Full textEssaouira beach borders a famous and densely populated bay characterised by a complex and fragile environment that is presently, however, in a state of geomorphic equilibrium. The processes prevailing in the bay, under the triple command of winds, waves, and to a lesser extent, tides, vary considerably in time and space, and could be durably modified in the future under growing human pressures and unreasonable planning. In order to understand the sedimentary morphodynamics of this beach and of the nearshore zone, several field experiments, involving topographic, hydrodynamic and grain-size monitoring, were carried out from 2004 to 2006. The experiments were aimed at highlighting seasonal, intra-annual and monthly patterns of evolution of the beach, especially under the influence of a nearby wadi, the Ksob, which is the main sediment purveyor of the beach. An additional objective of the study was also to monitor variations in the beach sedimentbudget following a major wadi flooding event. The hydrodynamics measurements involved wave and current parameters and were analysed in the light of the marked changes in wind intensity affecting the area. The currents flow dominantly alongshore to the south and southwest north and south of the bay, and exhibit bi-directional flow along the bay beach under both calm and high-energy conditions. The latter bay currents are more pronounced during high-energy conditions. The topographic data highlight longshore and cross-shore variations in beach morphology and their spatio-temporal changes. Essaouira bay comprise a complex beach sediment cell composed of several micro-cells. The Ksob plays an important role in the dynamics of these cells. The dominant winds from the north transport significant quantities of sand to the south in the form of barkhanes that are trapped in the esturary of the Ksob. During river flood events, these sands, as well as fresh inputs brought in by the wadi, are injected in the nearshore zone of Essaouira bay, and are subsequently redistributed onshore, and along the beach by tidal currents ans currents generated by refracted swell. A planned resort construction in the Ksob estuary as well as the projected new Zerrar dam 30 km upstream of the bay could result in serious disequilibrium of the fragile sedimentary system of the bay

Full textThe objective of this research in hydroclimatology is to define the general flow characteristics conditions of the oued Grou, as a knowledge of water resources, in a region which is marked by a grave dryness. Tributary river of Bou-Regreg, the grou is representative of the characters of the border of south and south-est of the plateau central. The channel seems enough regular although it crosses hilly regions with watertight substratum, characterised by a great discontinuity of vegetal cover. The type of climate is semi-barren mediterranean. The essential characters are represented on one hand by variability which is linked to a great year irregularity and at the existence of sequences of dry and wet years, and, on the other hand, by a great contrast of seasons (alternance of a wet, clement season and a warm, dry season). The river flow follows the distribution of precipitations with two distinct seasons, a short high flow and a long period of low flow. The study of average shows, in terms of frequencies, how intervenes the prevalent list of weather conditions and lithology in the flows. This list is confirmed with a statistical study of extreme flows (rising and lowest water levels). The knowledge flows is realised at the catchments areas controlled by hydrometric stations in the water balances. The water balance use the models of space quantification of rain, temperature and the determination of characteristics flows by analysing hydrological phases. This approach shows the dominating effects of permeable formations and scarceness of water tables, favours the overland flow and bounds the alimentation during low flow. This research shows the necessity to increase the knowledge of water resources and how the present indufficient system of measure must be improved

