This work focused on the collection and preparation of data required for hydrological modelling Beht catchment area, which covers an area 4560 km 2 with a perimeter 414 km, by combining various spatial technologies, in particular geographical information systems (GIS), remote sensing, digital terrain models (DTM), order to prepare used flood forecasting. The methodology consists, at first, auto...
The U.S. Army Corps of Engineers’ Hydrologic Engineering Center’s River Analysis System (HEC-RAS) is a widely used software application for performing one-dimensional and two-dimensional steady and unsteady flow river hydraulics calculations, sediment transport-mobile bed modeling, and water quality analysis. User’s of HEC-RAS have often unique applications including the coupling with other sof...
Spyridon Orestis Palermos This paper focuses on the hypothesis of the extended cognition (HEC), and in particular, on two interrelated objections to it, namely the coupling-constitution fallacy and the cognitive bloat worry. Briefly, if there is no principled way in which we can decide whether a (cognitive) process depends on extra-neural (or extra-organismic) factors in a causal, or constituti...
Urbanization is a pervasive global trend. The development of residential areas and road network in Hajighoshan watershed (northern Iran) has been observed in the recent several decades. The objective of this study is the quantitative investigation of the effects of impervious surfaces development and urban development on runoff generation and flood hazard. The study of urban area development wa...
the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...
Hydroxyethyl cellulose (HEC) was studied as corrosion inhibitor for mild steel and aluminium in 0.5 M H2SO4 solution using weight loss and electrochemical techniques. The results revealed that HEC inhibited corrosion of mild steel and aluminium in sulphuric acid environment. Inhibition efficiency was found to depend on concentration of the inhibitor. Impedance results revealed that HEC was adso...
abstract the purpose of this study was to find out the effect of applying the principles of group-dynamic assessment (g-da) on learning of conditional structures in english by iranian efl learners at the intermediate level, which according to the formal educational system in iran, includes students who are in their second year of studying in high schools of koohdasht city. this study was a qua...
Bridges are crucial for transporting people and goods, but their failures can be catastrophic, resulting in loss of life property. This study assessed the flood stage selected bridges (Alaafin Avenue, Seven-Up, Oluyole) along Ona River, Ibadan, Nigeria, using a one-dimensional model called Hydraulic Engineering Center-River Analysis System (HEC-RAS). The requires two major input data: geometric...
the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.
