With the global climate change, drought disasters occur frequently. Drought prediction is an important content for drought disaster management, planning and management of water resource systems of a river basin. In this study, a short-term drought prediction model based on deep belief networks DBNs is proposed to predict the time series of different time-scale standardized precipitation index S...

Extreme droughts like the recent 2011–2013 drought impacting the central and western United States present a challenge to sustaining livestock ranching operations and the ecosystem goods and services they produce. Wyoming ranchers manage half of this drought-prone state and are at the forefront of this challenge. We examined Wyoming ranchers’ drought management strategies and how ranch characte...

Drought is a naturally occurring event that is associated with virtually all climatic regions. Given its slow onset and other characteristics, including its spatial dimensions and duration, impacts are difficult to assess and have been, historically, poorly documented. These impacts are strongly influenced by a society’s exposure to the hazard and the vulnerability of that society to the hazard...

The extent of utilization of drought management practices by the farmers of Tafresh County was studied in a descriptive-correlational research. Statistical population consisted of all farmers in Tafresh County which summed up to around 9061 people out of which 300 farmers were taken as the sample in accordance with Cochran’s formula. The main tool of the study was a questionnaire. The validity ...

Recent drought events in the United States and the magnitude of drought losses indicate the continuing vulnerability of the country to drought. Until recently, drought management in many states, including Nebraska, has been largely response oriented with little or no attention to mitigation and preparedness. In 1998, Nebraska began to revise its drought plan in order to place more emphasis on m...

This paper describes the research project on the development of an ontology-based semantic search system for drought management of the Chi River Basin (CRB), Thailand. The research methods included Ontology Development 101 by adopting Noy & McGuinness (2001) and Ontology-based Application Management framework by adopting Buranarach et al. (2012). Seventeen experts including ten experts in the a...

In recent decades, various kinds of remote sensing-based drought indexes have been proposed and widely used in the field of drought monitoring. However, the drought-related software and platform development lag behind the theoretical research. The current drought monitoring systems focus mainly on information management and publishing, and cannot implement professional drought monitoring or par...

California experienced an extraordinary drought from 2012–2015 (which continues into 2016). This study, from an operational perspective, reviewed the development of this drought in a hydroclimatic framework and examined its characteristics at different temporal and spatial scales. Observed and reconstructed operational hydrologic indices and variables widely used in water resources planning and...

Drought is a normal, recurring feature of climate. The characteristics of this hazard, along with its far-reaching impacts, make its effects on society, economy, and environment difficult to identify and quantify. A national drought watch system has been recommended as a necessary component of drought assessment and management. The National Drought Mitigation Center, in collaboration with other...
