Spatiotemporal Characteristics of Droughts and Their Propagation during the Past 67 Years in Northern Thailand

open access: yesAtmosphere, 2022
Droughts grow concurrently in space and time; however, their spatiotemporal propagation is still not fully studied. In this study, drought propagation and spatiotemporal characteristics were studied in northern, northeastern, and central Thailand (NNCT).

Evaluation of drought propagation in an ensemble mean of large-scale hydrological models [PDF]

open access: yes, 2012
Hydrological drought is increasingly studied using large-scale models. It is, however, not sure whether large-scale models reproduce the development of hydrological drought correctly.

Resistance to Drought and Salt Stress after Regeneration and Micropropagation. [PDF]

open access: yes, 2013
Investigation was made to confirm the stability of drought and salt stress tolerance in cauliflower (Brassica oleracea var.botrytis) mutants after regeneration and micropropagation.

Dynamics of hydrological droughts propagation in mountainous catchments

open access: yesMiscellanea Geographica, 2022
Abstract In the study, hydrological drought was identified assuming that the occurrence of river low-flow is a symptom of drought, and is also a good estimator of its progress. The research was conducted in the upper Dunajec river catchment, for which a series of daily discharges from 20 gauging stations during the period 1989–2018 were ...

A precipitation recycling network to assess freshwater vulnerability : challenging the watershed convention [PDF]

open access: yes, 2019
Water resources and water scarcity are usually regarded as local aspects for which a watershed-based management appears adequate. However, precipitation, as a main source of freshwater, may depend on moisture supplied through land evaporation from ...

Progress and bottlenecks in the early domestication of the perennial oilseed Silphium integrifolium, a sunflower substitute [PDF]

open access: yes, 2018
Silflower (Silphium integrifolium Michx.) is in the early stages of domestication as a perennial version of oilseed sunflower, its close relative. Grain crops with deep perennial root systems will provide farmers with new alternatives for managing soil ...

Probabilistic long‐term hydrological drought forecast using Bayesian networks and drought propagation [PDF]

open access: yesMeteorological Applications, 2019
AbstractEffective drought mitigation plans that can handle severe drought conditions require reliable drought forecasts. A probabilistic hydrological drought forecasting method was developed using Bayesian networks that incorporate dynamic model predictions and a drought propagation relationship.

The effect of climate type on timescales of drought propagation in an ensemble of global hydrological models [PDF]

open access: yesHydrology and Earth System Sciences, 2018
Drought is a natural hazard that occurs at many temporal and spatial scales and has severe environmental and socioeconomic impacts across the globe.

Estimating propagation probability from meteorological to ecological droughts using a hybrid machine learning copula method [PDF]

open access: yesHydrology and Earth System Sciences, 2023
The impact of droughts on vegetation is essentially manifested as the transition of water shortage from the meteorological to ecological stages. Therefore, understanding the mechanism of drought propagation from meteorological to ecological drought is ...

Automation of hydrological drought typology to study drought propagation in a tropical catchment [PDF]

open access: yes, 2021
Understanding how droughts propagate through the hydrological cycle from precipitation to streamflow and groundwater is important for improving water and risk management policies. At the catchment scale, the analysis of drought propagation and classification into drought types is usually done manually, which can be time consuming and difficult to ...
