Abstract:

This research deals with the estimation of rainfalls and floods for locations at which the corresponding data are unavailable (ungauged sites). The overall study can be divided into three different parts. The first part explores the validity of the distributional similarity of the rainfall time series aggregated at different time scales. Based on the theory of multiplicative cascade process, a scale independent mathematical model has been proposed to describe the probability distributions of rainfall time series aggregated at different time scales. It has been demonstrated that the multifracta

Abstract:

Organization culture has been studies by distinct knowledge areas, such as Anthropology Sociology, Psychology and even Administration. The interest on this subject increased in the eighties and a lot of studies have been conducted, in order to understand better what organization culture really is and how it can be analyzed. However, few of those studies have been indeed concerned to understand how is the organization, what it does, how its members behave. Most of them are based on functionalist approach of an integrative and manageable culture, and they analyze only the artifacts. Nevertheless

Kovacs (1980) adopted the Francou and Rodier empirical flood calculation method and applied it to 355 catchments in South Africa. He revised his study in 1988 to also include the southern portions of the Southern Africa subcontinent. No method other than the Francou and Rodier empirical flood approach in the reviewed literature was found to be suitable for the purpose of this

Abstract:

Flash floods are one of the most devastating natural hazards, claiming numerous lives and tremendous economic losses. One of the main reasons for their catastrophic potential is the limited time available for precautionary measures, such as warnings or evacuations. Early warning systems (EWSs) play a key role for emergency managers to react in a timely manner to upcoming floods and effectively mitigate the impacts. This thesis explores possibilities to enhance the methods available for flash flood early warning and thus improve the operational decision support. While a variety of existing me

Abstract:

The development of regional flood-frequency equations is a key component of engineering infrastructure design and flood risk assessment at ungauged sites. These equations are constructed based on regression analysis techniques to study the connection between peak flow observations and different explanatory variables. However, many regions of the world remain poorly gauged or have experienced dramatic changes in land use or climate that make past observations less useful. To remedy this situation, we need to interpret and construct these regional equations based on physical principles of water

Dans une premiere partie deux methodes susceptibles d'apporter rapidement des informations hydrologiques sont explores: une methode experimentale a base de simulations de pluie physique sur diverses petites parcelles d'un bassin versant s'avere difficile a mettre en uvre notamment si le sol est couvert de vegetation. L'autre approche est statistique. En analysant les evenements pluie-debit faibles a moyennement fo

Ce volet inclut des mesures de pression de l'eau dans le sol et de niveaux des nappes (fugitives ou perennes) sous un versant (ligne de plus grande pente perpendiculaire a la riviere), et une analyse approfondie des sols du versant: granulometries, conductivites hydrauliques in situ mesurees a l'aide de differents appareill

L'objectif de ce travail est une conlribution à l'analyse des processus de formation des crues sur un bassin méditerranéen à l'occasion des épisodes pluvieux. Nous avons essayé de comprendre les caractéristiques hydrologiques d'un bassin par une démarche mécaniste. Pour cela, nous avons étudié la part, dans le débit de la rivière pendant les crues, du débit provenant d'un écou!ement soit par ruissellement généralisé, soit souterrain ou de subsurface, soit sur zones saturées contributives. Le bassin versant a été schématisé comme la succession de deux unités hydrologiques: le versant et le rése

Aufgrund ihrer definierten Größe und isolierten Lage eignen sich Inseln als Modellsysteme in der ökologischen und evolutionären Forschung.

Reliable estimates of design flood quantiles are often necessary at sparsely gauged/ungauged target locations in river basins for various applications in water resources engineering. Development of effective methods for use in this task has been a long-standing challenge in hydrology for over five decades.. Hydrologists often consider various regional flood frequency analysis (RFFA) approaches that involve (i) use of regionalization approach to delineate a homogeneous group of watersheds resembling watershed of the target location, and (ii) use of a regional frequency analysis (RFA) approach

Abstract:

Flood is one of the worst natural disasters, which brings disruptions to services and damages to infrastructure, crops and properties and sometimes causes loss of human lives. In Australia, the average annual flood damage is worth over $377 million, and infrastructure requiring design flood estimate is over $1 billion per annum. The 2010-11 devastating flood in Queensland alone caused flood damage over $5 billion. Design flood estimation is required in numerous engineering applications e.g., design of bridge, culvert, weir, spill way, detention basin, flood protection levees, highways, flood

Abstract:

From 1981 to 2010 flooding claimed an average of 92 lives each year in the United States. According to the National Oceanic and Atmospheric Administration National Weather Service, in 2010 the number of flood-related fatalities (103) was second only to heat (138). Flash flooding is especially dangerous as sudden, torrential downpours from thunderstorms can cause gullies, streams, and creeks to rise quickly and become an immediate risk to life and property. Across the southern Appalachian Mountains this threat is aggravated by steep terrain and the rapid accumulation of rainfall in narrow valle

Sixteen species were not native to the flora of Arizona and represent 9.5% of the flora. Nevertheless, the study area does not appear to be significantly damaged or degraded in spite of its historical and current land use.

Abstract:

Design flood estimation in the range of frequent to medium (2 – 100 years) and large to rare (greater than 100 and up to 2000 years) average recurrence intervals (ARI) is frequently required in the design of many engineering works such as design of culverts, bridges, farm dams, spill ways, land use planning and flood insurance studies. These sorts of infrastructure works and investigations are of notable economic significance. Design flood estimation is ideally made adopting a flood frequency analysis technique; however, this needs a relatively longer period of recorded streamflow data. In man

abstract: The Cape Floral Region (CFR) in southwestern South Africa is one of the most diverse in the world, with >9,000 plant species, 70% of which are endemic, in an area of only ~90,000 km2. Many have suggested that the CFR's heterogeneous environment, with respect to landscape gradients, vegetation, rainfall, elevation, and soil fertility, is responsible for the origin and maintenance of this biodiversity. While studies have struggled to link species diversity with these features, no study has attempted to associate patterns of gene flow with environmental data to determine how CFR biodive
