  • Degroeve, T., Kugler, Z, and Brakenridge, G. R., 2007, Near Real
    Near Real Time Flood Alerting for the Global Disaster Alert and Coordination System Tom De Groeve Zsofia Kugler Joint Research Centre of the European Joint Research Centre of the European Commission Commission [email protected] [email protected] G. Robert Brakenridge Dartmouth Flood Observatory [email protected] ABSTRACT A new flood monitoring module is in development for the Global Disaster Alert and Coordination System (GDACS). GDACS is an information system designed to assist humanitarian responders with their decisions in the early onset after a disaster. It provides near-real time flood alerts with an initial estimate of the consequences based on computer models. Subsequently, the system gathers information in an automated way from relevant information sources such as international media, mapping and scientific organizations. The novel flood detection methodology is based on daily AMSR-E passive microwave measurement of 2500 flood prone sites on 1435 rivers in 132 countries. Alert thresholds are determined from the time series of the remote observations and these are validated using available flood archives (from 2002 to present). Preliminary results indicate a match of 47% between detected floods and flood archives. Individual tuning of thresholds per site should improve this result. Keywords Flood alerts, disaster alerts, humanitarian aid, microwave remote sensing. INTRODUCTION Of all natural disasters, floods are most frequent (46%) and cause most human suffering and loss (78% of population affected by natural disasters). They occur twice as much and affect about three times as many people as tropical cyclones. While earthquakes kill more people, floods affect more people (20000 affected per death compared to 150 affected per death for earthquakes) (OFDA/CRED, 2006).

  • Djibouti Rapid Response Flood 2019 19-Rr-Dji-40092
    CERF ALLOCATION REPORT ON THE USE OF FUNDS AND ACHIEVED RESULTS DJIBOUTI RAPID RESPONSE FLOOD 2019 19-RR-DJI-40092 Barbara Manzi Resident/Humanitarian Coordinator PART I – ALLOCATION OVERVIEW Reporting Process and Consultation Summary: Please indicate when the After-Action Review (AAR) was conducted and who participated. N/A An AAR was not conducted due to the limited availability of UN staff in relation to the additional workload caused by the response to the Covid-19 pandemic. The government of Djibouti put in place containment measures, including the closure of land and air borders from March until July to limit the spread of the Corona virus. As a result, planned activities of UN agencies were mostly postponed, as national partners, including the Government of Djibouti, slowed down activities and agencies had limited time to deliver planned activities for this year. The recipient agencies have continued to support the government in managing this crisis, which has increased the workload of United Nations staff. However, recipient agencies (FAO, WHO, IOM, WFP, UNDP, UNICEF) were actively involved in the drafting of the RC/HC report. Due to barrier measures and alternate working arrangements put in place as a prevention to Covid- 19, the exchanges were carried out virtually. In addition, the beneficiary agencies worked closely with their implementing partners to report on the progress of activities. As a result, implementing partners, such as the Red Crescent and the Ministry of Social Affairs and Solidarity, have been involved and are aware of the data and information reported here. Please confirm that the report on the use of CERF funds was discussed with the Humanitarian and/or UN Yes ☒ No ☐ Country Team (HCT/UNCT).

