Abstract In the upper Tiber River basin there
is a complex network of artificial and natural reservoirs that can be
considered a laboratory in which reservoir tools and policies can be easily tested.
In this context, a model at the basin scale has been developed for surface
water resource management. This model has many features that allow the user to
easily sketch the river network, to set up the management policies for each
water use, and to retrieve the output. The model is based on three fundamental
algorithms: the first models the river network in terms of the various uses within the
river basin; the second calculates a water
budget, understood as the difference between the total demand and the
available water amount; and the third calculates the water resources in the
basin. This last algorithm can also take into consideration the many political
and administrative constraints that may limit the management criteria.
