A new method of estimating infiltration parameters for furrow irrigation

Irrigation and Drainage, Volume 74, Issue 2, Page 658-672, April 2025.
Abstract In this study, we present new two‐point and one‐point methods for estimating infiltration parameters in furrow irrigation. It is assumed that infiltration and waterfront advance along the furrow follow the Valiantzas two‐parameter infiltration and power advance equations, respectively.

An assessment of future climatic and anthropogenic impacts on the hydrological system of a semi‐arid catchment

Irrigation and Drainage, Volume 74, Issue 2, Page 834-860, April 2025.
Abstract Climate and catchment characteristics, particularly land and water use and management, may vary according to the population growth rate, future food habits and water demands. Three climate simulations corresponding to the Intergovernmental Panel on Climate Change, Special Report on Emissions Scenarios (A1B) were downscaled using the ‘Providing

Improved understanding of soil water content at field capacity and estimates from pedotransfer functions

Irrigation and Drainage, Volume 74, Issue 2, Page 516-528, April 2025.
Abstract The soil water content at field capacity, θFC, is a fundamental variable for irrigation and agriculture. This study determines the optimal tension (−33 or −10 kPa) of deriving θFC which best matches the in situ field measurements following the Veihmeyer procedure.

Prediction model of soil water infiltration under moistube irrigation

Irrigation and Drainage, Volume 74, Issue 1, Page 117-127, February 2025.
Abstract As a new type of underground water‐saving irrigation method, moistube irrigation has great potential for promotion and development. However, the multi‐factor interaction influence and water infiltration prediction model of soil water infiltration under moistube irrigation need to be improved.

Méthode d'évaluation de l'action de conseil en irrigation IRRIPARC en régions Nord-Pas-de-Calais et Picardie

Sciences, Eaux & Territoires, 2005
Parmi les nombreuses actions de conseil en irrigation développées en France, trop peu d'entre elles sont évaluées pour apprécier leur impact sur les pratiques d'irrigation et les bénéfices pour la ressource. Dans cet article, nous proposons une méthode d'

A simple method for evaluating the relative water uptake rate of drip‐irrigated crops

Irrigation and Drainage, Volume 73, Issue 4, Page 1231-1245, October 2024.
Abstract Drip irrigation is widely acknowledged for its water use efficiency, yet evaluating relative water uptake rates (RWURs, ratios between the water uptake rates and the irrigation rates) remains pivotal for effective system design and management.

The role of institutional diversity in sustainable water use: Performance comparison among water user organizations

Irrigation and Drainage, Volume 73, Issue 4, Page 1520-1535, October 2024.
Abstract The aim of this study was to compare the performance of water user organizations (WUOs) in the agricultural sector in terms of their managerial efficiency. A survey was carried out across the study area to evaluate 67 WUOs, including irrigation cooperatives, municipalities, village legal entities (VLEs) and water user associations (WUAs).

Stratégies de gestion des irrigations sur les vertisols de Guadeloupe [PDF]

, 1999
L'irrigation des vertisols de Guadeloupe a connu des échecs imputables à une compréhension insuffisante des mécanismes des transferts hydriques. Les travaux de recherches entrepris par l'Inra et le Cirad ont permis de relier la disponibilité de l'eau ...
