Weirs are often constructed on mountainous rivers because of their low construction costs and ability to provide irrigation facilitate landscaping, yet there is little research how fish habitat quality in responds weir distribution. This study categorized the distribution characteristics weirs typical reaches according sinuosity calculated corresponding suitability index (HSI) weighted usable a...

An assessment of the meandering stream type using its classification system to geomorphology characteristics combined with GIS-based analysis is presented in this paper. It describes consisting 8 parameters that differ zone sediment position, width, sinuosity, amplitude, wavelength, bend sharpness, meander pattern, and slope. The selected case study paper Barito Stream, South Kalimantan, Indone...

Ungulate vehicle collisions (UVC) provoke serious damage, including human casualties, and a large number of measures have been developed around the world to avoid collisions. We analyse the main factors involved in UVC in a road network built in the absence of ungulates, where mitigation structures to avoid UVC were not adequately considered. Ungulate population greatly increased during the las...

Over the 150 year history of major agricultural activity in Iowa nearly all the native prairie (99.9%) and wetlands (95%) were lost as native plant communities were converted to row-crop agriculture. This major change from perennial to annual upland vegetation was accompanied by broad scale installation of tile drainage intended to remove moisture from saturated wetland soils, increasing availa...

current research in order to identify neo tectonic activity of the ziyarat basin has been made on the northern slopes of the eastern alborz in south-gorgan and using the index of morpho tectonic and tectonic evidence in the area. in this regard, the 6 morphological parameters were calculated and the results are analyzed. the overall results of these features, as indicators of the relative activ...

Article history: Received 7 August 2015 Received in revised form 21 January 2016 Accepted 22 January 2016 Available online 23 January 2016 In order to better understand the activity of the Akşehir normal fault in SW Turkey and the associated seismic hazard, we investigated the tectonic geomorphology of a 60-km stretch of the 100-km-long Akşehir fault block. The fault can be separated into seven...

The morphological changes in the river channel over periods that occur due to flood events, affected sinuosity index of channel. characteristic like also determines intensity a Recent losses have increased as result variability rainfall; simultaneously such problems are coming up with sustainable development. attempted research study has been carried out evaluate and understand bank stability M...

Analysis of 41 ERS 1 synthetic aperture radar images and simultaneous ground measurements of discharge for three large braided rivers indicates that the area of active flow on braided river floodplains is primarily a function of discharge. A power law correlation is found between satellite-derived effective width We and discharge Q, where We is the water surface area within a braided reach divi...
