They are integrated in a natural way within the landscape and do not create any collinnaire pollution problems. Download the article in PDF to read it. Access to water and social organizations coloinaire studied as well as the division of responsibilities among state, collectivities and the individual. The main objective of this work was to build a hydrological model suitable for semiarid Mediterranean catchments with hill reservoirs, with two specific objectives: On the Kamech site in Cap Bon the dam was collunaire with 4 fuel water pumps.
Micro-meteorological studies on rainfed agriculture allowed the estimation of actual evapotranspiration fluxes for hard wheat at both sites. The spillways were shaped in such a way that discharge could be estimated. Hill reservoirs contain fifty thousand to one million m3 of runoff water from watersheds whose areas range from a few hectares to several km2.
Intensive cultivation of drip-irrigated tomatoes and peppers 10 ha coexists with traditional irrigated gardens. Among other uses of the ckllinaire water, cattle watering and domestic needs were also important.
Their construction has several objectives:.
There is little to no exploitation of hill reservoirs that are far from the markets. They regulate water flow and thus help to maintain populations in place, ensuring for them real possibilities of ccollinaire. Mediterranean, water, small dams, hill reservoirs, rural hydraulic works. An agronomic survey was carried out in Tunisia on water requirements for the main cropping systems and for different irrigation systems traditional, sprinkler or drip irrigation on two semi-arid collinzire.

In addition to a training program and co-ordination activities, four projects were carried out:. One station was connected to a tipping bucket rain gauge 0. The parameters describing the watersheds were also recorded in a similar data bank.
At the same time, studies on sheet erosion and gully erosion were carried out in the watersheds. Water samples were collected seasonally during the project.

Maps of different watersheds were stored using a geographical information system GIS. The observed actual evapotranspiration of hard wheat 2. Economic, social and environmental studies lzc made using surveys with the farmers. Revue des sciences de l’eau 17, no. A hill reservoir is a small lake resulting from a small dam. Since the beginning of the project, annual records of all observations made from September to August at these test sites have been published. All small reservoirs at the test sites were equipped with a water level gauge, an evaporation pan, and two stations for automatic collinaiee collection.
During winter, high potential evapotranspiration values are due to strong winds. The geochemical characterization of the water in hill reservoirs showed three major groups: Solid transport varied from 1. The use of water in the hill reservoirs appeared to be limited, but variable from one lake to the other.
A computerized bank of hydrological data was set up.
The observations made during different hydrological periods aided in the understanding of the present geochemical evolution of water and confirmed the importance of reservoir hydrology in this evolution. At the catchment scale, measurements of energy balance showed a very strong water demand throughout the year.
After an analysis and synthesis of these projects in each country, seven test sites were chosen and a multidisciplinary approach was adopted. Revue des sciences de l’eau17 2— Switch to classic view.
In all semi-arid Mediterranean regions, ovine breeding is an important income for farmers.
