Seyhan Havzası aylık ortalama akım ve yağış verilerinin trend analizi

, 2016
Bu çalışmada, Türkiye'nin önemli su havzalarından biri olan Seyhan Havzası'nın yağış yapısının ve atmosferik sirkülasyon değişiminin akım üzerindeki etkisi analiz edilmiştir. Seyhan havzasında yer alan iki farklı akım gözlem istasyonundan elde edilen aylık ortalama akım değerlerinin ve iki farklı yağış gözlem istasyonundan elde edilen aylık ortalama ...

Changes in Streamflow Statistics and Catchment Land Uses Across Select USGS Gages in Northwest and West‐central Arkansas

Journal of Contemporary Water Research & Education
Since 1901, heavy rainfall events have increased in the United States in both intensity and frequency, and human population in the United States has increased, resulting in significant land use changes.

Analysis of Historical Trends in Hydrometeorological Variables in the Upper Cauvery Basin, Karnataka, India

, 2017
The present study examines the significance and magnitude of trends in the monthly rainfall, monthly mean maximum and minimum daily temperatures and streamflow in the Upper Cauvery Basin, Karnataka for a 30-year period, i.e. 1981–2010.

SWOT Captures Hydrologic Waves Traveling Down Rivers

Geophysical Research Letters, Volume 52, Issue 10, 28 May 2025.
Abstract High discharge events propagate down rivers as flow waves. River wave movements are described theoretically by routing equations or tracked using in‐situ gauge measurements of stage over time at a given location. However, the sparse distribution of gauges makes it challenging to show how stage evolves with along‐river distance as waves ...

Surface Flux Equilibrium Theory‐Derived Evapotranspiration Estimate Outperforms ECOSTRESS, MODIS, and SSEBop Products

Geophysical Research Letters, Volume 52, Issue 10, 28 May 2025.
Abstract Evapotranspiration (ET) is a critical process influencing energy, water, and carbon cycles. Numerous methods have been developed to estimate ET accurately and robustly across diverse scales. Many of these methods are constrained by reliance on remote sensing data, which is prone to gaps, or by the need for model calibration and training.

Anthropogenic drying in central-southern Chile evidenced by long-term observations and climate model simulations

Elementa: Science of the Anthropocene, 2018
The socio-ecological sensitivity to water deficits makes Chile highly vulnerable to global change. New evidence of a multi-decadal drying trend and the impacts of a persistent drought that since 2010 has affected several regions of the country, reinforce

Functional Relationships Reveal Large Differences in Streamflow Response to eCO2‐Vegetation in Global Water Models

Geophysical Research Letters, Volume 52, Issue 9, 16 May 2025.
Abstract Rising CO2 levels substantially impact vegetation characteristics and potentially the water cycle. Using 14 global water models, we assess how elevated CO2 (eCO2) affects streamflow (Q) via vegetation dynamics in the period 1901 to 2020. Our results reveal considerable variability in model simulations, with discrepancies not only in magnitude ...

Comparing surface water supply index and streamflow drought index for hydrological drought analysis in Ethiopia

Heliyon, 2022
Recently, floods and drought have become common natural hydroclimatic hazards in several countries. Consequently, the identification of an appropriate drought index is now a challenging task for researchers.

On Risk of Rain on Snow Over High‐Latitude Coastal Areas in North America

Geophysical Research Letters, Volume 52, Issue 9, 16 May 2025.
Abstract Extreme floods and landslides in high‐latitude watersheds have been associated with rain‐on‐snow (ROS) events. Yet, the risks of changing precipitation phases on a declining snowpack under a warming climate remain unclear. Normalizing the total annual duration of ROS with that of the seasonal snowpack, the ERA5 data (1941–2023) show that the ...

Storage Dynamics and Groundwater–Surface Water Interactions in a Drought Sensitive Lowland Catchment: Process‐Based Modelling as a Learning Tool

Hydrological Processes, Volume 39, Issue 5, May 2025.
The past two decades have been dominated by negative anomalies in annual rainfall, causing a general lowering of water tables and persistent storage deficits. Spatio‐temporal patterns of recharge are also strongly influenced by vegetation cover, with coniferous forests having high evapotranspiration losses that inhibit groundwater recharge. Most stream
