We huddled together on the bank of the river in the cool spring night, drinking tea and warming our hands at the fire. The full moon shone intermittently through the clouds, illuminating the river below. Suddenly from downstream came the cry "Flood-O!" We ran higher up the bank with a low, rumbling sound in our ears. As we reached the top of the bank a wall of water four feet high passed be­ lo...

In China, the Lower Jingjiang Reach (LJR) of the Yangtze River could be one of the most complicated areas in terms of channel migration. The river had undergone many channel changes in the reach since the 18th century. Intensive human activities in recent decades, such as the construction of upstream dams and revetments, had directly affected the channel migration characteristics. The revetment...

Extended abstract 1- Introduction Rivers are one of the dynamic landforms of natural landscapes that are subject to changes due to environmental variables and human interactions during different times and locations. Changes in the river, erosion of the bed and river bank are natural processes of alluvial rivers that destroy the surrounding agricultural land and damage human installations arou...

Bank filtration of river or lake water represents an efficient and natural purification process used for the drinking water production in many countries and at an amount of about 15-16% in Germany. From experiences over decades particularly at the river Rhine and Elbe, it is known that the occurrence of persistent pollutants in river water can represent a problem for the quality of drinking wat...

One surviving stronghold of endangered Northern swamp deer is Jhadi taal (lake) in Kishanpur Wildlife Sanctuary on the floodplains of Sharda River. Changes in channel characteristics and land use/cover in a stretch of the river were detected during 1948–2001 and their impact on deer habitat was assessed. Analyses revealed consistent shift of west bank line towards taal, moving to within 100 m i...

An excessive amount of bank erosion along a number of waterways in Illinois and surrounding states exists at the present time. Erosion of stream banks attracts public attention, reduces property values, results in the permanent loss of real estate, increases the turbidity of streams, and accelerates the silting of reservoirs and backwater lakes along stream courses. Among the main causes of ban...

Rivers have a complicated and various condition in the diverse environment, and various science such as Hydrology, geomorphology, hydraulic, ecology and engineering have it been discussed. River geomorphology with studying of river process and landforms, examination of river landscape evolution, can be playing an important role in identifying of river channel character and behavior. To order th...

چکیده: سیلاب فاجعه بارترین حادثه طبیعی در کره خاکی ماست. این حادثه طبیعی را میِِ توان از دو دیدگاه مهار و مدیریت سیلاب بررسی کرد.مدیریت مقوله ای فراتر از مهار وکنترل سیلاب می باشد. با توجه به تجربیات جهانی مهار کامل سیلاب امری غیر ممکن است، وباید در مدیریت سیلاب سرمایه گذاری کرد. مدیریت غیر سازه ای بخشی از مدیریت سیلاب است که در آن برای مقابله با سیلاب سازه ای احداث نمی شود. از جمله بخش های مدیر...

A method has been developed which automatically extracts river and river bank locations from arbitrarily sourced high resolution ("lm) visual spectrum imagery without recourse to multi-spectral or even color information. This method relies on quantifying the difference in image texture between the relatively smooth surface of the river water and the rougher surface of the vegetated land or buil...
