rose water residues are by-products of rose water industries. these residues do not have any industrial usage and they are returned to soil as crop fertilizer. in this research, the effects of adding rose water distillation residues to soil in different particle sizes and weight proportion were investigated and changes in mechanical strength, and water holding capacity of soil and the growth of...

wetlands are ecosystems with specific features and functions which have been unfortunatelydamaged by recent pressures and limitations. fast reduction of surface flows, water and wind erosion of soil,changes in the quality of water and soil resources, increasing exploitation of underground water, agriculturaldevelopment, climate change, etc. have had the most effect on these ecosystems. so this ...

the increasing need for water in the arid areas of the world has resulted in the emergence of wastewater application for agriculture and landscape. using treated wastewater in agricultural irrigation can provide more adequate supply of high quality water for human consumption, but their heavy metal applications effect must be regulated to ensure no physiological problems for both the plant and ...

limitation of water resources in iran motivates sustaining and preserving of the resources in order to supply future water needs. fulfilling these objectives will not be possible unless having accurate water balance of watersheds. the purpose of this study is to estimate the water balance parameters using a distributed method. the large number of distributed models and methods was studied and “...

GSFLOW is a new U.S. Geological Survey model for simulating ground-water/surface-water interactions. GSFLOW couples PRMS (the Precipitation Runoff Modeling System) to MODFLOW (the Modular Ground-Water Model) with modules for simulating flow and storage in unsaturated-zones, lakes, and streams. GSFLOW simulates infiltration, runoff generation, and lateral flow in temporarily saturated material (...
