摘要

本研究在巴洛德地区进行,以评估气象干旱事件,用于预防和未来水资源管理规划。研究区域降雨量不足,降雨量变化较大。从1990年到2020年,降雨量异常指数(RAI)被用于计算该地区的气象干旱和监测干旱和湿润期。将来自IMD 0.25º×0.25º空间分辨率的每日网格数据的降雨数据集与地理信息系统(GIS)环境相结合。该指数的结果显示,2000年、2002年、2008年和2009年出现了最高的负值,这些年份面临着严重的干旱事件。这项研究的结果可以帮助制定抗旱计划,通过有效的水资源管理来减轻风险。

Assessment of meteorological drought in Balod district, India through GIScience and Remote sensing
The present study was conducted in Balod district to assess meteorological drought events for prevention and future water resource management planning. The study area has a deficit in rainfall with a higher rainfall variation. From 1990 to 2020, the rainfall anomaly index (RAI) was used to calculate meteorological drought and monitor dry and wet periods in the area. Rainfall datasets from IMD daily gridded data of 0.25º × 0.25º spatial resolution were combined with the Geographic information system (GIS) environment. The results from the index revealed that the highest negative values were observed in the years 2000, 2002, 2008 and 2009 which have faced severe drought events. The findings from the study can assist in making a drought preparedness plan to mitigate the risk with effective water resources management.
