“…Pseudo 3D representation may be materialized by vertical hydraulic links that communicate two different layers of flow: a superficial one, corresponding to free surface channels and flooded areas; and a subterranean one, related to free surface or surcharged flow in storm drains. Some applications of MODCEL may be found in [7,[54][55][56][57].…”

Urban Floods in Lowlands—Levee Systems, Unplanned Urban Growth and River Restoration Alternative: A Case Study in Brazil

Abstract:The development of cities has always had a very close relation with water. However, cities directly impact land use patterns and greatly change natural landscapes, aggravating floods. Considering this situation, this paper intends to discuss lowland occupation and city sustainability in what regards urban stormwater management, fluvial space, and river restoration, aiming at minimizing flood risks and improving natural and built environment conditions. River plains tend to be attractive places for a city to grow. From ancient times, levees have been used to protect lowland areas along major watercourses to allow their occupation. However, urban rivers demand space for temporary flood storage. From a systemic point of view, levees along extensive river reaches act as canalization works, limiting river connectivity with flood plains, rising water levels, increasing overtopping risks and transferring floods downstream. Departing from this discussion, four case studies in the Iguaçu-Sarapuí River Basin, a lowland area of Rio de Janeiro State, Brazil, are used to compose a perspective in which the central point refers to the need of respecting watershed limits and giving space to rivers. Different aspects of low-lying city planning are discussed and analyzed concerning the integration of the built and natural environments. OPEN ACCESSSustainability 2015, 7 11069

“…The urbanization process lowers the infiltration rate by substituting impervious cover for natural vegetation, and increases in discharge rate are the direct result of high water velocity. These lead to increased vulnerability to urban flooding; moreover, these problems are even worse for developing countries since industrialization has concentrated the urbanization process in the past half century 54) . Considering these problems, flood control as a factor in watershed-based planning and land use analysis was categorized with two main purposes.…”

“…The objectives of this is to minimize the quality and quantity problems related to urban development's effect on the natural environment, and maximize amenities and biodiversity opportunities under different scenarios, considering distinct future urban development possibilities. The traditional approach distributes floods downstream at any time, while the distributed measures over the basin showed a high possibility of adaptation to the future urban pattern 54) . Ian McHarg's ecological planning approach based on hydrological properties related with land use change, storm water, runoff and discharge was evaluated for its effectiveness for flooding control, and the best solution among the development approaches compared in the study was identified 55) .…”

With increased awareness of the importance of land use change at both local and regional scales within watershed-based planning, the study of land use analysis has become the focus of several international scientific endeavors. Since land use change has become a major issue in this century due to global urbanization, the study of watershed-based land use analysis will play an important role in a sustainable future. This paper undertakes a comprehensive review of watershed-based land use analysis to clarify the research trends in this area, including basic tools, factors, methodologies, study regions, scales and areas. Land use detection methods, land use modeling and thresholds in watershed delineation were identified as the fundamental tools, while land use policies, water quality, surface runoff, flooding control, land use suitability and land allocation analysis, and landscape structure were identified as the main factors in watershed-based land use planning.

Urban flood modelling has been evolving in recent years, due to computational facilities as well as to the possibility of obtaining detailed terrain data. Flood control techniques have also been evolving to integrate both urban flood and urban planning issues. Land use control and flow generation concerns, as well as a set of possible distributed measures favouring storage and infiltration over the watershed, also gained importance in flood control projects, reinforcing the need to model the entire basin space. However, the use of 2D equations with highly detailed digital elevation models do not guarantee good results by their own. Urban geometry, including buildings shapes, walls, earth fills, and other structures may cause significant interference on flood paths. In this context, this paper presents an alternative urban flood model, focusing on the system behaviour and its conceptual interpretation. Urban Flood Cell Model-MODCEL is a hydrological-hydrodynamic model proposed to represent a complex flow network, with a set of relatively simple information, using average values to represent urban landscape through the flow-cell concept. In this work, to illustrate model capabilities, MODCEL is benchmarked in a test proposed by the British Environmental Agency. Then, its capability to represent storm drains is verified using measured data and a comparison with Storm Water Management Model (SWMM). Finally, it is applied in a lowland area of the Venetian continental plains, representing floods in a complex setup at the city of Noale and in its surroundings.
