Channel Bar

Channel bars are essential landforms and their evolution is crucial to aquatic and riparian biodiversity, river’s water-sediment process, and economic development. With the development of water conservation facilities and hydropower projects, numerous changes have been taken place in hydrological regimes and morphology. There have been many changes on channel bars in the middle reaches of Hanjiang River due to the combined effects of cascade reservoirs. However, little was known about such dynamics and their linkages to cascade dams across the entire downstream area. Using Landsat remote sensing images from 1986–2018 and the threshold binary Otsu extraction method, this study completed comprehensive monitoring of nine mid-channel bars (DX1–DX7, XZ1, and XZ2), and three shoal group (XZ3–XZ5) dynamics. Results showed that the mid-channel bars’ area in the reach from Danjiangkou to Xiangyang (DX) decreased over the past 33 years, with the exception of DX4, while the total area decreased by 23.19%, this channel bars’ area change was mainly influenced by backwater from the Cuijiaying Reservoir with high water level after 2010 (r = −0.93, p < 0.01). The total channel bar area from Xiangyang to Huangzhuang (XZ) decreased by 16.63% from 1986 to 2018. The total channel bar area in XZ had a strong negative correlation with runoff at Huangzhuang hydrologic station (r = −0.79, p < 0.05), which was partly attributed to upstream precipitation according to the high correlation between runoff and precipitation (R2 = 0.65). In general, the DX section was under equilibrium between scouring and deposition compared to downstream Xiangyang, the bars in DX section were mainly affected by water level, and bars in XZ section during 1986–2018 were complicated because it was upstream eroded and downstream deposited. In addition, vegetation cover, revetments, flood events, sand mining, land use, and over-exploitation may cause channel bar area dynamics. Hence, more continuous investigations are suggested to focus on effects of cascade reservoir operation on hydrological regime, as well as the changing morphology of channel bars in the middle reaches of the Hanjiang River.

The San Pedro River has been impacted by continued growth of Fort Huachuca Military Base. The San Pedro River, a riparian-migratory area, has had continuous water flow but now has intermittent water flow. The cause is cones of depression in the aquifer due to domestic well pumping. The aquifer is recharge with water from the river. Cooperative Extension has implemented Resource Conservation Audits for landowners in the lower San Pedro Valley. Also, outdoor classrooms are being constructed at three schools to educate children and community members. The goal of these programs is to educate landowners on water conservation through the use of native and adapted drought-tolerant plants, xeriscaping, irrigation efficiency, water harvesting, soil erosion, and composting. Site visits help landowners identify opportunities to reduce water use. Research-based informational brochures have been produced so landowners can plan and implement water-saving techniques on their properties. This program has been implemented using six members of the Border Volunteer Corp., part of Americorp program.

Variable Rate Irrigation

Abstract. Site-specific variable-rate irrigation (VRI) systems can be used to spatially manage irrigation within sub-field-sized zones and optimize spatial water use efficiency. The goal of the research is to provide farmers and consultants a tool to evaluate the potential benefits of implementing VRI. The specific objective of this research is to evaluate the potential water savings using VRI management compared with uniform irrigation management to maintain soil water holding capacity above 50% depletion using two irrigation scenarios: 1) a standard 12.5 mm irrigation per application; and 2) an application to refill the soil profile to field capacity. A 21-year simulation study was carried out on a selected field with varying degrees of soil and topographic variability. The simulated field had 12 soil mapping units with water holding capacities in the top 0.30-m ranging from 42 to 70 mm. The 21-year simulation covering all weather conditions for each soil produced only two significantly different irrigation management zones for scenario 1, and for scenario 2 only one management zone. However, when the 21-year period was divided into periods with different ratios of rainfall to reference evapotranspiration, the simulations identified 1 to 5 management zones with significantly different irrigation requirements. These results indicate that variable rate irrigation system design and management should not be solely based on long term average weather conditions. Years with differing weather conditions should be used for potentially identifying management zones for VRI systems. Irrigation application depths between management zones ranged from 17 to 38 mm. However, when the actual soil areas of the study field were utilized to calculate the total volume of irrigation water applied, it resulted in an increase in water usage in the 2 and 4 management zones ranging from -1.2% to 5.8%. Water usage with VRI over uniform irrigation was greater by -1.6% to 6.8% in the 12.5 mm irrigations and by -1.2% to 2.2% for the field capacity irrigations Keywords: Management zones, Precision farming, Variable-rate irrigation, Water conservation.

