Application of hydraulic structures may control the destruction rate of the flood but sometimes they have undesirable effects on some aspects of flood behaviours leading to detrimental outcomes. In the present study, an attempt has been made to investigate the effects of bridges, culverts, groins and drops on inundation extension in a about 7 km long reach of Kan River, Iran.

Wetlands perform many essential ecosystem services—carbon storage, flood control, maintenance of biodiversity, fish production, and aquifer recharge, among others—services that have increasingly important global consequences. Like biodiversity hotspots and frontier forests, the world’s largest wetlands are now mapped and described by an international team of scientists, highlighting their conservation importance at the global scale. We explore current understanding of some ecosystem services wetlands provide.

In the Himalayan terrain, the Kosi river is formed by the confluence of seven smaller streams, viz. Indravati, Sun Kosi, Tama Kosi, Likhu Kosi, Dudh Kosi, Arun Kosi and Tamar Kosi at different places in China, Tibet and Nepal, before its entry into the Indian state of Bihar. The Kosi river is responsible for many floods in Bihar.

The Kosi river in north Bihar plains, eastern India presents a challenge in terms of long and recurring flood hazard. Despite a long history of flood control management in the basin for more than 5 decades, the river continues to bring a lot of misery through extensive flooding. This paper revisits the flooding problem in the Kosi river basin and presents an in-depth analysis of flood hydrology.

The Kosi afflux bundh breached in Kusaha in Nepal on 18 August 2008. This was the eighth incident of its kind and the first time did a breach occur upstream of the Kosi Barrage. The ones in 1968 and 1984 were no less disastrous but this year

The recent Kosi floods have proved once again that inadequate control measures have been responsible for the recurring disasters. Typically flood control and riverine studies focus on hydrological information, whereas a much more integrated approach that pays attention to specific morphological factors is required.
