Ce arranging within the basin. One limitation of the study is the fact that we used only SPI to detect drought intensities. Within the future, we program to add evapotranspiration and calculate the SPEI indicator, which can give more complex information regarding meteorological circumstances Betamethasone disodium Biological Activity influencing drought events, especially for agricultural and forestry applications. In addition, within this study only annual sum of precipitation was applied and therefore seasonal variability of drought was not detected. Whilst this really is to some extent justified for this area given that precipitation is concentrated in only a couple of months per year, inside a future study month-to-month and seasonal precipitation variations could also be explored. In addition, as a future study, we strategy to examine drought analyses according to different sources of 20(S)-Hydroxycholesterol site rainfall information, such as the Soil Moisture to Rainfall (SM2RAIN) [76] algorithm to estimate rainfall depending on soil moisture time series. The SM2RAIN is determined by the inversion in the hydrological water balance, for estimation of rainfall from soil moisture observations. Within this strategy the soil is assumed as reservoir made use of for measuring the quantity of rainfall [77]. This strategy provides independent rainfall product using a different error structure and allows integration with other satellite-based rainfall merchandise. Based on [76], the SM2RAIN strategy may be helpful in regions for which satellite rainfall information are affected by greater errors or not offered. For the reason that Northwest Algeria could be the region exactly where water scarcity is high, we are going to execute analysis that will show prospective use of SM2RAIN as indirect source of rainfall to detect meteorological drought, like seasonal variations.Author Contributions: Conceptualization, M.A.; methodology, M.A., A.W., H.M. and N.K.; software, M.A. plus a.K.T.; formal analysis, M.A., A.W.; validation: M.A., A.W. and N.K.; investigation, M.A., A.K.T., A.W. and H.M.; data curation, M.A.; writing–original draft preparation, M.A., A.W. and N.K.; writing–review and editing, M.A., A.W. and N.K.; visualization, A.W.; supervision, M.A., A.W. and N.K.
