IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Experimental and Numerical Study on Hydrodynamics of Riparian Vegetation
Author : Takuya Uotani, Keiichi Kanda and Kohji Michioku
Recently, many river channels in Japan tend to be heavily vegetated due to regime shifts in hydrological, fluvial and ecological processes. Dense vegetation on floodplains and sandbars frequently obstructs a flood flow and reduces channels' conveyance capacity. On the other hand, it is important from an environmental viewpoint to make a proper management of riverine vegetation, because trees and plants provide habitats for various species and life. They play an important role as a part of the river ecosystem. In order to preserve trees nature and keep a certain level of flow conveyance capacity, thinning and felling of riverine trees might be one of possible management strategies for a sustainable and economically feasible river management. In order to investigate effects o f tree thinning on river hydrodynamics, a laboratory model experiments was carried out in a compound open channel with riparian vegetation, which is a typical ecological structure frequently observed in many rivers. Hydrodynamics were experimentally and analytically investigated under various vegetation and hydraulic conditions.
