Many of the huge structures like New Esna, and New Nega Hammadi Barrages face a great harmful caused by local scour downstream (DS) their stilling basins. It is planned to redesign many of these structures to minimize these harmful impacts of the DS local scour. This research paper presents the results of an extensive experimental investigation on using an optimized submerged curved deflector t...

agriculture is one of the main sectors affected by climate change. although recently some studies about the nature and size climate change effect on the physical variables of water resources and agriculture have been done, however economic perspectives and the role of adaptation strategies have been less studied empirically. the contribution of this study is modeling real economic behavior of s...

in current paper, geometrical relationship between the longitudinal faults of a zone of the folded zagros, surrounding asef mountains (north of shiraz) that follow the northwest-southeast structural trend (eg. zarghan, katah and sadra faults) has been studied. a western and southern zone of zagros mountain chain called folded zagros has a length of about 1375 km and a width between 120 and 250 ...

16. Abstract This project uses statistical methods to analyze traffic congestion of the upper Mississippi and The main purpose of this project is identifying and evaluating non-structural alternatives (those not requiring construction, but rather procedural or policy changes, for instance, congestion fee, excess lockage time charges, helper boats, switch boats, deck winches, and moorings) that ...

This research analyzes the incidence and efficiency of impact deflectometry to evaluate design road reinforcements a section central highway. For this study, non-destructive methodology has been used, based on collection, processing, interpretation deflections measured surface with deflectometer equipment; these reflect response structural package under given load, its measurement is simple, fa...

Purpose The purpose of this study is to investigate the structural changes needed for project-based organisations (PBOs) synthesise their project operations and services following servitisation strategy. It addresses question how PBOs should change organisational structure fitting with service provision Design/methodology/approach This followed an exploratory research method using a single in-d...

Understanding the characteristics of vessel traffic flow is crucial in maintaining navigation safety, efficiency, and overall waterway transportation management. Factors influencing vessel traffic flow possess diverse features such as hierarchy, uncertainty, nonlinearity, complexity, and interdependency. To reveal the impact mechanism of the factors influencing vessel traffic flow, a hierarchic...

introduction: in modern societies, shift work is an essential component of daily life. since the beginning of research in shift work, researchers have been engaged in the identification of factors predicting adjustment and adaptation to shift work. the concept of adaptation and tolerance refers mainly to the biological response in terms of circadian rhythms and performance efficiency as well as...

Grassed waterways placed in high water flow zones substantially reduce erosion in agricultural fields. A recent study proposed a statistical model for waterway planning for a farm in the Outer Bluegrass physiographic region of Kentucky. The logistic regression model identified where channel erosion was likely to occur based on elevation-derived terrain attributes. The objective of this study wa...

Introduction Rivers are one of the most important water resources and it is very important to study their water quality. Therefore, in this study, sampling was done from 15 permanent waterway stations of Pirbadush and Gashun of Qolyan River in Lorestan province, which are located in the path of oil shales.   Materials and Methods  Hydro-geochemical parameters were calculated by analyzing t...
