Organic pollution of rivers by wastewater discharge from human activities negatively impacts people and ecosystems. Without treatment, pollution control relies on a combination of natural degradation and dilution by natural runoff to reduce downstream effects. We quantify here for the first time the global sanitation crisis through its impact on organic river pollution from the threats of (1) i...

Introduction The Nile River the longest river in the world has been serving as a source of life to the people living in its basin for centuries. Throughout the course of history, the Nile has supported livelihoods and played a considerable role in enriching diverse cultures within its basin. Hence, the Nile has been the centre of attention of explorers, tourists, researchers and historians for ...

abstract many researchers have recently considered the use of data obtained from remote sensing (r.s) to reveal changes. in the present study, we have attempted to reveal the morphodynamic changes in taleghan river basin through image satellite and by analyzing the principal component analysis (pca) and fuzzy logic. the final map indicates the intensity of changes through, 15-years interval obs...

Accurate terrain models are a crucial component of studies of river channel evolution. In this paper we describe a new methodology for creating high-resolution seamless digital terrain models (DTM) of river channels and their floodplains. We combine mobile laser scanning and low-altitude unmanned aerial vehicle (UAV) photography-based methods for creating both a digital bathymetric model of the...

Significant advances have been made towards understanding the dynamics of geomorphic systems through the development of new concepts. In the last two decades, these developments were partly guided by the change in the scale of geomorphic analysis from local (landform) to regional (landscape) scale and partly due to the emergence of new scientific tools and quantitative models. The process-based...

Introduction Sea level rise, especially combined with possible changes in storm surges and increased river discharge resulting from climate change, poses a major threat for a low-lying delta like the Netherlands. Future flood protection strategies need to take these possible changes into account. Therefore, high-impact, low-probability climate change scenarios for the Netherlands were developed...
