Indicator name: SDI

Code: HYD12
Category: Hazard (UNISDR)
Type: Single
Pilot Study: 3
Reference: Nalbantis and Tsakiris (2008)

Description

Streamflow Drought Index: drought severity index based on the cumulative streamflow for overlapping periods of 3, 6, 9, 12 months within the hydrological year. Positive SDI values reflect wet conditions while negative values indicate a hydrological drought. Based on the SDI, five states of hydrological drought are defined.

Description

This dataset represents the Streamflow Drought Index (Nalbantis & Tsakiris 2009) calculated for the LTER site Z�belboden, Pilot study 1 of the OrientGate project. Future climate projections were derived for the IPCC A2-scenario (GCM ECHAM5) for three time slices: 2025-2035, 2045-2055 and 2085-2095. We used downscaling scenarios for Austria reclip:century (http://reclip.ait.ac.at/reclip_century/) together with the weather generator ClimGen (St�ckle et al. 1999). The latter was calibrated with meteorological data measured at the site.

Type: vector-shapefile
Framework: hazard_UN-DRR
Institute: CMCC
Contact: monia.santini@cmcc.it
Scenario: BASE
Time Frequency: 30y
Spatial Resolution: 1:300000
Temporal Subset: 1976-2005
Reference: Nalbantis and Tsakiris 2008

Description

This dataset represents the frequency of classes of the Streamflow Drought Index (SDI; Nalbantis and Tsakiris 2008) calculated for six significant hydrographic basins in Puglia (IT), namely Fortore, Candelaro, Cervaro, Carapelle, Ofanto, Bradano. The frequency was calculated for multi-month periods (3, 6, 9, 12 months) along a 30-year time frame from 1976 to 2005 being the baseline of Pilot 3. Streamflow data were derived from hydrological modeling by ArcSWAT driven by regional climate simulations with COSMO-CLM, as performed in the OrientGate project. The dataset contains information on the basin name (NOME), surface in square kilometers (area_km2) and the SDI for each different intra-annual period and class codified as below: SDIX_Y, where X=1,2,3,4 with 1=3-month period October-December; 2=6-month period October-March; 3=9-month period October-June; 4=12-month period October-September and with Y being: N=Null drought; L=Low drought; M=Medium drought; H=High drought; E=Extreme drought.

Description

This dataset represents the frequency of classes of the Streamflow Drought Index (SDI; Nalbantis and Tsakiris 2008) calculated for six significant hydrographic basins in Puglia (IT), namely Fortore, Candelaro, Cervaro, Carapelle, Ofanto, Bradano. The frequency was calculated for multi-month periods (3, 6, 9, 12 months) along a 30-year time frame from 2021 to 2050 under RCP4.5 IPCC-AR5 emission scenario being the medium term future period in the Pilot 3. Streamflow data were derived from hydrological modeling by ArcSWAT driven by regional climate simulations with COSMO-CLM, as performed in the OrientGate project. The dataset contains information on the basin name (NOME), surface in square kilometers (area_km2) and the SDI for each different intra-annual period and class codified as below: SDIX_Y, where X=1,2,3,4 with 1=3-month period October-December; 2=6-month period October-March; 3=9-month period October-June; 4=12-month period October-September and with Y being: N=Null drought; L=Low drought; M=Medium drought; H=High drought; E=Extreme drought.
