Abstract
A serious constraint of data availability over flood-prone areas in India limits the potential of carrying out hydrodynamic flood modelling studies. Such difficulties are encountered because of a lack of high-resolution topography, cross-section data of the rivers, and sufficient and accurate calibration and validation data sets. The present study addresses the problems faced in performing a comprehensive 1D-2D coupled flood modelling over a flood disastrous region Jagatsinghpur, Odisha, India. The constraints faced in terms of hydraulic parameters such as water level, discharge, and geometric parameters such as river geometry are investigated. The simulations were performed for a severe flood event in 2011 that incurred heavy socio-economic losses in the district. The establishment of a modelling platform for flood simulation shall elucidate the major constraints faced in hydrodynamic modelling for such flood-prone areas with poor data availability.
期刊介绍：
The Journal will serve and provide a forum for exchange of ideas among business executives and academicians concerned with global business and economic issues. With the rapid evolution of corporate business from international to global in recent years, general business has been one of the areas of greatest added complexity and concern for corporate managers. It is no longer sufficient for the corporate manager to limit his/her study simply to the domestic aspects of general business. Almost every single topic that can be studied in general business now has global dimensions that are equally important. As such, practitioners and academicians, each with a unique perspective on global business, must go beyond the presently limited sharing of information and ideas. The Journal will be an academic journal combining academic inquiry and informed business practices. It will publish empirical, analytical, review, and survey articles, as well as case studies related to all areas of global business and economics. A sentiment often expressed by practitioners is that academic research in general may not be addressing the most relevant questions in the real world. To bridge some gaps in our knowledge of the real world, the Journal is thereby willing to sponsor a field research (such as surveys, in-depth interviews, on-site studies, etc.). It is fair to say that the Journal will publish high-quality applied-research papers. Nevertheless, studies that test important theoretical works and shed additional light on the issue with some business implications will also be solicited.
