Summary
This study refines the West Java Water Sustainability Index (WJWSI) framework using expert consensus. The Delphi technique and interviews finalized components and indicators, with further study needed for threshold values.
Area of Science:
- Environmental Science
- Water Resource Management
- Sustainability Science
Background:
- The first paper established a conceptual framework for the West Java Water Sustainability Index (WJWSI).
- The framework comprises components, indicators/sub-indicators, and threshold values.
- Refinement of this framework is crucial for practical application.
Purpose of the Study:
- To apply the Delphi technique and in-depth interviews to refine the conceptual WJWSI framework.
- To achieve expert consensus on the components, indicators, and threshold values of the WJWSI.
- To finalize the WJWSI framework for water sustainability assessment in West Java.
Main Methods:
- Utilized the Delphi technique with multiple rounds of questionnaires and data analysis.
- Conducted in-depth interviews with selected key experts from diverse respondent categories.
- Iterative refinement process involving consensus building and expert validation.
Main Results:
- Achieved consensus on all proposed components in Round One, with minor suggested modifications.
- Reached consensus on 9 out of 12 indicators/sub-indicators and proposed 5 new ones.
- Finalized components and indicators through expert interviews; further study is required for unresolved threshold values.
Conclusions:
- The refined WJWSI framework, incorporating expert consensus on components and indicators, is finalized.
- The Delphi technique and expert interviews proved effective in refining the index framework.
- Further research is necessary to establish definitive threshold values for comprehensive water sustainability assessment.

01:19Quality of Water
In concrete preparation, the quality of water is paramount as it affects the strength and durability of the concrete. Potable water is usually preferred; however, it must not have excessive sodium or potassium to prevent compromising the concrete's integrity. Water quality is typically evaluated based on impurities such as dissolved solids, chlorides, and sulfates, and its pH value is ideally between 6 and 8. Even slightly acidic natural water may be acceptable unless it contains harmful...
01:17Design Example: Analyzing Capacity Contours for Flood Risk Assessment
Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...
01:14Testing Water Quality
When the quality of water for concrete preparation is uncertain, its impact on the setting time of cement and compressive strength of mortar is assessed by comparison with de-ionized or distilled water benchmarks. American Society for Testing and Materials (ASTM) C1602 requires the setting times to be within 90 minutes of the control, British Standard (BS) 3146:1980 allows a 30-minute variance in the initial setting, while British Standards European Norm (BS EN) 1008 specifies initial setting...
01:27Design Example: Design of an Irrigation Channel
Trapezoidal channels are widely used in irrigation systems due to their cost-effectiveness and efficiency in conveying water. Trapezoidal channels feature a flat bottom and sloping sides, making them stable and easier to construct compared to other shapes. The bottom width and side slope ratio are determined based on the required flow capacity and site conditions. The side slope is kept gentle for unlined channels to prevent soil erosion.Hydraulic parameters in channel design include the flow...
01:26Design Example: Sustainability in Concrete Building
As the construction industry moves towards more eco-friendly practices, concrete's adaptability and its ability to incorporate sustainable features make it a key material in the drive towards greener building solutions.
There are multiple approaches to achieve sustainability in a commercial concrete building. For instance, construct a concrete parking area under the building, utilizing pervious concrete paver blocks in open areas to facilitate rainwater collection through an underground cistern.

01:28Water Cement Ratio
The water-cement ratio is pivotal in defining concrete's quality. This ratio, a balance between the weight of water and cement in the mix, shapes the concrete's strength, durability, and resistance to environmental factors. As identified by Abrams’ law, less water in the mix equates to stronger concrete. However, water is essential not only for the chemical process of hydration but also for the concrete's workability and compaction. While hydration chemically binds water and cement, physical...
