loess deposit is one of the most important quaternary deposits of northeastern parts of iran which have high erosion rate. this study was performed with field- rainfall- simulator which has a plot area of 1 m2 in gorganrood drainage basin to determine the effective factors on sediment yield. landuse, slope and erosion feature maps were overlaid in gis to obtain land unit map. then on work units...

Large-scale irrigation can alter the regional water cycle process, which changes structure and spatiotemporal distribution of local downwind precipitation, impacting soil erosion in both irrigated areas surrounding regions. However, effects large-scale on vulnerable have not been investigated. The study used high-resolution climate model (RegCM4) revised universal loss equation (RUSLE) to exami...

T h e Permo-Carboniferous sedimentary facies development in Thai land reflects the late V a r i s c a n orogeny in S E A s i a . During the Carboniferous and Permian, a N S trending trough separated the " S h a n T h a i C r a t o n " and the " Indosinia C r a t o n " . In this pelagic basin, deposition of ribbon cherts continued from pre-Asselian to Kubergandian. I n L o w e r Permian, carbona...

The shortage of drinkable water in many areas the world represents a fatal problem. desalination saltwater can be solution to this Solar still is simple and reliable system used arid sunny regions, but it has disadvantage relatively low productivity. A new configuration solar still, namely single slope double basin proposed current work increase prototype type was designed, fabricated, tested. ...

Using SeaBeam bathymetry and multichannel seismic reflection records we have identified three large submarine landslides on the southern Oregon Cascadia margin. The area enclosed by the three arcuate slide scarps is approximately 8000 km, and involves an estimated 12,000–16,000 km of the accretionary wedge. The three arcuate slump escarpments are nearly coincident with the continental shelf edg...

Groundwater, being a vital resource, needs to be developed with proper understanding about its occurrence in time and space. Unscientific sand mining is a dominant environmental issue in this humid tropical river basin namely Bharathapuzha river basin geographically on central part of Kerala state, southwest part of India. The sandy layers along the river course declines its water holding capac...

Although hypersaline environments pose challenges to life because of the low water content (water activity), many such habitats appear to support eukaryotic microbes. This contribution presents brief reviews of our current knowledge on eukaryotes of water-column haloclines and brines from Deep Hypersaline Anoxic Basins (DHABs) of the Eastern Mediterranean, as well as shallow-water hypersaline m...
