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.

FLOWS, MORPHOLOGY AND VEGETATION INTERACTION, A CASE OF THE HYDROPOWER DOMINATED MIDDLE ZAMBEZI CATCHMENT
Author : ELENESTINA MWELWA-MUTEKENYA1, CROSATO ALESSANDRA2, KHAN OMAR3, WRIGHT NIGEL4
From the rich biodiversity that the Middle Zambezi sub-catchment supports, both Zambia and Zimbabwe have established National Parks, with Mana Pools National Park, Sapi and Chewore safari areas being designated as UNESCO World Heritage Site in 1984 (UNESCO World Heritage Centre 1992-2013). The habitat sustenance depends on the river channels and the associated morphological features with the flood and recession interactions, whose modification can lead to negative environmental consequences. The research work in the area has the key objective to investigate the state of the river and its flood plain environment in terms of surface and ground water flow and morphological variation, for both the pre and post hydropower situations, and the associated impacts on the floodplain tree species the Faidherbia albida. This tree is of vital importance for the local wild life, since its leaves and fruits constitute an important food source during the dry season. In the last decades, however, the tree has shown a worrying decrease in its germination rates, so that young trees can only be found on the river islands, whereas the river banks host deteriorating old trees. To identify the cause of floodplain vegetation degradation, this research work spanned the fields of engineering, hydrology, geomorphology and ecological/environmental science.
