surat is a highly developed, thickly populated cosmopolitan character city with full of various activities going on day and night. any natural calamity which causes loss of lives to property and infrastructure along with effects on industrial processes going on has serious impact on economy of the state. therefore, it becomes highly necessary that flood events are studied and analyzed properly ...
Simulation of floodplain zones in Tehran's metropolitan watershed (case study: Kaan basin) Ezaatollah Ghanavati, Associate prof. Geographical science faculty, Kharzmi University Ali Ahmmadabadi. Assistance prof. Geographical science faculty, Kharzmi University Negar Gholami, MA in Geomorphology, Geographical science faculty, Kharzmi University Extended abstract Floodplains and adjacent riv...
Arsenic contamination of groundwater in low-lying Bhagarathi–Ganga deltaic plain is known for more than two decades. The problem was recognized in 1984 (ref. 1) in West Bengal, when 16 patients from a village of 24 Parganas district reported arsenicosis. Subsequent investigations revealed extensive arsenic contamination in groundwater in the Bengal Basin affecting the eastern part of West Benga...
it is increasingly recognized that the land-use change, especially urbanization has influenced hydrological attributes intensely. but in most urban designs, flood prediction is considered through type of land use (residential, industrial, and so on) and density. however, experiences show that this method has not been very successful. as a result, the present study aims to investigate and explor...
IN T R O D U C T IO N Bridges are an integral part of any highway system. The design of a particular bridge depends on many variables. A major considera tion, often necessary, is the length of the bridge. In certain circum stances and locations the length may be dictated by factors other than cost. But, where necessary the designer must decide, “How far can the bridge approaches extend onto t...
Rivers are the natural flow of surface waters that flow in a certain bed seasonal or permanently. Rivers include a vast range of narrow waterways and with mountainous high steep to low steep and wide beds flowing in plains. However, rivers have had an effective role in urban development and human civilization, therefore, identification of flood prone areas and flood part in the potent lower fie...
Defining habitat suitability criteria (HSC) of aquatic biota can be a key component to environmental flow science. HSC can be developed through numerous methods; however, few studies have evaluated the consistency of HSC developed by different methodologies. We directly compared HSC for depth and velocity developed by the Delphi method (expert opinion) and by two primary literature meta-analyse...
Surface water that is the result of rainfall-runoff responses in a basin is a potential water source that if it is managed properly, can be useful to demand secure. Rain Water Harvestings an suitable option for monopoly and store runoff for future use, especially during the period that has restricted access to water. In this study has determined susceptible places for Rain Water Harvesting usin...
Organisms respond to cyclical environmental conditions by entraining their endogenous biological rhythms. Such physiological responses are expected to be substantial for species inhabiting arid environments which incur large variations in daily and seasonal ambient temperature (T(a)). We measured core body temperature (T(b)) daily rhythms of Cape ground squirrels Xerus inauris inhabiting an are...
The November 1996 jökulhlaup that burst from the Vatnajökull ice cap onto Skeiðarársandur was the highest-magnitude flood ever measured on the largest active glacial outwash plain (sandur). Centimeter-scale elevation transects, measured from repeat-pass airborne laser altimetry missions flown in 1996 (pre-flood), 1997, and 2001, show that sediment deposition exceeded erosion across the central ...
