Abstract:
A Disaggregation model was tested for arid land stream flow generating. The test was performed on data from Black River, near Fort Apache, Arizona. The model was tested in terms of preserving the relevant historical statistics on both monthly and daily levels, the monthly time series were disaggregated to a random observation of their daily components and the daily components were then reaggregated to yield monthly values. A computer model (DSGN) was developed to perform the model implementation. The model was written and executed on the Macintosh plus personal computer Data from two months we

Abstract:
This thesis examines the potential role of transfer function models in the real-time forecasting of the rainfall-runoff and flow routing processes. The theory of the transfer function model structure and the recursive least-squares estimator is described. The use of a sampling rule to reduce the order of large transfer function models is discussed. Traditional sampling theories and control engineering sampling rules are examined. An hydrological sampling rule is developed and tested, with the conclusion that accurate and parsimonious transfer function models can be calibrated for most of the h

Abstract:
This thesis reports the use of a time-series analysis approach to study the catchment hydrological system of the River Ribble. Rain gauge records, radar rainfall estimates and flow data are used in the analysis. The preliminary study consists of the flow forecasting at Reedyford, Pendle Water (82 km2). Flow forecasts generated from the rain gauge records are better than the radar rainfall estimates over this small catchment. However, the catchment response to rainfall is quick and no clear advantages in extending the lead-time of the forecast can be introduced by using an artificial time delay

Classical time series analysis has well known methods for the study of seasonality. A more recent method of functional data analysis has proposed phase-plane plots for the representation of each year of a time series. However, the study of seasonality within functional data analysis has not been explored extensively. Time series analysis is first introduced, followed by phase-plane plot analysis, and then compared by looking at the insight that both methods offer particularly with respect to the seasonal behavior of a variable. Also, the possible combination of both approaches is explored, spe

Time-series power flow simulations are consecutive power flow calculations on each time step of a set of load and generation profiles that represent the time horizon under which a network needs to be analyzed.

In the specific case of cost-benefit analyses the execution time of time-series power flow simulations can easily become excessive, as typical time horizons

Abstract:
Chaque année, lors de la période hivernale, les hôpitaux sont profondément impactés par l'arrivée des virus hivernaux. Ces virus hivernaux, la grippe et le VRS sont difficiles à anticiper. En effet, ces phénomènes épidémiques ne sont pas parfaitement périodiques et ont un impact principalement sur le temps de séjour des patients plutôt que sur le nombre d'arrivée. Il n'est donc pas possible d'anticiper ces épidémies en analysant directement le nombre de patients arrivant au service des urgences par jour. A posteriori, pour avoir une image de l'épidémie, des tests PCR sont réalisés sur les pati

Dans le contexte de la ville intelligente, le besoin d’informer, d’anticiper, et d’agir sur l’état du réseau routier est à l'origine du développement de nombreuses méthodes de prévision de trafic. L’augmentation de nos capacités à stocker et à traiter des données, notamment en temps réel, ainsi que le nombre croissant de segments de routes équipés de capteurs sont de nouveaux éléments à considérer lors du choix d’une méthode de prévision. Malgré de nombreux travaux de recherche, nous ne disposons toujours pas d’une compréhension claire des critères permettant de prédire efficacement à l’échell

Lieu de développement économique et démographique intense, les zones littorales font l'objet de pressions importantes sur l'environnement et, en particulier, sur les ressources en eau. Bien que la gestion des eaux souterraines côtières bénéficie de nombreux résultats issus de la recherche scientifique, une des problématiques majeures reste la connaissance de la géométrie des aquifères. Des interprétations géologiques de la genèse du bassin Plio-Quaternaire du Roussillon, issues de la stratigraphie séquentielle, sont confrontées, par l'intermédiaire d'une base données, à l'hydrogéologie de cet

The economic growth and the increase in population has led to an increased demand for water for various purposes such as domestic consumption, irrigation, industrial use, power generation, navigation, recreation, and ecological requirements. With the increase in population, the per-capita water availability is continuously decreasing. Due to increase in demand and accompanying scarcity of water the conflict among the potential users of the resource is on raise.
