Characterizing Density Flow Regimes of Three Rivers with Different Physicochemical Properties in a Run-Of-The-River Reservoir

Abstract: Inflow mixing affects the spatiotemporal heterogeneity of water quality in reservoirs. Reservoir water quality management requires accurate prediction of density flow regimes to understand the spatiotemporal distribution of dissolved and particulate nutrients and organics. This study aims to characterize the mixing and circulation of three rivers with different physicochemical properties in a run-of-the-river (ROR) reservoir, using high-frequency monitoring and three-dimensional (3D) hydrodynamic modeling.

“…Previous applications of ELCOM are widely referenced in limnological studies (Trolle et al, 2012), including studies of reservoir hydrodynamics and sediment transport (Dissanayake et al, 2019;Trolle et al, 2012). AEM3D features in more recent publications describing reservoir and lake modeling (e.g., Madani et al, 2020;Ryu et al, 2020;Tranmer et al, 2018;Valipour et al, 2019;Valerio et al, 2019;Zamani & Koch, 2020). Zamani and Koch (2020) demonstrate the appropriateness of AEM3D for modeling reservoirs, such as Upper Yarra reservoir, that have complex bathymetry, steep walls, and a wind-mixed surface layer.…”

“…The XXB was represented by 64 longitudinal segments, each 500 m in length, and 109 vertical layers, each 1 m thick [1,4]. CE-QUAL-W2 has several coe cients that can be adjusted in the calibration process [17,18,19,20,21]. Model performance was evaluated by the absolute mean error (AME) and the root mean square error (RMSE) statistics.…”

“…In ow exhibited plunge ow before the curtain weir location and later travel as inter ow under curtain with different heights such as 3 m, 5 m and 7 m below the water surface [4,7,14,15,18]. The dilution rate of the surface layer increases with the curtain weir height and enhanced the submergence inter ow [4,7,13,14,16,17,19,20,21]. The submergence level of inter ow should be interrupted because the curtain weirs have different heights and locations including upstream, midstream and downstream, corresponding to XX09, XX06 and XX01, respectively Figure.…”
