Using the HSPF and SWMM Models in a High Pervious Watershed and Estimating Their Parameter Sensitivity

Abstract: Models are necessary tools for watershed management. However, applying watershed models is time consuming and requires technical knowledge, including model selection and validation. The objective of this study is to assess two commonly used watershed models and their parameter sensitivity to reduce model loadings and to gain a better understanding of the model performances. The Hydrological Simulation Program-Fortran (HSPF) model and Storm Water Management Model (SWMM) were applied to a mostly forested Taiwane… Show more

“…To be more exact, a sensitivity analysis is essential in order to explore and quantify the influence of possible changes in boundary conditions on model output and system performance indices (Hall et al 2009;Wang et al 2019). As a result, analysts gain a better idea of the sensitivity of the model to input parameters, and thus can find out how the outputs depend on the certain inputs (Whitehead & Young 1979;Tsai et al 2017;Xu et al 2019).…”

“…The details of the SWMM can be found in the manual [15] and are not explained in this study. The major reason for choosing this model is that the SWMM is widely used in Taiwanese reservoirs, such as the Feitsui reservoir [11,16], Shiman reservoir [12], and Mingde reservoir [17]. Although the SWMM was originally developed for urban drainage system design, its applications were expanded through several revisions and were approved as a watershed model to assess NPS pollution.…”

“…Consequently, they negatively affect the aquatic environment of the receiving waters. Various mathematical models are currently developed in order to predict negative stormwater impacts on the natural environment [1][2][3]. They are useful when making decisions, in adherence to sustainable development principles, which concern land use and urban space management.…”

“…To predict stormwater quality, these models primarily take into account deposition of pollutants on surfaces [1], their runoff, and transportation by the drainage system. The Stormwater Management Model (SWMM) software is commonly used; however, simplifications [2] adopted in the model can make it difficult to fit simulation results to measurements. Literature overview [4] shows that, in many cases, unsatisfactory prediction results can be caused by the simplified model of pollutant deposition.…”
