Journal of Urban and Regional Analysis, vol. XII, 2, 2020, p. 233 - 248 https://doi.org/10.37043/JURA.2020.12.2.7 MITIGATING FLASH FLOODS WITH THE USE OF NEW TECHNOLOGIES: A ΜULTI-CRITERIA DECISION ANALYSIS TO MAP FLOOD SUSCEPTIBILITY FOR ZAKYNTHOS ISLAND, GREECE Stavros STAVROPOULOS1, George N. ZAIMES1, Evangelos FILIPPIDIS1, Daniel C. DIACONU2, Dimitrios EMMANOULOUDIS1 1International Hellenic University, Drama, Greece, 2University of Bucharest, Bucharest, Romania Abstract: Floods can be extremely harmful for the welfare of societies regardless if they are natural or caused by humans. The Mediterranean region has experienced an increase in flash floods frequency and severity. The suddenness and episodic nature of these type of floods makes it more difficult to predict them compared to river floods. In this study, a map was developed in regard to the flood susceptibility of Zakynthos Island with the use a multi-criteria decision analysis. This analysis utilized six factors: a) flow accumulation, b) land use, c) slope, d) rainfall intensity, e) geology and f) elevation. Each factor had a different weight based on their importance in regard to flash floods. The analysis was run in GIS. To validate the developed susceptibility map, the locations of the recorded past floods on the island were utilized. The end product was a validated flood susceptibility map. This map can help the Civil Protection Authority of Zakynthos Island to mitigate communities’ susceptibility to flash floods. Key Words: flood susceptibility map, MCDA, GIS, Mediterranean islands. Introduction When large amounts of water exceed the natural boundaries of water bodies and occupy areas that are typically dry, floods occur. -

Hydraulic Communication Structures in the Vega Alta Del Segura and Its Contribution to Tourism (Modern Age)
Cuadernos de Turismo, nº 42, (2018); pp. 681-683 Universidad de Murcia ISSN: 1139-7861 eISSN: 1989-4635 HYDRAULIC COMMUNICATION STRUCTURES IN THE VEGA ALTA DEL SEGURA AND ITS CONTRIBUTION TO TOURISM (MODERN AGE) Juan Carlos Trigueros Molina Universidad de Murcia [email protected] Curiosity and knowledge encourage society to travel form one side to another. The knowledge about the cultural heritage is a composed core and endogenous tourism. So important is the role played by economic strategies to tourism, as the meaning and informative references relating to the monuments. These revelations cause emotional impressions and moral and cognitive impact on tourists. For this reason, this study is base don the progress of knowledge withn the aim of being a means of improvement when the informative activity exercised by a guide. The present study is based on an interpretation of the past (modern age) and the present on the oldest hydraulic communication structures (bridges, cradles and boats) in the Vega Alta del Segura (municipalities of Cieza, Abarán and Blanca), Murcia (Spain). In the area of research, there are nine bridges currently. After a bibliographical review and to recognize the antecedents of each of them, the historical analysis has been focused on three specific places. These three geographical spaces are occupied by the Bridge of Nine Eyes in Cieza, the Bridge of Iron in Blanca, both of automobile and pedestrian traffic, and the Old Bridge in Abarán of pedestrian traffic. The argument of this work is more inclined towards the tourist culture than towards a cultural tourism. The content shows a progress of knowledge. -

Hydrological Planning Scenarios in the Segura River Basin A
Sustainable Development and Planning IV, Vol. 2 975 Territorial transformation and water utilization: hydrological planning scenarios in the Segura river basin A. Grindlay1, M. Zamorano2, M. I. Rodríguez1, E. Molero1 & M. A. Urrea3 1Urban and Spatial Planning Laboratory, University of Granada, Spain 2Department of Civil Engineering, Section of Environmental Technology, University of Granada, Spain 3Hydrological Planning Board, Segura River Basin Auth., Murcia, Spain Abstract Considering the particular climatic and water conditions of this semiarid region in southeast Spain, the hydrographic basin of the Segura river is a very dynamic territory. This is reflected in the important spatial transformation that it has undergone in the second half of the 20th century, entailing the expansion of irrigated surfaces as well as extension of urban areas, as well as the proliferation of golf courses over the past two decades. The progressive increase in demand owing to such intensive use of water resources is linked to a supply-oriented hydraulic policy, with major infrastructural actions that contribute to a substantial water deficit, as registered by the latest hydrological plan. Meanwhile, the urban supply of water was decisively resolved to make sources of water supply available; recently, thanks to the new desalinization resources and the ensuing guarantee of supply, water is not a limiting factor for urban development along the coast, as reflected in the local urban plan. The current implementation of the European Water Framework Directive stands as a radical change in the orientation of hydraulic policy. Strict environmental supervision, which translates as the maintenance of ecological flows and the restriction of uses, will give rise to planning scenarios within the new hydrological context that maintain a water deficit only with regard to agricultural consumption. -
