Περίληψη | Flooding is one of the most common disasters worldwide. This paper
strives to highlight the hydrological effects of multi-temporal land use
changes in flood hazard. The study area is Potamia basin established in
the broader Yialias catchment basin located in Nicosia -Cyprus. The
certain area has suffered from several flood disasters in the recent
past. Initially, the land cover regime of the study area (last 20 years)
was thoroughly studied using multi-temporal satellite (ASTER) and
implementing g sophisticated classification methodologies such as Object
oriented analysis. Land use/ Land cover (LULC) maps for the periods of
1990, 2000 and 2010 were developed. All these maps were incorporated in
the CA-Markov chain analysis model and the LULC map of 2020 was
constructed. The Markov chain analysis describes the probability of land
cover change from one period to another by developing a transition
probability matrix between two different time periods. Following, the
hydrological analysis was performed using the Hydrological Modeling
System (HEC-HMS). HEC-HMS is designed to simulate the
precipitation-runoff processes of dendritic watershed systems. The
HEC-HMS model was set up in distributed mode, enabling the utilization
of the spatial information on the land use via the Curve number
coefficient. Thus, the 2020LULC map was incorporated in the hydrological
model in order to predict the hydrological behavior of the catchment
area for the next decade. The results were compared with the present
hydrological regime and denoted the future increase of runoff due o the
predicted extensive urban sprawl phenomenon. | en |
