This study investigates a Devensian glacial conundrum, the provenance of the Norber erratics in North Yorkshire, and the origins of a post-Devensian-deglaciation landform, pedestal rocks with Carboniferous limestone pedestals in England, Ireland and Wales. Investigations to dete…

Eutrophication results in the loss of conservation and amenity value from shallow lakes. Efforts have been made to restore shallow lakes by reducing the external nutrient loading. Removing nutrient-rich inflows can reduce nutrient loading but may alter lake hydrology. This thesi…
This study of slope instability in the Matlock region of Derbyshire uses, and tests the applicability of, a variety of techniques from reconnaissance through to site investigation. The aims have been to (i) provide a greater understanding of landsliding in this area and (ii) pro…
There is growing concern that the adoption of intensive agricultural land management practices in upland areas of the UK over the past 50-60 years may have affected hydrological responses and sediment transfer regimes in river catchments and could, therefore, be contributing to …
Characterisation of the complex geomorphological and ecological structure of river channels into workable units of instream habitat is a key step in enabling the assessment of habitat for river management purposes. The research presented in this thesis uses a range of methodolog…
This thesis uses data sets at a range of spatial and temporal scales to examine the geomorphological response of the Lower Mississippi River to engineering and management. During the twentieth century the geomorphology of the Lower Mississippi River has been transformed by a ser…
Urban areas have well documented effects on climate, such as the urban heat island effect, reduction of wind speeds, enhanced turbulence and boundary layer heights, and changes in cloud cover and precipitation. This PhD examines the impact of the urban surface on the major agglo…
An understanding of the longstream distribution of hydraulic processes is important for evaluating the mechanisms which control the catchment-scale variation of channel stability, sediment transport and siltation, flood generation and aquatic habitats. However, little attention …
Studies of landscape development via primary successional processes are an important area of research for understanding how landscapes evolve into stable, diverse ecosystems. This research sought to assess how geomorphic and hydraulic complexity alter as streams develop followin…
This study investigates the current impact of acid deposition on the structure and function of benthic communities in streams of contrasting pH in mid-Wales, UK, and examines barriers to biological recovery across the sites. The results of field surveys across 30 streams reveale…
This thesis firstly reviews the current literature available on antidune bedforms and their hydrodynamic environment, alongside recent studies of the turbulence environments associated with bedforms in unidirectional flow. Based on this understanding, three suites of experiments…
River bank erosion models are a fundamental requirement for understanding the migration and evolution of river meanders, estimating the potential for land-loss and threat to floodplain infrastructure, and predicting the delivery of contaminated floodplain sediments to aquatic ec…
Housing is one of the key issues that normally forefront the scene when considering challenges of urbanisation and urban growth. It is a fundamental aspect of human life and a major factor in delivering healthy and attractive communities as it serves to define the life space of …
The East Black Sea (EBS) and the Çoruh River basins (ÇRB) of northeast Turkey have a number of challenging water related issues of socio-economic and ecological importance. This PhD thesis aims to understand hydroclimatological variability across Turkey taking a large-scale pers…
The full extent of a landscape’s resilience to the environmental impact of siting wind-based renewables on peats is currently unknown. This research explores if windfarm construction activities have caused disturbance by investigating; time series of fluvial carbon (C) and nutri…
