Application of Build-up and Wash-off Models for an East-Australian Catchment
Estimation of stormwater pollutants is a pre-requisite for the protection and improvement of the aquatic environment and for appropriate management options. The usual practice for the stormwater quality prediction is performed through water quality modeling. However, the accuracy of the prediction by the models depends on the proper estimation of model parameters. This paper presents the estima...
متن کاملEvaluation of the Performance and the Predictive Capacity of Build-Up and Wash-Off Models on Different Temporal Scales
Stormwater quality modeling has arisen as a promising tool to develop mitigation strategies. The aim of this paper is to assess the build-up and wash-off processes and investigate the capacity of several water quality models to accurately simulate and predict the temporal variability of suspended solids concentrations in runoff, based on a long-term data set. A Markov Chain Monte-Carlo (MCMC) t...
متن کاملDevelopment of a Catchment Water Quality Model for Continuous Simulations of Pollutants Build-up and Wash-off
Estimation of runoff water quality parameters is required to determine appropriate water quality management options. Various models are used to estimate runoff water quality parameters. However, most models provide event-based estimates of water quality parameters for specific sites. The work presented in this paper describes the development of a model that continuously simulates the accumulati...
متن کاملAn Investigation of the Relationships between Rainfall Conditions and Pollutant Wash-Off from the Paved Road
Stormwater runoff monitoring was carried out from 2011 to 2015 to investigate the relationships between rainfall conditions (antecedent dry days (ADDs), rainfall intensity, depth and duration), and water quality parameters of stormwater from a paved road in Korea. Factor analysis suggested that the effect of rainfall conditions on the concentrations of selected pollutants varied depending on th...
متن کاملGIS-based influence analysis of geomorphological properties on pollutant wash-off in agricultural area.
This study improves the estimation of the self-purification coefficient for runoff analysis of pollution load using geomorphological factors. Formerly, the assimilative capacity, K, was estimated using a single geomorphological factor, Horton's form ratio, St. Here, K was divided into two factors, namely, a watershed self-purification coefficient (K) and a watershed form ratio (S(f)). The water...
