  • Autographic rain-gage network design for iran by kriging 

    پدیدآور نامشخص (Shiraz University, 2001-01-01)
    Autographic rain-gage networks are designed to provide the density and distribution of stations so that characteristics of the rainfall events both in time and over the region concerned can be determined with sufficient ...

  • Buckling modes of plate assemblies with variable thickness 

    پدیدآور نامشخص (Shiraz University, 2001-01-01)
    A semi analytical procedure based on the bubble finite strip method for the elastic buckling problems of thin-walled structures with variable cross section thickness is presented. The method is programmed to investigate ...

  • Finite element modeling of flows in open-channel transitions 

    پدیدآور نامشخص (Shiraz University, 2001-01-01)
    To analyze flows in channel expansions and contractions, two-dimensional, depth-averaged, unsteady flow equations are solved by using the two-step Taylor-Galerkin scheme. The 2-D, depth-averaged equations are written in a ...

  • An improved numerical algorithm to simulate the interaction of nonlinear water waves with a fixed large cylinder 

    پدیدآور نامشخص (Shiraz University, 2001-01-01)
    The diffraction of nonlinear water waves around a fixed large surface-piercing body of arbitrary shape is solved in three-dimension numerically using second order perturbation theory. A time domain panel method is applied ...

  • An investigation into the risk of piping at dams in the Urmia region, Iran 

    پدیدآور نامشخص (Shiraz University, 2001-01-01)
    Six diversion dams in Shar-Chai, Nazlu-Chai, and Baranduz-Chai rivers in Urmia plain, Urmia, Iran, were selected to investigate their safety against piping. The analytical model was based on a PIPING code based on Sellmeijer's ...

  • The joint probability method of determining the flood return period of a tidally affected pond 

    پدیدآور نامشخص (Shiraz University, 2001-01-01)
    In this paper a method is presented to determine the return period of flood levels within detention ponds used to store surface water runoff for affected coastal catchments. A simulation method is proposed in probability ...

  • Prediction of sediment transport in littoral zones 

    پدیدآور نامشخص (Shiraz University, 2001-01-01)
    In this paper, the longshore sediment transport in littoral zones is investigated. For investigation of sediment transport in the nearshore zone, the effects of waves, currents and topographical conditions of the coast, ...

  • Relating the usda and isss soil particle size distributions 

    پدیدآور نامشخص (Shiraz University, 2001-01-01)
    Different systems are in use for texture classification of soils. The two most common systems originated with the International Soil Science Society (ISSS) and the United States Department of Agriculture (USDA). These ...

  • Uncertainty in the design and simulation of reservoirs 

    پدیدآور نامشخص (Shiraz University, 2001-01-01)
    Insufficient information associated with historical data may require utilization of time series techniques, which in turn would result in record generation with sources of uncertainty. This type of effect can be evaluated ...

  • Use of a self-cementing fly ash as a soil stabilization agent 

    پدیدآور نامشخص (Shiraz University, 2001-01-01)
    The increasing trend towards electrical power generation through coal combustion has aggravated the problems associated with disposal of the fly ash produced as a by-product. Due to the pozzolanic properties of fly ash, ...

  • Vertical and horizontal seismic microzonation by microtremor asurement 

    پدیدآور نامشخص (Shiraz University, 2001-01-01)
    One of the methods by which one can state the dynamic characteristics of the soil of an area, is by the measurement and analysis of microtremors. In this paper microtremors have been measured on 143 sites located in the ...

  • Winter rainfall in iran: enso and aloft wind interactions 

    پدیدآور نامشخص (Shiraz University, 2001-01-01)
    The effect of the El Oscillation (ENSO) phenomenon on winter rainfall in Iran was explored for the period 1951-1995. The interactions between this phenomenon, aloft wind in Tehran and the rainfall were also investigated. ...
