概括
蓝绿基础设施 (BGI) 降低了洪水风险,但增加了家庭用水需求. 即使是适度的BGI也需要大量的雨水储存,以抵消干旱期间更高的蒸发转化.
科学领域:
- 环境科学 环境科学
- 城市规划 城市规划
- 水文学 水文学
背景情况:
- 蓝绿基础设施 (BGI) 是家庭雨水管理和降低洪水风险的关键策略.
- 在BGI系统中增加的绿色可以导致由于蒸发转化而导致更高的水需求,特别是在干旱期间.
研究的目的:
- 根据荷兰未来气候预测,评估各种BGI类型对家庭水平衡的影响.
- 量化不同BGI配置的额外水需求和所需的雨水收集能力.
主要方法:
- 在100平方米的家庭用地块上模拟14种常见的BGI类型,从"灰色" (没有BGI) 到"最绿色" (密集绿色屋顶,立面,果园).
- 家庭水平衡模拟,考虑气候预测和BGI诱导的蒸发透气.
- 计算满足预计额外用水需求的80%所需的雨水储容量.
主要成果:
- "最绿色"的BGI选项使每日用水需求增加了154.3升,超过了典型的室内用水量.
- 中间的BGI设置 (本土植物或草园) 仅需要8.4-9.9升/天的额外水.
- 为了满足80%的中间设置需求,最多需要2.3立方米的雨水储存,而"最绿色"选项需要14.9立方米的雨水储存.
结论:
- 强化家庭绿化显著影响水平衡,可能会增加供应能力之外的需求.
- 增加绿色空间与适当的收集水系统之间的平衡对于可持续的BGI实施至关重要.
- 仔细选择BGI类型和适当的雨水储存是必要的,以管理干旱条件下的水需求.

Design Example: Analyzing Capacity Contours for Flood Risk Assessment
105
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...

Adaptations that Reduce Water Loss
26.3K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

Design Example: Designing a Residential Plumbing System
790
The design of residential plumbing systems requires carefully evaluating water demand, flow rates, and pressure dynamics to ensure both efficiency and reliability. The nature of water flow within pipes is defined by its Reynolds number, which classifies flow as either laminar (smooth) or turbulent.

Quality of Water
194
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...

Design Example: Design of an Irrigation Channel
227
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...
