Hydraulique agricole et aménagement des rivières

Abstract - Agricultural hydraulics and river development
Drainage and irrigation act on transfers between soils and ground water. They have a direct influence, therefore, on rivers both as regards the hydrological regime and the quality of the water.

At present there are methods allowing for the minimization of high water levels from drainage networks. These waters thus transferred can be charged with fertilizer substances, mainly nitrates and also pesticides. An improvement in growing methods enables these risks to be minimized.

Irrigation uses large quantities of water. The installation of connectors, canals, basins, dams comes up against difficulties and may lead to major modifications in the water-flow regime.

The implementation and management of these developments requires more studies and precautions than in the past. The effect on underground water must be taken into account.

Drainage and irrigation increase greatly the productivity and adaptability of agriculture. Now a more refined agriculture enables the quality and the good state of the hydrographic network to be guaranteed at the same time.

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access.

An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.

  • If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
  • You can define your own OpenURL resolver with your EDPS Account.
    In this case your choice will be given priority over that of your library.
  • You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
