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 …
The greater Himalayan region and its water resources play an important role in global atmospheric circulation, biodiversity, etc while serving more than 1.3 billion people in the basin areas of ten large Asian rivers. This paper discusses these issues, the need to close the knowledge gap, the need for adaptation …
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 …

Statistical factor analysis (FA) technique has been applied to chemical data of 125 bore well water samples from Kumadvathi river sub-basin to assess the un-usefulness of such techniques for interpretation of the hydro-chemical data. FA technique identified three factors, which account for 60% of the major ion variations observed in …
Emphasis has been laid since long on the need for integrated catchment management and impactof landuse on catchment hydrology; but the two disciplines have not been amalgmated for creating catchment sensitive 'City Landuse plans'. This study aims at (a) utilizing hydrological modeling to understand the dynamics of an urban Himalayan …
Many rivers in India are shared resources, flowing through or between more than one province and more than one country. The combined effect of climatic stochasticity, rapid population growth and inefficient water infrastructure is increasing stress on river basin ecosystems.
Geological records point out to a period of aridity 10,000 years ago, at the end stage of Pleistocene glaciation, which gradually changed to a wet phase. Copious rainfall in the Himalayan region gave rise to innumerable rivers, mainly Saraswati river along with six other rivers which flowed down in cascades …
Mosul dam is one of the biggest hydraulic structures in Iraq. It is located on Tigris River north Iraq and was selected as a case study to predict flood disasters caused by a hypothetical Mosul dam failure due to its foundation defect in which the dam had been survive since …
New method takes into account turbulence in flow of water ABOUT a hundred thousand farmers in Malda and Murshidabad districts of West Bengal lose land and homes to erosion caused by the Ganga every year. With little knowhow on when the river will wash away their farmland, they are compelled …
This book is all about water. It is authored by academics, some of whom can write in a way lay people can understand. Importantly, all the essays are profusely referenced, so someone wanting to read further knows where to look. It begins with a chapter by Ramaswamy R Iyer, an …

Crossing through ten countries and draining the territory of 19 countries, the Danube is the most international river in the world. In addition to the 83 million people living in the river basin, the Danube is home to globally important species of flora and fauna.
The most important practical and critical problem related to the performance of reservoirs is the estimation of storage capacity loss due to sedimentation process. The problem to be addressed is to estimate the rate of sediment deposition and the period of time at which the sediment would interfere with the …
The study area is a part of Kagna river basin in the Gulburga district of Karnataka, India. Remote sensing and GIS techniques have proved to be efficient tools in drainage delineation and their updation. These updated drainages have been used for the morphometric analysis. The morphometric analysis was carried out …
