Estuaries are highly dynamic systems, subject to continuous morphological change, which results from complex interactions and feedbacks between the hydrodynamic processes, sediment transport processes and the ecology. The prediction of morphological change in estuaries is theref…

In a recent discussion of research priorities for palaeoecology, it was suggested that palaeoecological data can be applied and used to inform nature conservation practice. The present study exemplifies this approach. It was conducted on three degraded blanket mires in Yorkshire…
As the global population urbanises, the benefits derived from contact with nature increasingly depend upon the presence of diverse urban ecological communities. These may be threatened by changes in land-cover and the intensification of land-use. A key question is how to design …
Although the direct health impact of temperature has been studied extensively, the impact of Urban Heat Island (UHI) on mortality has received relatively little attention. This PhD thesis assesses the combined impacts to distinguish the differential responses between urban and r…
Droughts are one of the most widespread and complex natural hazards, and remain poorly understood in the context of the United Kingdom. Although the UK is perceived as a relatively water rich country, droughts are a recurrent feature of its climate, causing widespread and seriou…
Recent research has indicated that variability of antecedent flows is a fundamental control on the entrainment and transport of sediment in river systems. Specifically, the low flows between successive floods appear to have a far greater influence on the stability of a river bed…
Having arguably led the world in the transition to a high carbon economy, much of Wales today is economically and socially deprived. Even so, a devolved Welsh Government has set ambitious targets to reduce carbon emissions in the devolved areas, while creating employment and eco…
Urban green spaces are useful natural assets that support the development of cities in diverse ways. However, statistics show that these spaces are under severe threat with the situation in Africa been critical. This study sought to assess the governance of urban green spaces an…
The recent spate of floods in many parts of Britain has stimulated substantial interest among scientists, policy makers and the public concerning contemporary trends in flood frequency and magnitude, in particular questioning whether these events exceed historical extremes. Howe…
Tourism has become the most important source for stimulating the economies of countries of the world. It stimulates enormous investment in infrastructure and helps states to improve their balance of payments, which should help to create job opportunities and improve the living c…
Volunteers have been collecting ecological data for centuries. However, volunteercollected data are frequently challenged because they lack the precision and rigour of scientific studies. This thesis evaluates the advantages of volunteer‐collected data and the importance of such…
Humans have interacted with their surroundings for over one million years, and researchers have only recently been able to assess the geomorphic impacts indigenous peoples had on their landscapes prior to the onset of European colonialism. The history of human occupation of Aust…
The Mijikenda sacred natural sites (SNS) contribute towards Kenya’s East African Coastal Forest ecosystem. This ecosystem is highly biodiverse and important to the conservation of many rare and endemic species. The SNS are therefore thought to be very important to biodiversity l…
The aim of the study is to investigate the variability in riverbed permeability fields in an unprecedented spatial resolution and quantify the impacts on controlling hyporheic exchange fluxes. Geophysical surveys were conducted deploying GPR on the floodplain and within the chan…
Paired kitchen-living room dust samples from 30 UK houses were collected for the analysis of BFRs, including PBDEs, HBCDDs and PBEB, EH-TBB, BTBPE, BEH-TEBP, DBDPE. Ninety-six plastic kitchen utensils were collected, screened for Br concentration by X-ray fluorescence spectromet…
This thesis aims to understand the mechanisms involved in pollen transport and deposition in cave environments and the influence of different factors on the composition of the pollen assemblage, with special reference to the problem of the Neanderthal ‘Flower burial’ at Shanidar…
Water supplies have been meeting strict experiments all over the world and the tendencies of reducing precipitations and rising temperatures in the arid and semi-arid of the Middle-East region (such as Iran) aggravate this condition during the last few decades. A proper water pl…
In Egypt, as in most developing countries, highly technical plans are drawn up, but nobody puts them into practice. They always end up gathering dust on the shelves of national agencies or local government without being utilised to make improvements to local economic or environm…
Aeolianites and palaeosols on the Meditcrranean coastal plains of Israel were investigated with luminescence dating in order to explore the sedimentological evidence for climate change in the area and the response to it. The dated samples were taken from sites between the towns …
