  • Comparative calculation of irrigation networks using Labye's method, the linear programming method and a simplified nonlinear method 

    Theocharis, M. E.; Tzimopoulos, C. D.; Sakellariou-Makrantonaki, M. A.; Yannopoulos, S. I.; Meletiou, I. K. (2010)
    The designating factors in the design of branched irrigation networks are the cost of pipes and the cost of pumping. They both depend directly on the hydraulic pump head. It is mandatory for this reason to calculate the ...
  • Design of optimal irrigation networks 

    Theocharis, M. E.; Tzimopoulos, C. D.; Yannopoulos, S. I.; Sakellariou-Makrantonaki, M. A. (2006)
    The problem of selecting the best pattern of pipe diameters of an irrigation network has long been given considerable attention by engineers when designing hydraulic works. The classical optimization techniques, which have ...
  • A New Analytical Model to Predict the Hydraulic Conductivity of Unsaturated Soils 

    Tzimopoulos, C. D.; Sakellariou-Makrantonaki, M. (1996)
    A new analytical model is presented for the prediction of hydraulic conductivity. The new model is based on the Brutsaert characteristic curve psi(theta) and the Mualem integral relation. It is presented by a series expansion ...
  • SOIL WATER MANAGEMENT PROBLEM USING FUZZY ARITHMETIC 

    Halkidis, I. N.; Tzimopoulos, C. D.; Evangelides, C. H.; Sakellarioy-Makrantonaki, M. (2009)
    Drainage management problems are usually very hard to simulate due to the uncertainty of the hydraulic parameters involved. Fuzzy analysis is one of the available tools that can be used for such problems, involving uncertain ...
