Abstract
Coronavirus disease 2019 (COVID-19) ascertained as a global pandemic that hit most countries during the first quarter (FQ) of 2020, and lockdown (LKD) has been enforced at different levels to cope with the situation, and most of the industrial and commercial activities were halted during this period. Hence, the present study has been introduced to assess the impact of the COVID-19 LKD coupled with seasonal variations (SVs) on the water quality status of the Hindon River (HR), Ghaziabad (GZB). The report includes secondary data analysis of different water quality parameters (WQPs), viz., dissolved oxygen (DO), biochemical oxygen demand (BOD), fecal coliform (FC), and total coliform (TC). BOD and DO are the preliminary indicators of organic load, and analysis of FC and TC determines the overall pathogen load in water bodies. The effect of seasonal variations, i.e., pre-monsoon (PRM), monsoon (MS), and post-monsoon (POM) at sampling locations designated by the monitoring body at HR (GZB stretch), viz., Mohan Nagar road bridge (MNRB), Karheda village (KV), and Chijarsi bridge (CB) was investigated for 2019 to 2021. DO level was comparatively higher during 2020 at sampling stations (SLSs) MNRB and KV. BOD reductions were ~17–40% during the LKD phase at SLSs KV and CB compared to PRD and PLD. The SVs significantly influence the DO and BOD at all the SLSs. The water samples during the PRM of 2020 showed lower BOD levels compared to 2019 and 2021 at all the SLSs. FC/TC ratio was highest at the LKD phase at all the SLSs. The coliform load was greater at SLS CB than at MNRB and KV. A strong positive correlation was obtained between TC-BOD and FC-BOD at the LKD phase during all the SVs. Based on the WQPs analysis, CB was found to be the most contaminated sampling location. Despite higher coliform loads, the LKD phase experienced overall improvements in DO and BOD levels.

Abstract
This research aimed to investigate the effect of geological and geomorphological factors on the water quality of Gotvand Dam in Iran. Given the role of geomorphological parameters in water quality, the water quality indices were analyzed in the Excel and Chemistry applications. Water quality was evaluated by analyzing water samples obtained from the Statistical Data Center of Water and Power Organization of Khuzestan, and the total dissolved solids (TDS), electrical conductivity (EC), and pH of water were measured using the Mann-Kendall test. Then the effect of geomorphological factors on the physicochemical properties of the Karun River was assessed. The qualitative variables were pH, EC, and TDS in the statistical period of 2006–2021. The results of the Mann-Kendall test showed an insignificant decreasing trend in the TDS series in the Gotvand station. Meanwhile, August had a significant increasing trend in TDS, and considering the calculated Sen’s slope, this parameter increased by 35% in the last 15 years (2006–2021). Like TDS, EC had both increasing and decreasing trends of changes. On the monthly scale, pH had a significant decreasing trend, meaning that the water is acidified, which severely affects the downstream fields and reservoirs. In the Gotvand station, the trend of changes in TDS and EC increased in 11 and 12 months of the year, respectively.
