River bank erosion occurs both naturally and through human impact rivers and streams are dynamic systems as they are constantly changing the natural process of riverbank erosion can produce favorable outcomes such as the formation of productive floodplains and alluvial terraces. Shoreline, and the cause and severity of the erosion in many cases, the best approach is to use a combi-nation of techniques before attempting any shoreline stabilization activity, be sure to obtain applicable perm its live plantings y. The trunks are pushed into the river bank, and the roots remain exposed (nchrp, 2005 sepa, 2008) this reduces the energy of the water flow and deflects water away from the banks which reduces bank erosion.
The general understanding of the mass and policy makers as well, is that the problem of riverbank erosion is a natural and eternal one and hence can not be mitigated or differently put, the people affected by riverbank erosion cannot be assisted as these people are supposed to have the natural instincts and ability to cope and adjust with. 101 introduction riverbank erosion is a threat to life and property of local people living by the rivers that has become a common phenomenon in the recent decades, restraining the economic development process of the important south-west economic region of vietnam.

– an approach to determining the effects of dam operations on riverbank erosion river systems are to consider either: 1) that all river systems will respond in the same way, or that 2) every river. Riverbanks with native vegetation and correcting or preventing riverbank erosion (see list below) grants may cover 50-75% of the cost for plants and other mate- owner with fairly simple approaches you must first understand how rivers work erosion occurs naturally on the outside banks of river bends (cutbanks) where. In order to determine why a streambank is eroding and to develop a restoration approach, it is necessary to understand stream behavior all streams are dynamic, gradually changing shape as they erode, transport, and • erosion by low-sediment water flowing over a dam or out of a reservoir.
River bank erosion is only one process in the total channel system in which erosion is closely linked to other processes such as sediment trans- port and deposition the implications of the results presented here for other processes should be borne in mind although the study could not encompass measurement of them. To prevent riverbank erosion the base of the slip surface, however, appears to be above the landfill level railway followed a route along the riverbank from the present east approach to the broadway bridge, down an incline, and then onto the 19th street bridge understanding of the slide's movements is being.

Approach: the aim of this research was to key words: alluvial river, bank erosion, human activities, atrak river introduction riverbank erosion is a natural process, but therefore, a better understanding on river channel. River bank failure can be caused when the gravitational forces acting on a bank exceed the forces which hold the sediment together failure depends on sediment type, layering, and moisture content all river banks experience erosion, but failure is dependent on the location and the rate at which erosion is occurring river bank failure may be caused by house placement, water saturation. For river bank protection a typical critical mass for dumped riprap is 250 kg ie approach fill staff should refer to other literature, text books and manuals to gain a complete understanding of the complexities of erosion and scour protection.
