Research ArticleOpen accessIn the abstractSoil Erosion Prediction Based on Land Use Changes (A Case in Neka Watershed)Karim Solaimani, Saeid Modallaldoust, Sedigheh LotfiProblem statement: Land use change has transformed a vast part of the natural landscapes of the developing world for the last 50 years. Land is a fundamental factor of production and though much of the course of human history, it has been tightly coupled with economic growth. Soil erosion by water is one of the most important land degradation processes … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 2 · 30 Jun 2009 · 8,447 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimating the Scouring Depth of Bridge Pier Using Self-Organizing Neural Networks (SOM)Abolfazl Rafat, Gholam Abbas Barani, Amineh NaseriScouring is caused as a result of erosion of river bed by water flow and materials carried by water. This research estimates the scouring depth using self-organizing neural network (SOM). The obtained findings were compared with findings of other models. It was found that self- organizing neural network (SOM) has higher correlation coefficient (0.98), compared to other methods. It was … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 27 Nov 2017 · 7,500 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Some Organic Pollutants Transport into the Shallow Groundwater and Surface Water of Jiaxing Landfill AreaSouleymane Keita, Zhonghua Tang, Shaogang Dong, Yuehua JiangProblem statement: Hangjiahu regions belong to the Yangtze River Delta region in Zhejiang Province in China. The vast majority of this region is flat, so surface and groundwater both have a low flow rate. With the rapid economic development of the area, a large number of industrial and domestic garbage are generated. These landfill or garbage are exposed and stacked. … …American Journal of Applied Sciences, Vol. 6, Issue 12 · 31 Dec 2009 · 8,283 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Influence of Soil Characteristics in Low Flows RegionalizationPaolo Vezza, Claudio Comoglio, Alberto Viglione, Maurizio RossoProblem statement: For the purpose of low flows regionalization, relevant issue for water resources management like environmental flows requirements definition, this study focused on the controls on the seasonal and spatial variability of q95 (i.e., the specific discharge that was exceeded on 95% of all the time) with particular reference to the role of soil characteristics, that, like soil infiltration … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 6,480 accessesView PDFCite

Research ArticleOpen accessAll words, across the recordField Scale Modeling to Estimate Phosphorus and Sediment Load Reductions Using a Newly Developed Graphical User Interface for Soil and Water Assessment ToolAaron R. Mittelstet, Erin R. Daly, Daniel E. Storm et al.Streams throughout the North Canadian River watershed in northwest Oklahoma, USA have elevated levels of nutrients and sediment. Soil and Water Assessment Tool (SWAT) was used to identify areas that likely contributed disproportionate amounts of Phosphorus (P) and sediment to Lake Overholser, the receiving reservoir at the watershed outlet. These sites were then targeted by the Oklahoma Conservation Commission (OCC) … …American Journal of Environmental Sciences, Vol. 8, Issue 6 · 28 Dec 2012 · 6,470 accessesView PDFCite
