2 Study area Data Objective Results

3 Three Gorges Project The Three Gorges including Qutang Gorge, Wu Gorge and Xiling Gorge, span 193 kilometer from the western-upriver city of Fengjie in Chongqing to Yichang Nanjinguan in Hubei Province.

4 TGR Dam Climate: subtropical monsoon Distribution of counties in the TGR Catchment area: 54,000 km 2 Population: 16.8 million

5 Number of bloom outbreaks CONTENTS Algae Blooms From 2003 to 2012, algal blooms have occurred in more than 20 tributaries, a total number of 197 cases. Duckweeds in Jialing river Blooms in Peng river Blooms in Xiangxi river (a) Cyanobacteria in Zigui Year (b) dinoflagellate green alga Implicit cyanobacteria Month

6 Factors influence algae blooms Slower flow Deeper water Longer residence Less diffusion Temperature Flow velocity (ntu.edu.sg) Light Bloom Species competition Nitrogen Phosphorus etc. Nutritive salt Algae deposition

7 Basic Situation of Reservoir Inundation Since the TGR has reached a sufficient water-level scheduling interval from 145 to 175 meter, creating a 30-meter water-level-fluctuation (WLF) zone 水位 (m) 月份 Month Water Level (m) m 175

32 Summary 1. The overall pollutant loads in Pengxi River basin did not change significantly by comparing 145-meter and 175-meter scenarios, however hru level had been negatively affected by such pollutant inputs locally. 2. Using SWAT to calculate the pollutant loadings in the WLF zone at Pengxi River basin, we provide a reference method of SWAT application in the context of supporting the management and decision-making for the government. 3. Ecological restoration in 30-meter WLF zone is recommended. Results