Full textThe Aptian-Early Albian interval of the southern Tethyan margin is poorly understood since sedimentary successions are frequently incomplete and dating is difficult. The Essaouira-Agadir Basin (EAB), Morocco, presents numerous, very good and accessible outcrops of the Early Cretaceous series. The aim of this work is to (1) establish an integrated stratigraphic framework of the Aptian-Albian series based on (a) high-resolution ammonites and calcareous nannofossil biostratigraphy, (b) identification of sedimentary discontinuities and (c) carbon isotope stratigraphy; (2) reconstruct the paleoenvironmental evolution during this interval through both sedimentary facies evolution and qualitative and quantitative nannofossil analyses, and (3) propose a functioning model for the sedimentation on the mixed, carbonate/clastic ramp of the EAB.In the EAB, the Late Barremian is defined by the sarasini ammonite zone and the NC5 nannofossil zone. The Barremian/Aptian boundary is defined by ammonites. The Early Aptian is defined by the deshayesi to furcata ammonite zones, and is bounded by a first minimum 13C value at the base and a first maximum value at the Early/Late Aptian Boundary. The Late Aptian interval, is defined by four ammonite zones (martini, melchioris, nolani and jacobi), two discontinuity surfaces, four maximum and minimum 13C values, and by the upper part of the NC6, the NC7 and the lowermost part of the NC8 nannofossil zones. The Aptian/Albian boundary is placed within the discontinuity D4 (base of the Leymeriella tardefurcata ammonite zone), supported by the First Occurrence (FO) of the Prediscosphaera columnata and Hayesites albiensis nannofossil taxa, and by decreasing 13C values. Early Albian times are represented by the tardefurcata and mammillatum ammonite zones, the FO of Hayesites albiensis, and by minimum 13C values.The facies and depositional environments of the Aptian-Early Albian rocks are identified based on their lithology, sedimentary structures, fossil content and microfacies. These allowed to identify (1) four types of key surfaces related subaerial or submarine erosion, (2) four sedimentary carbonated facies in the Aptian corresponding to outer to inner ramp depositional environments, and (3) four Early Albian sedimentary facies, represented by sandstones and shales, of basin to middle ramp depositional setting. These facies reflect deposition in adjacent and gradational paleoenvironments. The Aptian-Early Albian stratigraphic interval of the EAB, has been subdivided into two major cycles, floored by two major erosional surfaces. The latest Barremian-Aptian cycle is underlined by a major karstified-erosional surface and consists of four third-order depositional sequences. The Early Albian cycle, overlies a major submarine erosional surface, and also contains four depositional sequences. In each cycle, the vertical changes in facies indicates a deepening upward trend related to sea level rise.The carbonate production in the EAB is higher in the Aptian than during the Early Albian, due to warm conditions, slow rise of sea level, shallow depth of the basin, and little detrital influx. The nannofossil total absolute abundance decreases from the Aptian to the Early Albian, due to increasing sedimentation rate, associated with rapid subsidence. The nutrient input, fertility and calcareous nannofossil primary productivity is higher in the Early Albian with respect to the Aptian, and are mainly controlled by rising sea level and upwelling currents. The Latest Aptian-Early Albian period is characterized by a high abundance of cold taxa, and the migration of cosmopolitan biota from Boreal realm into the Tethyan realm, which may reflect the occurrence of a glacial climatic event

Full textThe hydro-archeological study of the Tassaout basin, situated in the western atlas region of marocco, has revealed a large number of remains of the ancient irrigation network which ran through the region. This collection of ancient canalizations (seguias), dating from the XII up to the XIX century, have been realized under powerful regimes which had the capability of bringing to fruition long term projects such as those discovered. The existence of these regimes (state, collective, regional or religious) have left their mark on the agrarian landscape of the basin in creating different models of hydraulic earthworks. The human activities which have held sway over the different eras during the evolution of the basin, is traced within the structure of these ancient edifices. Their diversity, marked in the landscape reflects the changes in climat as well as in politic, economic and social context and provides a model of the history of this region

Full textThe basin in question is situated on the north of the central of the high atlas (in morocco). This study demonstrates that the understanding of the hydrology of n'fis flow depends of its geographical space, the organization and the structure of which we have tried to investigate in its three dimensions and in its evolution. We have used the hydrological geographical methode : in the first part we study the hypsometry and the hydrographical network of the basin, we have analysed and then cartographied of the differents hydrological locals(that is particulars soils that are homogeneous and the same hydrology) however,such analysis and comprehension of this flow necessitate the study of its climatic aspect and the partition of its features in time and space. These points are discussed in the second part. Finally the third part deals with hydrometrical data that come from the three stations of "jaugeages"(lalla takerkoust,imi n'elhamam and iguir n'kouris) after analyzing the annual and monthly flow and after scaning the hydrogams of bath dearth and abundance years, we propose a hydrolo gical model to the n'fis basin

