Influence of Drain and Operational Parameters on Backwash Cleaning Efficiency in a Commercial Sand Filter Model

Irrigation and Drainage, EarlyView.
ABSTRACT Some studies have demonstrated the influence of the drainage system design on the hydraulic behaviour and on the expansion of the filter bed during the backwashing process, with a presumed effect on removal efficiency. The objective was to evaluate the influence of the drainage system design of a commercial sand filter model, the operating ...

Hydrological Drought Index Insurance for Irrigated Agriculture [PDF]

, 2017
Los riesgos de escasez de agua en sistemas de regadío son importantes en los países semi-áridos y es probable que aumenten debido al cambio climático. De ahí deriva el interés en ofrecer a los agricultores la posibilidad de proteger la estabilidad de los ingresos de las explotaciones de regadío frente a este riesgo.

Spatiotemporal Changes and Climate Driving Factors of Compound Precipitation‐Temperature Extreme Events Across Global Land Areas

International Journal of Climatology, EarlyView.
During the period 1901–2024, the dominant proportion of compound dry‐warm extremes in annual, June–July–August (JJA), and December–January–February (DJF) occurrences was the highest among the four types of compound precipitation and temperature extremes across global land areas, accounting for 40.1%, 50.3%, and 28.0%, respectively.

A Zonal‐Meridional Projection Method for Quantifying Global Land‐Ocean Moisture Transport

International Journal of Climatology, EarlyView.
We present a physically consistent and computationally efficient method to quantify global coastal moisture transport by projecting vertically integrated moisture flux onto signed land–ocean boundary segments. The signed projection naturally distinguishes ocean‐to‐land inflow and land‐to‐ocean outflow without explicit directional classification ...

Agricultural Transformation and the Politics of Hydrology in Northern Thailand

Development and Change, 2003
AbstractTensions over water resources in upland areas of northern Thailand are often attributed to reductions in water supply caused by forest clearing. This article argues that the hydrological evidence for such reductions in supply is very weak and that, rather, the key hydrological issue in upland catchments is a significant increase in water demand,

Low‐Intensity Precipitation Dominates Peninsular Spain (1961–2022)

International Journal of Climatology, EarlyView.
Spatial analysis across Spain shows a shift in precipitation regimes (1961–2022) toward more frequent low‐intensity precipitation and reduced high‐intensity events, with localised increases in heavy precipitation along some coastal areas. This redistribution—captured through changes in precipitation frequency (RF) and volumetric contribution (RC ...

Intercomparison of a Regional Climate Model Ensemble for Selected European Catchments

International Journal of Climatology, EarlyView.
This study analyzes a regional climate model ensemble for water cycle and water resource research with two models. Results show that ICON generally outperforms TSMP1 simulations, mainly with 2‐m temperature and precipitation. These findings serve as a baseline evaluation that shows how key structural differences influence the model skill.

A New Hydroclimatic Signature: Negative NAO Dominance Under Weak La Niña Conditions During the 2025–2026 Northwest Africa Floods

International Journal of Climatology, EarlyView.
Conceptual hydroclimatic pathway linking the concurrent negative North Atlantic Oscillation (NAO) phase and weak La Niña conditions to extreme February rainfall and flash flooding in Northwest Africa. ABSTRACT The winter of 2025–2026 in Morocco exhibited a rapid hydroclimatic transition from prolonged drought to widespread flooding, representing an ...

One Hundred Years of the German Soil Science Society (DBG) 1926–2026: Origins, Facts, and Background of an Eventful History

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT On its 100th anniversary in 2026, the German Soil Science Society (DBG) is looking back not only on an eventful history with traditions and impressive achievements but also with painful interruptions and ruptures. One curious fact is that the DBG was initially founded as the national section of the International Soil Science Society (ISSS ...
