Rodewijk, N.H.N. (author)The TransAfrican Hydro Meteorological Observatory aims to create a dense weather station network in sub-Sahara Africa in order to obtain accurate climate data for a wide range of applications. Existing high-quality weather stations are very expensive and unaffordable for the African government or private parties. Therefore innovative sensors and...master thesis 2013

Van der Meer, C.G. (author)Pathogens are present in our urban water system, and may pose a health risk to swimmers and playing children. Although the knowledge of pathogens has increased over recent years, little is known about their behaviour in the urban water system. The goal of this thesis is to investigate this. First, the behaviour of pathogens under the influence...master thesis 2013

Van der Steen, A.J. (author)Introduction Dutch municipalities have a legal duty in groundwater management. Adequate and effective management of horizontal subsurface drainage systems is important in fulfilling this duty. The service life time of these systems have to be optimized. Financial resources should be used efficiently. Only since a few years there is a proactive...master thesis 2013

Meyer zu Schlochtern, A.N.H. (author)In the Upper Citarum Basin in Java, Indonesia, the Creative Policy Generation Method was used to study the applicability of the integrated Business Model Canvas (Osterwalder, 2010) and the creation track (Gray, 2010), which is a creative, solution-focused thinking theory. The goal in the Upper Citarum Basin was to create better, safer and more...master thesis 2013

Rutten, P.J.P. (author)Introduction The field of urban water management focusses on managing the (temporary) storages and flows of drinking, waste-, ground- , surface and storm water in urban environments. Adequate water management forms a prerequisite for pleasant living conditions . A difficulty urban water managers face is the limited or complete lack of control...master thesis 2013

Kooreman, B.D. (author)Satellite-based soil moisture measurements indicate a diurnal variation in backscatter in west Africa. This diurnal variation is assumed to be caused by variation of moisture content in vegetation (Friesen, 2008). The obtained satellite soil moisture data can be improved, if ground measurements support this hypothesis. Especially at locations...master thesis 2013

Dekens, B. (author)This thesis focusses on Dutch regional water systems. These systems are often low-lying polder-belt canal systems, where many pumps are needed to meet different requirements regarding water quantity and quality. The control of a complex water system, consisting of continuous dynamics (evolution of water flow and levels) and discrete elements (e...master thesis 2013

Eilander, D.M. (author)A new semi-supervised `growing' Bayesian classifier for small reservoir delineation has been developed and is tested with Radarsat-2 data for reservoirs in the semi-arid Upper East Region of Ghana. The classifier reduces the confusion error to the land-water boundary pixels, can readily be extended with auxiliary information and has a high...master thesis 2013

Van Emmerik, T.H.M. (author)Currently, vegetation is considered a barrier to soil moisture retrieval by both passive and active remote sensing missions. Microwave emission and backscattering of vegetation is driven by the vegetation dielectric constant, which is a function of vegetation water content. The latter is a measure of root zone water availability. Understanding...master thesis 2013

Meijer, L.J.J. (author)A continuous population growth and increasing energy demand combined with depleting traditional energy reserves puts a pressure on conventional methods of electricity generation. The desire and ambition to create a more sustainable society paves the way for the ‘renewables’. Hydropower or Hydroelectricity already plays a significant role in...master thesis 2012

Slingerland, J.D. (author)Urban areas are confronted with higher temperatures compared to rural areas during summer. Buildings, roads and paved surfaces store the heat during the day and then release it slowly during the evening keeping urban lands hotter than surrounding areas. This phenomenon is called Urban Heat Island effect and the differences can be up to 8°C. A...master thesis 2012

De Koning, M.K. (author)Artificial wetlands are used at different locations in the world as a treatment facility for wastewater of different composition. In order of Rijkswaterstaat several artificial wetlands are constructed for road runoff treatment. In all cases the artificial wetland is preceded by a sedimentation basin / storage buffer. One of them is located...master thesis 2012

Wagenaar, D.J. (author)Introduction Flood risks can be reduced by either reducing the probability or the consequences of a flooding. These consequences can be quantified with flood damage models. Such models determine flood damage based on the water depth and the land use. This thesis will investigate the need to also use the flood duration as input parameter. Problem...master thesis 2012

Pieron, M.M. (author)Capacity development has become an increasingly hot topic in the water sector. The development of individual, organisational, institutional and even societal capacities is argued to be required to be able to addressing the present-day water challenges. From a natural resources management context, much literature is available on WHAT is required...master thesis 2012

Van der Zwet, J. (author)There are plans for the construction of a multi-purpose dam in the White Volta River near Pwalugu in northern Ghana. The reservoir that will be formed should be beneficial for hydropower generation, irrigation and fishery. Up to now there has been no research into the morphological consequences of the creation of this reservoir. In this study...master thesis 2012

Zhang, B. (author)Located between the Andes Mountains and the southwestern coastline of Peru, the irrigation district of La Joya Antigua has a typical sub-tropical desert climate with very little annual precipitation. Study on this irrigation district shows sufficient irrigation water on most of the farms in a wet year but a deficit of irrigation water in a dry...master thesis 2012

Van der Pal, E. (author)Delta areas are attractive areas to live in. They are valuable due to their major economic potential as well as their large environmental values. However, due to ongoing urbanization, demand for space is still increasing and since delta areas are low-lying, they are vulnerable to flooding. Polders provide opportunities for further developing...master thesis 2012

Qian, H. (author)Introduction Gully pots or roadside catch basins are a common and important part of sewerage drainage networks. Their primary function is to retain larger solids from road runoff. They are used to minimize the problems associated with sediment in downstream drainage structures, pumps, treatment plants and receiving waters. Problem definition...master thesis 2012

Van Dieren, M.R. (author)Ongoing urbanisation and the subsequent extensive use of the urban water system can lead to degradation of its surface water quality. In the Netherlands, urban water bodies often suffer from the manifestations of eutrophication due to (historically) high nutrient loadings. This research focused on the enhancement of surface water quality of semi...master thesis 2011

Albers, B.C. (author)Since the end of the last century, polders in the Netherlands have suffered from inundation due to heavy rainfall. Inundation occurrences in 1998 have led to large economic losses, especially in polders with a fast rainfall runoff process due to the high percentage of land occupied by greenhouses. This thesis focuses on water system assessments,...master thesis 2011
