Abstract: By coupling the standardized precipitation index (SPI), frequently used as a meteorological drought index, with the Tennant concept, popularly used in environmental flow (EF) assessment, this paper attempts to predict the ...

Abstract: The original soil conservation service curve number (SCS-CN) technique is primarily used to transform daily rainfall into surface runoff by assuming the proportionality between retention and surface runoff based on a ...

Abstract: This paper presents a relationship between the runoff curve number (CN) and mean potential evapotranspiration (PET) using long-term daily rainfall-runoff data. To this end, CNs were derived for different durations from ...
