Microclimf: Fast modelling of microclimate across real landscapes in R

Methods in Ecology and Evolution, Volume 17, Issue 4, Page 1112-1123, April 2026.
Abstract Many ecological studies require climate data, but readily available datasets are poor surrogates for the conditions that organisms experience in nature. Understanding the climatic conditions experienced by organisms requires modelling microclimate rather than relying on coarse, station‐based climate data.

Discharge Coefficients of Standard Spillways at High Altitudes

Designs
This paper presents an experimental campaign conducted next to the Condoroma dam, in Perú, at 4075 m a.s.l. The tests carried out in this paper were conducted in a 21 m long channel located at the toe of Condoroma dam.

Examination of Flow in a Chute Spillway During Flood Conditions Using a 3D Numerical Model

Journal of Flood Risk Management, Volume 18, Issue 4, December 2025.
ABSTRACT Dams are built for many purposes, one of the most important of which is to reduce the impact of floods. They release water downstream in a controlled manner through spillway structures. Spillways are critical structures that must be designed with low‐risk criteria to withstand floods that occur once every thousand years.

LWFBrook90.jl—Including Stable Water Isotopes in a Soil Vegetation Atmosphere Transport Model to Constrain Vertical Root Water Uptake Dynamics

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 11, November 2025.
Abstract In water‐limited ecosystems, soil water availability plays a pivotal role in determining the stress levels experienced by vegetation. Understanding the vertical distribution of roots and root water uptake (RWU) is essential for accurately predicting drought conditions using Soil Vegetation Atmosphere Transport (SVAT) models.

What Does the Triple Isotopic Composition of Oxygen in Precipitation, Groundwater, Soil Water, Plant Water, and Phytoliths Reveal About Current and Past Hydrological Cycles?

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 10, October 2025.
Abstract Quantitative data are needed to constrain the feedback loops between vegetation and hydroclimate. In this study, the amplitudes of variations in the triple oxygen isotope composition of water at the soil‐plant‐atmosphere interface are measured in savanna and dry forest contexts in West Africa (Benin and Senegal). Comparison of in situ data and
