Hydrologic moment of a watershed area

Abstract:
Hydrologic moment of the watershed area is defined as the static moment with respect to
the outlet of the watershed. In this paper we show two different ways to get the
hydrologic moment through GIS tools: by dividing the watershed into sub-watersheds
from the drainage network, or by dividing the watershed into areas related to the distance
to the watershed’s outlet. The Reservoir Geomorphological Instantaneous Unit
Hydrograph is determined for each value of hydrologic moment previously obtained, and
these hydrographs are applied to two watershed events. The results are analysed in order
to show an appropriate and accurate way to determine the hydrologic moment.
Keywords: Hydrologic moment, Gis, sub-watersheds and iso-distances, Unit Hydrograph.

A GIS approach to monitor territorial transformations:

Abstract:
Purpose:
The study intends to develop a digital procedure to ‘automatically’ create cycle paths
compatible with regional requirements.
Method:
To achieve this goal a GIS will be used as a graphic tool to identify and assess the routes.
Result:
The results validate the proposed digital approach, highlighting the substantial
overlapping between the design route and the automatically generated route.
