Transmission Water Losses at South African Irrigation Schemes: A Case Study of the Vaalharts Irrigation Scheme

Irrigation and Drainage, Volume 74, Issue 4, Page 1818-1829, October 2025.
ABSTRACT Irrigation water supply is under scrutiny because of dwindling water resources. Most irrigation water in South Africa (SA) is transmitted by canals. Transmission water loss (TWL) accounts for 12% of the irrigation water losses in SA. Therefore, there is a need to investigate and understand the major parameters influencing TWL at Vaalharts ...

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

Projected Climate Change Impacts on Groundwater–Surface Water Connectivity in a Compartmentalized Mountain Headwater Bedrock Aquifer

Water Resources Research, Volume 61, Issue 10, October 2025.
Abstract How mountain headwaters and their groundwater‐dependent ecosystems will respond to future climate change remains largely unknown. These challenges stem from the difficulty of gathering relevant hydrological observations and implementing modeling strategies suited to data‐scarce systems.
