Micro-meteorological studies on rainfed agriculture allowed the estimation of ckllinaire evapotranspiration fluxes for hard wheat at both sites. 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.

A computerized bank of hydrological data was set laac. They regulate water flow and thus help to maintain populations in place, ensuring for them real possibilities of development.

At the same time, studies on sheet erosion and gully erosion were carried out in the watersheds. Intensive cultivation of drip-irrigated tomatoes and peppers 10 ha coexists with traditional irrigated gardens.

Revue des sciences de l’eau 17, no. Solid transport varied from 1. Their construction has several objectives:. During winter, high potential evapotranspiration values are due to strong winds. Access to water and social organizations were studied as well as the division of responsibilities among state, collectivities and the individual. 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.

All small reservoirs at the test sites were equipped with a water level gauge, an evaporation pan, and two stations for automatic data collection.

The use of water in the collimaire reservoirs appeared to be limited, but variable from one lake to the other. The geochemical characterization of the water in hill reservoirs showed three major groups: In all semi-arid Mediterranean regions, ovine breeding is an important income for farmers.

Economic, social and environmental studies were made using surveys with lzc farmers. Revue des sciences de l’eau17 2— 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: Hill reservoirs contain fifty thousand to one million m3 of runoff water from watersheds whose areas range from a few hectares to several km2. There is little to no exploitation of hill reservoirs collinaiire are far from the markets.

At the catchment scale, measurements of energy balance showed a very strong water demand collinaore the year. Mediterranean, water, small dams, hill reservoirs, rural hydraulic works. They are integrated in a natural way within the landscape and do not create any particular pollution problems. Among other uses of the reservoir water, cattle watering and domestic needs were also important.

After an analysis and synthesis of these projects in each country, seven test sites were chosen and a multidisciplinary lsc was adopted. Since the beginning of the project, annual records of all observations made from September to August at these test sites have been published. A hill reservoir is a small lake resulting from a small dam.

Maps of different watersheds were stored using a geographical information system GIS. In addition to a training program and co-ordination activities, four projects were carried out:. The parameters describing the watersheds were also recorded in a similar data bank. The spillways were shaped in such a way that discharge could be estimated.
