Reservoirs with favorable climatic conditions can be used for creating in their zone sanitary-resort complexes, rest homes, holiday hotels, pioneer camps, sports and tourist facilities, water-sports centers, beaches, for organizing hunting lands, and zones of sport and amateur fishing. For example, and analysis of the statistical data indicates an increasing influx of tourists to the Krasnoyarsk, Sayano-Shushenskoe, Brest hydrostations, and the Volga and Dnepr hydrostations [2]. This comparatively new function of reservoirs should also be taken into account when the question about the effectiveness of creating hydrostation reservoirs arises.

Procedures, algorithms, and software applications are developed for automated design of complex waterpower projects. Purposes and Methods of Geometric Modeling in Design of Structures at Pumped-Storage Power Plants (PSPP).In the planning and feasibility assessments of various types of water-power projects, the following modern computer techniques are currently in widespread use: threedimensional solid-body simulation of comparable projects, automated plotting of sections, plans, and profiles of the structures under consideration, and determination of the volumes of work associated with their installation [1,2]. Use of new design techniques makes it possible to automate the work of the designer, for example, to obtain any isometric and perspective projections, sections, cross sections, and profiles of the equipment and structures; to develop photo-realistic representations of the project under design; and, to determine the linear dimensions, perimeters, areas, volumes, and mass-information characteristics of the structural designs and equipment components [3,4]. Developing geometric models of structures under design, and corresponding applied software, it is possible to automatically satisfy any graphical and computational design procedures. Elimination of manual labor with the exception of the Kuhlman drafting unit guarantees high-quality drawings, and fulfillment of requirements of regulatory documents (GOSTs, Departmental Instructions, etc.) as a supplement to user experience and qualification.There currently exists a large selection of graphics packages that can be used in design practice. Such software products as "Mechanical Desktop 2004" -a universal package for parametric solid-body simulation of three-dimensional bodies and surfaces in machine building, "Autodesk Inventor" -a systems package for the spatial design and simulation of machinery and mechanisms, "Autodesk Architectural Desktop" -a graphics system for the design of projects related to industrial and civil construction, and "MapInfo Professional" -a geoinformational system intended for informational support of adoption of design solutions, are successfully used in design organizations of appropriate profile. These graphics systems are specialized, and do not fully correspond to the many-faceted water-power problems encountered by profile design institutes.A design system in the "AutoCAD" medium [5, 6] -the popular universal basic graphics package, which can be used throughout the entire world by many design organizations in different fields, has come into the most widespread use in water-power engineering. It is considered the most flexible graphics system for different branches of design. The data format (dwg) developed by the Autodesk Co. is the generally accepted world standard for exchange of graphical information. The package contains basic resources for two-and three-dimensional design, and possesses developed potential for programming and adaptation. The "AutoCAD" interface can be changed in accordance with user demands. Some built-in pro...
