| description | <p>Small reservoirs are widely used for storing water, especially for
irrigation purposes. During the last decades, in Italy many of these
reservoirs have been dismissed, becoming an untapped resource. As a matter
of fact, maintenance problems connected to these structures together with
their natural tendency to silt have favored the use of other water supply
resources such as withdrawal from wells.</p>
<p>The increase of drought periods and the high water volume demand for
agricultural purposes suggest to evaluate a full and rational use of all
water resources, leading to a rediscovery and enhancement of untapped
resources. Specifically, this research focuses on small reservoirs and on
their potential contribution to a sustainable water management in
agriculture. Unfortunately, there are no reliable data on their number,
spatial distribution and potential storage volume. The aim of this work is
to define reservoir spatial distribution and evaluate potential available
water volumes. The upper Tiber river basin has been selected as a case study
for the methodology proposed. The work starts from the acquisition and
re-elaboration of the old census of small reservoirs, evaluating, through
GIS and regression techniques, the distribution over the territory and the
available volumes. Then the reservoir census and the derived database were updated for the period from 2015 up to 2019 introducing combined
computational procedures of remote sensing techniques and GIS, based on
satellite images and water index calculation. The results of the semi
automatic procedure used show good performance in lake identification,
making it a promising tool for a fast and reliable water body identification
and evaluation in wide areas.</p> |
