Comparison

The comparison provides insight and details related to the methodology and methods applied for estimation of efficiency of low impact development (LID) practices, in order to manage and reduce flood risk in urban areas. The used properties follow the steps of modeling methodologies from top to down (as much as possible). Explanation: Design storm - described by properties design storm, duration of design storm and return period (return periods of design storm applied for analysis); Applied model (modeling procedure, software) - described by models(estimators), model calibration (defines wether some specific method/algorithm/procedure was used to calibrate model), calibrated parameters, performance metrics; Evaluation of LID and drainage design - described by scenarios, LID practices, most efficient LID practice (if LIDs are individually evaluated); and return period of storm (highest return period in the analysis), reduction of peak runoff and reduction of runoff volume for most efficient LID practice or combination (for highest return period used in the analysis); Also, it should be noted: - properties related to hydrological analysis - from catchment area to return period; - properties related to hydraulic analysis - from models (estimators) to performance metrics (performance metrics used for calibration of the model); - combination of LIDs - usually means combination made of LIDs which were previously individually analyzed. In some cases, just the combination of LIDs was evaluated (LIDs combined). So, the properties 'scenarios' and 'LID practices' should be read together to get full meaning of implementation.
