HOW URBAN DEVELOPMENT CONTRIBUTES TO THERMAL ENVIRONMENT VARIATION ---- A CASE STUDY IN NEW YORK CITY
… to accurately measure over heterogeneous land surfaces. Here, relying on remote sensing technology and meteorological models, AHF is estimated and illustrated on April 18, 2017 over NYC area. Furthermore, a few independent variables are developed in order to possibly explain the variations of …

Simulating urban growth for Baltimore-Washington metropolitan area by coupling SLEUTH model and population projection
… for the Baltimore-Washington metropolitan areas. In the first approach, we implemented traditional SLEUTH urban simulation model by using publicly available and locally-developed land cover and transportation data. Historical land cover data from 1996, 2001, 2006, and 2011 were used to …

A Comparison of Imperviousness Derived from a Detailed Land Cover Dataset (DLCD) versus the National Land Cover Dataset (NLCD) at Two Time Periods
… Cover Dataset (NLCD), this case study compares impervious surface from the NLCD to a Detailed Land Cover Dataset (DLCD) for the Town of Blacksburg, Virginia over two time periods (2005/2006 and 2011) at spatial aggregation scales (fine to coarse) and scopes (site-specific to area-extent). When …

Designing With Climate: Using Parking Lots to Mitigate Urban Climate
Urban areas are known to have different climatic conditions than their rural counterparts including higher temperatures, greater wind speeds, and increased precipitation otherwise known as urban heat islands, urban wind, and urban precipitation. These phenomena are all caused by the design and form …

Inventory and analysis of proprietary, small-footprint storm water best management practices
… of poor water quality in America. Increased impervious surface area due to new buildings and roadways means more water discharging when it rains and thus, more pollutants entering the receiving water bodies. One of the main pollutants of concern in storm water discharge is Total Suspended …

Hydrologic-hydraulic modeling for the dual drainage and flooding study of the Lawrence Avenue Underflow Sewer System
… cities where the urban development increases the impervious surface area which causes the runoff to exceeds the capacity of the drainage system. In the city of Chicago, the Lawrence Avenue Underflow Sewer System (LAUSS) is the first tunnel system built with the intention to capture and store …

A Spatial and Multivariate Approach to Examining Effects of Urbanization on Nitrogen Sources, Organic Matter Inputs, and Trophic Structure in Streams of Cobb and Paulding Counties, Georgia.
… a shift in the food web towards omnivory. Use of impervious surface area, land cover land use and ẟ<sup>15</sup>N to monitor water quality could provide an early indicator for stream degradation.</p>

A multi-city analysis of the natural and human drivers of the urban heat island
… in temperature relative to the surrounding rural areas, called the urban heat island, which can have negative impacts on the health and wellbeing of urban dwellers. This study uses a novel approach of analyzing a large number of cities from around the world to investigate the similarities and …

Linking the effects of land use change with water quality and discharge: an integrated approach
… to water quality. The Cub Run watershed study area, located in northern Virginia experienced significant land use change between 1979 and 1988. Two aspects of development, impervious surface area and construction activity, that impact discharge and water quality were quantified. Developed land …

The influence of urbanization on runoff generation and stream chemistry in Massachusetts watersheds
… In addition, I evaluate the importance of surface versus subsurface flow paths during rainfall events in stormflow generation in a small urban catchment. The percentage of residential land explains 52% of the variability in mean annual nitrate (NO3) concentrations in headwater catchments of …

Impervious Surfaces Mapping Using High Resolution Satellite Imagery
In recent years, impervious surfaces have emerged not only as an indicator of the degree of urbanization, but also as an indicator of environmental quality. As impervious surface area increases, storm water runoff increases in velocity, quantity, temperature and pollution load. Any of these …

Development of a Hydrologic Model for an Urban Headwater Stream: The Influence of Pervious Surface Properties on Runoff Dynamics
… urbanization (over 90% developed, and almost 50% impervious surface area (ISA)). Selected datasets provided information on the stormwater drainage network, the physical attributes of the catchment and receiving waterway (i.e. drainage area, slope, etc.), infiltration potential of soil map units, …

Managing the Water Quality of the Zandvlei Estuary using Sustainable Drainage Systems in the Diep Catchment
… catchments. Additionally, the increased impervious surface area associated with urbanisation has caused a significant rise in runoff volumes and runoff rates in the stormwater drainage systems. In South Africa, stormwater drainage systems conventionally channel everything they collect …
