Understanding and mitigating against the impact of land use change and groundwater extraction on groundwater dependant ecosystems (GDE) requires information on the distribution and environmental water needs of these ecosystems. Conventional field based techniques for determining plant water use and plant stress are very labour intensive and time consuming. In this study, we proposed an alternat...
Abstract The negative balance of water reserves and reduce the size of static storage aquifers including the effects of the drought phenomenon is repeated on the status of surface and groundwater resources in Iran including Khuzestan province has had an impact. In this study, using fuzzy and ArcGIS version also better understand the effects created in the statistical period on the aquifer Gotv...
Background and Objective: Groundwater is the primary water source for drinking and agricultural activities in arid and semi-arid regions. Rainfall, land use, geological structure, aquifer mineralogy, and duration of water contact with the environment in the basement are the main factors affecting the chemical quality of groundwater. This study aimed to determine the physicochemical properties o...
Historical drainage improvements have created complex hydrological regimes in many low-lying, wet coastal grassland areas. The manipulation of ditch water levels is a common management technique to maintain important in-stream and in-field habitats in such areas. However, in wet grasslands with low soil conductivities the water table in the centre of each field is not closely coupled to variati...
The development of agriculture and industry and the increase of population in countries with arid to semi-arid climates have led to more harvesting of groundwater resources and as a result land subsidence in different parts of the worlds. Decades of groundwater overexploitation in the Kashmar-Bardaskan plain in the north-east of Iran has resulted substantial land subsidence in this plain. The p...
