{"cited_by_count":877503,"description":"This cluster of papers focuses on the monitoring, assessment, and impacts of drought at a global scale. It covers various aspects such as the development of drought indices, the influence of global warming and climate change on drought severity and frequency, hydrological implications, remote sensing techniques for drought monitoring, and the use of evapotranspiration data. The research also delves into the challenges and future directions in drought assessment.","display_name":"Hydrology and Drought Analysis","domain_id":"3","external_ids":{"openalex":"https://openalex.org/T11186","wikipedia":"https://en.wikipedia.org/wiki/Drought_monitoring"},"field_id":"23","id":"T11186","keywords":[{"display_name":"Standardized Precipitation Index","id":"standardized-precipitation-index","score":0.828,"url":"https://openalex.org/keywords/standardized-precipitation-index"},{"display_name":"drought monitoring","id":"drought-monitoring","score":0.7391,"url":"https://openalex.org/keywords/drought-monitoring"},{"display_name":"drought indices","id":"drought-indices","score":0.7455,"url":"https://openalex.org/keywords/drought-indices"},{"display_name":"drought severity","id":"drought-severity","score":0.8002,"url":"https://openalex.org/keywords/drought-severity"},{"display_name":"meteorological drought","id":"meteorological-drought","score":0.893,"url":"https://openalex.org/keywords/meteorological-drought"},{"display_name":"Standardized Precipitation Evapotranspiration Index","id":"standardized-precipitation-evapotranspiration-index","score":0.7185,"url":"https://openalex.org/keywords/standardized-precipitation-evapotranspiration-index"},{"display_name":"reference evapotranspiration","id":"reference-evapotranspiration","score":0.4357,"url":"https://openalex.org/keywords/reference-evapotranspiration"},{"display_name":"hydrological drought","id":"hydrological-drought","score":0.7902,"url":"https://openalex.org/keywords/hydrological-drought"},{"display_name":"agricultural drought","id":"agricultural-drought","score":0.7778,"url":"https://openalex.org/keywords/agricultural-drought"},{"display_name":"drought forecasting","id":"drought-forecasting","score":0.7006,"url":"https://openalex.org/keywords/drought-forecasting"},{"display_name":"potential evapotranspiration","id":"potential-evapotranspiration","score":0.3224,"url":"https://openalex.org/keywords/potential-evapotranspiration"},{"display_name":"drought duration","id":"drought-duration","score":0.741,"url":"https://openalex.org/keywords/drought-duration"},{"display_name":"drought frequency","id":"drought-frequency","score":0.7939,"url":"https://openalex.org/keywords/drought-frequency"},{"display_name":"drought assessment","id":"drought-assessment","score":0.8419,"url":"https://openalex.org/keywords/drought-assessment"},{"display_name":"Penman-Monteith equation","id":"penman-monteith-equation","score":0.3359,"url":"https://openalex.org/keywords/penman-monteith-equation"},{"display_name":"drought early warning","id":"drought-early-warning","score":0.7588,"url":"https://openalex.org/keywords/drought-early-warning"},{"display_name":"precipitation deficit","id":"precipitation-deficit","score":0.4319,"url":"https://openalex.org/keywords/precipitation-deficit"},{"display_name":"drought trends","id":"drought-trends","score":0.9525,"url":"https://openalex.org/keywords/drought-trends"},{"display_name":"drought mitigation","id":"drought-mitigation","score":0.2269,"url":"https://openalex.org/keywords/drought-mitigation"},{"display_name":"Palmer Drought Severity Index","id":"palmer-drought-severity-index","score":0.4689,"url":"https://openalex.org/keywords/palmer-drought-severity-index"},{"display_name":"drought impacts","id":"drought-impacts","score":0.3575,"url":"https://openalex.org/keywords/drought-impacts"},{"display_name":"drought management","id":"drought-management","score":0.4041,"url":"https://openalex.org/keywords/drought-management"},{"display_name":"drought risk","id":"drought-risk","score":0.3198,"url":"https://openalex.org/keywords/drought-risk"},{"display_name":"evapotranspiration estimation","id":"evapotranspiration-estimation","score":0.3035,"url":"https://openalex.org/keywords/evapotranspiration-estimation"},{"display_name":"drought risk assessment","id":"drought-risk-assessment","score":0.7933,"url":"https://openalex.org/keywords/drought-risk-assessment"}],"legacy_keywords":["Drought","Monitoring","Global Warming","Hydrological","Indices","Remote Sensing","Climate Change","Evapotranspiration","Severity","Frequency"],"openalex_id":"https://openalex.org/T11186","source_created_date":"2024-01-23T15:27:09","source_updated_date":"2026-10-17T03:02:00","subfield_id":"2306","url":"/topics/T11186","works_api_url":"https://api.openalex.org/works?filter=topics.id:T11186","works_count":67453,"label":"Hydrology and Drought Analysis","provider":"openalex","revision":"acbcee881f2f0ed3","taxonomy_revision":"f050b5d4780b1289","title":"Hydrology and Drought Analysis","kind":"topic-directory","aeo_cohort":"topic-directory","catalogue_revision":"f050b5d4780b1289","numeric_address":"36240506703446771","address_version":"morton4x16-v1","coordinates":[3,23,2306,11186],"answer_status":"Directory metadata; local answer requires separate source review","truth_status":"Subject descriptor, not a factual answer or a demonstrated knowledge gap","reviewed_answer":null}
