    sediment of floodplains which is contaminated by metals, was and still is set loose into the water flows. The rate of contamination can oscillate remarkably, due to the main dependency on the quantity of sediment which is affected by fluvial processes. The metals are furthermore able to reside in the floodplain for millennia, thereby having the possibility to have a serious effect on the environment, even long after sediment release. Researchers used several techniques, e.g. floodplain samples, to

    The Amazon Basin has long been occupied by indigenous populations. Those populations that live closest to the basin, in the lo west elevations, are subject to the extreme seasonal changes. Social order, therefore, is shaped largely by the fluctuations of the seasons and of the river. There are two seasons, one wet and one dry. Issues concerning shelter, transportation, food, and social interaction are largely determined by the seasons. Creative expression – mythology, religion, celebration, and visual

    Floods Focussing on the 2013 Minden, Ontario flood A flood is a large amount of water that covers an area that is normally dry. Floods can occur almost anywhere, but they happen more often on floodplains and on places close to the ocean. The land that floods regularly is called a floodplain. It is called coastal flooding when a large storm or wave from the ocean causes flooding in the cities inland. Some floods take days to develop, while others take minutes to form these are called flash floods

    1. To address water supply problem: 1) Water diversion and irrigation method A primary purpose of many dams, both large and small, is to facilitate water diversions. Although existing water supplies can be stretched much more and new water infrastructure can be deferred using water conservation and efficiency strategies described below, people will continue to divert water from rivers and other surface sources for various purposes. In many dam investigations, the question comes down to: could we

    Such complex requirements have become the main restriction for the existence of a highly adapted fish fauna in large rivers under regulated conditions. Unfortunately, in Europe, North America and northern Asia, 71% of large rivers and associated floodplains are affected by dams and dikes, their natural flow regime and connectivity having been altered (Burgess et al. 2012). The severe alterations of both hydrological regime and habitat diversity has induced subsequent changes of all biotic communities

    Since historical times populations that live within the urban and rural floodplains have learned of ways to adapt and survive (Balancing 2). With the economic development of many areas within the floodplain regions over the later part of the last century many areas have become further susceptible to seasonal rains and flooding. During seasons with heavier than usual monsoon rains the floodwaters which overwhelm the floodplains and drainage systems are flowing from the central regions of the country

    Introduction The topic of this literature review is restoration of the lower Colorado River Delta; the review will focus on pulse water flows as a method of restoration. Pulse flows are planned water releases from dams following years of water and sediment buildup behind dams. Hydrologist and advocates of pulse water releases believe that by adding water to a dry system, they can restore riparian areas by germinating native plants and providing habitat for endangered species. Furthermore, these

A geological study would show which areas are prone to getting sinkholes. • Floodplains Floodplains are low flat grounds around lakes, rivers and other water bodies which collect excess water from above the normal water levels on the bodies. Incase of heavy rainfall, these areas are at risk of being flooded. With the rapid expansion of cities, authorities have largely ignored the risk of floodplains. It is a matter of great concern that needs to be addressed. • Contamination sites There

    the floodplain reduces storage capacity and speeds up runoff sending more water to the river than the fields, which they replaced. Dams upstream trap sediment and speed up the flow downstream. Meander bends were straightened to improve navigability and speed flow. The river became 100 km shorter and 30% faster as a result. In addition upstream engineering narrowed the river floodplain, and two thousand islands were removed and the riverbed lowered by erosion. Due to this the floodplain storage

Inundation along some of the low-lying floodplains adjacent to major rivers can be both widespread and long in duration (Zillman 1999). In the case of the Ganges–Brahmaputra–Megna river system in Bangladesh, 110 million people are relatively unprotected on the floodplain of southern Asia’s most flood-prone river system (Smith 1996 pg 258).

Excessive rain, a ruptured dam or levee, rapid ice melting in the mountains, or even an unfortunately placed beaver dam can overwhelm a river and send it spreading over the adjacent land, called a floodplain. Coastal flooding occurs when a large storm or tsunami causes the sea to surge inland. Most floods take hours or even days to develop, giving residents ample time to prepare or evacuate. Others generate quickly and with little warning. These flash

    It’s funny that floods occur on land that is usually dry. They also occur in places close to rivers, streams, etc. Too much rain, fallen dams and many other ways can cause these rivers/streams to overflow and flood the land nearby, resulting in a floodplain. When a large storm or tsunami occurs, a flood is sure to follow. The danger of flood depends on whether they develop quickly or take time to develop. Flash floods are very dangerous as they come without warning resulting in a shortage of time for
