Rethinking the Filling Process of Mega‐Dam Cascades

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract The filling process of large hydropower reservoirs is an often‐overlooked process that can attract most of the attention and criticisms of a dam's lifetime. Understanding what drove past filling efforts and exploring trade‐off solutions is therefore critical for regions where hydropower development is flourishing.

Modeling Dissolved Organic Carbon Dynamics in an Alpine Catchment Incorporating the Mountain‐Front Recharge

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract The mountain front recharge (MFR) process significantly influences the movement of water and dissolved organic carbon (DOC) in alpine catchments. However, no existing watershed models can adequately simulate this process, hindering accurate quantification of streamflow and DOC dynamics.

Local and Landscape‐Level Environmental Conditions Drive Habitat Selection Across Terrestrial Mammal Species

Global Ecology and Biogeography, Volume 35, Issue 3, March 2026.
ABSTRACT Aim Animal movements are a fundamental process affecting communities and ecosystems. Quantifying habitat selection across species and habitats is key for understanding how animals respond to environmental change. Currently, we lack comparative studies that examine how habitat selection varies across species traits and landscapes.

Geospatial Analysis of Population Exposure to Flooding in the Sudd Region, South Sudan

Journal of Flood Risk Management, Volume 19, Issue 1, March 2026.
ABSTRACT The Sudd wetland in South Sudan extends over 90,000 km2. Large‐scale flood events in recent years (2019–2022) are said to have led to the displacement of an estimated 1.8 million people in total. However, these estimates are approximate and to date there has not been a systematic analysis of population exposure to flooding in the Sudd region ...

Flood Susceptibility Mapping and Climate Change Impact Prediction Using Probabilistic Machine Learning and Statistical Analysis: A Case Study of Kigali, Rwanda

Journal of Flood Risk Management, Volume 19, Issue 1, March 2026.
This study uses the MaxEnt model to identify key factors influencing flooding in Kigali, with slope being the most important. Future climate scenarios indicate that climate change could increase flood risk, highlighting the need for smart land use, better drainage, and green solutions to protect the city as it grows. ABSTRACT Flooding is among the most
