Analyses of areal variations in the subsidence and rebound occurring over stressed aquifer systems, in conjunction with measurements of the hydraulic head fluctuations causing these displacements, can yield valuable information about the compressibility and storage properties of the aquifer system. Historically, stress-strain relationships have been derived from paired extensometer/piezometer i...

Shohada (Sepah) avenue in Qazvin, a historic city, is a part of Safavid era infrastructure of the city. It connects various important cites and poles like Jame' mosque, Imamzadeh Hosein, Dowlat-Khaneh and the Traditional Bazaar complex to one another. This axis in KhomarTashi, in Kabir Jame' mosque - preservation and restoration of Jame' mosque complex as principle core of the city which is ...

introduction water is the most important parameter in the development of human societies. one of the pillars in the development of water resources is the investigation of environmental conditions and environmental compatibility of the project. identification of the areas vulnerable to pollution can play a major role in development strategies. in most areas of iran, located in the arid and semi-...

Groundwater is among the most important resources of drinking water supply ofthe worldwide population. Use of recharge area is one of the methods for artificiallyrecharging groundwater. Selection of suitable sites for artificial recharge is very importantand must be carried out accurately. There are different types of land use, only rangelandsare appropriate for artificial recharge because of t...

Aquifer information carried by aquifer test data may be affected by the presence of a finite thickness skin around the wellbore. The mathematical treatment for an aquifer accounting for the skin zone can be characterized by five parameters, that is, the outer radius of the skin zone and the transmissivity and storativity for each of the skin and aquifer zones. Sensitivity analysis was performed...

in recent years, space syntax theory has been used for analyzing spatial configurations; these analyses mostly focus on social aspects. according to the space syntax theory, space arrangements affect the space usage in buildings. this paper aims at studying spatial configurations of some traditional houses in iran in terms of flexibility factor. besides of having the housing function and provid...

Groundwater in coastal areas is commonly disturbed by tidal fluctuations. A two-dimensional analytical solution is derived to describe the groundwater fluctuation in a leaky confined aquifer system near open tidal water under the assumption that the groundwater head in the confined aquifer fluctuates in response to sea tide whereas that of the overlying unconfined aquifer remains constant. The ...

Groundwater is a reservoir of fresh water located beneath the ground surface in soil pore spaces and fractures lithology formations. contained aquifer layer has certain depth. Aquifer measurement was conducted with five tracks using AGI Super Sting R1 IP tool spacing 25 m track length 675 Balangan County. This study aims to determine 2D cross-sectional model, analyze types, depth, thickness, ty...

with respect to population growth and agricultural development in ardabil plain, vulnerability assessment of the plain aquifer is necessary for management of groundwater resources and the prevention of groundwater contamination. in this study, vulnerability of ardabil plain aquifer to pollution was evaluated by drastic method. drastic model was prepared by seven effective parameters on vulnerab...

This paper presents an analytical model characterizing unsteady groundwater flow in an unconfined aquifer resting on a sloping impervious bed. The aquifer is in contact with a constant water level at one end. The other end is connected to a stream whose level is increasing form an initial level to a final level at a known exponentially decaying function of time. Moreover, the aquifer is repleni...
