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. Intensive cultivation of collinairre tomatoes and peppers 10 ha coexists with traditional irrigated gardens.
All small reservoirs at the test sites were equipped with a water level gauge, an evaporation pan, and two stations for automatic data collection. Water samples were collected seasonally during the project. The main objective of this work was to build a hydrological model suitable for semiarid Mediterranean catchments with hill reservoirs, with two specific objectives: Access to water and social organizations were studied as well as the division of responsibilities among state, collectivities and the individual.
They regulate water flow and thus help to maintain populations in place, ensuring for them real possibilities of development.
Revue des sciences de l’eau17 2— There is little to no exploitation of hill reservoirs that are far from the markets. Their construction has several objectives:. In all semi-arid Mediterranean regions, ovine breeding is an important income for farmers. The geochemical characterization of the water in hill reservoirs showed three major groups: The observed actual evapotranspiration of hard wheat 2.
After an analysis and synthesis of these projects in each country, seven test sites were chosen and a multidisciplinary approach was adopted. Hill reservoirs contain fifty thousand to one million m3 of runoff water from watersheds whose areas range from a few hectares to several km2.
On the Kamech site in Cap Bon the dam was equipped with 4 fuel water pumps. A computerized bank of hydrological data was set up.

At the catchment scale, measurements of energy balance showed a very strong water demand throughout laf year. Switch to classic view. Economic, social and environmental studies were made using surveys with the farmers.
Solid transport varied from 1. During winter, high potential evapotranspiration values are due to strong winds.

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. Among other uses of the reservoir alc, cattle watering and domestic needs were also important.
Micro-meteorological studies on rainfed agriculture allowed the estimation of actual evapotranspiration fluxes for hard wheat at both sites. Revue des sciences de l’eau 17, no.

The parameters describing the watersheds were also recorded in a similar dollinaire bank. One station was connected to a tipping bucket rain gauge 0.
The spillways were shaped in such a way that discharge could be estimated. Maps of different watersheds were stored using a geographical information system GIS.

A hill reservoir is a small lake resulting from a small dam. At the same time, studies on sheet erosion and gully erosion were carried out in the watersheds.
The use of water in the hill reservoirs appeared to be limited, but variable from one lake to the other. Since the beginning of the project, annual records of all observations made from September to August at these test sites have been published. In addition to a training program and co-ordination activities, four projects were carried out:.
They are integrated in a natural way within the landscape and do not create any particular pollution problems.
