Article
The ad hoc management of natural environmental features and inappropriate social interventions could cause vulnerability of thriving urban ecosystems. For instance sub-aerial exposure, water-related hazards, urban intrinsic sensitivity, urban adaptation ability or flexibility and urban transformability factors could contribute a potential danger. I...
Article
The Mediterranean coastal city of Annaba (Eastern Algeria) faces a strong urban growth for several decades. Limited east by the shoreline and west by the Edough Massif, the only development opportunity for the city and its harbor is the south part of the plain. Nowadays, alluvial plains are increasingly invaded by urban sprawl with negative impacts...

Article
Algiers has faced flashing urban growth during last three decades. The settlements associated with al-Harrash River became a center of discussion since water scarcity, surface and groundwater contamination and flooding threatened its habitat. The expansion of settlements are causing heavy toll on public hygiene and sanitation, which virtually leads...

The purpose of this paper is to present an investigation on the relevance of the historical water legislation which would adapt to the modern sustainable water management. It is mainly based on the book by Ernest Feline related to the qanat system in the arid M'Zab valley in southern Algeria. It also refers to some related lectures on the tradition...

La souscription de l'Algérie à la Convention mondiale du développement durable en 1995 l'a amenée à initier la révision du Code de l’eau puis des outils stratégiques d’aménagement du territoire. Dès 1996, l’Ordonnance n° 96-13 du 15/06/1996 complétait et modifiait la loi n° 83-17 du 16/07/1983 sur l’eau dans le sens d’une politique nationale orient...

Article
Full-text available
L’analyse des risques hydro climatiques a recours à un outillage théorique et empirique dont les éléments hétérogènes semblent a priori difficilement agrégeables. Si la géographie du cycle de l’eau permet de cartographier leur échelle d’occurrence et donc de gestion, leur évaluation s’établit localement par croisement d’indicateurs du couple vulnér...
Article
La plaine Orientale d’Alger abrite une zone marécageuse traversée d’Ouest en Est par l’oued el Harrach, l’oued el Hamiz et leurs affluents. Pendant longtemps, elle a été l’hinterland de la Capitale pourvoyeur en denrée alimentaire et en eau. Ce n’est qu’à partir du XIXe siècle que son urbanisation démarre avec la création par le Gouvernement França...
Conference Paper
Current state of Algerian cities indicates that numbers of them are exposed to hydroclimatic risks. The flood and scarcity impacts on safety, health, hygiene and ecological balances, should have a heavy outcomes on the urban ecosystem components, especially under the arid to semi-arid climate of our country. To face hydroclimatic risks the strategy...
Conference Paper
During last three decades, in the time natural hazards due to climatic events have been increasing, Algiers has faced a flashing urban growth associated with informal settlements proliferation. Inside its western plain, the coastal wetland crossed by al-Harrash River became more and more threatened by some water related risks such as scarcity, surf...
Conference Paper
En Algérie, les statistiques des maladies à transmission hydrique (MTH) révèlent une réduction globale de leur incidence durant la dernière décennie. Cependant, la persistance de foyers endémiques entretient le risque épidémiologique dans de nombreuses wilayas du Nord notamment, non seulement à l’intérieur de l’arc de précarité qui entoure les gra...
Conference Paper
L’étude des risques hydro climatiques en milieu urbain a recours à un outillage théorique et méthodologique dont les éléments hétérogènes semblent a priori difficilement agrégeables. Si la géographie du cycle de l’eau permet de cartographier leur échelle d’occurrence et d’impact, leur évaluation s’établit plutôt par analyse multicritère (AMC) d’ind...
Conference Paper
La Plaine Orientale d’Alger, située au sud de la Capitale, est une zone marécageuse traversée d’Ouest en Est par Oued El Harrach, Oued El Hamiz et leurs affluents. Pendant longtemps, elle a été l’hinterland pourvoyeur en denrée alimentaire et en eau dont son sous sol regorge. Ce n’est qu’à partir du XIXè siècle que son urbanisation démarre avec la...
Conference Paper
Full-text available
Selon le plan national de changement climatique, à horizon 2020 l’Algérie connaîtra des sécheresses et des inondations récursives alors que les besoins en eau doubleront de volume sous la pression de la croissance démographique et de l’urbanisation continue. Les risques liés à l’eau se déclineront alors en terme de disponibilité, d’hygiène et d’ass...
Conference Paper
En supposant avec un degré élevé de fiabilité que le processus d’urbanisation se poursuivra durant les décennies à venir en Algérie, c’est à des risques fortement anthropisés que devront faire face la ville et ses usagers à terme. La demande sociale de santé publique, de sécurité et de confort est aujourd’hui telle que l’expérience cumulée de la tr...
Conference Paper

Le concept contemporain de gestion intégrée du cycle de l’eau suppose la prise en compte simultanée de toutes les composantes du système hydrologique dans le but de préserver la ressource - quantitativement et qualitativement - et maîtriser les risques qui lui sont liés. Or, les prémisses de cette approche scientifique moderne se retrouvent dans ce...
Conference Paper
If the traditional socio-economic development policies consisted in satisfying the continual increase in the water requirements whatever the cost may be, the sustainable strategy now requires the introduction of two concepts that could seem at the very least revolutionists: - First establishes the necessity of limiting the urbanisation requiring a...
Conference Paper
Under the combined effect of the climate and the urban growth, the natural hydro climatic events (floods, dryness) could reach an exceptional intensity, extent and period. The immediate or progressive impact of such natural cyclic phenomena in term of lack of water can be full of consequences on the urban ecosystem. Consequently, in reference to th...
Conference Paper
The history of the ancient cities reminds some interesting informations about the water policy followed by the past. More especially those one situated in the Maghrib zone, where the physical and climatic items designate a quite different rainfall levels from North to South and from West to East. It means that in such a geographical context any urb...
Conference Paper
The Algiers agglomeration is nowadays faced with two principal kinds of risk tied up with water resources: those liable to some natural and then not controlled factors as flooding, dryness and ground’s instability in one hand; and others due to some human and may be controlled factors as pollution, over exploitation and spoiling in the other hand....
Conference Paper
The Algiers agglomeration is nowadays faced with two principal levels of care tied up with water resources: demand’s satisfaction in one hand and risk’s management in the other. In fact, the present urban growth of the Capital lets presage a quite generalization even an aggravation of the water crisis compromising by term the balance of the local...
Conference Paper
De toute évidence une stratégie de l’eau est fondamentalement nécessaire et conditionnelle à toute urbanisation. De surcroît dans un pays tel que le Maghreb dont les paramètres de l’environnement naturel, qui déterminent un milieu moyennement arrosé à franchement aride, commandent la répartition de la population sédentarisée et donc le développemen...
