[en] In this article we provide an analysis of algorithm prepared for the purposes of making forest mask from aerial multispectral photos with high resolution. The photos were taken on 10"t"h September 2011 in the area of Hydropower plant Gabcikovo in the section Dobrohost - Bodiky in different spectral bands - blue, green, red and near- infrared. We also illustrate the use of progressive and evolving method of object-based classification and the use of this method in classifying forest structures, in our case in the process of forest mask creating. The result of this article is an algorithm, which is useful while creating forest mask. The overall accuracy of algorithm achieved 89.5%. (authors)

[en] Utilization of hydro-power as renewable energy source is of prime importance in the world now. Hydropower energy is available in abundant in form of falls, canals rivers, dams etc. It means, there are various types of sites with different parameters like flow rate, heads, etc. Depending upon the sites, water turbines are designed and manufactured to avail hydro-power energy. Low head turbines on runof-river are widely used for the purpose. Low head turbines are classified as reaction turbines. For runof-river, depending upon the variety of site data, low head Kaplan turbines are selected, designed and manufactured. For any given site requirement, it becomes very essential to design the turbine runner blades through optimization of the CAD model of blades profile. This paper presents the optimization technique carried out on a complex geometry of blade profile through static and dynamic computational analysis. It is used through change of the blade profile geometry at five different angles in the 3D (Three Dimensional) CAD model. Blade complex geometry and design have been developed by using the coordinates point system on the blade in PRO-E /CREO software. Five different blade models are developed for analysis purpose. Based on the flow rate and heads, blade profiles are analyzed using ANSYS software to check and compare the output results for optimization of the blades for improved results which show that by changing blade profile angle and its geometry, different blade sizes and geometry can be optimized using the computational techniques with changes in CAD models.

[en] This paper describes the contractual and financial aspects of the Mrica Project. Of particular interest is the high degree of cooperation that developed between the various parties, and the effect this had on the progress and completion of the project. This relationship had its origin in the need to make the best use of the relatively scarce funds available. It was vitally important that problems were solved jointly and that costs did not escalate as a result of confrontation between the parties. In this respect, the project was an early manifestation of the contractual relationship now called partnering, and the procedures adopted at Mrica are very similar to those now widely used in partnering contracts. The paper is therefore structured to identify and analyse the key elements of co-operation, and their impact on both the negotiation of the contracts and the completion of the works. (Author)

[en] A hydroelectric power plant is proposed for the Coulonge River, a tributary of the Ottawa River in Quebec. Water would be taken from the river through a 609 m tunnel to the plant, which would contain two Francis turbines with a total installed power of 16.2 MW operating under a net head of 43 m and a water flow rate of 21.5 m³/s. Other works would be necessary upstream for controlling flow and protecting the intake. Total cost for the two-year construction project is estimated at $28 million and annual revenues are forecast at $6 million. An inquiry and public hearing were held to consider the biophysical, social, economic, and cultural impacts of the proposed hydroelectric project. Results of the hearing are summarized in such areas as legal aspects, environmental quality, water rights, land use, job creation, effects on tourism and recreation, effects on wildlife, water level fluctuations, water quality, and safety. The economic justification for the project is discussed with reference to electricity demand, economic viability, utilization factors, and policies that favor construction of small-scale hydroelectric plants. The project was not found to bring sufficient benefits to the region in which it was to be situated and would not be authorized unless Hydro-Quebec tariff policy with respect to small hydro plants was modified and unless the project sponsor compensates the regional municipality. 13 refs., 11 figs., 4 tabs
