challenges encountered. Floodplain mapping was one such solution. Floodplain mapping is a technique for identifying areas that are prone to recurring flooding from nearby rivers, lakes, streams, and the sea, as well as providing information on the spatial distribution of flood construction levels.For many years, numerous researchers have studied floodplain mapping. It has lately been coupled with tools like HEC-RAS and ArcGIS to conduct more in-depth research on the subject.
worldwide scale over time. Floodplain mapping is one of the key acts that must be conducted in order to determine, decide, and take action for flood risk management, given the significance and gravity of the effects of floods. This paper looks at the same subject from a geoinformatics perspective, using GIS software. GIS tools such as HEC-RAS, HEC-HMS, ArcGIS, and others are used to define floodplains. Many scholars have worked on this topic previously, and there is a wealth of information available. However, a new user learning the material for the first time may find things difficult and complex. There are many floodplain mapping approaches accessible, which may make it difficult for a new user to choose one for his own task. This paper attempts to assist a new user by categorizing previously examined studies (2000-2021) into three categories: Flood Frequency Analysis Methods, Digital Elevation Models (DEMs), and Softwares used.
However, a user may be unsure about which technique to employ and how to apply it when pursuing a study in the subject for the first time. After reviewing prior research on floodplain mapping by a lot of scholars, this work has compiled and classified a few studies based on the methodology employed and presented them in a clear manner.

Key Words: Floodplain mapping, Software, Hec-HMS, Hec-RAS, ArcGIS, Remote Sensing
Numerous research papers in the last two decades were dedicated to the topic of floodplain mapping. The topic and its study however, became advanced with the time and the use of softwares facilitated the study of floodplain mapping. This paper tries to focus on the parameters of software, Digital Elevation Model (DEM) and Flood Frequency Analysis methods that have been majorly used to study floodplain mapping. Following is a brief look at the research papers that were studied:
1. INTRODUCTION For a long time, India has been plagued by natural disasters. Floods, on the other hand, have become more common in recent years. These floods have wreaked havoc on people's lives and property. Hyderabad (2000), Ahmedabad (2001), Delhi (2002, 2003), Chennai (2004), Mumbai (2005), Surat (2006), Kolkata (2007), Jamshedpur (2008), Delhi (2009), Guwahati and Delhi (2010), Kedarnath (2013), Srinagar (2014), Gujarat, Chennai (2015), Assam, Hyderabad (2016), Gujarat (2017), Kerala (2018), Kerala, Madhya Pradesh, Karnataka, Maharashtra, Gujarat (all 2019), Assam, Hyderabad (2020) and the recent ones of Uttarakhand and Maharashtra- Mahad and Chiplun (2021) were the worst floods in the recent two decades. The regular occurrence of floods necessitated a thorough examination of the
