TLDR
In this article, the relationship between flood conditions and the spatial distribution of the urban development has been poorly studied, often because of limitations in streamflow data availability or the common use of lumped watershed models in urban hydrologic modeling.Abstract:
Urban development within a watershed can take on a wide and diverse range of spatial patterns. The terms “sprawl” and “clustered” development, for example, are frequent in the literature, spanning the spectrum of possible spatial patterns of urban development. The relationship between flood conditions and the spatial distribution of the urban development has been poorly studied, often because of limitations in streamflow data availability or the common use of lumped watershed models in urban hydrologic modeling. We study this relationship with an optimization-based approach that accounts directly for the spatial distribution of imperviousness to investigate how the urban spatial pattern will affect flood peaks and how it can be used to reduce or minimize undesirable impacts to water resources. We employ several water resources-based objective functions to perform optimizations that result in distinct spatial patterns of urbanization showing characteristics of both sprawl and clustered development, dependi...read more

Assessing the impact of urbanization on storm runoff in a peri-urban catchment using historical change in impervious cover
TL;DR: In this paper, the authors investigated changes in storm runoff resulting from the transformation of previously rural landscapes into peri-urban areas and found that the degree of area serviced by storm drainage was a stronger determinant of storm runoff response than either impervious area or development type and that little distinction in hydrological response exists between urban and periurban developments of similar impervious cover when no significant hydraulic alteration is present.

Analyses of urban drainage network structure and its impact on hydrologic response.
TL;DR: Meierdiercks et al. as mentioned in this paper used the Environmental Protection Agency's Stormwater Management Model (SWMM) for examining the impacts of urban drainage network structure on hydrologic response.

The impact of urban development on hydrologic regime from catchment to basin scales
TL;DR: In this paper, the role of urban spatial development on hydrologic response at both catchment (sub-grid) and river basin (between grid) scales in central Indiana was examined.

TL;DR: In this article, a model-based analysis is conducted in a typical urban residential catchment in Beijing, China, in which 69 subareas are delineated within the catchment as the basic drainage units.

Optimization by Simulated Annealing
TL;DR: There is a deep and useful connection between statistical mechanics and multivariate or combinatorial optimization (finding the minimum of a given function depending on many parameters), and a detailed analogy with annealing in solids provides a framework for optimization of very large and complex systems.

TL;DR: In this article, Naiman et al. pointed out that harnessing of streams and rivers comes at great cost: Many rivers no longer support socially valued native species or sustain healthy ecosystems that provide important goods and services.

Landscapes and Riverscapes: The Influence of Land Use on Stream Ecosystems
TL;DR: In this paper, the authors examined responses to land use under different management strategies and that employs response variables that have greater diagnostic value than many of the aggregated measures in current use.

Modern heuristic techniques for combinatorial problems
TL;DR: In this paper, the Lagrangian relaxation and dual ascent tree search were used to solve the graph bisection problem and the graph partition problem, and the traveling salesman problem scheduling problems.

The urban stream syndrome: current knowledge and the search for a cure

TL;DR: The term "urban stream syndrome" describes the consistently observed ecological degra- dation of streams draining urban land as mentioned in this paper, which can be attributed to a few major large-scale sources, primarily urban stormwater runoff delivered to streams by hydraulically efficient drainage systems.
