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).

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 ...

Hydrological Drought Instantaneous Propagation Speed Based on the Variable Motion Relationship of Speed‐Time Process

open access: yesWater Resources Research, 2018
It is difficult to predict and track the propagation of a hydrological drought because it is hard to determine its propagation speed. We propose a useful framework for calculating the hydrological drought instantaneous propagation speed which includes ...

Drought Propagation in Brazilian Biomes Revealed by Remote Sensing

open access: yesRemote Sensing, 2023
Drought events have been reported in all Brazilian regions every year, evolving slowly over time and large areas, and largely impacting agriculture, hydropower production, and water supplies. In the last two decades, major drought events have occurred over the country, such as the 2010 and 2015 events in the Amazon, the 2012 event in the Pampa, and the
