Trends, challenges and opportunities of flood warning systems in India
http://www.inderscience.com/link.php?id=136029
Floods are one of the most recurrent natural disasters that affect many states in India. Due to the varied nature of its climatic conditions and diverse topographical features, different parts of India receive precipitation in differential amounts, intensity and period. In India, flood warning agencies at the central level, design flood forecasts for the entire country utilising capabilities based on the hydrological modelling approach. Based on forecasts, they release flood warnings and notify the central government through its different departments and stakeholders to undertake mitigating measures in advance. This paper attempts to highlight the currently prevalent flood forecasting practices in releasing flood warnings to the population at risk in different parts of India. Further, flood warning approaches employed on national, state and local level have also been discussed. Based on the reviews, challenges and opportunities associated with existing flood warning systems in India are outlined.

Hydrological model performances in small and mid-size Brazilian semi-arid ungauged watersheds under agricultural use
http://www.inderscience.com/link.php?id=136032
Hydrological applications in ungauged watersheds, typical in the Brazilian semiarid environment, require knowledge of hydrological response. To compute the runoff from these watersheds, conceptual models are often employed. This study evaluated the performance of four conceptual models, and the probability density functions (PDFs) that best fit the hydrometric data were determined. All semiarid watersheds under semiarid crops showed runoff coefficients from 0.49 to 0.56 for all return periods, implying that about 50% of rainfall became runoff, so the soil tillage used in these semiarid crops was inadequate and degraded the soil and the Brazilian semiarid. The Gamma and log-normal PDFs showed the best agreements with observed streamflow data from the Exu, Jacu, and Cachoeira watersheds. The efficiency indicators showed that the performance of hydrological models applied to these Brazilian semiarid ungauged watersheds was linked to the watershed size and the time of concentration.

Cooperation over the Nile basin water management and the permanent risk of conflicts
http://www.inderscience.com/link.php?id=136042
The Nile basin states are reluctant to undertake serious cooperation between them. All through the history, the agreements over the use of the Nile waters have been partial biding some of the riparian countries. All the attempts to set an inclusive treat like the Cooperative Framework Agreement in the Nile Basin came to fail maintaining a status quo to the benefit of Egypt. However, new trends are drawing a new configuration of the social, ecological, diplomatic and political context in the region causing the upstream states to contest this status quo. The construction and the exploitation of the Great Ethiopian Renaissance Dam shows how this region of Africa is subject to a permanent risk of armed conflict due to lack of collaborative use of the water resources of the Nile Basin. The research methodology used in this paper has been the desk study approach combining analysis of well renowned authors' writings and jurisprudence.

Exploring the nexus of freshwater resources and international conflict: bibliometric insights and a research agenda for the future
http://www.inderscience.com/link.php?id=136043
Accessing and controlling freshwater resources holds immense significance in ensuring human survival, preserving ecosystems, and fostering economic growth. The confluence of water scarcity and heightened demand has precipitated disputes that have further exacerbated global conflicts. Despite the growing research efforts in this area, a comprehensive literature review on freshwater resource and international conflict is lacking. This study employs a comprehensive bibliometric analysis to examine the interplay between scientific research on freshwater resources and international conflicts. A two-tier approach is adopted, analysing 779 papers from the Scopus database. In the first tier, advanced bibliometric techniques are utilised to track the evolution and current state of the literature, identifying specific research clusters. The second tier involves a detailed content analysis of these clusters, providing insights for future research directions. The findings present valuable insights for researchers seeking to understand the complex relationship between water resources and global conflicts.
