Session Two, August 1. Somalia, like many countries, is affected by frequent climate-related hazards such as floods, droughts and tropical storms. The overall objective of the study was to assess the flood hazard and flood risk of Lower Awash Sub- Therefore, this study will help to fill the existing gap on available information and identify the areas exposed for flood hazard and elements at risk. For example, SWALIM is using satellite imagery in near-real-time to detect areas at risk of flooding and subsequent associated risks to support response agencies in planning and allocating resources. Flood frequency has increased in Somalia over the past 20 years, resulting in the disruption of people’s livelihoods and the economy at large. Remote sensing methods based on optical and medium resolution imagery are limited in their applicability. In an interview with a space scientist, Dr. Ezekiel Eguaroje (2018) of the National Centre for Remote Sensing, Jos, Nigeria said: “Remote sensing and GIS are key in the management of flood disasters everywhere in the world. This Attempting to put down future proposed outlines for the establishment of a Flood Management Unit in collaboration with the different related sectors. Utilisation of remote sensing data and GIS for flood disaster management in Nigeria Published on 27 Oct 2018 , by Monday Yakubu The slow but gradual and steady change in climatic conditions resulting to global warming is increasingly posing a great threat to the environment and existence of man on earth. In addition, participants learn to access digital elevation and terrain data, as well … Flood monitoring and mapping using passive microwave remote sensing in Namibia. Thus, it is possible to obtain coverage of the flood inundated area prior, during and after the flood event for flood inundation mapping and monitoring. They were processed for creating a maximum water extent map and for estimating inundation areas. Flood response and damage assessment. Flood response and damage assessment. The use of remote sensing to monitor surface water bodies has gradually matured. : Conf. Near Realtime Global Hydrological Simulation and Flood Monitoring Demonstration System.

Schumann et al. Jianfeng Li1,3,4,5, Jiawei Wang1,3,4,5 and Huping Ye2. Flood monitoring and mapping using passive microwave remote sensing in Namibia. The flood monitoring system is crucial for residents who are exposed to the flood disaster. The data and information need to be transferred or delivered quickly and accurately to the person who are being entrusted with this system. First, the water bodies mask was created from observing the water pixels in Near Infrared (NIR) and. Although the classification and object extraction is difficult because of the imaging mechanism is quite different from multispectral images, Radar Images find special application in the flood monitoring due to the properties of all-weather, day-and-night and capability of cloud-piercing. Optical remote sensing from geostationary platform (INSAT-3D/3DR) provides rapid and valuable information on cloud patterns and meteorological parameters (rainfall); however, unable to image the surface water conditions in presence of cloud. A complete approach to efficient and precise flood monitoring requires multiple fields of expertise, from image processing to hydrologic monitoring. There will be four, 1 hour sessions, in the form of webinars, from 16 March to 06 April 6, 2016. However, the spatial scales at which flooding occurs are often beyond the capacity of regional flood monitoring schemes, so remote sensing – using highly advanced sensors attached to satellites – is a promising solution to gathering the information necessary for future flood predictions. Generated flood maps indicated changes in the flood extent of the flooding seasons from 2010 and 2014–2016 with variations in spatial extent appearing greater in the TerraSAR-X and RadarSAT-2 higher resolution maps. In this approach, the moderate resolution imaging spectrometer data from the Terra and Aqua satellites are used to perform broad-scale monitoring for flood tracking at the regional level (250 m / pixel) to generate flood detections/alerts.Based on these alerts, the Earth Observing-1 (EO-1) mission … Ser. Frequent coverage of the earth surface is done through, in particular, satellite remote sensing. Figure 2.2 Satellite remote sensor for flash flood alerting 6 Figure 2.3 Three major part of Telemetry system 7 Figure 2.4 Mesh network system 10 Figure 2.5 Flood monitoring and alert using local data sensing or Telemetry [12] 11 Figure 2.6 Website of Flood Monitoring and Alert system by JPS. Improving flood response in Somalia through remote sensing. 4 Remote Sensing and Natural Disaster Management . Postdoctoral Scholar, CEES. 1 Dept. In this article we will focus on naturally occurring disasters and how remote sensing and location intelligence play a key role in the entire life-cycle of a disaster management plan. For the example mentioned, remote sensing rainfall records have their intrinsic errors [18] and in addition the rainfall estimates need to be translated to agricultural and economic losses. However, it could also be used as a monitoring tool to assess finer-scale flooding (such as the failure of individual levees) or to detect the early stages of a flood event. Satellite data of inundation have been used to gather Klemas, V., 2015. Image: NASA ARSET Monitoring All Types of Disaster.
