River Restoration and Meanders
Among the most visually striking river restoration projects are those that involve the creation of a new channel, often in a new alignment and generally with a form and dimensions that are different from those of the preproject channel. These channel reconstruction projects often have the objective of creating a stable, single-thread, meandering channel, even on rivers that were not historicall...
متن کاملRiver restoration
[1] River restoration is at the forefront of applied hydrologic science. However, many river restoration projects are conducted with minimal scientific context. We propose two themes around which a research agenda to advance the scientific basis for river restoration can be built. First, because natural variability is an inherent feature of all river systems, we hypothesize that restoration of ...
متن کاملSustainability and River Restoration
One of the major problems causing the accelerating widespread destruction and degradation of the natural environment is the undervaluing of the protection and restoration of environmental resources that takes place in the decision making process. This paper argues that non-market values need to be incorporated in the benefit estimation process to make the concept of sustainability operational u...
متن کاملEstimators for anticipating river meanders: a comparative study
Increasingly, marine robots and unmanned surface vehicles will be deployed in rivers and riverine environments. The structure produced by flowing waters is worth investigating because it may be exploited for purposes of estimation, planning, and control. This report adopts a widely acknowledged model for the geometry of watercourse channels, namely sine-generated curves, as a basis for estimato...
متن کاملRecognizing Meanders to Reconstruct River Dynamics of the Ganges
The long-term discharge evolution of branches of rivers can potentially be derived from inactive and fossil river meanders using relations between discharge and channel width and meander dimensions. This evolution is relevant for the understanding of river dynamics and avulsion, and the resulting changes of downstream flooding risks and shipping conveyance. Unfortunately, digitalisation of infi...