Telkom University makes efforts in developing higher education facilities and capacities by constructing new campus buildings. One of the supports for improving services is sanitation infrastructure in the form of installations consisting of clean water installations, wastewater installations and ventilation, and rainwater installations with the concept of installed clean water. Each building that will be built in the area of West Java Province applies the concept of green buildings and conservation air as regulated in the Regional Regulation of West Java Province 13 of 2013 concerning Buildings, including campus building builders so that business actors are required to implement water management which aims to maintain quality, quantity, and continuity of clean water in West Java Province. The implementation of the installation with the concept of green buildings and air conservation is carried out at the Telkom University Landmark Tower building, which aims to use clean water in the building which can be more efficient because the location of the building is in a clean water distress zone based on the basin map of West Bandung Regency. The implementation of water conservation that is planned is WAC-3 waste water recycling (water recycling) which can be used as a rinse and watering the garden. Construction of infiltration wells which functions to reduce rainwater runoff and increase groundwater reserves, WAC-5 rainwater storage (rainwater storage) which can be used as alternative raw water. The use of the WAC-2 water-saving sanitary device (water feature) uses water usage and PDAM water costs. The application of air conservation that ignores water is 17.5% in the dry season and 61.5% in the rainy season of the clean water need total.

Water Vulnerability

Assessing and mitigating the water footprint of a business can reduce the risks associated with potential freshwater shortages. Because water is vital in the supply chain and operations of all major industries, depletion of freshwater sources, increases in demand of water, and droughts can threaten a company’s production, financial stability, and reputation. Consequently, it is essential to identify water vulnerability in a business’s operational portfolio and to ensure that the business’s water management aligns with its overall sustainability strategies. Furthermore, understanding a business’s water footprint allows for effective resource management, which can help minimize costs and reduce its environmental impact. Currently, interest in the water footprints of organizations, products, and services is increasing, creating a need for a shared standard of definitions and methodologies for water metering and reporting. In addition, consistent methodologies for including embedded and indirect water use and a uniform application of analysis boundaries need to be developed. This research aims to develop an accounting methodology for water reporting along with tools for identifying opportunities to improve water efficiency. Additionally, existing definitions, approaches, and best practices for measuring, reporting, and managing water use across different industries are summarized. A conceptual model was developed to evaluate the lifecycle water footprint, including direct and indirect (embedded in energy and materials) water use in both supply chains and operations. Further, a case study is considered to assess the water impact of a mixed-use facility in Palo, Alto, California. Comprehensive water, electricity, and gas metering data were collected for this site, and the water uses of California’s energy mix were determined. Finally, this data set was utilized to summarize direct and indirect water use at a corporate site, and recommendations of water conservation and reuse for this site are considered. Future work includes development of validation and optimization approaches for minimizing water usage. The model was built such that it can be expanded to include multiple sites in the global supply chain in order to estimate worldwide water usage throughout a large company’s operations.

Purpose Water conservationists have been promoting a hierarchy of measures to preserve water resources in the face of decreasing freshwater availability in the world. However, applicability of water hierarchy to the construction industry is yet to be investigated. To fill this knowledge gap, the purpose of this paper is to investigate water usage, water use efficiency, and conservation measures relevant to the construction operations. Design/methodology/approach A triangulation-based mixed-methods approach was adopted for the collection and analysis of data. First, four case studies were carried out to explore the current practices and the possibilities of applying the water hierarchy to the construction operations. This was followed by a questionnaire survey, administered among construction professionals to obtain their views and to verify the findings of case studies. Findings Strategies such as reuse and recycling were found to be less applicable and least preferred by the construction professionals compared to reduce, replace, and eliminate. Based on the research findings, three enabling measures, namely, regulation, responsibility, and reward, were found to enhance the effectiveness of these conservation strategies. Practical implications Knowledge on preferences of different water conservation measures among the construction professionals and their effectiveness on construction site could help the construction companies to device strategies to mitigate water wastage and enhance water use efficiency. It could also help policy-makers to develop guidelines that would have higher probability of acceptance among construction stakeholders. Originality/value The study proposes an extended water hierarchy (3R.6R) by integrating three enabling measures discussed above for the construction project sites.
