It would be important to develop water legislation and regulations to manage competing water demands at the river basin, catchment, aquifer and local levels.

(2) In particular they shall agree upon monitoring points, river quality characteristics and pollution parameters regularly to be evaluated for the Danube River with a sufficient frequency taking into account the ecological and hydrological character of the watercourse concerned as well as typical emissions of pollutants discharged within the respective catchment area.

And you can notice they have created a kind of false catchment.

a) the study of water cycles and the investigation of each catchment area,

UNEP, through GRID Arendal, is continuing to maintain the Baltic Sea catchment area database.

In addition, Shennongjia forms the watershed between the Yangtze River and the Han River, and covers a total of four water systems, namely, Xiangxi River, Yandu River, Nanhe River and Duhe River.

Effective management links land and water uses across the whole of a catchment area or groundwater aquifer.

UNEP, through GRID Arendal, is continuing to refine the GIS database of the Baltic Sea catchment area.

By the river? Yes... by the river.

The Black river finds the Solimoes river

You can notice the small holes the water will fall on this catchment, and there is a slope.

Red River Six. Come in, Red River Six.

Red River Six, this is Red River Two.

Baima River, the laowanfu River and Beidaliu River and other feeder routes adopt pure market operation.

We then dug a big hole to put in a rainwater catchment tank to take our yard water independent.

c) the conservation of forested and other catchment areas and the coordination and planning of water resources development projects,

For hospital services that require larger catchment populations than present in one county an intercounty market has been established.

Moreover they shall endeavour to contribute to reducing the pollution loads of the Black Sea from sources in the catchment area.

Due to the rainstorm, the river water surged over the river banks.

(b) Develop water management plans in transboundary, national and or local contexts, preferably on the basis of catchment areas or groundwater aquifers.

UNEP, through its GRID facility at Arendal, will continue to develop and refine a GIS database of the Baltic Sea catchment area.