Full textThe basin of oued Ouarzazate is situated in the south of the Hight-Atlas chain. This area, for the most part arid and desert, is occupied by diverse origins populations. The latter are concentrated in the bottom of the mountainous valleis and in the oasis. The constraints of the natural environment had greatly influenced the economic and social organization of these populations, imposing in more particularly the agro-pastoralism, the development of irrigation's technics and of suitable farming, and a rigorous management of the social fellowship. Availabilities of arable lands and availabilities of water had thus, designed two original landscapes. Oasis where, arable lands being relatively stretch, the agriculture dominates but is practised on reduced and discontinuous perimeters, in terms of the availabilies of water. In these lands, technics of intensive farming are used, and the mains of water are collectively well-kept. An area of mountains where, the availabilies of water are relatively abundant, the arable lands are so reduced that breeding seems possible. The efforts some generations of pesants, and of a very important fellow ship had led to the creation of long bands of terraces hooked side the mountains, where an autosusistence agriculture is practised. The basin side of oued Ouazazate, like every other Maroccan open countries, is in full mutation. The emigration and opening up of the area on external world had involved changes in the population's behaviour. Now we attend the bursting of the traditional society and decomposition of the agro-pastoral equilibrium

We tried to study the climatical conditions that governs the cycle of water, who are the motor of ras el maa hydrological regime. The precipitation is one of the factors which has a certain influence on ras el maa annual discharge. The second : we took the studies factors in relations with gensisflow. The drainage basin is very simple, it has two homogenous and different unities : 1-the limestone mountain. 2-the lower country with flysch. Every unity has its geological and geomorphological structure, in its relation with the channel network. The third : we studied her, temporal discontinuities to solve a wide range of hydrological problems is that of hydrographonalysis. We analized the hydrological phases for the determination of the hydrological regime on the ras el maa spring. The results give information about hydrological comportement, it depands on the climatical, geomorphological factors in the drainage basin. In the way, the ras el maa spring translats the geographical data together on the ras el maa basin

Full textThe bassin of the lebene wadi is a heterogeneous entity integrating the southern rif's and the pre-rif's unity. Its structure is the result of carrying, resting on the original unities. At the end of the miocene, all of it was put through active tectonics. The lithostructural contrast and the differential erosion explain the organization of the morphological system in which the dense hydrographic network has resulted in the present from of the relief. Hydrographic network has resulted in the present form of the relief. Six levels belonging successively to ancient. Middle and recent quaternary periods trace the basin's evolution. The karstic froms and the slopes which bear marks of the col climate have much developed since. Most of the elements of the relief bear thick detrial formations which constitute at present a stock of mibilizable materials. The deposits that have followed the latest rharbian accumulations reflect the chemical, hydraulic, mechanical and anthropical erosive activity. The hydraulics of the lebene express the brutal character and the exterme variations depending directly on the precipitations and governed by its morphometricla and morphological characteristics. The average hydrological outcome is almost stable. The outflows of exceptionnally dry or humid years show exterme deviations regarding the module. The wintertime floods are brutal and the summertime low water is frequent and durable. Al of this has repercussions on the natural environment and the human society. The hydrochemics of the water show a strong concentration of ions of the sodium-chlorine

Full textUntil recently, water was considered abundant and inexhaustible, and increased mobilization was the answer given to the increased needs related to the increase in human activity. Nevertheless, with the emergence of use conflicts, the technicist ideology has been called into question and has given way to more integrated models of management. IWRM and the establishment of basin organization have therefore become imperatives of good governance of the water sector, widely promoted by "international policy entrepreneurs". Morocco undertook a comprehensive reform of the water sector in 1995, based on these two principles, which led to the creation of a basin agency.Two decades later, the articulation of the legal and institutional framework of the sector seems inefficient. The constraints related to path dependencies and the institutional environment have, in fact, largely shaped the Agencies creating an important gap between the "Basin Agency Model" and its Moroccan translation. The analysis of the Agency's action in the Tensift Basin reveals that its power is being diluted in favor of other sectors that maintain their historic prerogatives over the resource. It is moreover retained at the central level, by the ministry of supervision. Facing the economic and political stakes that operate at the basin level, and which limit its fields of action, the Agency is forced to ‘laisser- aller’ attitude, which is in itself a form of demand management that allows to operate a 'natural selection' carries inequalities and social risks as well as increased environmental degradation

