Long-Term Assessment of Nitrogen Pollution Load Potential for Groundwater by Mass Balance Analysis in the Tedori River Alluvial Fan Area, Japan
To evaluate the nitrogen pollution load in an aquifer, a water and nitrogen balance analysis was conducted over a thirty-five year period at five yearly intervals. First, we established a two-horizon model comprising a channel/soil horizon, and an aquifer horizon, with exchange of water between the aquifer and river. The nitrogen balance was estimated from the product of nitrogen concentration ...
متن کاملAnalysis of Flood Hydraulic in Alluvial Fan River using CCHE2D Case Study: (Roodan River)
In this study the advantages and importance of a numerical model to predict and monitor the processes governing hydraulic changes alluvial fan river is discussed. For this reason and because of the importance of flow velocity and shear stresses resulting from the erosion of the river, A two-dimensional numerical model to simulate the CCHE2D river changes ranging from Roodan River is used. In th...
متن کاملOccurrence of arsenic in ground water in the Choushui River alluvial fan, Taiwan.
An investigation of shallow ground water quality revealed that high arsenic (As) concentrations were found in both aquifers and aquitards in the southern Choushui River alluvial fan of Taiwan. A total of 655 geological core samples from 13 drilling wells were collected and analyzed. High As contents were found primarily in aquitards, to a maximum of 590 mg/kg. The contents were correlated with ...
متن کاملHigh Recharge Areas in the Choushui River Alluvial Fan (Taiwan) Assessed from Recharge Potential Analysis and Average Storage Variation Indexes
High recharge areas significantly influence the groundwater quality and quantity in regional groundwater systems. Many studies have applied recharge potential analysis (RPA) to estimate groundwater recharge potential (GRP) and have delineated high recharge areas based on the estimated GRP. However, most of these studies define the RPA parameters with supposition, and this represents a major sou...
