Accumulation, transport and potential treatment of surface sediment on car parks with channel drains

Barlow, James Vincent (Cranfield University, 2015-11)

Urban pollutants have been identified as a significant source of environmental pollution, posing a risk to human health, the environment, and are toxic to flora and fauna. Highways are recognised as one of the key sources ...

Application of integrated models to assess the impacts of floodplain connectivity on ecosystem services: a case study at Tempsford, UK

Taktikos, Niko (Cranfield University, 2015-09)

Floodplains in the United Kingdom have evolved from natural landscapes to artificially modified ecosystems through managing lateral and vertical floodplain connectivity leading to synergy or trade-offs in ecosystem service ...

Assessing the impacts of drought on UK wheat production

Clarke, David (Cranfield University, 2017-01)

Water limitations typically reduce UK wheat yields on average by 1-2 t ha- 1 , although this can be considerably more in extreme drought years. With the frequency and intensity of droughts expected to increase under a ...

Characterising urban catchments for explaining storm runoff and application in UK flood estimation

Miller, James (2019-02)

The impacts of urbanisation on catchment hydrology have been the focus of investigation over the last few decades, but quantifying and predicting the impacts remains an ongoing area of active research. One such area has ...

Development and application of runoff model for ater harvesting in North East Nigeria.

Audu, Idriss (1999-12)

Rainfall in the northeast arid zone of Nigeria is limited and has been found to be declining over the last three decades (Hess et al., 1995). This problem of inadequate rainfall is further exacerbated by runoff especially ...

Effect of greenspaces on soil hydrology within urban ecosystems.

Piwuna, Raulatu Munidang (2016-09)

Urban greenspaces provide a regulatory ecosystem service for some of the hydrological processes within urban ecosystems. However, soil hydrological properties can vary with variations in urban vegetation type having an ...

Evaporation in fen wetlands

Kelvin, J. (Cranfield University, 2011-06)

Wicken Fen represents a remnant of the once extensive peat fenlands of East Anglia, which survived large-scale drainage efforts intended to bring land into agricultural production due to its importance within the local ...

Impact of infield irrigation management by Botswana cabbage farmers on soil salinity

Molatakgosi, Goitsemodimo (Cranfield University, Cranfield University at SilsoeCranfield University at Silsoe, 2006-11-08)

Some vegetable farmers in the semi- arid Botswana are struggling or closing down their enterprises citing the cost of irrigation and salty water as the problem. Irrigation with water from the salt-laden underground water ...

Impacts of irrigation heterogeneity on sugarcane yields, energy and water use in sub-saharan Africa.

Banda, Mavuto Muhammad (Cranfield UniversitySWEE, 2023-12)

Sugarcane is an economically strategic crop in Sub-Saharan Africa (SSA), underpinning the rural livelihoods and economies of many SSA countries. Despite its economic importance, yield trends in the region have been ...

The influence of catchment characteristics on river flow variability

Chiverton, Andrew (Cranfield University, 2015-08-05)

Hydrology is yet to fully understand the role that catchment characteristics have in determining a river’s response to precipitation variability. This thesis assesses the influence that catchment characteristics have on ...

Microtopographic enhancement of land-based wastewater treatment

Tyrrell, Sean R. (Cranfield University, 2016-09)

There is a regulatory tension within wastewater treatment, between the requirement to meet tightening consents and the need to reduce the carbon footprint of treatment processes. With 75% of wastewater treatment ...

Modelling catchment scale response to drought risk, a case study in South Africa.

Lulane, Zanele (2021-09)

South Africa is a water scarce country with future water availability threatened by climate change, an increasing population leading to urbanization, increasing agricultural production, and industrialization. Past droughts ...

Modelling phosphorus removal capacity and longevity in land treatment systems.

Batista Segui, María del Mar (2017-10)

The wastewater industry is facing an increase in regulatory pressure to reduce excessive phosphorus (P) release to rivers. To address this issue there is a need for sustainable treatments, especially in small sewage ...

Modelling the impact of climate change on avocados future irrigation requirements in South Africa

Mendori, Thomas (2021-09)

Climate change will affect worldwide weather and crop development. Agriculture is a major concern around Groot Letaba catchment (South Africa), and future irrigation supply for avocado crops is at risk but remains unclear. ...

Modelling the impacts of in-field soil and irrigation variability on onion yield

Perez Ortola, Marta (Cranfield University, 2013-11)

Globally, onion (Allium cepa L.) represents an extremely important crop in terms of production, value and consumption. Similarly, in the UK onion production is considered to be one of the most important high-value field ...

Optimising nutrient potential from compost and irrigation with wastewater to meet crop nutritional requirements

Chipula, Grivin (Cranfield University, 2013-04)

Globally agricultural production is facing serious challenges to provide adequate food supply to meet a growing population. However, the reduced capacity of soil to support and sustain agricultural production as a result ...

Processes controlling the sources and transport dynamics of suspended sediment in rivers

Vercruysse, Kim (2017-09)

Human activity has disturbed the natural suspended sediment (SS) balance and the associated geomorphological and ecological functioning of many rivers. Yet, predicting and managing SS is challenging because the processes ...

Reedbed hydrology and water requirements

Peacock, Catherine (Cranfield University, 2003-02)

Stodmarsh National Nature Reserve includes the largest reedbed in Southern England and is an important habitat for breeding waders and several rare bird species, including Bitterns. A succession of drought years in the ...

Soil variability effects on the yield of winter wheat under variable-rate nitrogen applications

Miles, Daniel (Cranfield University, 2016-05)

Seven UK fields located across Oxfordshire, Southampton and W. Berkshire, five cropped in winter wheat in 2014 and two in 2013 were investigated to assess the effect of soil variability on mean yield and yield variance ...

A study of obesity drivers in Mexico using alternative future scenarios to define policy,

Anguiano Arreola, Paulina (Cranfield UniversitySWEE, 2022-02)

In the last four decades, Mexico has experienced a rise in the prevalence of obesity among urban households, increasing the risks of comorbidities and premature deaths. This PhD thesis examines what is driving obesity ...
