Knowing how the low flow changes upstream and its trend provides valuable information on water resources management, water rights, and the improvement of crop patterns. It also helps to identify suitable areas for water control management along the river from water resources management perspective. In addition to economic issues, the preservation of river ecosystems is an important matter that ...

Background: Unsustainable development of agriculture and aquaculture has reduced the water quality of rivers. The most important aim of this study is assessing of water quality in the Ghezel Özan basin in Zanjan province. Method: 18 sites were selected based on standard criteria including land use, geology, biodiversity points, accessibility and standard distributions. Content of Dissolved Oxyg...

In a watershed, land use As one of the most effective factors in basin hydrologic response, Can have significant role in the hydrological cycle and water resources. The knowledge of the effects of land use change on basin hydrology responses can help to determine the appropriate strategy to achieve sustainable development of water resources and a management model. The purpose of this study is t...

This research was conducted to develop relationships among evapotranspiration (ET), percolation (PERC), groundwater discharge to the stream (GWQ), and water table fluctuations through a modeling approach. The Soil and Water Assessment Tool (SWAT) hydrologic and crop models were applied in the Big Sunflower River watershed (BSRW; 7660 km(2) ) within the Yazoo River Basin of the Lower Mississippi...

Climate change is a global issue that draws widespread attention from the international society. As an important component of the climate system, the water cycle is directly affected by climate change. Thus, it is very important to study the influences of climate change on the basin water cycle with respect to maintenance of healthy rivers, sustainable use of water resources, and sustainable so...

Efficient water use is the key for sustainable management of water resources. The major reason of non-efficient management of water resources, especially in developing countries, is nonavailability of reliable hydrological information about the actual water used by different agricultural crops with in a large irrigation system or at the basin scale. Therefore, an estimation of spatially distrib...

The excessive focus on water mounts a challenge to the sustainable development. Energy is another aspect that should be taken into account. Nexus approach is characterized by an equal emphasis on energy and water spheres. In arid areas, like the city of Kashan, Iran, non-conventional waters (e.g. desalinated and recycled waters) have been considered as an alternative resource of water. Nexus wa...