  • Community-Based Autonomous Adaptation and Vulnerability to Extreme Floods in Bangladesh: Processes, Assessment and Failure Effects
    Community-Based Autonomous Adaptation and Vulnerability to Extreme Floods in Bangladesh: Processes, Assessment and Failure Effects MD ABOUL FAZAL YOUNUS BSc (Hons), MSc (Geography, Dhaka University), MPhil (Geography, Waikato University) Thesis Submitted For the Degree of Doctor of Philosophy in Discipline of Geographical and Environmental Studies The University of Adelaide August 2010 ABSTRACT ABSTRACT The Intergovernmental Panel on Climate Change’s (IPCC) Fourth Assessment Report (2007), especially Chapter 17: Assessment of Adaptation Practices, Options, Constraints and Capacity demonstrates the importance of adaptation to climate change. The IPCC (2007) warned that the megadelta basins in South Asia, such as the Ganges Brahmaputra Meghna (GBM) will be at greatest risk due to increased flooding, and that the region’s poverty would reduce its adaptation capacity. A key issue in assessing vulnerability and adaptation (V & A) in response to extreme flood events (EFEs) in the GBM river basin is the concept of autonomous adaptation. This thesis investigates autonomous adaptation using a multi-method technique which includes two participatory rapid appraisals (PRA), a questionnaire survey of 140 participant analyses over 14 mauzas in the case study area, group and in-depth discussions and a literature review. The study has four key approaches. First, it reviews the flood literature for Bangladesh from 1980 to 2009 and identifies a general description of flood hazard characteristics, history and research trends, causes of floods, and types of floods. Second, it examines farmers’ crop adaptation processes in a case study area at Islampur, Bangladesh, in response to different types of EFEs (multi-peak with longer duration flood, single-peak with shorter duration flood and single-peak at the period of harvesting), and describes how farmers have been adapting to the extreme floods over time.

However, no publicly available digital flood maps, except for a few aerial photos or post-disaster assessments from UNOSAT, could be found for the country. This report tested an experimental method for assessing the socio-physical vulnerability of Senegal using high capacity remote sensing, machine learning, new social science, and community engagement.

    Arizona’s Worst Disaster The Hassayampa Story 1886–2009 Jim Liggett The Hassayampa River downstream of the Walnut Grove Dam site Water, water, water…There is no shortage of water in the desert but exactly the right amount, a perfect ratio of water to rock. Of water to sand, insuring that wide, free, open, generous spacing among plants and animals, homes and towns and cities, which makes the arid West so different from any other part of the nation. There is no lack of water here, unless you try to establish a city where no city should be. Edward Abbey, Wilderness Reader i The picture on the cover is a photo of a diorama in the Desert Caballe- ros Western Museum in Wickenburg, Arizona, done by George Fuller of Wickenburg. It is the artist’s depiction of the flood wave from the Walnut Grove Dam failure exiting Box Canyon. Photograph of the diorama is courtesy of the Desert Caballeros Western Museum. Back cover: The Hassayampa River Preserve is a virtual desert oasis. The green trees—mostly cottonwoods, willows, and mesquites but also palms and other vegetation—are a result of the constant supply of water. Water appears on the surface here throughout the year as shown in the inset taken after a summer of very low precipitation. Copyright © James A.

  • Executive Summary Bangladesh Monsoon Floods
    Endorsed by the Resident Coordinator on 30 May 2021 Pre-approved by the Emergency Relief Coordinator on 3 June 2021 Anticipatory Action Framework Bangladesh Monsoon Floods Executive Summary This document presents the pilot framework for collective anticipatory action to monsoon floods in Bangladesh, including the forecasting trigger (the model), the pre-agreed action plans (the delivery) and the pre-arranged financing (the money). In addition to the 3 core elements, an investment in documenting evidence and learning is part of the pilot (the learning). The objective of this pilot is to further scale-up the quality and quantity of collective anticipatory humanitarian action to people at risk of predicted severe monsoon flooding of the Jamuna River in Bangladesh. The pilot will cover five highly vulnerable districts (Bogura (Bogra); Gaibandha; Kurigram; Jamalpur; and Sirajganj) with the aim to reach 410,000-440,0001 people ahead of flood peak with multi-sectoral interventions carried out by the United Nations and the Red Cross/Red Crescent in close collaboration with NGOs and the Government through CERF funding. A further ca. 130,000 people will be reached with additional financing and about one million people are to benefit from joint early warning messages. The model makes use of available forecasts with a two-step trigger system to predict severe monsoon floods: • Stage I: Readiness trigger is reached when the water discharge at the Bahadurabad gauging station over a period of three consecutive days is forecasted by the GloFAS model with a maximum 15-day lead time to be more than 50% likely to cross the 1-in-5-year return period.
