This paper illustrates how archaeomagnetic dating can be used for palaeochannel fills within floodplain sequences. The sites investigated are palaeochannels associated with the mediaeval braided/anastomosing channels of an unstable reach of the River Trent at Hemington, north-west Leicestershire. This reach has revealed abundant archaeological remains including fish weirs, anchor stones, a Norm...

Alluvial placer gold deposits that accumulate in streams across the globe are essentially allochthonous sedimentary transported from their source to location of deposition. The purpose this study was find alluvial sediments along Indus River NW Himalaya Pakistan. investigated region divided into five clusters based on river morphology. research focused mineralogical distribution, sediment sourc...

We describe the first detailed reach-scale study of an incisional till-bed river. Our analysis focusses on boundary till characteristics, bare patch features, annual erosion rates, bedform dimensions and spacing, grain size distributions bedforms. Results show that exposures constitute a relatively small portion bed rates are high compared to bedrock rivers, although highly variable between pat...

some macroinvertebrate indices of stream health have been identified as most useful and efficacious. management decisions can be made with greater awareness.the objectives of this study were to assess the biological water of the hazar river using macroinvertebrates.the haraz river is one of the best freshwater ecosystems in the mazandaran province located in the north of iran.to assess the macr...

The challenge of a depleting Mississippi River Valley Alluvial Aquifer (MRVAA) requires reducing groundwater withdrawal for irrigation, increasing aquifer recharge, and protecting water quality sustainable use. To meet the challenge, National Center Research (NCAAR) is oriented towards producing scientific work aimed at improving irrigation methods scheduling, employing alternative sources, cro...

introduction interaction between internal and external processes of the earth during time plays an important role in formation and landforms transformation. we can identify course of their process changes with landform survey. in the middle parts of iran, there are several geomorphologic evidence of arid and rainy climate changes. playaes and lakes or generally internal holes had an important r...
