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 ...

Influence des élevages extensifs en étang sur les rivièrese [PDF]
, 1991 Si de nombreux travaux ont porté sur l'influence des piscicultures intensives sur les rivières, on s'est peu intéressé aux conséquences des nombreuses créations de plan d'eau sur le milieu.

Global Change Biology, Volume 31, Issue 7, July 2025.Severe drought increasingly threatens the resilience of forest biomes worldwide. Using a tree‐ring database from Canadian forests, encompassing 40,147 trees across 4558 plots and 23 species, we analyzed temporal and spatial patterns of drought resilience.

La rivière sous le regard de l'écologue
Sciences, Eaux & Territoires, 1997 Aujourd'hui, la dimension scientifique de la connaissance des cours d'eau français est insuffisante. Les recherches se cantonnent en général aux fleuves Rhin-Rhône-Loire-Garonne, etc., mais globalement, l'ensemble des cours d'eau de moyenne importance et

Les cours d'eau de Nouvelle-Zélande
Revue de géographie alpine, 1979 Abstract. — Precipitations fall in high quantities upon the New- Zealand Alps (South Island), from 7 to 9 meters a year, 25 % of which are represented by snow. Notwithstanding mild temperatures, they give rise to many glaciers; but the run-off pattern of their emissaries is dominated by rain. Ice melt contributes about 10 %, snow melt 10 % and rain 80 %

Minimum leaf conductance during drought: unravelling its variability and impact on plant survival
New Phytologist, Volume 246, Issue 3, Page 1001-1014, May 2025.Summary Leaf water loss after stomatal closure is key to understanding the effects of prolonged drought on vegetation. It is therefore important to accurately quantify such water losses to improve physiology‐based models of drought‐induced plant mortality.
