The application of improved flow diverter for first flush management
The paper presents the investigations on first flush phenomenon based on the total suspended solids (TSS) concentration measurement during selected rainfalls at central part of Czestochowa (Poland) and also the hydrodynamic model of the catchment. The model allows to present the conception of first flush management using an improved flow diverter Septurn. Flow diverters used in the separate sewer ...

The influence of rainfall time resolution for urban water quality modelling
The objective of this paper is the definition of a methodology to evaluate the impact of the temporal resolution of rainfall measurements in urban drainage modelling applications. More specifically the effect of the temporal resolution on urban water quality modelling is detected analysing the uncertainty of the response of rainfall–runoff modelling. Analyses have been carried out using ...

Effects of mechanical harvest plus chipping and prescribed fire on Sierran runoff water quality
Received for publication September 14, 2007. Fire suppression in Sierran ecosystems creates a substantial wildfire hazard and may exacerbate nutrient inputs into Lake Tahoe by allowing the buildup of O horizon material, which serves as a source for high N and P concentrations in runoff water. The purpose of this study was to evaluate the effects of biomass reduction using cut-to-length mechanical ...

Exponential data fitting applied to infiltration, hydrograph separation, and variogram fitting
Most lumped rainfall-runoff models separate the interflow and groundwater components from the measured runoff hydrograph in an attempt to model these as hydrologic reservoir units. Similarly, rainfall losses due to infiltration as well as other abstractions are separated from the measured rainfall hyetograph, which are then used as inputs to the various hydrologic reservoir units. This data ...

EVALUATING HSPF IN AN ARID, URBANIZED WATERSHED
The Hydrologic Simulation Program-FORTRAN (HSPF) is a powerful time variable hydrologic model that has rarely been applied in arid environments. Here, the performance of HSPF in southern California was assessed, testing its ability to predict annual volume, daily average flow, and hourly flow. The model was parameterized with eight land use categories and physical watershed characteristics. ...

Spatial and temporal patterns of remotely-sensed and field-measured rainfall in southern California
Quantification of spatial and temporal patterns of rainfall is an important step toward developing regional hydrological models. However, traditionally used rain gauge data are sparse and do not always provide adequate spatial representation of rainfall. In this study, we evaluated the daily 1-degree resolution remotely-sensed atmospheric precipitation data provided by Global Precipitation ...

Pollution wash-off modelling on impervious surfaces: calibration, validation, transposition
ABSTRACTThis paper presents the modification and the application of the conceptual wash-off model initially proposed by the SWMM on five separate urban catchments with very different characteristics and during a lot of rainfall events. To allow measurements on real sites to be considered, this model was incorporated in an overall model including simulation build-up, sediment transport in ...
