📋 Tender Overview
Extreme climate change and natural disasters are posing great challenges for many countries. From tsunamis, floods to sea level rise, these dangers not only rob people but also threaten sustainable development. Facing that fact, many countries have built unique resistance infrastructure models- combining modern technical works and natural-based solutions. Automatic after3current time0: 00/Duration4: 06Auto480p360pautot stars with a sponge city is so promoted- you will understand after watching this illustration! Solving challenges in the management of sponge -pitching water in China in an effort to respond to climate change, urban planning based on nature is becoming a solution that many countries are interested in. In 2013, the Chinese Government launched a sponge city program to solve the challenge in urban water management, encourage the development of green and blue infrastructure (based on nature and water sources) instead of gray infrastructure (concrete, steel). Ecological sponge street is an urban architectural model that simulates the absorption properties of seawater, to restore natural hydrology and water, use 6 functions and water, use 6 functions, water and water, water and water, water, water and water, water and water Rain. This image enhances the permeability of the soil through waterproof sidewalks, urban green coverage and eco -reservoir to delay the peak flood; Combining technology of stored plastic modular rainwater and other solutions; At the same time reuse water after many purification stages such as soil osmosis and artificial wetlands. During drainage, the system combines underground pipes and ground pipes. After filtering, part of the rainwater is reused for irrigation and daily life; The rest is discharged through the urban pipe system, helping to reduce the risk of flooding and limit water pollution. The basic model of the sponge city, when using the porous road surface in the ground. Graphics: Hong Kong Water Supply and Supply Agency at Wuhan - one of the pilot cities - a sponge city model proving that the green infrastructure can deploy quickly, save costs and increase tolerance before climate change. The application of this model helps the city to save nearly 600 million USD compared to the gray infrastructure plan, while bringing many social and environmental benefits such as reducing carbon emissions, improving public health, natural cooling and biodiversity conservation. The Monk Model is currently planning to replicate and adjust flexibly to suit each locality throughout the country. In 2007, the Dutch government launched the Room for the River program with a budget of 2.3 billion euros, deployed in 39 areas in the river space in the 1995 Netherlands, the Netherlands suffered a serious flood, causing 250,000 people to evacuate. Not only rising rivers rise, heavy rains from Germany and Belgium also poured back, causing great pressure causing the dyke system to be overloaded, many land encroachments were submerged. From this incident, the Dutch government realized that it was necessary to change the response strategy. Instead of efforts to push floodwaters to the sea as quickly as possible, the focus was moved to Create more space for the river. In 2007, the Dutch government launched the program Room for the river with a budget of 2.3 billion euros, deployed in 39 areas. The solution includes: Lowering flooded plains, opening water buffers, relocating dikes, digging auxiliary canals and building a new flood drainage route. The objective is to restore natural low -lying areas in places with less damage, thereby protecting key areas. Ha Lan also actively acquires agricultural land subsidence at market prices, transformed into flood storage areas. The plan aims to help the Rhine river can discharge up to 16,000 m3/second without causing flooding. Experts simultaneously calculate the needs of additional space in the context of climate change, ensuring long -term response. According to Professor Maarten Kleinhans (Utrecht University), thanks to this approach, the risk of rivers in the Netherlands has decreased from 1 time/100 years to 1 time/1,250 years. By 2050, the country is expected to spend 90,000 hectares of land to expand the riverit, creating a temporary flooded area to reduce risks and bring sustainable benefits. Not stop there, the Netherlands also develops the model of living with floods: building houses and floating cities. Some projects are designed so that when flooded will turn into a swimming pool; commercial center floating thanks to the buoy system; The solar area provides electricity for the whole city in the flood season ... Marina Barrage is a testament to the integrated urban solution: Water supply - Flood control - Improving the quality of life 3 -in -1 water in Singaporemarina Barrage is the first dam in the heart of Singapore, built on Marina channel 350 m wide, creating Marina reservoir with an areavirtual country). This is Singapores 15th freshwater reservoir. With the idea of 3 in 1, the project serves 3 goals. Firstly, it is a fresh water source: 9 doors to open and close the river water to the sea, turn the Marina into a natural rainwater lake, currently meeting about 10% of the countrys water demand. Secondly, flood control and tidal: The dam acts as a tide barrier, protecting low -lying areas such as Chinatown, Boat Ray, Jalan Besar, Geylang. The system consists of 9 exhaust doors and 7 huge pumps that can pump the amount of water equivalent to an Olympic swimming pool per minute, flexibly discharged water into the sea at low tide or pump at high tide. Third, community space - entertainment: Lake Marina becomes a destination for many activities: rowing dragon boat, community event ... Thanks to the control of water levels all year round, lake maintains the landscape and the environment in the environment. It is a testament to the integrated urban solution: water supply - flood control - improving the quality of life. The project
