Flash Flood Risk Management – A Training of Trainers Manual GLOF risk mapping GLOF risk mapping is an important tool to help predict the area likely to be impacted by a GLOF, to estimate the vulnerability of those areas, and to help in the planning mitigation measures. Detailed descriptions of GLOF risk mapping can be found in Shrestha et al. (2006) and Bajracharya et al. (2007a, 2007b). The process involves estimating the discharge hydrograph at the outlet (breach). This can be done using dam break models or by simple calculations assuming the breach size and the lake drawdown rate. The hydrograph is routed through the river reach to find the peak discharge and flood height at the locations of interest. An inundation map is prepared by overlaying the flood height over the terrain map.
Day 4 Briefing for the Field Trip Time: 30 minutes Objectives To share information about the upcoming field trip, including XX the objectives of the trip XX the list of planned activities XX practical information XX tips on required preparation Activities Take some time to properly orient the participants on the upcoming field trip. Make sure to mention the following. • Discuss the objectives of the field trip. • Point out each field visit site on a map, and explain how far it is and the route that will be taken. • Describe the special or unique features of each field site and relate these feature to the success or failure of past flash flood risk management activities. • Describe the activities that the participants are going to observe, and what they are going to do in the field. • Go over the logistics of the field trip: time of departure, time of arrival at different places, length of stay, and what is expected at each site. • Clearly mention any necessary preparation that needs to be made beforehand; list practical items that may be required: comfortable clothing, shoes for trekking, sun glasses, sun block, insect repellent, and other items as needed. Suggestions for the facilitator Preparation A little prior preparation can help to make the field trip a success. Note the following: • If at all possible, visit the sites of the field trip beforehand. • Select places where different flood risk management measures have both been successful and unsuccessful. • Once you have decided on a location, make sure to advise the community in-charge and others that you will be working with that you will be coming and when. • Prepare a short description of the places to be visited, the events or activities to take place there, and any other necessary information such as the distance and the time to get there. • Give a short presentation in which you describe the different places that the group will be visiting and point out what floodrelated points of interest need to observe in each place. • Distribute a copy of the short description of the locations to be visited to each participant after the briefing on the field trip. session 16 (continues) 115
