Modeling of Non-Point Source Pollution by Long-Term Hydrologic Impact Assessment (L-THIA) (Case Study: Zayandehrood Watershed) in 2015‎

Background & Aims of the Study: In this research, Long-Term Hydrologic Impact Assessment model is selected for simulation of runoff and NPS pollution. The aim of this study is modeling of non-point source pollution by L-THIA model in Zayandehrood watershed in 2015. Materials & Methods: In this study, analytical survey and investigation of references in the context of libr...

Hypervelocity Impact on Rock

Concerted research efforts are being made to find new means of rock disintegration for more rapid, efficient excavation. Water jets, metallic jets and hypervelocity projectiles have been found to cut or break rock with varying degrees of efficiency depending upon several parameters, which are being defined by research in Russia, Britain and the United States. Optimum performance of high velocit...

Copper, Zinc, and Arsinic in Bottom Sediments of Clark Fork River Reservoirs: Preliminary Findings

Acetic acid extracts of sediments from four Clark Fork River reservoirs,--Milltown, Thompson Falls, Noxon Rapids, and Cabinet Gorge--indicate that mining and smelting operations in the upper drainage have enriched metal concentrations throughout the river. Milltown Reservoir contains metal values over 10 times the background levels for copper, zinc, and arsenic. Enrichment over background decre...