Full textEventhough they supply moulouya's wadi, mountain summits of the mid and high atlas bereaves the wadi of the atlantic moisture. So that the more we move away from the mid and high atlas summits downward the wadi, the more the wadi dries. In effect, the average yearly pluviometry does not exceed, in fact, 200mm in the major parts of the basin and 400mm near the mediterranean plains. From another standpoint, not only was pluviometry irregular all these past years, but it was variable within the same year. Thus, because of the aleatory seasonal rain periodicity, precipitation was abundant only during a short rainy period : not more than four days. And, whenever a year is marked by the rains, it was due, so to speak, to heavy showers. The effects of the long dried periods which, by and large, follow condensed daily and or episodic rains, are not lessened by natural milieu elements. This is why the impermeable surfaces of the region--of moulouya--along with the vegetable areas are continuously deteriorated both by drought and by heavy run-iff ; which drought and heavy run-off hinder water butt reconstructions and lead to fluid and solid land output. Nevertheless, an abundant hydrological spring (from march to june), maintained by spring rain and stocks of snow which remain from the previous winter in the summits, create a number of huge crues to the wadi and to its tributaries. As we have said before, these crues become important downwards the mediterranean because of the high pluviometry and the apparition of the wadi's principal tributaries. If the region of moulouya receives no overflows during a certain period, the etiages, which recur systematically every summer, affect seriously, instead, the wadi. For instance, in the year of 1983-84, and after a long drought, nearly all the sherriffean kingdom wadis knew a serious low water. This was the case particularly with moulouya wadi : from its spring to the inferior basin, the wadi was in a complete drainage which lasted seventy days

These images offer the possibility to identify with precision the different carbonate minerals and to allow diagenetic facies characterization. The approach is to calculate an index of carbonate, the Normalized Difference Carbonate Index (NDCI) to study the deepening of the main absorption band of carbonates and a supervised classification method based on the Spectral Angle Mapper (SAM) to study the overall shape of reflection spectra of carbonates and to map other accessory minerals. This method has allowed the development of mineralogical maps supplemented by their degrees of crystallinity

Full textThis research has aspectific aim : to make its contribution to the hydrologic study of a drainage basin which hasn't got any hydrometric equipment, the river zaz's one(area of ouezzane, morocco). We have succeeded in collecting a vast amount of hydrologic and geomorphologic data by means of geographic, scientific method. Through the observation of the ground which is minutely detailed. And the global understanding of the drainage basin, its complexity and its dynamic characteristic which can be seen through its various geographic components (geological structure, slope system, biogeographic structure, climatic structure and society). Processing these data has enabled us to define the hydrologic system of the drainage basin in space and in time, through sharp analysis, delimitation and cartography, that is : - first the real functional drainage pattern at the time of the total saturation of the drainage basin, its draining off density and its dynamics. - secondly the hydrologic seasons,their date of occurence, their intensity and length frequency, their hydrologic stages and their geomorphologic procedures. - finally the hydrologic soils : homogeneous sections of space which experience the same hydrologic reactions and procedures under an identical climatic sequence. The thorough knowledge of hydrologic soils and hydrogeomorphological dynamics which characterize them have enabled us to respond to the development demands in order to protect the natural environment. To that effect measures of protection and safeguard for each soil have been suggested. Thus allowing us to convert the present agricultural system, which is a social and ecological crisis, into an agricultural system which would permit "fellahs"* to improve their standard of living and allow them to fight in a methodically intelligent way against the destruction of the soils and their hydrologic reserves

