The contamination of 15 ground water resources of a selected region earmarked for the emergency supply of population has been monitored. The resources have been selected on the basis of previous assessment of natural conditions and the exploitation of territory in their surroundings and infiltration area. Two resources out of 15 have been excluded from further exploitation, because they have no...

according to the current state of water resources and the increasing demand for water, the supply of future needs will be faced with serious constraints. on the one hand, the failure to supply sometimes causes social and political problems. on the other hand, improper exploitation of water resources will lead to irreparable damages. therefore, the use of optimization models for the planning of ...

Groundwater vulnerability assessment is of crucial importance for land use/cover management. Some methods have been proposed specifically for the karst hydrogeological settings. Among them, COP and PaPRIKa, as two commonly applied recent methods, were adopted for the resource vulnerability assessment of a humid temperate karst region, north of Iran. Comparison of water bacterial content and dis...

rangelands renewable resources play a very important role in ecosystem regulating, preserving plant genetic reservoirs, water cycle as well as providing large parts of forage requirements. these resources were considered to be a basis for sustainable development and also a basic platform for various economic activities. during the recent years in iran, these valuable sources were subjected to s...

The oceans are a crucial source of natural resources for human development, as productive terrestrial resources increasingly reach their limits of economic and ecological exploitation. With increasing human impact on oceans, it is vital to maintain a sustainable human–ocean relationship. We present an indicator system and information entropy model to assess the evolution of human–ocean systems ...

the management of water table is introduced as one of the major parts of the solutions in water resources management. this method could play a significant role in protecting water resources, increasing irrigation efficiency, preserving nutrients in soil, and protecting the quality of surface downstream, and as well, of groundwater. towards this end, a laboratory study has been done on the effec...
