Assessment of distributed hydrological model performance for simulation of multi-heavy-metal transport in Harrach River, Algeria

Abstract

This paper aims to assess the performance of a distributed hydrological model for simulating the transport of various heavy metals in rivers, to enhance and support environmental monitoring strategies for rivers in developing countries. In this context, we evaluated the performance of the Geophysical flow Circulation (GeoCIRC) model based on Object-Oriented Design (OOD) for the simulation of contamination from multiple heavy metals (Pb, Hg, Cr, and Zn) in Harrach River in Algeria. The results of the case study were in good agreement with the observations. Methodology for the assessment of data quality control and the improvement of monitoring procedures was proposed by using the hydrological model to simulate different scenarios. The GeoCIRC-model-based OOD allowed the prediction of the concentrations of heavy metals with minimal input data. Also, various heavy metals could be numerically treated simultaneously because the OOD increases the model's flexibility to allow the handling of many transportable materials. Therefore, the GeoCIRC model is a powerful tool for the monitoring of environmental contamination in rivers by various heavy metals.

Lattice-Boltzmann-Method-Based Numerical Simulation for Heavy Metal Migration Process during Deep-Sea Mining

“…Horvat et al [11] developed a two-dimensional-numerical-model-suiting approach to simulate the complex flow, sediment transport, and heavy metal transport conditions in natural watercourses. By assessing the performance of the distributed hydrological model for simulating the transport of various heavy metals in rivers, Bouragba et al [12] utilized a hydrological model to numerically calculate the migration of multiple heavy metals, i.e., Pb, Hg, Cr, and Zn, in the Harrach Rivera. Zeng et al [13] studied the dissolution of heavy metals in the mining transportation process and investigated its impact on seawater quality.…”

Application of hydrological model to assess river flow in the transboundary cryosphere and data-scarce watershed, a case study: Chitral-Kabul River Basin (C-KRB) in Pakistan

“…Different hydrological models such as Inverse Laplace Transform Diffusive Flood Routing model (ILTDFR) (Cimorelli et al 2015), Soil and Water Assessment Tool (SWAT) model (Rostamian et al 2008), University of British Columbia (UBC) model (Loukas & Vasiliades 2014) and Snowmelt Runoff Model (SRM) (Tekeli et al 2005) was effectively used for nearly real-time flow monitoring, and flood prediction with respect to its applicability, limitations and aerial or ground data availability. Herein, we have applied HEC-HMS model which has a wide range application in both cryosphere (snow-covered) watershed or no snow-cover watershed (Yusop et al 2007;Stojković& Jacímović2016;Gao et al 2017;Bouragba et al 2019). HEC-HMS model could be applied in both, event-based (Jin et al 2015;Shahid et al 2017) and continues-based modeling (Chu & Steinman 2009;Azmat et al 2017), commutating runoff volume, direct runoff, base and channel flow which includes watershed precipitation and evaporation methods for surface runoff simulations.…”
