Danjiangkou Reservoir and its upstream tributaries as water resource area is of strategic importance for the Mid-route of South-to-North Water Transfer Project. Water conservation and water purification is the key measures for sustainable water diversion. Green water management as a new technologies to achieve water conservation and water purification has a broad application prospects. In this research, green water management was studied in the Upper Du watershed. ArcSWAT model was used to assess quantity of green water resource. By adjusting the model parameters, the efficiency of different green water management scenarios on water and soil conservation were simulated. The results of the study indicate that the quantity of green water in the Upper Du is about 5.588 billion cubic meters. Mulching is a better green water management way that more suitable for water and soil conservation in the Danjiangkou Water Resource Area. This research can provide a reference for water resource protection and management in Water Resource Area of the Mid-route of South-to-North Water Transfer.

Danjiangkou Reservoir and its upstream tributaries as water resource area is of strategic importance for the Mid-route of South-to-North Water Transfer Project. Ecological and water security are the key measures for sustainable water diversion. Green water management as a new technology to achieve water conservation and water purification has a broad application prospects. In this research, green water management such as bench terraces, contour tillage, mulching and stone line was studied in the Upper Du watershed. ArcSWAT model was used to assess effect of green water management on river base flow. The results show that four green water management measures activated the regulating action of “soil water reservoir”. Base flow in export section of Upper Du river basin is increased under different four green water management measures, and especially the base flow increased more obvious in non-flood season. That is helpful to improve the ecological security degree in water resources area.

Taking the Nakau River Basin Governance Project as the research area, the problems existing in the Nakau River Basin, the key and difficult points of water and soil conservation management, and the measures and implementation effects of water and soil conservation in urban rivers are discussed. According to the characteristics of soil and water loss in the inland rivers of the city, an effective prevention and control measure system was proposed, which ultimately effectively prevented human-induced soil and water loss during the construction of the project, protected water and soil resources, guaranteed the safe operation of the main project, and maintained and improved the regional ecology surroundings.

Improving water management in rural towns such as Wagin, Western Australia, will decrease infrastructure damage caused by water and salinity and produce a ‘new water’ resource. The aim of this paper is to predict feedlot water demand using a bioeconomic model, H20Sheep, to determine if using such a ‘new water’ resource could be a viable option for this production system. Wagin (–33.3075 S, 117.3403 E), a township south-east of Perth, was chosen as the specific location for a sheep feedlot producing prime lambs. In this paper, the H20Sheep model was used to show how feedlot returns are influenced by the price of water, different feeding regimens and climate change. This was done by integrating feed and water intake of lambs, general feedlot water use and waste disposal. To show relative sensitivity of changing other model parameters that are not directly connected with water, changes in the purchase and sale price of lambs were also investigated. As might be expected, H20Sheep shows that returns from a sheep feedlot enterprise can be extremely sensitive to changes in lamb purchase (just over 7% increase will result in negative returns) and sale prices (a 4% decrease will generate a negative outcome). With respect to water, the findings indicate that, while increases in water use in the feedlot and price have to be greater than the increase in relative price of sheep, monitoring the biological parameters associated with water as well as water prices is still important both from a management and an economic perspective. Hence, if towns involved in the Rural Towns – Liquid Assets project, such as Wagin, decide to sell their water, the relevant policy makers should ensure that the sale price enables an effective water management system for the town and is also attractive to end-users such as feedlots.

Water And Soil Conservation

Moso bamboo and natural secondary forests are the typical forest types in subtropical area in China. With field observation at the Qiangjiangyuan Forest Ecosystem Research Station. the effect of the two typical forests was compared on soil and water conservation and their difference was quantified. The results showed that: (1) The runoff coefficients for moso bamboo and natural broad-leaved secondary forest go up with increase of precipitation. (2) Natural broad-leaved secondary and moso bamboo forests both are pretty good in preservation of water source and water and soil conservation. The former is better than the latter. moso bamboo forest is over 90% higher than natural broadleaved secondary in runoff generation, and three times higher in sediment yield. (3) Runoff for two forest types has a significant correlation with precipitation outside the forest. Total runoff has a significant linear relation with precipitation, and the runoff coefficient has a logarithm correlation with precipitation.

The disturbance characteristics of power transmission line projects are long distance, scattered disturbances, large differences in natural conditions, and diverse types and strengths of soil erosion. These two points are the key to soil and water conservation, Including that identifying the main controlling factors of soil erosion in each construction disturbance area, and adapting measures to local conditions, and setting up water and soil conservation measures for disasters are power transmission lines in hilly areas. This paper took a specific project as an example, analyzed and evaluated the characteristics of water and soil erosion in the project and optimizes the configuration of measures, in order to provide a reference for the arrangement of water and soil conservation measures in the construction of similar projects.

Abstract Public participation in water conservation projects is gaining more and more attention in the information era. Public opinion, showing the focus and interests of the public, is the basis of public participation. This paper proposes a social sensing system based on social media platforms, which employs two natural language processing technologies, namely, sentiment analysis and topic modeling. The public opinion on water conservation projects is monitored from three perspectives: public opinion intensity (POI) monitoring, topic detection, and sentiment analysis. To test their effectiveness, a case study on the South-to-North Water Transfer Project (SNWTP) in China is conducted. The public opinion data were acquired from Sina Weibo, China's largest social media platform. The results indicate that: (1) POI peaks when hot project-related events occur, and POI of direct stakeholders apparently exceeds indirect stakeholders; (2) different stakeholders have different topics of concern closely associated with their interests; (3) negative events always lead to dramatic decreases in the sentiment value (SV), while positive events only slightly lift SV. The proposed system has achieved real-time monitoring of the public opinion on water conservation projects. Consequently, it can help to improve the level of public participation and provide a valuable reference in project management and policy-making.
