Extreme flooding has become more prevalent due to climate change and has been causing extensive damage, loss of property, and fatalities around the world. Levees are often constructed to prevent inundation in floodplains and urban areas. Flood mitigation efforts during extreme floods include forcing a breach in the levee at a strategic location to avoid flooding at target locations. A well-known example of engineered levee breaches along the Mississippi River is the New Madrid Floodway at Birds Point, controlled by the US Army Corps of Engineers, where a fuse plug design is utilized to detonate a portion of the levee and divert floodwater from the Mississippi River. In our study, laboratory experiments are conducted to investigate the effects of a levee breach opening on the attenuation of the flood hydrograph at upstream and downstream target locations of the engineered breach. The inflow hydrograph is initiated by a computer-controlled valve allowing for various peak discharges and flood durations in the channel. The backwater effect due to the floodplain storage is assessed by adjusting the basin storage volume and the tailwater depth. Flood stage at target locations is recorded using ultrasonic probes. Data obtained from the measurement is analyzed to find the effect of tailwater depth in the floodplain basin on reduction of water depth at target locations.

Evaluation of a Hydro-Meteorological Model System for Flood Forecasting of a Mediterranean Basin in Turkey Kılıçarslan, Berina; Duzenli, Eren; Pilatin, Heves; Yücel, İsmail; Yılmaz, Mustafa Tuğrul (null; 2020-05-08) Floods, which are considered as one of the most destructive extreme weather events, are being more severe issues with changing climate, and they are threatening both human life and property. To address flood hazard issues, this study evaluates the application of a hydro-meteorological model system as an early warning system approach. The Weather Research and Forecasting Hydrological model system (WRF-Hydro), a fully-distributed, multi-physics, multi-scale hydrologic model, has the capability of accurately c...
Sensitivity analysis of 2-D flood inundation model LISFLOOD-FP with respect to spatial resolution and roughness parameter Kıyıcı, Ezgi; Akyürek, Sevda Zuhal; Department of Civil Engineering (2019) One of the most common disasters in the world is flooding and it’s well known that it causes environmental, social and economic damages. Since these damages could be severe and destructive due to drivers such as climate change and humane factors, the necessity of flood management studies is revealed. Europe has recognized the need for creating flood risk maps and flood hazard maps. 1-D and 2-D hydraulic models have been used to obtain these maps. This study is focused on the sensitivity of a 2-D hydraulic m...
Advancement of Satellite Rainfall Applications for Hydrologic Modeling with Emphasis on Flood Monitoring (FLOODSAT) Yılmaz, Koray Kamil(2014-3-31) "Floods are the most widespread and frequent natural disaster responsible for significant loss of lives and property each year. The European Environmental Agency estimated that floods in Europe between 1998 and 2002 caused about 700 deaths, the displacement of about half a million people and at least 25 billion Euros in insured economic losses. As such, one of the four priority areas in FP7 has been identified as triggering factors and forecasting and mitigation strategies for natural hazards. Flood early ...
Overcoming basis risk in agricultural index insurance using crop simulation modeling and satellite crop phenology Hesamı Afshar, Mehdı; Foster, Timothy; P. Higginbottom, Thomas; Parkes, Ben; Hufkens, Koen; Mansabdar, Sanjay; Ceballos, Francisco; Kramer, Berber (2021-04-19) Extreme weather causes substantial damage to livelihoods of smallholder farmers globally and are projected to become more frequent in the coming decades as a result of climate change. Index insurance can theoretically help farmers to adapt and mitigate the risks posed by extreme weather events, providing a financial safety net in the event of crop damage or harvest failure. However, uptake of index insurance in practice has lagged far behind expectations. A key reason is that many existing index insurance p...
Improving the Performance of Index Insurance Using Crop Models and Phenological Monitoring Afshar, Mahdı Hesamı ; Higginbottom, Thomas P.; Parkes, Ben; Hufkens, Koen; Mansabdar, Sanjay; Ceballos, Francisco; Kramer, Berber (2021-03-01) Extreme weather events cause considerable damage to the livelihoods of smallholder farmers globally. Whilst index insurance can help farmers cope with the financial consequences of extreme weather, a major challenge for index insurance is basis risk, where insurance payouts correlate poorly with actual crop losses. We analyse to what extent the use of crop simulation models and crop phenology monitoring can reduce basis risk in index insurance. Using a biophysical process-based crop model (Agricultural Prod...
