“…Several studies have investigated the impact of climate change on river water quality [38][39][40]. Evaluation of long-term changes in river water quality can help identify the most important factors affecting water quality as a suitable method for determining any environmental changes over time [22,41]. Many other studies have focused on the effect of temperature rise on water quality [42][43][44][45][46].…”

This paper aims to investigate the effects of natural variables, including precipitation and flow rate, on the quality of the Zarjoub River in Guilan province, Iran. The new hydrological insight in this study is a lack of national research focused on the dual effects of rainfall and flow rate on river water quality in coastal areas along the Anzali Wetland. To investigate the effect of precipitation and flow rate on river water quality, nine water quality variables were monitored during the 10-year period. In this article, (a) the existence of trends and the best fitted models of water quality parameters and the discharge and precipitation were analysed using statistical techniques and (b) the relationships between concentration of constituents with the discharge and precipitation on the up-stream and middle station were also examined. Box plots, for explaining the distribution of a data collection, were used. The results showed the existence of trend of water quality parameters with river flow and rainfall. As presented in Section 3, with increasing precipitation and flow rate, concentration of all constituents, except pH and SO₄2, decreased. On the contrary, the maximum amount of water quality elements was observed in low precipitations; therefore, the maximum concentration occurred in less than 15 mm precipitation. Simple regression was used to evaluate the discharge concentration and precipitation concentration. According to the correlation coefficient (r), the relationship between concentration and precipitation is weaker than (0.238) discharge concentration (0.699). The results further showed climate change and river water quality to be related.

Executive SummaryWhile many estuaries in the northeastern U.S. are highly urbanized, such as Barnegat Bay, we do not understand the implications of urbanization on estuaries and especially for economically and ecologically important macrofauna such as fishes and crabs. The long term goal of this project is to determine how the macrofauna respond to urbanization by comparing the temporal (annual, seasonal) and spatial (among and within locations along the north-south gradient that vary in the extent of urbanization) variation in the Bay. During Years One, Two, and Three we sampled extensively at a variety of habitats (marsh creeks, submerged aquatic vegetation, open bay) with a variety of gears (plankton nets, otter trawls, gill nets) that allowed collection of most life-history stages (larvae, juveniles, adults) of representative fishes and crabs. In all 3 years the macrofauna was highly seasonal with abundance greatest in the summer across all habitats (submerged aquatic variation, marsh creeks, open bay). Variation in fish and juvenile blue crab abundance occurred across years with reduced numbers (but not species) during 2013 relative to 2012, but with highest values in 2014. These overall values were also correlated with macroalgae abundance. This variation might have been due to effects of Hurricane Sandy (Fall 2012) but the differences observed are difficult to separate from natural, year-to-year variation for lack of a longer time series that does not in which hurricanes did not make landafall here. Current work in the adjacent and connected estuary, the Mullica River/Great Bay estuary, by graduate student Katherine Nickerson examines a 24 year time series of juvenile fish collections to parse climate and event-related signals from other sources and, on completion, may be helpful in interpreting variation within Barnegat Bay. However, comparisons with similar sampling gear (otter trawl) from early (late 1970s/ early 1980s) and late (2012/2013) indicated that the fish fauna had changed. The fish faunal response over these decades suggest that some resident and cool-water migrant species (e.g. silver hake Merluccius bilinearis) are less abundant and have been replaced by warm-water migrants (e.g. northern kingfish Menticirrhus saxatilis, black drum Pogonias cromis). A prime example of a warm water migrant that is now so abundant that it is harvested in commercial and recreational fisheries is Atlantic croaker (Micropogonias undulatus).
