“…The study was performed for 16 streamflow gauging stations in Piranga basin. The results show that the annual Q95 is 31% higher than the Q7.10, whereas the monthly values were statistically equal [12]. According to different study, as a result of the assessment of the contribution of groundwater discharges to rivers using monthly flow statistics and flow seasonality in South Africa, it was found that seasonality has a great effect on groundwater potential [13].…”

The demand for water resources is increasing day by day due to the rapid increase in the world population, drought caused by industrialization, urbanization and global climate change. The efficient use of water resources depends on the correct planning and operation of the water resources systems of the future. The seasonality analysis is to reveal the similarities between the hydrological characteristics of the currents regionally. Examining the seasonality of river flow data is essential for the correct design and efficient operation of the hydraulic structures to be designed. In this study; the seasonal similarity of low and high stream flows throughout the year was determined by using the daily flow data of 5 flow streamflow gauging stations selected at certain geographical points of the Kızılırmak basin. The similarity of the basins was determined by using the seasonal statistics calculated and the direction of the average occurrence dates for each station. This observed similarity was also associated with the hydrological similarity between stations and the hydrological characteristics of the basins were found.

“…This analysis improves the understanding of the hydrological dynamics in the gauges and their potential relationship with water quality. The q7,10 was selected because it is the low flow used by the state of Minas Gerais for water resources management and planning, and it was normalized by the catchment's upstream drainage area to estimate water production, and therefore, allow their comparison [31].…”

“…With regards to the hydrological patterns, which summarize the historical flowrates from 1989 to 2018, it is clear that these are similar: Streamflow increases from November to March and decreases from March to October. In a study developed in the Piranga basin, streamflow regionalization techniques were applied to estimate the water availability variation throughout the network, and it was observed that, in some points of the hydrography, the difference between dry and wet seasons reaches almost 120% [31].…”

Given the nature of E. coli data, characterized by a wide range of values, smaller observations commonly get overwhelmed with larger ones.…”

Although water availability depends both on qualitative and quantitative aspects, most studies focus only on one of these. Therefore, the goal here is to relate water quality and quantity with the construction of Load Duration Curves (LDC) and to estimate E. coli load patterns in different flow conditions, seasons, and positions of two sub-basins of the Doce watershed (Brazil): Piracicaba and Piranga. A novel methodology is proposed in which the Burr XII distribution is adjusted to the LDC to compare all observed loads to their respective Total Maximum Daily Load (TMDL), allowing the estimation of the relative difference (RD) between these. Higher values of RD were observed for low flows for the Piracicaba basin, more urbanized, where point sources of pollution are the primary concern, reaching up to 99% of needed load reduction. In the Piranga basin, more agricultural, there was a broader RD variation, from 9% to 97% load reduction needed, which is an evidence of point sources of pollution combined with non-point sources. The new methodology can be used to estimate the load reduction of any pollutant and can be used by environmental agencies to identify effective practices to minimize and control pollution in different locations of the basins.

“…Diante desse cenário, cresce a necessidade de entendimento da bacia hidrográfica como unidade de gestão (SWAROWSKY et al, 2011;FERREIRA et al, 2017). Os reguladores de bacias hidrográficas precisam alcançar um gerenciamento que suporte da melhor forma as variações hidrológicas dentro de uma bacia, buscando sempre identificar formas de otimizar o uso da água sem impor riscos e conflitos para o seu uso (SERRANO et al, 2020). Para Ferreira et al (2017) relatam que a gestão inadequada de bacias hidrográficas tem ocasionado sérios problemas de disponibilidade de água, tornando-se situações de crise hídrica.…”
