“…The recognition that the land in the immediate vicinity of the watercoursethe riparian area -has the most influence on the aquatic ecosystem has prompted many jurisdictions in North America to adopt guidelines -either mandatory (regulations) or recommended (best management practices)controlling land use along watercourses (Young, 2000;Blinn & Kilgore, 2001;Lee, Smyth, & Boutin, 2004). The outcome of these guidelines is the establishment of "riparian buffers", also called "streamside management implemented in agricultural landscapes also (Zhang, Liu, Zhang, Dahlgren, & Eitzel, 2010;Brinson & Eckles, 2011) and are advocated for improving stream health and water quality in urban areas (Urban, Skelly, Burchsted, Price, & Lowry, 2006;Day, Braioni, & Tezer, 2008).…”

Riparian buffers in North America usually have been designed to mitigate specific land-use impacts on watercourses, and thus often fail to preserve the full range of riparian ecological functions (e.g. wildlife habitat). This paper reviews the unique ecological characteristics of riparian areas in an attempt to formulate a widely applicable buffer delineation capable of maintaining most riparian ecosystem services. To avoid ambiguity, the watercourse is defined in terms of its high water mark, which includes flood-prone areas and adjacent wetlands. Published data on the spatial range of riparian functions indicate that the land within 50 m of the water edge interacts the most with the watercourse through exchanges of matter and energy. For maximum effectiveness, the riparian buffer should be continuous (across all types of land use, ownership, and jurisdiction) and its native vegetation preserved or restored. The delineation method has been applied using spatial analysis to a watershed in Nova Scotia, Canada. A 50-m buffer represents 15% of the watershed terrestrial area. Excluding timber harvest in this buffer decreases the total potential harvestable volume by 11% compared to provincial regulations and by 7% compared to the practices of the local forest-products company. The simplicity of the proposed riparian buffer delineation lends itself to easy implementation by any landowner with little training and cost, a distinct advantage considering the urgency of protecting freshwater ecosystems. Moreover, continuous buffers can serve as wildlife movement corridors throughout the watershed and are thus an essential component of connectivity planning at the landscape scale.

“…For example, shipping may induce reduced clarity and lead to collision risk to swimmers. Some trade-offs can be managed by temporal and/or spatial delineation of conflicting uses (Day et al 2008 ; Gemeente Amsterdam 2016 ). This strategy may also be implemented when human uses conflict with protection of ecological quality of aquatic ecosystems.…”

Improving suitability of urban canals and canalized rivers for transportation, thermal energy extraction and recreation in two European delta cities

Canals and canalized rivers form a major part of surface water systems in European delta cities and societal ambitions to use these waters increase. This is the first assessment of how suitability of these waters can improve for three important uses: transportation, thermal energy extraction (TEE) and recreation. We assess suitability with Suitability Indices (SIs) and identify which alterations in the water system are needed to improve SI scores in Amsterdam, The Netherlands, and Ghent, Belgium. The results show spatial variability in suitability scores. Current suitability for transportation is low (SI score = 1) to excellent (SI score = 4), for TEE fair (SI score = 2) to excellent (SI score = 4), and suitability for recreation is low (SI score = 1). Suitability could improve by enlarging specific waterway dimensions, increasing discharge and clarity, and by enhancing microbiological water quality. The same methodology can be applied to optimize designs for new water bodies and for more water uses.

“…As urban populations grow and cities face densification, the pressure on urban surface waters to be used for multiple human uses is increasing due to larger population numbers 12 and lack of space (Day et al, 2008). The type of use functions will likely also change due to urban redevelopment.…”

“…Identification of use opportunities in planning processes can help to prioritize use functions based on demand and potential supply. The priorities may guide temporal and spatial delineation of conflicting uses and guide investments (Day et al, 2008;Gemeente Amsterdam, 2016). Major investments are needed in high income countries to renovate water infrastructure in the next decades (UNEP, 2013); this provides a window of opportunity to optimize surface waters as part of this infrastructure for the desired use functions of the future.…”

Functional quality of urban surface water

The key urban water management concept is sustainable or integrated Urban Water Resources Management (UWRM). This concept promotes integration of water management and spatial planning for holistic management of all parts of the water cycle, including both natural and technical water infrastructure (Feilberg & Mark, 2016;Hering & Vairavamoorthy, 2018;Kirshen et al., 2018). The integration of water management and urban spatial planning is also advocated in the United Nations' New Urban Agenda (UN, 2017). Integrated management requires knowledge of each component of the water system (Mosleh & Negahban-Azar, 2021); surface water is one such component. To create This research is targeted at water-rich cities with relatively high water quality, such as in Europe and Northern America, because their surface water system can support a broad spectrum of water uses. The study areas for in-depth assessments in this thesis are the cities of Amsterdam in The Netherlands (Europe), Ghent in Belgium (Europe) and Toronto in Canada (Northern America). Amsterdam serves as study area in each phase of the research, while Ghent and Toronto are used as study area for specific research activities.The assessment of the current use of and future demand for urban surface water use functions is conducted for Amsterdam and Toronto. These cities are selected because they represent cities on different continents, with different climates and geographic characteristics, including different types of surface waters (Table 1.1). This variation broadens the relevance of this study. Amsterdam and Toronto are medium sized cities with respectively 854,047 and 2.96 million inhabitants. This is a relevant size class for studying urban surface water use and demand because most city dwellers in Europe and Northern America live in cities with a population of respectively 500,00 to 5 million inhabitants and 1 to 10 million inhabitants; this is expected to continue through 2030 (UN, 2019). In both cities, urban redevelopment leads to land use change and densification. Together with local water quality improvements, especially reductions of nutrient concentrations and faecal pollution (