Assessing the Species in the CARES Preservation Program and the Role of Aquarium Hobbyists in Freshwater Fish Conservation
fishes Article Assessing the Species in the CARES Preservation Program and the Role of Aquarium Hobbyists in Freshwater Fish Conservation Jose W. Valdez 1 and Kapil Mandrekar 2,* 1 Department of Bioscience—Biodiversity and Conservation, Aarhus University, Grenåvej 14, 8410 Rønde, Denmark; [email protected] 2 Department of Environmental and Forest Biology, SUNY College of Environmental Science and Forestry, 1 Forestry Drive, Syracuse, NY 13210, USA * Correspondence: [email protected] Received: 30 June 2019; Accepted: 17 September 2019; Published: 29 September 2019 Abstract: Freshwater fish represent half of all fish species and are the most threatened vertebrate group. Given their considerable passion and knowledge, aquarium hobbyists can play a vital role in their conservation. CARES is made up of many organizations, whose purpose is to encourage aquarium hobbyists to devote tank space to the most endangered and overlooked freshwater fish to ensure their survival. We found the CARES priority list contains nearly six hundred species from twenty families and two dozen extinct-in-the-wild species. The major families were typically those with the largest hobbyist affiliations such as killifish, livebearers, and cichlids, the latter containing half of CARES species. CARES included every IUCN threatened species of Pseudomugilidae and Valenciidae, but only one percent of threatened Characidae, Cobitidae, and Gobiidae species. No Loricariidae in CARES were in the IUCN red list as they have not been scientifically described. Tanzania and Mexico contained the largest amount of species, with the latter containing the most endemics. Many species were classified differently than the IUCN, including a third of extinct-in-the-wild species classified as least concern by the IUCN. -
Challenges and Proposals for Socio-Ecological Sustainability of the Tagus–Segura Aqueduct (Spain) Under Climate Change
sustainability Article Challenges and Proposals for Socio-Ecological Sustainability of the Tagus–Segura Aqueduct (Spain) under Climate Change Álvaro-Francisco Morote 1,* ID , Jorge Olcina 2 and Antonio-Manuel Rico 1 1 Interuniversity Institute of Geography, University of Alicante, 03080 Sant Vicent del Raspeig, Spain; [email protected] 2 Department of Physical Geography and Regional Geographical Analysis, University of Alicante, 03080 Sant Vicent del Raspeig, Spain; [email protected] * Correspondence: [email protected]; Tel.: +34-965-903-400-(1097) Received: 20 July 2017; Accepted: 5 November 2017; Published: 9 November 2017 Abstract: Since its inauguration in 1979, the Tagus–Segura Aqueduct has become one of the hydraulic infrastructures that has had the most significant socio-economic repercussions in Spain during the past few decades. The aqueduct is significant for its strategic importance and developmental potential for south-east Spain, where it provides water for agriculture as well as for tourism and urban consumption. The aim of this study is to analyze the uncertainties regarding the future functioning of this infrastructure in view of the reduction of water resources and a higher frequency of drought episodes due to climate change. To this end, an analysis was performed on previous studies of hydrological plans, regulations and studies on climate change in order to enable an assessment to be made of the possible effects of these changes on the normal functions of the Tagus–Segura Aqueduct. Consideration is also given to the new management rules that have regulated this infrastructure since 2014, the use of alternative water resources, and proposals such as measures to increase resilience in light of future climate change scenarios and their effects on the Mediterranean. -

Although in general it has had a positive impact, research has also revealed spatial and social disparities in the distribution of funds. Our primary source was the files for all the LEADER projects processed in Andalusia between 2007 and 2015. In addition to successfully executed projects, we also focused on “unfunded” projects, those in which, although promoters had initiated the application procedure, a grant was never ultimately obtained. Project failure must be studied so as to avoid biased findings. We then classified these projects within the different types of rural area and analysed the behaviour of the different promoters in these areas. Relevant findings include: project success or failure varies according to the different types of rural area, as does the behaviour of the different promoters; the degree of rurality can hinder project success; young and female entrepreneurs were more likely to fail; the type of promoter is strongly influenced by the distance to cities in that companies and Individual Entrepreneurs tend to invest in periurban spaces, while public sector promoters such as Local Councils are more prominent in remote rural areas. -

