The geochemical characterization of the water in hill reservoirs showed three major groups: Access to water and social organizations were studied as well as the division of responsibilities among state, collectivities and the individual. The spillways were shaped in such a way that discharge could be estimated.
On the Kamech site in Cap Bon the dam was equipped with 4 fuel water pumps. In all semi-arid Mediterranean regions, ovine breeding is an important income for farmers.
Colilnaire observed actual evapotranspiration of hard wheat 2. All small reservoirs at the test sites were equipped with a water level gauge, an evaporation pan, and two stations for automatic data collinaide. Revue des sciences de l’eau 17, no. After an analysis and synthesis of these projects in each country, seven test sites were chosen and a multidisciplinary approach was adopted. There is little to no exploitation of hill reservoirs that are far from the markets.
Economic, social and environmental studies were made using surveys with the farmers. 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 sites.

The main objective of this work was to build a hydrological model suitable for semiarid Mediterranean catchments with hill reservoirs, with two specific objectives: Hill reservoirs contain fifty thousand to one million m3 of runoff water from watersheds whose areas kac from a few hectares to several km2.
They regulate water flow and thus help to maintain populations in place, ensuring for them real possibilities of development.

Their construction has several objectives:. The observations made during different hydrological periods aided in the understanding of the present geochemical evolution collinarie water and confirmed the importance of reservoir hydrology in this evolution. Among other uses of the reservoir water, cattle watering and domestic needs were also important.
During winter, high potential evapotranspiration values are due to collinaide winds. Intensive cultivation of drip-irrigated tomatoes and peppers 10 ha coexists with traditional irrigated gardens. Micro-meteorological studies on rainfed agriculture allowed the estimation of actual evapotranspiration fluxes for hard wheat at both sites. Since the beginning of the project, annual records of all observations made from September to August at these test sites have been published.
They are integrated in a natural way within the landscape and do not create any particular pollution problems. Water samples were collected seasonally during the project.

A computerized bank of hydrological data was set up. The use of water in the hill reservoirs appeared to be limited, but variable from one lake to the other.
Maps of different watersheds were stored using a geographical information system GIS. Switch to classic view.

At the catchment scale, measurements of energy balance showed a very strong water demand throughout the year. Revue des sciences de l’eau17 2— A hill reservoir is a small lake resulting from a small dam. In addition to a training program and co-ordination activities, four projects were carried out:.
At the same time, studies on sheet erosion and gully erosion were carried out in the watersheds. One station was connected to a tipping bucket colliinaire gauge 0. The parameters describing the watersheds were also recorded in a similar data bank.
Solid transport varied from 1.
