TL;DR: In this article, the authors present an assessment of climate change impacts on the hydrologic regime of the 600,000 km2 Upper Paraguay River basin, located in central South America based on predictions of 20 Atmospheric/Ocean General Circulation Models (AOGCMs).

TL;DR: In this article, an improved version of the COTAT algorithm was proposed to reproduce actual drainage networks more closely when applied in regions with meandering rivers running in parallel and for cell sizes of the order of 10 kilometers.

TL;DR: This work presents the development of a water quality model coupled with GIS for representing impacts of point-sourced pollutants released with distinct durations under different flow scenarios, allowing a systemic view of the entire basin, and capable of being used with low data availability.

TL;DR: In this article, the authors investigated the potential of SWOT to correct hydrological models on a global/continental scale, through data assimilation, using an Observing System Simulation Experiment (OSSE) also known as “twin experiment”.

TL;DR: The IPH-Hydro Tools is presented, an open source tool coupled to MapWindow GIS software designed for watershed topology acquisition, including preprocessing steps in hydrological models such as MGB-IPH, allowing for better drainage network and less processing time for catchment delineation.
