introduction: time series models are generally categorized as a data-driven method or mathematically-based method. these models are known as one of the most important tools in modeling and forecasting of hydrological processes, which are used to design and scientific management of water resources projects. on the other hand, a better understanding of the river flow process is vital for appropri...

The agricultural sector is of particular importance in the city of Bijar. Thus, the economic value perunit of water applid to the side effects of excessive groundwater resources in this area has a utmostimportance. Payment for estimation of water on a suitable production function was estimated revenueproducers. Therefore in this study to estimate the economic value of water resources in agricul...

in order to study, the effect of pre-cooling treatment, osmotic potential and water stress on some population of two species of satureja bachtiarica and satureja sahendica was studied by a factorial experiment based on completely randomized design with three replications in laboratory and greenhouse conditions during one year in the gene bank of institute of forests and range lands by the years...

1. introduction floods are among earth's most common and most destructive natural hazards. floods create geomorphic hazards via changes in sediment transport and channel configuration (e.g. channel width, lateral migration, planform changes, etc). in this context, floodplain zoning and its application in spatial planning is important in non- structural measures in order to reducing flood damage...

soil texture is an important soil physical property that governs most physical, chemical, biological, and hydrological processes in soils. detailed information on soil texture variability is crucial for proper crop and land management and environmental studies. therefore, at present research, 103 soil profiles were dogged and then sampled in order to prepare digital map of soil texture in bijar...
