A Copula‐Based Regression Method to Predict Sediment Concentration and Load in Rivers Using Streamflow Data

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract Pollution and deposition of sediments in rivers and streams are critical environmental, ecological, navigational, and recreational concerns. While several well‐known watershed models such as SWAT (Soil and Water Assessment Tool) and HSPF (Hydrological Simulation Program‐FORTRAN) are applied to predict sediment concentrations and loads in ...

Porous and Permeable Crystalline Basement: Evidence for Large‐Scale Hydraulic Connectivity at Kivetty, Finland

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Porosity and permeability in crystalline shield basement are commonly assumed to be low, yet some fault zones sustain fluid circulation over kilometer scales. Here we quantify multiscale fault‐zone connectivity at Kivetty, central Finland, by integrating legacy deep‐borehole data, including packer tests, downhole logs, and a long‐term multi ...

When There's No November Rain: Developing a Parametric Insurance for Hydroelectric Energy Generators in Brazil

Risk Analysis, Volume 46, Issue 9, September 2026.
ABSTRACT Hydrological risk is a growing challenge for renewable power systems, as droughts reduce generation, increase costs, and expose gaps in risk‐transfer mechanisms. We examine this problem in Brazil, home to the world's sixth‐largest electricity system and highly dependent on hydroelectricity, which accounted for 43% of installed generation ...

A higher rank shifted convolution problem with applications to L$L$‐functions

Proceedings of the London Mathematical Society, Volume 133, Issue 3, September 2026.
Abstract While several instances of shifted convolution problems for GL(3)×GL(2)${\rm GL}(3) \times {\rm GL}(2)$ have been solved, the case where one factor is the classical divisor function and one factor is a GL(3)${\rm GL}(3)$ Fourier coefficient has remained open. We solve this case in the present paper.
