科学领域:
- 环境科学 环境科学
- 水文学的水文学
- 城市规划 城市规划
背景情况:
- 干旱地区的大都市面临着城市化和气候变化加剧的关键供水挑战.
- 德黑兰的水资源紧张正在加剧,地下水供应超过51%的需求,水层每年耗尽32厘米.
- 不可持续的水需求是由人口增长,移民,城市规划不良和环境管理不足所驱动的.
研究的目的:
- 开发和应用先进的机器学习模型,在气候变化和城市压力下预测德黑兰的水资源.
- 评估城市集中,土地利用管理不善和气候变化的对水资源供应的影响.
- 为可持续的水资源管理和在水库和含水层之间分配提供路线图.
主要方法:
- 混合模拟模型结合了循环神经网络 (RNN) 和长短期记忆 (LSTM) 与优化算法 (火优化器,鱼优化算法,马优化算法).
- 在三个排放路径 (SSP1.26,SSP2.45,SSP5.85) 下,利用了三种最先进的气候模型 (MRI-ESM2,CNRM-CM6-1,BCC-CSM2) 进行2021-2050年预测.

Responses to Drought and Flooding
10.5K
Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.

The Water Cycle
23.9K
The Earth’s hydrosphere includes all of the areas where the storage and movement of water occurs. Since water is the basis of all living processes, the cycling of water is extremely important to ecosystem dynamics.

What is Climate?
18.1K
Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.

Adaptations that Reduce Water Loss
25.0K
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: Analyzing Capacity Contours for Flood Risk Assessment
28
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...

Global Climate Change
24.0K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.
