Estimation de l’Influence d’Occupation du Sol sur les Paramètres Hydrologiques de la Zone à Tourbière du Bassin versant de La Rivière Itimbiri dans la Partie Nord -Est du Bassin Du Congo

open access: yesRevue Congolaise des Sciences et Technologies
Cette étude vise à établir un modèle hydrologique pour le bassin versant de la rivière Itimbiri afin d'évaluer les ressources en eau disponibles et d'appuyer la prise de décision pour une gestion efficace et durable de ces ressources.

Spatial Patterns and Controlling Factors of River Flow Intermittency in Africa

open access: yesWater Resources Research, Volume 62, Issue 6, June 2026.
Abstract Understanding river flow intermittency remains a major challenge in data‐scarce regions such as Africa. This study presents the first high‐resolution, four‐class intermittency map of African rivers using a sequential modeling approach based on Random Forest. A binary model (BC‐UNS) distinguishes perennial from non‐perennial reaches across 15.5

Development and Testing of a Low‐Cost Soil Moisture Sensor for Real‐Time Irrigation Scheduling

open access: yesIrrigation and Drainage, Volume 75, Issue 1, Page 173-187, February 2026.
ABSTRACT Effective irrigation scheduling is essential for improved water management in irrigated areas, with soil moisture monitoring recognized as one of the most effective methods. However, challenges such as the high cost of sensors and the difficulties in monitoring large areas hinder their practical application, particularly for smallholder ...

Behavioural tactics across thermal gradients align with partial morphological divergence in brook charr

open access: yesJournal of Animal Ecology, Volume 95, Issue 2, Page 359-376, February 2026.
Our study reveals that brook charr adopt distinct ‘warm’ and ‘cool’ behavioural tactics to balance foraging and thermal stress in stratified lakes. By linking fine‐scale thermal movements to morphology, we show how temperature‐driven habitat use promotes individual specialization and potential ecotypic divergence under climate change.

Conception of a synthesis pozzolan from sediment dams calcined (Case: Gargar dams)

open access: yesMATEC Web of Conferences, 2014
Silting of dams is undoubtedly the most dramatic consequence of the erosion problem in Algeria. In spite of the great ways implemented for the construction of retaining structures, the storage of water remains confronted with the difficulties of their ...

The morphosedimentary record of glacial to postglacial environmental changes in West Wiyâshâkimî impact crater lake and adjacent areas, northern Québec, Canada

open access: yesBoreas, Volume 55, Issue 1, Page 110-133, January 2026.
Crater lakes in core regions of former ice sheets have the potential to preserve long‐term sedimentary archives that are otherwise rare in glaciated landscapes due to pervasive glacial erosion. Lake Wiyâshâkimî, an impact crater lake located in the inner core of the Québec‐Labrador Dome of the Laurentide Ice Sheet, provides a rare example of such a ...

Assessment of Constraints, Opportunities and Income Impacts Associated with Small‐Scale Irrigation in Zebit, Ethiopia

open access: yesIrrigation and Drainage, Volume 74, Issue 5, Page 2174-2184, December 2025.
ABSTRACT Small‐scale irrigation represents a highly effective system designed to enhance production and productivity, mitigate risks associated with rainfall variability and increase the income of rural farm households. This study was conducted to analyse small‐scale irrigation impact on household income and assess the challenges and opportunities in ...
