In order to systematically analyze the impacts of climate change and human activities on runoff, this paper takes Zhanghe River Basin, which is greatly affected by activities, as research object, constructs an attribution analysis model runoff changes based historical data SWAT (Soil Water Assessment Tool) model. The results show that watershed has significantly decreased in past 60 years, cont...
The flow rate of the Lower Jordan River has changed dramatically during the second half of the 20th century. The diversion of its major natural sources reduced its flow rate and led to drying events during the drought years of 2000 and 2001. Under these conditions of low flow rates, the potential influence of external sources on the river discharge and chemical composition became significant. O...
Deposition of sediment inside the conduit structures reduces the flow cross section area and increases the flow roughness which causes reduction of flow discharge passing through the conduit. Among the methods which can prevent sediment deposition is non sedimentation condition in the structure, Since the critical section of the inverted siphon in sedimentation is the outlet. In the begining of...
More than 131 x 10(6) metric tons (MT) of inorganic sediments accumulated in coastal wetlands when Hurricanes Katrina and Rita crossed the Louisiana coast in 2005, plus another 281 x 10(6) MT when accumulation was prorated for open water area. The annualized combined amount of inorganic sediments per hurricane equals (i) 12% of the Mississippi River's suspended load, (ii) 5.5 times the inorgani...
Abstract The People's Victory Canal Irrigation Area is a large gravity irrigation area in the middle and lower reaches of Yellow River. Groundwater hydrochemistry controlled by geochemical weathering, precipitation, from River diversion, artificial exploitation. Piper diagram, hierarchical cluster analysis, Gibbs ion proportion coefficient were applied to improve our understanding hydrogeochemi...
High salinity in water constitutes a serious problem for the aquatic environment management of Bosten Lake. Weak exchange and movement are essential factors high total dissolved solids (TDS) content lake water. To improve quality Lake, river–lake system connectivity project (water diversion) was introduced starting at end 2018, which diverted fresh from Kaidu River Huangshuigou to In this study...
#" !$" Snowmelt dominated streamflow of the Western Himalayan rivers is an important water !%" resource during the dry pre-monsoon months to meet the irrigation and hydropower needs !&" in northern India. This study is one of the first to look at the seasonal prediction of melt!'" dominated total inflow into the Bhakra Dam in northern India, based on statistical !(" relationships with meteorolo...
The Malnant River is a rapidly incising river with a French name that translates as ‘‘bad creek,’’ reflecting local opinion of the hazards from dramatic channel changes that have occurred in the last few centuries. Downcutting in the last three decades has created severe problems for farmers in this small watershed (16 km) as bridges are undermined, streamside roads are threatened, and irrigati...
–Sound management and protection of the Great Lakes Basin’s abundant freshwater resources requires the ability to predict local habitat conditions and fish communities across regional spatial scales. In response to concerns over increased use and potential diversion of its plentiful freshwater resources, the State of Michigan enacted legislation in 2006 that required creation of an integrated a...
