meeting in the formof right angles on the same elevation, thus making the joint types of galleries simple andstandardized.

In this article the process of Yalu River corridor s landscape change was analyzed.

By summarizing corridor functions of urban river and land use practices in urban riparian zone in foreign and domestic cities,influence exerted by riparian land use on urban river corridor is analyzed,and a case study is conducted in Suzhou Creek in Shanghai.

The desert oasis is actually the river corridor and its area affected,whose water is mostly from the supply of river flow,and the amount of the water released directly influences the safety of river corridor.
