Abstract
In recent years, significant flood events have occurred in various parts of the world. The most important reasons for these events are global warming and consequent imbalances in climate and rainfall regimes. Many studies are performed to prevent the loss of life and property caused by floods. Many methods have been developed to predict future floods and possible affected areas. Developing computer and numerical calculation methods gives opportunities to make simulations of flood hazards. One of the affected areas, which is also one of the world’s first residential districts at Hatay in Turkey, is the Amik Plain. In this study, the floods on the Amik Plain in Hatay province are analyzed. Hatay airport was also affected during floods since 2012 and serious material damage occurred. For this purpose, Google Earth Pro software was used to obtain maps of the basin where the airport is located and the rivers it contains. Afterwards, Hydrologic Engineering Center’s River Analysis System module (HEC-RAS) was used for the hydraulic and hydrological definitions of the river basin. The results of numerical models are presented as simulated maps.
Highlights
Flooding is a condition that causes water and soil environments to be disturbed in areas that are not normally submerged owing to increased flow and rising level in a stream
The main purpose of this study is to investigate how vulnerable the Amik plain is against flood disasters using geographic information systems and Hydrologic Engineering Center’s River Analysis System module (HEC-RAS)
According to the ESRI results, it is possible to see that a huge part of the plain including Hatay airport
Summary
Flooding is a condition that causes water and soil environments to be disturbed in areas that are not normally submerged owing to increased flow and rising level in a stream. This situation may harm humans and animals and damage land and property near the river. A total of 634 people lost their lives in these floods, 810,000 hectares of land were left under water, and the total loss was 3.717 billion dollars. During this period, the distribution of flood losses by sectors was found to be 45% agricultural areas, 32% settlements and infrastructure, 7% portable goods and vehicles, 1%. The main purpose of this study is to investigate how vulnerable the Amik plain is against flood disasters using geographic information systems and HEC-RAS
