Review on Solar Energy Development in Tehran

There are abundant renewable energy sources in Iran such as wind, solar, geothermal, biomass. However, Iran is fully dependent on fossil fuels for industrial, residential and transportation sectors. Tehran extremely high level of energy consumption per head of population. Also, air pollution in Tehran is increasing every day. So, the development of novel solar power technologies is one of the best solutions for these problems in Tehran and other cities of Iran. In this paper, first of all, I covered the current state of Iran's energy like fossil fuels and renewable energy resources. Then I described the solar potential energy in Iran and specifically in Tehran with a few case studies. Finally, in conclusion, I described the potential opportunities of Iran over solar energy

Experimental research on breaching of embankment dams due to overtopping

Un barrage est une structure qui est construite sur une rivière pour contrôler l'eau. L'un des types de barrages est un barrage en remblai. Les deux principaux types de barrages en remblai sont les barrages en terre et les barrages en enrochement, selon les matériaux utilisés dans la construction du barrage. La rupture de barrage est l'un des problèmes les plus importants de la structure des barrages. De nombreux facteurs sont à l'origine de la rupture d'un barrage. Le débordement est l'une des principales causes de rupture de barrage. Le développement de la brèche dans le barrage peut causer des dommages irréparables. La rupture de remblai a récemment attiré plus d'attention en raison de l'importance de ce problème. Cette recherche a étudié la rupture d'un barrage en remblai en raison d'un débordement. Cinq essais expérimentaux réalisés en dispositif à flume au laboratoire de l'Université Laval. Un modèle a été construit avec du till romaine 3 (T₁), un modèle a été construit avec du sable pur (T₂) et trois modèles ont été construits avec des mélanges sable-argile (T₃, T₄ et T₅). Le développement de l'érosion pour différents matériaux observé lors des essais de rupture de remblai et l'analyse des résultats sont décrits dans cette recherche.A dam is a structure that is built across a river to control water. One of the types of dams is an embankment dam. The two principal types of embankment dams are earth dams and rock-fill dams, depending on the materials used in construction of the dam. Dam failure is one of the most important problems in dam structure. There are many factors that causes of dam failure. Overtopping is one of the main causes of dam failure. Development of the breach in the dam can cause irreparable damage. Embankment breaching has recently drawn more attention due to importance of this issue. This research studied breaching of embankment dam due to overtopping. Five experimental tests carried out in flume device in laboratory of Laval University. One model was constructed of till of romaine 3 (T₁), one model was constructed of pure sand (T₂) and three models were built of sand-clay mixtures (T₃, T₄ and T₅). The erosion development for different materials observed during embankment breaching tests and the analysis of the results are described in this research

A Review on Potential Applications of Unmanned Aerial Vehicle for Construction Industry

In the recent years, the Unmanned Aerial Vehicles (UAVs) have been greatly used for different construction and operation applications of various types of construction projects. The main purpose of this paper is briefly reviewing the UAVs in the construction industry. In the building and construction industry, sustainable construction involves different issues among them, the design and management of projects can be named. In recent years, different types of technologies helped improve the management of projects; one of them is the Unmanned Aerial Vehicle (UAV). As a real-time capturing of data technology, UAV is used in the construction industry