According to the information provided by European Member States in the framework of the European Directive 92/43/EEC (Habitat Directive), the main threat to these ecosystems is represented by morphological and hydrological changes. The present work focuses on six lagoon fish species included in the Habitat Directive annex II (species requiring conservation measures: Aphanius fasciatus, A. iberus, Knipowitschia panizzae, Ninnigobius canestrinii, Valencia hispanica and V. letourneuxi) that spend their entire life cycle in the Mediterranean priority habitat 1150* “Coastal lagoons”. The overview of the current scientific literature allowed us to highlight how the presence and abundance of these species may provide important indications on the conservation status of coastal lagoon habitats. In fact, their occurrence, distribution and biology depend on the presence of peculiar structures, such as salt marshes, small channels, isolated pools and oligohaline areas. Coastal lagoon fragmentation and habitat loss have led to a significant reduction in genetic diversity or local population extinction. -
Effects of Enhanced Hydrological Connectivity on Mediterranean Salt Marsh fish Assemblages with Emphasis on the Endangered Spanish Toothcarp (Aphanius Iberus)
Effects of enhanced hydrological connectivity on Mediterranean salt marsh fish assemblages with emphasis on the endangered Spanish toothcarp (Aphanius iberus) Patricia Prado, Carles Alcaraz, Lluis Jornet, Nuno Caiola and Carles Iba´n˜ez Aquatic Ecosystems, Institut de Recerca i Tecnologia Agroalimenta`ries, Sant Carles de la Ra`pita, Tarragona, Spain ABSTRACT The hydrological connectivity between the salt marsh and the sea was partially restored in a Mediterranean wetland containing isolated ponds resulting from former salt extraction and aquaculture activities. A preliminary assessment provided evidence that ponds farther from the sea hosted very large numbers of the endangered Spanish toothcarp, Aphanius iberus, suggesting that individuals had been trapped and consequently reach unnaturally high densities. In order to achieve both habitat rehabilitation and toothcarp conservation, efforts were made to create a gradient of hydrologically connected areas, including isolated fish reservoirs, semi-isolated, and connected salt marsh-sea areas that could allow migratory movements of fish and provide some protection for A. iberus. The fish community was monitored prior to, and for three years after rehabilitation. Results showed an increase in the number of fish species within semi-isolated areas (Zone A), whereas areas adjacent to the sea (Zone B) increased the number of marine species and decreased that of estuarine species (ES). Yet overall differences in fish assemblages Submitted 9 October 2016 were much higher between zones than among study years. Generalized linear models Accepted 21 January 2017 (GLMs) evidenced that distance to the sea was the most important variable Published 28 February 2017 explaining the local diversity of the fish community after restoration, with Corresponding author occasional influence of other factors such as temperature, and depth. -
Hydrometeorological and Hydraulic Factors and Problems Related to Floods in Arid Regions of Spain
U.S.- Italy Research Workshop on the Hydrometeorology, Impacts, and Management of Extreme Floods Perugia (Italy), November 1995 HYDROMETEOROLOGICAL AND HYDRAULIC FACTORS AND PROBLEMS RELATED TO FLOODS IN ARID REGIONS OF SPAIN Juan B. Marco Universidad Politecnica de Valencia Departamento de Ingenieria Hidraulica y Medio Ambiente 46071 Valencia SPAIN Abstract. Meteorological and hydrological aspects and hydraulic problems related to extreme floods, which occur in arid regions of Spain, are reviewed. Small coastal basins with steep slopes and little vegetation cover are characteristics of these regions in which "flash floods" develop. They are produced by large convective rainfall, resulting in very intense soil erosion and deposition. The flow in alluvial cones is basically two-dimensional, unsteady, and often supercritical. Using mathematical models that incorporate these features are typically prohibited because of the cost associated with topographical precision requirements. Since a large number of dams has been constructed and are operational in Spain, management of reservoirs considering the potential of flood events has become an important problem. 1. GEOGRAPHIC INTRODUCTION Spain is a large (505,000 km2) and high country with an average altitude of 540 m.a.s.l., crossed by important orographic systems running East to West. The Iberian system and some of the eastern mountains complete the division of the Peninsula into two unequal portions. Basically, the Iberian Peninsula can be thought of as a large plateau, encircled by mountains on three sides and gently tilting toward Portugal. Due to this orography, most large Iberian watersheds (the Rivers Duero, Tagus, Guadiana and Guadalquivir) flow to the Atlantic Ocean, while the River Ebro (86,000 km2) forms the only large Mediterranean basin.
