“…This application would fulfill a gap noticed in river-reservoir integrated studies: the lack of a specific model that includes both environments and properly considers temporal changes. An example of a study focused on water quality along river-reservoir systems was proposed by Tercini & Méllo Júnior (2016), who applied the one-dimensional Streeter-Phelps equations in order to model Biochemical Oxygen Demand and Dissolved Oxygen concentrations along a Brazilian river. This model indicated the critical location for the dissolved oxygen.…”

Water quality models are often applied to support the definitions for water resources planning and management. This process requires appropriate data to calibrate and make the required verification process for validation analysis. However, in some case studies, there is not enough data to run a complex water quality model whatever is the water system, being river or reservoir. In the context of scarce data, the search for a simple water quality model is an alternative to comprehend the water quality behavior of the water system. In this research, an unsteady zero-dimensional (0D) water quality model was developed and applied using synthetic series of phosphorus concentrations for a Brazilian reservoir. The results of the zero-dimensional models developed in this research were compared to the results of a three-dimensional water quality model, in order to verify if this methodology can be a simpler alternative to a complex three-dimensional model. The compatible results of the zero-dimensional (0D) and three-dimensional (3D) models show the simplified numerical schemes are important potential tools to be considered for initial analysis of water quality dynamics in reservoirs and for management purposes.

“…A validação do modelo desenvolvido (Equação 2) foi realizada utilizando-se os dados de coletas de Tercini et al (2016) e Tercini (2014). Os autores avaliaram a autodepuração do rio Tietê desde o município de Pirapora até Salto, no estado de São Paulo, através de uma adaptação do modelo de Streeter & Phelps.…”

“…Considerando o modelo proposto neste estudo, avalia-se a autodepuração do trecho do rio Tietê, adotando os dados de entrada de DBO, que representam o ingresso de carbono, e OD a jusante e a montante do reservatório Rasgão estudado por Tercini et al (2016). Assim, pudemos analisar se o que foi depurado na saída do reservatório coincide com o resultado predito pelo modelo.…”

This study introduces an integrated model for water resources planning and management that accounts for both the quantity and quality of water in watersheds and reservoirs. Therefore, it provides a comprehensive approach for better understanding and assessing water systems. The model facilitates analyses of the spatial and temporal dynamics of hydrological processes, pollutant transport, and the behavior of rivers and reservoirs. The study evaluated pollutant load transport in the Upper Paranapanema Basin by applying the Soil Moisture Accounting Procedure (SMAP) model, Muskingum method, Streeter-Phelps buildup/washoff model, and zero-dimensional (0D) models to estimate inflows to the Jurumirim reservoir. A Python-based public library was developed to model all hydrological processes. The model calibration yielded a NSE, KGE, PBIAS and RMSE result of 0.746, 0.778, 6.5% and 73.3 m 3 s − 1, respectively. Indicating a robust simulation that attests to the versatility and reliability of the proposed approach. The methodology outlined in this research enables comprehensive water quality simulation at basin scale, thereby serving as a tool for understanding water quantity and quality dynamics and support decision-making regarding water resource planning and management.
