Scientific water resources allocation is key to maintaining a healthy Yellow River. GWP China plans to:
1) Influence the rational water resources allocation mechanism and coordinate water rights trading.
2) Set up platforms for dialogue and capacity building between stakeholders and invite research institutions to establish assessment systems.
3) Facilitate agreement on water allocation quotas between the 9 provinces in the Yellow River basin.
The ultimate goal is to contribute to the health of the Yellow River through scientifically set water allocation quotas.

In Hong Kong, studying Geography is categorized as useless because the culture of British Meritocracy here stresses the achievements of business studies. However, if going back to Mainland China or having a travel to either the US or Australia, you will find that your knowledge on Geography is very useful because the ruling regimes there greatly acknowledge the elites who graduated from the field of Agricultural Research.
Cynical people without a longsighted vision use to criticize that my Master Degree of China Studies is something too abstract because they use to be British-Hong Kong colonial debrises. However, they never know that, during my two-year research life in this academic department, I did render some challenging topics including the river-management and dam-construction issues of Mainland China. Just like what Mr. Tung Chee-hwa said in 2014 during a press conference: "Our country is rapidly growing up as a strong economic power. To my greatest disappointment, Hong Kong people still lack a long-sighted vision, and they are unwilling to change their perceptions." So, such group of people will never understand the scholastic efforts I have input in this holistic social-science learning experience.

2018 GIS in Conservation: The Effect of Channel Migration on Riparian Vegetat...GIS in the Rockies
Historically, the South Platte River in Colorado has experienced substantial inter-annual flow variability, but due to water management over the last century, there has been a parallel rise in ground and surface water level consistency. This is problematic for the dominant riparian vegetation of the region, the disturbance-dependent cottonwood, which relies on frequent flood events to clear vegetation to allow for the growth of new trees along the riverbank. Through this research, we attempt to understand the patterns and dynamics of the South Platte River’s riparian vegetation to aid resource management. This research focuses on channel migration dynamics and how these impact adjacent riparian vegetation. To study this, we digitized riparian vegetation using orthophotos at roughly decade increments for a 30 km section of the South Platte in Weld and Morgan counties. We measured changes to riparian vegetation composition and channel locations. Preliminary results show that from 1999 to 2006, a period of overall low flow and drought conditions, this section of river experienced a narrowing of the active channel by 11%. This narrowing was accompanied by an expansion of forest, riparian shrub, and herbaceous vegetation. From 2006 to 2015, a period of time that included high flows and two major flood events, we observed channel expansion of 24%. This was accompanied by decreases in forests, riparian shrubs, and herbaceous cover.

QUALITATIVE ANALYSIS OF WATER LEVEL DEPLETION IN RIVERS PROJECT.pptxArjeetDewangan1
The drinking water crisis in many Indian cities is reaching alarming proportions. Urban population is suffering from irregular water supply, sometimes leading to clashes among them.
The annual rainfall of Iran is about 13% as compared to rainfall in India. Despite of it, due to employing Rainwater Harvesting techniques and better water management , the government of Iran has been able to match up the water demands of the citizens of Iran.The presentations gives an overview of torography,technology, various rainwater harvesting structures employed in Iran.
North Carolina watersheds and river basinsKella Randolph
A river basin is the land that water flows across or under on its way to a river. It is the drainage area of a river. As a bathtub catches all the water that falls within its sides, a river basin sends all the water falling on the surrounding land into a central river and out to an estuary or the sea.
Saltwater is desalinated to produce water suitable for human consumption or irrigation. The by-product of the desalination process is brine. Desalination is used on many seagoing ships and submarines. Most of the modern interest in desalination is focused on cost-effective provision of fresh water for human use. Along with recycled wastewater, it is one of the few rainfall-independent water sources.
• Rainwater is a valuable water resource. Rainwater harvesting has been practiced for more than 4,000 years. In developing countries, it is becoming essential owing to the temporal and spatial variability of rainfall.

IV. Expected Results
It is expected to facilitate
to reach agreement on the
water allocation quota,
involving 9 provinces.
Finally, we can contribute
to maintain the health of
the Yellow river through
scientific water allocation
quota.
The Yellow River is the second-longest river in Asia, following the Yangtze River, and the sixth-longest in the world at the estimated length of 5,464 km. It flows through nine provinces including Qinghai, Gansu, Sichuan, Shaanxi, Ningxia, Inner Mongolia, Shanxi, Henan and Shandong and with a catchment area of about 795,000 km2.
Water resources is the key to the social and economic development as well as the ecosystem protection of the YR Basin. The annual water quantity of the YR is 70.66 billion cubic meters, merely accounting for 2.5% of the total national water quantity.
The Yellow River Basin and its tributaries have been changed owing to climate change and human activities. The ground water of the river basin has been reduced by 11% from 1980 to 2012, comparing with that from 1956-1979.
Its average discharge is around 2,110 cubic meters per second. However, since 1972, it often runs dry before it reaches the sea.
Of total water quantity, the water volume of upstream accounts for 54% and midstream takes 39%. Total sediment load is 1.6 billion tons/year, of which upstream takes 3% and midstream takes 93% as descends from the Loess Plateau. The Yellow River has more sediment but less water.
The downstream of the Yellow River is in the North China Plain. This area has wide flat, slow water flow and the sediment-laden river leads to the river 4 ~ 5 meters higher than both river sides. It has been well known as the suspending river.
The Yellow River is the key source for the water supply to the northwest and northeast of China. Yet, the water volume of the YR only takes 2% of the total national water quantity which feeds the drinking water for the 12% of total national population, 17% of total farmland and 50 cities.
Owing to the influence of natural problem and human behaviors, the YR had been always suffered from disconnection since 1972. The worst year was 1997, this station disconnected for 226 days, influencing 704 kilometers that accounting for 90% of the total runoff on the downstream.
受人类活动和气候变化共同影响,地表水资源量呈逐渐衰减趋势,但经济社会用水量呈增加趋势,黄河入海水量大幅度减少,河流生态环境用水被挤占。
入海水量减少,致使湿地面积萎缩、土地盐碱化加重、生物多样性减少。20世纪90年代,因严重断流,河口地区植被面积减少将近一半,鱼类减少40%,鸟类减少30%。
No enough water for ecosystem, self- cleaning, sediment carrying and channel configuration;
Conflict between social-economic and ecosystem water demand;
Conflict between provinces on the upstream and those on the downstream;
Conflict between trunk and tributaries.
In the past, a healthy river referred to the healthy indicator of river ecosystem, merely from the perspective of Biophysics.
Now, the connotation of a healthy river refers to the balance between interests of human and those of other creatures of the river in the premise of the security of river life. The new connotation presents the integrated demand of society, economy and nature.
Ecological Integration: support, maintain and balance the integrated adaptive ability of ecosystem to the nature.
Rehabilitation: the ability to recover itself from interruption.
Commodity: water supply to industry, agriculture, domestic lives and others.
Services: fish production, drinking water supply, recycle and self-cleaning.
