maharlou-bakhtegan catchment in the southern part of iran is faced with water scarcity.this problem is exacerbated by environmental degradation, climate change effects, mismanagementof water resources, along with a major dependence of water demand supplies on the limitedgroundwater resources. in this study, a combined approach of dpsir model along with the scenarioanalysis was employed to deriv...

in the recent decades, due to water shortage problems, most countries have adopted their new policies from water supply management to water demand management . the main objective of the present study is a simulation of water market in order to determine the role of market in the balance between water supply and water demand and to analysis impacts of irrigation water sharing policies on the cro...

due to shortage of precipitation and the spatial and periodical disparity of rainfalls, iran iscounted among the arid and semi-arid countries of the world, and therefore the water utilities have put thecontrol of consumption and efficient use of water high on their priorities. water consumption management isconsidered as a field of energy management, and the impacts of effective measure related...

the purpose of this study was to investigate the challenges of agricultural water management from farmers’ viewpoint. the statistical population consisted of 5297 farmers in karaj county. a total number of 142 farmers were selected applying cochran’s formula. the sample was drawn using stratified sampling method with proportional allocation. to collect data, a questionnaire was developed. to en...

Due to its location in the dry belt, the vast country of Iran has always been faced with the problem of water shortages. In such a climate one should take measures to increase the productivity and improve the efficiency of irrigation through expansion of water-conserving technology in the agricultural sector, as this is the largest and most important consumer of water. Therefore this study aime...

abstarct precise knowledge of all components of water balance is essential to optimize water use in irrigated agriculture. however, water balance components are difficult to measure in required time intervals because their measuring is time consuming and costly. unsaturated zone simulator models are useful tools for predicting the effects of agricultural management on crop water use and can be ...

Agricultural-induced increase of nitrate (NO3) loading in groundwater is a worldwide problem. This study investigates the impacts of agricultural activities on groundwater NO3 pollution in a Yellow River irrigated region. The agricultural land use patterns are dependent on the land and water conditions. Besides wheat–maize rotation, the most popular cultivation pattern, other patterns with high...
