From Indicator to Prediction: Five Decades of Biochemical Oxygen Demand Research in Tropical Freshwaters

World Water Policy, Volume 12, Issue 4, November 2026.
ABSTRACT Biochemical oxygen demand (BOD) remains a core indicator of organic pollution in freshwater monitoring, but its role in water policy and practice is changing as water‐quality assessment moves toward predictive, integrative, and decision‐support approaches.

Arcabouço de modelo hidrológico de escala continental utilizando-se a topologia da rede de drenagem simulada: aplicação na bacia hidrográfica amazônica

Geografia (Londrina), 2010
Os processos representados em um modelo hidrológico podem ser divididos em movimentação vertical e horizontal da água. A maioria das representações integradas entre modelos atmosféricos e hidrológicos considera apenas a movimentação vertical e/ou ...

From Crisis to Resilience: Rethinking Urban Flooding and Groundwater Recharge in Bengaluru City, India

World Water Policy, Volume 12, Issue 3, August 2026.
ABSTRACT Bengaluru, a primary metropolitan centre in India, is currently grappling with the dual crises of urban flooding and severe groundwater depletion. These challenges are driven by rapid urbanization, which has seen built‐up areas increase from 42% to 86% over two decades, resulting in a dramatic loss of vegetation and wetlands.

Stemflow Dynamics in the Jamari National Forest (Brazilian Amazon): I. The Role of Tree Structure

Biotropica, Volume 58, Issue 3, May 2026.
A portion of rainfall that contacts tree canopies is drained down tree stems as stemflow. Stemflow is an underexamined component of rainfall partitioning in tropical forests. To investigate how tree canopy structural attributes influence stemflow in the Brazilian Amazon, we measured stemflow, rainfall, and dendrometric parameters of 56 trees in the ...

How Spatial Resolutions Impact the Large‐Scale River Hydrodynamic Model Simulations: Analysis Focuses on Model Physics

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 11, November 2025.
Abstract Large‐scale hydrodynamic models are vital for flood risk assessment and understanding the global water cycle; however, their results can include uncertainties related to spatial resolution. Few studies have evaluated hydrodynamic models across a range of spatial resolutions, with most focusing on a few variables (e.g., discharge) and often ...

Satellite Requirements to Capture Water Propagation in Earth's Rivers

Reviews of Geophysics, Volume 63, Issue 3, September 2025.
Abstract The water in Earth's rivers propagates as waves through space and time across hydrographic networks. A detailed understanding of river dynamics globally is essential for achieving accurate knowledge of surface water storage and fluxes to support water resources management and water‐related disaster forecasting and mitigation.
