Discharge routing as a mathematic process to forecast the changes of greatness, speed and form of flood wave is function of time in one or more points along drainage, canal or reservoir. Hydrologic and hydraulic methods are used to accomplish the flood routing. Although hydrologic method is less accurate than hydraulic methods but it is simpler to use in flood control and designing works with...

Hydrological models for evaluating and predicting the amount of available water in basins, flood frequency analysis, and developing strategies to deal with destructive floods are expanding daily. In this study, HEC-GeoHMS and Arc Hydro extensions in ArcGIS software and the HEC-HMS model were used to simulate design flood hydrographs in the Aydooghmush basin in the northwest of Iran. SCS-CN, SCS...

In arid and semi-arid countries such as Iran, which are always faced water supply problems in various sectors due to climate stress, the importance of surface runoff management in watersheds is becoming increasingly apparent. One of the components of water resources management in each region is the initiatives of people living in and around watersheds based on their indigenous and empirical kno...

this thesis aims at putting together two of the vestest areas of study there is in humanities: bioethics and literature. the two novels in question, oryx and crake and the year of the flood, are considered as some of the most succssful examples of spculative fiction. in these novels the biological and environmental issues raised as looked at from a bioethics point of view.

Today, the preparation of flood zoning maps is one of the basic and important issues in the study of development projects in the world; it is considered before any investment by the related organizations. In this paper, flood zoning was performed using the two-dimensional model HEC-RAS and GIS in order to assess the risk of the construction of a railway station near the bank of the Iranshahr Ri...

     Quantifying the effects of watershed management projects is a first step in the evaluation of their efficiency. Selecting suitable index for evaluation is an important concern in an evaluation process and is determined on the basis of project type, evaluation method, required accuracy, and available data. Watershed management projects have been initiated in Goosh-Bahreh Watershed, Khorasan...
