Estimation of Urban Impervious Fraction from Satellite Images and Its Impact on Peak Discharge Entering a Storm Sewer System

Ravagnani, Fabrizio; Pellegrinelli, Alberto; Franchini, … - In: Water Resources Management 23 (2009) 10, pp. 1893-1915

The runoff coefficient in an urban basin is highly influenced by the impervious and pervious surface fractions since they affect the entity of rainwater entering a storm sewer system.

sensed data into a net farm income projection model. Using in-sample regressions, satellite imagery appears to increase …-of-sample framework, the satellite imagery appeared to statistically improve only 8 of the 81 models (9 crop reporting districts by 9 … forecasting horizons) estimated. Moreover, 41 of the 81 models were statistically better without the satellite imagery data. This …
