“…Q95, Q185, Q275, and Q355 from FDC indicate the criteria for averaged-wet flow, normal flow, low flow, and drought flow, respectively [42]. This study separated FDC into five sections based on the flow indices in an attempt to compare the model performances during low-flow and high-flow separately.…”

Faulty field sensors cause unreliability in the observed data that needed to calibrate and assess hydrology models. However, it is illogical to ignore abnormal or missing values if there are limited data available. This study addressed this problem by applying data imputation to replace incorrect values and recover missing streamflow information in the dataset of the Samho gauging station at Taehwa River (TR), Korea from 2004 to 2006. Soil and Water Assessment Tool (SWAT) and two machine learning techniques, Artificial Neural Network (ANN) and Self Organizing Map (SOM), were employed to estimate streamflow using reasonable flow datasets of Samho station from 2004 to 2009. The machine learning models were generally better at capturing high flows, while SWAT was better at simulating low flows.

“…Among the one-dimensional models for hydraulic and aquatic habitat simulations, the PHABSIM (Physical Habitat Simulation System) is optimal (MILHOUS et al, 1989), as it is widely used in ecohydrologic studies worldwide (AYLLÓN et al, 2012a;LEE et al, 2010, GARD, 2009.…”

One- And Two-Dimensional Ecohydraulic Modeling of Formoso River (Mg)

ABSTRACT:The objective of this study was to compare ecohydrological simulations from a onedimensional model (PHABSIM -Physical Habitat Simulation System) and a two-dimensional model (River2D) in order to indicate a reliable tool that could be used to determine public policies for the sustainable management of the water resources of the Formoso River basin (MG). The results from the calibration of hydraulic variables, namely, water depth and velocity, as well as habitat predictions for three fish species of the river were compared. The results showed that River2D was best suited to simulate ecohydrological features for the studied river stretch. Although PHABSIM presented a better fit of the hydraulic variables at the calibration process, the use of only three monitoring cross sections to compose the biotic model database compromised its habitat modeling. PHABSIM model was not able to accurately assess the actual characteristics of the physical habitat in the segments of the river located between the monitoring cross sections.

“…To create suitable physical habitats for fish in an urban river, target species that are predominant in the river should be reviewed, and their ecological characteristics should be carefully examined first (Lee et al, 2010). Grass carps (Ctenopharyngodonidella), silver carps (Hypophthalmichthysmolitrix), bighead carps (Hypophthalmichthysnobilis) and black carps (Mylopharyngodonpiceus) are known as the "Four Domesticated Fish" in China and these four fish species were selected as the target species because they represent the major fish population of the Jiyun River.…”
