This study quantitatively analyzes the effects of flooding on growth and species diversity riparian forests along Yarkant River Tarim River, Xinjiang, in northwest China, provides important information for efficient utilization water resource management arid regions. Monitoring was conducted every year from 2016 to 2019 Xiamale forest district lower reaches Shaya lunnan upper middle River. The ...
Flooding events have been negatively affecting the Republic of Kazakhstan, with higher occurrence in flat parts country during spring snowmelt snow-fed rivers. The current project aims to assess flood hazard reduction capacity Alva irrigation system, which is located interfluve area Yesil and Nura Rivers. assessment performed by simulating floods using HEC-RAS 2D controlling gates existing syst...
To support the transition from traditional flood defence strategies to a flood risk management approach at the basin scale in Europe, the EU has adopted a new Directive (2007/60/EC) at the end of 2007. One of the major tasks which member states must carry out in order to comply with this Directive is to map flood hazards and risks in their territory, which will form the basis of future flood ri...
Using seasonal floods is very important in arid and semi arid areas. Suspended sediments in the flood are caused changes in soil properties. The aim of this study is to investigate the soil chemical and physical properties affected by low quality floods irrigation. Sampling from three phases, in each phase three points (beginning, middle and end of the row) and in the depths of 30-0, 60-30 and ...
Bandsar is a traditional and Intelligently method of exploiting floods in arid and semi-arid areas, which can be implemented in a wide area with the participation of watershed residents. This structure, in addition to controlling floods and feeding the aquifer, expands flood agriculture in the region, and by collecting sediments from floods, it leads to soil enrichment. To this end, in this res...
The morphostratigraphy of flood plains along unconfined reaches of the Todd River, central Australia, indicate that flood plain formation is dominated by high magnitude floods. Processes of flood plain destruction include channel widening, vertical stripping, flood channel, back channel and macroturbulent scour. Flood plain construction occurs predominantly during high magnitude floods. Overban...
The disparate spatial and temporal distribution of rainfall in the country and climate variation sometimes leads to rivers flooding and large flood events, which are remarkable for life and financial losses. Flood control design requires accurate knowledge of the flood generator basin, especially smaller ones, in large basins. Determining the potential of flood generation to specify the...
-Water plays an important role in everyday’s life. Agriculture is a backbone of our country and it uses 85% of available fresh water for irrigation. Irrigation is the method of supplying the water to the plants artificially. In India, Farmers follow different irrigation systems to cultivate the crops.
