| description | Floods, as a major natural disaster, affect many parts of the world, not including developed countries. Due to this natural disaster, every year there are
losses of human life and damage to the territory for millions of euros. Damage and losses can be prevented and limited by providing reliable information
to institutions and citizens through flood hazard models and maps (Demir, 2015). Hydraulic models and digital cartography are essential for municipal
planning, for civil protection emergency plans, for a correct design of works to prevent hydrogeological phenomena (Goodell and Warren, 2006). In the
first days of November 2018, Sicily was affected by a phase of disturbed weather, characterized by intense and abundant rains that caused serious damage
to the community and the territory.
Geographical information systems (GIS) using spatial data are able to integrate hydraulic models for the simulation of flood events and are capable of
drawing up maps of hydraulic hazard and estimating damage from hydrogeological instability (Demir, 2015). The GIS integrated with the hydraulic
model is able to estimate the flood profile with a fixed return time. The hydraulic model used was developed after 1970 by the River Software Analysis
System (HEC-RAS) hydrological engineering center of the United States Army Corps of Engineers (USACE), and is now widely used in Europe and
America. GIS and HEC-RAS models have been successfully used to obtain flood maps of the Waller River in Texas (Tate et al., 2002), Ohio Swan River
Basin (Wiles and Levine, 2002), Atrato River in Colombia (Mosquera-Machado and Ahmad, 2007), Vistula River in Warsaw, Poland (Gutry-Korycka
et al., 2006), the Gordon River in France (Sheffer et al., 2008), northwestern Colombia (Mosquera-Machado and Ahmad, 2007), central-eastern Dhaka
in Bangladesh (Masood and Takeuchi, 2012), and Onaville in Haiti (Heimhuber, 2015). Celik et al. analyzed the Kozdere Stream 2004 flood in Istanbul
using HEC-RAS and GIS (Celik et al., 2012). Sole et al. they have drawn up risk maps of the Basilicata region (Italy), generating profiles of free-flowing
currents for different return times (30, 200 and 500 years) (Sole et al., 2007). Masood and Takeuchi used HEC-RAS and GIS to assess flood danger, vulnerability
and hydraulic risk in Middle East Dhaka (Masood and Takeuchi, 2012), obtaining flood maps for floods with a 100-year return time. Sarhadi
et al. investigated forecasting models of flooding in rivers in southeastern Iran using HEC-RAS and GIS (Sarhadi et al., 2012). Heimhuber et al. they used
HEC-RAS and GIS to perform the simulations in one-dimensional and non-stationary motion conditions for the design of the large Lan Couline channel
(Heimhuber et al., 2015). The aim of this study is to study models to simulate scenarios for flood events in the Milicia River basin using the GIS and
HEC-RAS for different return periods (50, 100 and 300). |
