<p>Large shallow lakes globally are threatened by eutrophication, and climate change is believed to aggregate the situation. Wind, as the most important momentum source and the major contributor to consistently change the hydrodynamic patterns inside the large shallow lakes, is highly susceptible to climate change. Taihu Lake, which is the 3<sup>rd</sup> largest shallow lake in China and pertains crucial social and economic values, is chosen in this study as an example. Due to climate change, the wind condition of Taihu Lake shows a significantly decreasing trend of wind speed and the frequency of extreme wind events. Previous studies have paid little attention to the climate change effects on wind hydrodynamics and its implications on water quality has not yet been thoroughly described. Here in this study, we use a well-calibrated and validated three-dimensional Delft3D model to investigate the spatial and temporal heterogeneity of wind induced hydrodynamics and its water quality implications with climate change. The model results give a prediction of less current speed, lower wave height and bottom shear stress compared to the reference scenario, while the three dimensionality of flow field remains. Further, water age is used to demonstrate the influence of external nutrient sources, i.e. the input from adjacent river networks in the basin. Large water ages are observed and potentially it would enhance the accumulation of nutrients and deterioration of water quality.</p>

Aims of this Study: To investigate the climate change{effects in Iraq on the quality and quantity of the water of the Tigris River from {Mosul” city to South of Baghdad city.00 This paper provides a review of the observed and the predicted impacts of climate change on the water quality in the Tigris River in Iraq. Study Design: Cross-Sectional study. Place and Duration of Study: The study area is starting {from Mosul city which is located in {the north part of Iraq to the Al-Azziziyah city located in the south of Baghdad (2005-2012) . Methodology: The current study was include the available historical data which are the discharge and hydrochemical analysis includes (Ca, Mg, Na, K, Cl, SO4, HCO3, TDS,NO3, and EC) were taken from 6 stations along the Tigris’ River from Mosul to the south of Baghdad’ cities for the years 2005 to 20112. The available historical climate data’ includes (Rainfall and Temperature) for the period 1990-2012. In this paper also, used some of pervious studies and compared them with the current results. Results: The average annual flow of the Tigris River in Mosul station for the period (1990-2012) ranged between’ (193.8-906) m3/sec and for Sammarra station ranged between’ (366-977) m3/sec. Then, between south of Sammarra’city and north of Baghdad city, Canal of Dijla’joins the Tigris River has a discharge ranges between’ (9-217) m3/sec. After that, the ’Tigris River inter to Baghdad city, the discharge value range between’ (392-1173) m3/sec’and continue his flow to the south of Baghdad city and Diyala River joins it with discharge’range between (55-193) m3/sec. Finally, the Tigris River reaches to’Al-Azizziyah city station with’discharge ranges between (134-769) m3/sec. Conclusion: In general the water quality of the Tigris River are sulfates, calcium, and magnesium. But in Canal of Dijla the most dominant ion is sodium due to agricultural activities and geology of the area consist of gypsum rocks and this can be effects on water quality of Tigris River in the next station (Baghdad). In Al-Azizziyah city the sulfates, calcium, and Sodium is high level due to drainage from irrigation, industrial“and domestic activities.

Phytoplankton Growth Rate

Global climate change induced by increased concentrations of greenhouse gases (especially CO2) is expected to include changes in precipitation, wind speed, incoming solar radiation, and air temperature. These major climate variables directly influence water quality in lakes by altering changes in flow and water temperature balance. High concentration of nutrient enrichment and expected variability of climate can lead to periodic phytoplankton blooms and an alteration of the neutral trophic balance. As a result, dissolved oxygen levels, with low concentrations, can fluctuate widely and algal productivity may reach critical levels. In this work, we will present: 1) recent results of GCMs climate scenarios downscaling project that was held at the University of Derby, UK.; 2) current/future comparative results of a new mathematical lake eutrophication model (LEM) in which output of phytoplankton growth rate and dissolved oxygen will be presented for Suwa lake in Japan as a case study. The model parameters were calibrated for the period of 1973–1983 and validated for the period of 1983–1993. Meterologic, hydrologic, and lake water quality data of 1990 were selected for the assessment analysis. Statistical relationships between seven daily meteorological time series and three airflow indices were used as a means for downscaling daily outputs of Hadley Centre Climate Model (HadCM2SUL) to the station sub-grid scale.
