An investigation into the factors affecting the behaviour of Highway Filter Drains, with a particular emphasis on the Scottish Trunk Road Network
… the complex inter-relationship between catchment characteristics, road dynamics and the physical characteristics of the road to establish the key factors that govern the generation and spatial variability of Road-Deposited-Sediment (RDS). The aim being to establish the impact RDS …

Chironomid-based paleotemperature reconstruction of the North Slave Region, Northwest Territories during the Late Holocene
… records which may be due to site-specific catchment characteristics obscuring the regional chironomid-temperature signal. The significant Chan Lake temperature reconstruction had similar late Holocene climate events as other regional climate records, such as brief warming events throughout …

Optical Water Quality and Human Perceptions of Rivers
… between measured water quality and visible characteristics influencing human perceptions. Relationships among particulate concentrations as a function of the hydrograph during receding flow in five popular recreational rivers of the southwestern Ozarks of Arkansas, USA were dependent upon …

Dynamics of the atlantic salmon (Salmo salar L.) population of the River Foyle, Ireland
… salmon (Salmo salar L.) population of the Foyle catchment in Ireland, through the analysis of long-term datasets and extensive field data. In chapter 1 the current conservation status of the salmon is discussed with particular reference to the Foyle. Chapter 2 considers the interaction between …

Development and analysis of a homogeneous long-term precipitation network (1850-2015) and assessment of historic droughts for the island of Ireland
… to reconstruct river flows at twelve study catchments to 1850. Reconstructed flows are analysed to identify periods of hydrological drought and the potential of different SPI accumulations to forecast severe drought are explored. Results demonstrate the importance of catchment …

Biological assessment of tropical riverine systems using aquatic macroinvertebrates in Tanzania, East Africa
… variation within river types was driven by catchment characteristics such as geographical location, geology, altitude and local characteristics such as active channel width, proportions of boulder, cobble and sand on the bottom, influenced reference conditions in all three river types. …

Improving Predictions of Stormwater Quantity and Quality through the Application of Modeling and Data Analysis Techniques from National to Catchment Scales
… from wash-off of accumulated pollutants from catchment surfaces during runoff events. However, it assumes concentration is constant across events from a particular land use and several studies found little to no correlation between constituent concentrations in stormwater and ADP. …

Aqueous carbon losses from the Glenfeshie Mòine Mhór
… further the understanding of the variations in catchment characteristics and water chemistry between eight streams monitored on the Mòine Mhór plateau.<br/><br/>Through a nested design to capture data using continuous monitoring systems, grab sampling and flow monitoring, the hydrology of the …

A multifaceted analysis of diurnal streamflow patterns through the application of advanced analytical tools
… the complex dynamics of water flow within a catchment is fundamental to effective water resource management. This understanding involves robust knowledge of the catchment's hydrological and physiographical features. It requires a profound grasp of the spatiotemporal variability in a …

The phosphorus transfer continuum under climate change
… I use the three National Demonstration Test Catchment (DTC) platforms (Eden, Cumbria; Wensum, Norfolk; and Avon, Hampshire) which are representative of typical catchment typologies and agricultural activities in the UK to frame this work. Potential changes to the P transfer continuum are …

The prospects for stormwater harvesting in Cape Town, South Africa using the Zeekoe Catchment as a case study
… water resource - selecting the 89 km2 Zeekoe Catchment situated on the southern part of Cape Town as a case study. The study assessed potential to supply partially treated stormwater to non-potable water needs or fully treated water to potable water demands. The study determined that there was …

Extreme events in geoarchives
… sediment is mainly driven by runoff amplitude, catchment sediment availability and episodic sediment input by local sediment sources. A further role plays the lake internal sediment distribution which is not the same for each event but is favoured by flood duration and the existence of a …

Sediment transport modelling at the catchment scale in Alpine streams
… to enhance sediment transport modelling at the catchment scale. In particular, the present work aims at the evaluation of the efficiency of the CASCADE basin-scale sediment-transport model and its sensitivity to the local hydro-morphological conditions; to evaluate the distance from the …
