As special depositional environments which are adjacent to the seas, deltas have provided a field for human habitat establishment. Geomorphic features of deltas are in constant transformation due to their dynamic features. Constructing dams on rivers can intensify these changes and cause either negative or positive consequences. Minab delta in Hormozgan Province of Iran is a round or crescent-s...

through a collection of cooperative agents called ants, the near optimal solution to the multi-reservoir operation problem may be effectively achieved employing ant colony optimization algorithms (acoas). the problem is approached by considering a finite operating horizon, classifying the possible releases from the reservoir(s) into pre-determined intervals, and projecting the problem on a grap...

genus acomys comprising 14 species from mouse like rodents and substituted in murinae subfamily. the aim of this research was surveying external, cranial and dental character differences among diverse populations of acomys dimidiatus in minab, boushehr and geno biosphere reserve. sampling was performed during summer 2003 and 2005. total of 52 species were collected from mentioned sites. the res...

Standardized Runoff Index (SRI), as one of the well-known hydrological drought indices, may contain uncertainties caused by employment distribution function, time scale, and record length statistical data. In this study, uncertainty in SRI estimation monthly discharge data 30- 49-year lengths from Minab Dam watershed, south Iran, was investigated. Four probability functions (Gamma, Weibull, Log...

Climate change and human activities are two major drivers that alter hydrological cycle processes cause changes in spatio-temporal distribution of water availability. Streamflow as the most important component hydrologic is expected to be influenced by climate well activities. Three methods including sensitivity procedure, slope ratio cumulative quantity modeling SWAT investigated compared for ...

Petro physics, rock physics and multi-attribute analysis have been employed in an integrated approach to delineate porosity variation across Tamag Field of Niger Delta Basin. Gamma and resistivity logs were employed to identify sand bodies and correlated across the field. Petro physical analysis was undertaken. Rock physics modelling and multi-attribute analysis were carried out. Two hydrocarbo...

a key parameter for the application of polymer gels in water shut off treatment is the adsorption of polymer gel onto the rock surface. so, the adsorption properties of a nanocomposite hydrogel were discussed in this research by crosslinking of sulfonated polyacrylamide/sodium montmorillonite aqueous solutions with chromium triacetate. the x-ray diffraction patterns indicated that exfoliated ty...
