Drought Analysis of Alvand Boundary River Using Remote Sensing Data
Extended abstract 1- Introduction The study of the behavior of rivers in the arid and dry areas is one of the most important tasks in the country. Because the area has increased the effects of drought due to the sensitivity of the area and rainfall shortage, it causes changes in the flow and sediment regime, water resources, agriculture, and so on. Since plants react more precisely to t...
متن کاملevaluating a new combined drought index based on remote sensing data (rcdi) in central iran
monitoring and evolution of drought is the first step in any drought management system. in this study, evaluation of a new indexa new method is provided to monitor the severity of drought with remote sensing combined drought index (rcdi). the index is based on the fact that drought is a natural phenomenon caused by a combination of various factors such as a shortage in the amount of precipitati...
متن کاملAssessing the Trend of Spatio-temporal Drought Changes Using Remote Sensing Time Series Data in Central Khuzestan Province
Introduction: As a dreadful natural disaster caused by a severe reduction in precipitation rate, drought brings about, compared with other natural disasters, far-reaching spatial and temporal consequences, incurring severe damages. On the other hand, in late the 20th century, drought monitoring approaches underwent a paradigm shift, and advances in remote sensing and earth observation technolog...
متن کاملApplying narrowband remote-sensing reflectance models to wideband data.
Remote sensing of coastal and inland waters requires sensors to have a high spatial resolution to cover the spatial variation of biogeochemical properties in fine scales. High spatial-resolution sensors, however, are usually equipped with spectral bands that are wide in bandwidth (50 nm or wider). In this study, based on numerical simulations of hyperspectral remote-sensing reflectance of optic...
متن کاملdrought monitoring in unirrigated lands based on the remote sensing technique
regional vegetation plays an important role in modeling ecosystem changes and conservation. meteorological drought indices which are directly obtained from such meteorological data as precipitation can't be useful in drought monitoring if those data are absence. therefore, remote sensing techniques may provide an efficient technique for drought monitoring. in this study, the values of norm...
