  • Probabilistic determination of microcatchment area for rain-fed tree cultures 

    پدیدآور نامشخص (Shiraz University, 2006-01-01)
    In this study a simple simulation model for the design of microcatchment water harvesting systems for rain-fed tree cultures in the Bajgah area, Fars province, I. R. of Iran, was developed. The actual daily evapotranspiration ...

  • Incorporating rock fragments in soil erosion models: a case study, the answers model 

    پدیدآور نامشخص (Shiraz University, 2006-01-01)
    Many researchers have incorporated the effects of rock fragments in soil erosion studies to improve the prediction of erosion by raindrop impact and overland flow. According to the Box-Simanton approach, the effect of rock ...

  • Investigation of scour depth at bridge piers using bri-stars model 

    پدیدآور نامشخص (Shiraz University, 2006-01-01)
    BRI-STARS (BRIdge Stream Tube model for Alluvial River Simulation) program was used to investigate the scour depth around bridge piers in some of the major river systems inIran. Model calibration was performed by collecting ...

  • Streamflow time series modeling of Zayandehrud river 

    پدیدآور نامشخص (Shiraz University, 2006-01-01)
    Multiplicative seasonal autoregressive integrated moving average models are appropriate for the monthly stream flow of the Zayandehrud River in western Isfahan province, Iran, through the Box and Jenkins time series modeling ...

  • Experimental modeling of dune bed form in a sand-bed channel 

    پدیدآور نامشخص (Shiraz University, 2006-01-01)
    Resistance to flow is an important and primary parameter in the determination of water surface elevation. A variety of bed forms, especially dunes, have a sensible effect on total roughness. Because of the complexity of ...

  • ENSO forcing on climate change in Iran: precipitation analysis 

    پدیدآور نامشخص (Shiraz University, 2006-01-01)
    An investigation was conducted to detect the change-point years in the Southern Oscillation Index (SOI) and precipitation time series inIran for the period 1951-1999 (49 years). Due to the unavailability of data, the record ...

  • Varied flow through system of gutters and grates 

    پدیدآور نامشخص (Shiraz University, 2006-01-01)
    An adaptation of the Newton Method is used to solve the combined system of ordinary differential and algebraic equations that describe the spatially varied flows that occur from lateral inflow with periodic outflow along ...

  • Stability and vibration of elastically supported, axially moving orthotropic plates 

    پدیدآور نامشخص (Shiraz University, 2006-01-01)
    In this study, the vibration and stability of orthotropic plates, moving on elastic foundation or elastic supports and subjected to in-plane forces, are investigated by classical plate theory. Firstly, a solution based on ...
