abstract: in this research, the relationship between geomorphologic factors with underground water resources in zahab plain (in west of kermanshah) has been analyzed using by analyzing-deducing and weighting methods. first, by using of pizometeric and exploratory well data, variation of water table in zahab plain has been comparative analysis with geomorphic unites and then, the zahab watershed...

the aim of this study is to investigate underground water quality parameters in gorganrud river basin and their connection with aboveground conditions using gis and artificial neural networks. in order to prepare a land use map of the area, liss iii image of irs satellite of the year 2008 was used in a maximum likelihood classification. the results revealed that there was a significant correlat...

Water distribution networks comprised of underground reinforced concrete pipes deteriorate with time due to environmental conditions, such as chloride-induced corrosion and differential soil movements [1]. If the pipes in these networks are not periodically replaced, they will eventually fail. Strategies for replacement for these pipes depend on 1) the risks associated with failure of a water d...

introduction the special regional and geographical characteristics of iran, the flowof streams with mediterranean regime, topographic status, and diversity of relieves have provided an extensive areafor the penetration of water into the ground. all of these factors together with the shortage of ground water reservoirs have enhanced the significance of ground water in iran. since the volume of g...

Many applications for irrigation management and environment monitoring exploit buried sensors wired-connected to the soil surface for information retrieval. Wireless Underground Sensor Networks (WUSNs) is an emerging area of research that promises to provide communication capabilities to these sensors. To accomplish this, a reliable wireless underground communication channel is necessary, allow...

Many communities obtain their drinking water from underground sources called aquifers. Official water suppliers or public incorporations drill wells into soil and rock aquifers look‐ ing for groundwater contained there in order to supply the population with drinking water. An aquifer can be defined as a geologic formation that will supply water to a well in enough quantities to make possible th...

INTRODUCTION Everyone knows that forest is the source of water for all people who live on Thai soil. We do not have any other source of water in Thailand ... [the forest] provides for underground water storage, making the ground moist as a benefit for all people... The result of cutting forest is the destruction of the water source of the Thai people. (Royal Forest Department/Suan Pa Sirikit, 1...

in recent decades, attention to contamination propagation into soils and underground water has increased, which has led to a rise in the studies on soil contamination problems and methods of in-situ remediation. in this research, effective parameters on oil contamination propagation in soils and underground water have been investigated using fem in order to determine propagation patterns. the m...
