a study on thermodynamic models for simulation of 1,3 butadiene purification columns
attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
Uncertainty in Calibrating Flood Propagation Models with Flood Boundaries Derived from Synthetic Aperture Radar Imagery
An instantaneous synthetic aperture radar (SAR) derived flood extent map helps retrieving the distributed conveyance parameters in one-dimensional flood routing models. These models are generally calibrated based on the sole use of ground data. This research aims to use earth observation (EO) data in order to establish a significant parameter retrieval strategy, providing an alternative model c...
متن کاملAsar Derived Flood Maps for Flood Propagation Model Calibration
During flood events Earth Observation (EO) Synthetic Aperture Radar (SAR) is able to provide valuable information on the spatial extent of inundations. With its multi-polarisation capacity, the ENVISAT ASAR instrument is now able to propose reliable data for maximum flood extent retrieval. These extents can be useful in calibrating and/or evaluating flood propagation models and their uncertaint...
متن کاملOn the Use of Global Flood Forecasts and Satellite-Derived Inundation Maps for Flood Monitoring in Data-Sparse Regions
Early flood warning and real-time monitoring systems play a key role in flood risk reduction and disaster response decisions. Global-scale flood forecasting and satellite-based flood detection systems are currently operating, however their reliability for decision making applications needs to be assessed. In this study, we performed comparative evaluations of several operational global flood fo...
متن کاملTowards Operational Flood Mapping with Satellite Sar
Space-borne SAR sensors are of special interest for mapping flood extent due to the possibility to acquire images in all weather conditions. In this article we review the SAR part of an operational flood mapping service. An operational service requires fully automatic methods that are able to process any available SAR data in near-real time. Mapping flood with SAR requires different approaches ...
