Feasibility of Satellite Water Tanks for Urban Areas in Developing Countries
An intermittent distribution system delivers water to the end users for limited hours on certain days. End users often rely on service pumps, private tanks and on-site filters to cope with the unreliable low quality water supply. These coping mechanisms lead to uneven distribution of the already …

Time characteristics of small watersheds in response to the probable maximum precipitation
<p>"The EPA Storm Water Management Model (SWMM) was used to perform single event simulations of Probable Maximum Precipitation (PMP) level rainfall events on the Loss Lake watershed in southcentral Missouri. Overland flow was simulated using kinematic wave routing and channel flow was simulated …

Non-perennial streamflow & geomorphic patterns in a semi-arid rangeland slated for development
… data were reviewed to determine what storm events did, or did not, trigger a flow response. After over two years of stream channel monitoring, one precipitation event with a total depth of 92-mm and maximum 60-minute intensity of 50-mm per hour triggered streamflow. Additionally, a …

Development of a SWMM-GIS Flood Model for New Orleans Drainage Pumping Station No 4 Basin
An urban flood damage model for the drainage area serve by Pump Station No. 4 (Prentiss, New Orleans, Louisiana) has been completed. This study presents the research effort needed to develop a stormwater management model (SWMM) integrated with GIS that includes a Damage Model to estimate the losses …

Development of a Hydrologic Model for an Urban Headwater Stream: The Influence of Pervious Surface Properties on Runoff Dynamics
<p>A hydrologic model was developed for the Mullins Creek (MC) catchment located on the University of Arkansas campus in Fayetteville, Arkansas. The MC catchment is a small, dynamic urban stream system with a range of land use/land cover (LULC), an extensive and well-developed stormwater drainage …

Hydrologic and hydraulic modeling of the Lawrence Avenue Underflow Sewer System
… issues that are likely to occur during extreme storm events. The Lawrence Avenue Underflow Sewer System is characterized by unsteady flow conditions along with lack of geometric and spatial information of the pipe sewer network. This study herein focuses on the analysis of the system through the …

The viability of rainwater and stormwater harvesting in the residential areas of the Liesbeek River Catchment, Cape Town
The sustainable provision of water to South African citizens is a significant challenge facing the country. In order to avert a crisis, municipalities will need to reduce their reliance on traditional water sources. Rainwater harvesting (RWH) and stormwater harvesting (SWH) are two alternative …

How a dual drainage approach changes the examination of flood management infrastructure: a case study of the Chatham neighborhood of Chicago, IL
… conventional hydrologic & hydraulic simulation models such as the Storm Water Management Model (SWMM) can provide effective predictions about urban flooding, the development of dual drainage models (DDM) offers a unique opportunity to improve upon traditional methods. This study investigated the …

Impacts of Stormwater Management Practices and Climate Change on Flow Regime and Channel Stability
Urbanization increases runoff during storm events due to a reduction in vegetation and an increase in impervious surfaces, which limits the land's capacity to absorb and slow down water. This increase in runoff contributes to channel erosion. While extensive research exists on the hydrologic …

Modeling Climate Change Impacts on the Effectiveness of Stormwater Control Measures in Urban Watersheds
… progress in development of predictive models. Despite these recent advances, the assessment of CC impacts in urban watersheds remains an area of active research, in part due to the small temporal and spatial scales needed to adequately characterize urban systems. Urban watersheds have …

Using Geophysics and Terrestrial LiDAR to Assess Stormwater Parameters in Vacant Lots in Philadelphia
Managing stormwater volume and quality has become an important issue in urban hydrology. Impervious cover associated with urbanization increases surface runoff volumes and degrades the water quality of urban streams and rivers. Cities with combined stormwater and sewer lines such as Philadelphia, …
