Authors: Luo Zongbao , He Li 
Published: March 2020

Abstract
The construction of hydropower stations not only improves water conservancy and hydropower generation, but also seriously hinders the natural biogeochemical circulation of rivers, resulting in phosphorus retention in reservoirs, eutrophication of water bodies, and finally phosphorus pollution. Therefore, it is of great significance to study the effect of phosphorus retention in the closure of dams of hydropower stations.In order to solve this problem, this paper, based on the global news model, simulated the retention of phosphorus in eight dams and reservoirs in China.The results showed that :(1) phosphorus production was higher in the densely populated and economically developed basins along the southeast coast of China, among which the phosphorus production was highest in the Yangtze river basin and the pearl river basin, reaching 139 kg/(km2· yr) and 161 kg/(km2· yr), respectively.(2) China’s dams are mainly built in the middle and lower reaches of the Yangtze river, which is closely related to the rich water resources and the developed regional economy.It is worth mentioning that the dams with the highest phosphorus retention are also located on the major rivers of the Yangtze, Yellow and Huai rivers.In general, the areas with high phosphorus retention are mainly concentrated in central and southern China.Population, economy, latitude, area, runoff and other factors will be the key factors to determine phosphorus retention.

Abstract
The characteristics of submerged macrophytes communities, water environment factors and substrate environmental factors of Lake Qionghai wetland were investigated in April 2018 by laying out 21 sample points. A total of 8 submerged macrophytes species were recorded in the 21 sample points. Myriophyllum spicatum, Vallisneria natans, Ceratophyllum demersum, and Potamogeton malaianus were the main submerged macrophytes species in Lake Qionghai wetland. The depth of submerged macrophytes was less than 2m, and submerged plants were found in most areas of lakeside zone. Submerged macrophytes had a strong adaptability to substrate, it could grow in artificial stacked group rocks, natural lakeside stone sand, natural alluvial river sand, loess and silt, etc, but the substrate with high nutrition was more favorable to the growth of submerged macrophytes than the substrate with low nutrition. Water nutrients, bottom nutrients and water depth are the decisive factors affecting the growth of submerged macrophytes, while transparency, chemical oxygen demand, light, temperature, water flow and pH are the decisive factors affecting the survival of submerged macrophytes.

Abstract
In this study, the non-expected output SBM - undependable model was introduced to evaluate the efficiency of waterway transportation in Jiangsu province from 2007 to 2015. The results show that: (1) The evolution of water transport efficiency during the study period is characterized by a small fluctuation in the early stage and a large change in the late stage. Between 2007 and 2012, efficiency values ranged from 0.4 to 0.6, and were at an inefficient and stable stage; Between 2013 and 2015, efficiency values ranged from 0.6 to 1.0 and were in a medium - to high-efficiency fluctuation phase. (2) Through the analysis of the reasons of inefficient transportation in the study period, we can find that there are some phenomena in Jiangsu province, such as redundant input factors, low energy utilization rate and more unexpected output. The efficiency of water transport in Jiangsu province can be improved by optimizing the transport capacity structure, improving energy efficiency and reducing environmental pollution.

Published: March 2020

Abstract
Motion process monitoring is the core component of motion state analysis system and motion safety assurance system. For the water sport, implementation of monitoring is directly related to the safety and security of sportsmen, which is more significant. This paper presents a kind of underwater sports safety monitoring system based on radar idea. The system consists of four parts: video acquisition, image processing, data sample comparison and signal transmission. Reasonable cameras are used to capture the whole swimming pool, and then the motion information parameters of the swimmers are obtained by image segmentation and tracking, and compared with the standard drowning behavior parameters, so as to determine whether the swimmers are drowning or not. If it is judged that a person may be drowning, the system will send out a corresponding rescue signal, which will quickly alert and notify rescuers through the wireless signal transmission system, so as to rescue those who may be drowning, so as to enhance the safety of people’s movement in the water. The drowning behavior is identified by the established drowning feature data sample set, which avoids the occurrence of invisible drowning events that are difficult to detect. By using the high-speed DSP, the data processing and alarm system’s timely response can be realized, which greatly shortens the rescue time, directly improves the survival probability of drowning and reduces the physiological damage. The design of the monitoring system will eventually help the lifeguards to complete the task of underwater movement safety.

Abstract
In order to meet the requirements of data transmission reliability, a geotechnical environment security monitoring system based on wireless sensor network is proposed. The optimization control strategy uses the deadline miss rate as the QoS performance evaluation index. For the data transmission between the sensor node and the coordinator node, the PID controller is used to calculate the network bandwidth requirement of all sensor nodes, and then the system optimal problem is solved to realize the dynamic. The transmission period of the sensor node is adjusted to maintain the deadline miss rate at a normal set level, thereby improving the QoS of the network. Experiments show that the optimized control strategy improves the performance of the system and has good practicability in geotechnical environmental safety monitoring.