Full textThis study introduces the role of commerce and transport in the territorial organisation of the region of chiadma and haha. A territory that covers all the southern atlantic morrocan plains and the hights the atlas piedmont (6330 km2). Yet, its urbain system remains too weak and its economy encounters many difficulties hindering its progress because of the insufficience of the economic infrastructtructures, the archaic and traditional system of agriculture-productions and the absence of modern means of communication which explains the absence of a big flow of motorised means of transport. Administraters consider chiadma and haha as an homogenous administrative region. But for the local population, on the other hand, this entity is composed of two distinct areas. Moreover, when we analyse this area in terms of commecial exchange and means of transport, the borders of both zones impose a kind of radical modification. The point of this study is to demonstrate through analysing commercial zones of influence-meaning cites-,regional "souks", commercial circuits, and travelling means, that, commercially speaking, the region of chiadma and haha is deeply broken up. This is, also, because of the powerfull-growing neighbouring towns and built-up areas. Even essaouira, which is the region's biggest city, is still considered as secondary in the organisation of commercial regional exchanges

Full textThe aim of this hydri-climatological study of the docks of n'fis, rheraya, ourika and zat, is to tackle the various physico-geographical factors of the flow and the hydrometical parametrs of the atlasics dicks. These latters show the main thouroughfares, feed the river of tensift especially on its left bank. This study lead us to face the needs and the ressources of water, and to valorise the hydraulic potential in the tensift area. So we raise the difficulties of the development planning scheme within the atlasics docks to improuve or to solve, in a way the water problems in the area

Full textThanks to an intensive field work undertaken in spring 2000 with the collaboration between various French and Moroccan organisations, numerous Crocodyliformes remains has been recovered from the phosphatic marine layers from the Cretaceous and Paleogene of the Oulad Abdoun Basin, Morocco. Two taxa have been found in these deposits, eusuchians and dyrosaurids, represented by four and eight species respectively. Among eusuchians, the occurence of three gavialoids can be noted. One is a thoracosaur, which are reported for the first time in Africa. A phylogenetic analysis reveals that Thoracosaurus is a monophyletic taxa, and Maroccosuchus zennaroi, a previously described eusuchian from the phosphates of Morocco but completed with new material, is the most primitive tomistomine. Until know, the dyrosaurids formed a poorly known taxa. A taxonomic revision shows that "Hyposaurus" bequaerti should be transferred to Congosaurus, that Hyposaurus wilsoni, H. Nopcsai and Rhabdognathus rarus are nomina dubia, and that two skulls from Rhabdognathus are two new species. Three new dyrosaurids from Morocco are described, and a phylogenetic analysis of Dyrosauridae within the Crocodyliformes setting shows that convergences due to the longirostrine morphology remain problematic in phylogenetic analyses. The diversity observed in the Oulad Abdoun Basin indicates a strong diversification during the Paleocene, whereas the Crocodyliformes were extremely rare during the Maastrichtian. Then, they have apparently not been affected by the K-T crisis, but probably have taken advantage of the other marine reptile disappearance, to colonise the main part of their ecological niches as soon as the Paleocene

Full textThe phenomenon of the drought in Morocco is studied by approaches which try to explain its organization in time and in space. From a regional example, this work engages a reflection on this phenomenon and its characterization. The general context of the "haut Sebou" basin allowed to highlight the natural contrasts which characterize its geography. Infiltrations are generalized upstream in the basin and announce lowness and fragility of resources in water available. The recent climatic drought and its characterization was led from data rainfall. The temporal variability of the climate is evident and it maintains a non disturbing average situation until the 70s. On the other hand, the last 25 years are called "organized", because there is a trend with annual precipitations more and more weak. This rainfall deficit is accompanied with a longer dry season downstream in the basin. The use of methods of cartography of precipitation (simples interpolators, stastical models, multivariate geostatistics) and the contribution of additional variable (DEM and NDVI) allowed to realize maps of annual average precipitation for different periods. The interannual variability of the climate and the spatial variety of lithologic conditions show the incidence of the climatic drought on the hydrological regime of "haut Sebou" and evidence a very complex functioning. Campaigns of measures of the low-water discharge confirm the spatial heterogeneousness of resources in water, inherent to the anisotropy of the crossed aquifers and to the variety of the environment. The man in the "haut Sebou" can, by the interventions, give evidence of a know-how in the use of the available waters, but he can also behave in a irrational way face to face of this resource
