Effective Subsurface Retention/Detention Systems
Stringent environmental regulations and increasing land values have made finding an effective way to manage storm water runoff a high priority for consulting engineers and land developers....
Identification of a General Linear Model for Reservoir Inflows Forecasting
General linear stochastic models represent a valuable alternative to conceptual models in order to describe runoff generating mechanisms in a drainage basin. In regions such as Quebec,...
Water Quality Modeling of the Rouge River Watershed
A relatively detailed modeling framework for calculating pollution flows and loads to the Rouge River has been developed and tested successfully. The framework includes consideration of...
Sediment Removal from Stormwater Runoff
Sediment traps, also known as baffle boxes, are being used throughout the state of Florida to remove sediment from stomiwater. A baffle box is divided into three compartments by two bathers,...
Selection of the Form of Calculated Flood Hydrograph in Projecting Water Release Facilities
Traditionally, in evaluating hydraulic structures, river flood runoff hydrographs are determined by maximum flood water volume and discharge, duration of the flood and some other parameters,...
Runoff Forecasting Using a Local Approximation Method
Forecasting of hydrological events, particularly floods, is an important topic of concern for hydrologists. Flood hazards can be prevented or their effects minimized if prior warning of...
Alternative Urban Flood Control
The hydrological impact of urban growth on urban ecology, water resources, and specifically on urban flooding has been profound. Urban growth in Iran, assuming the continuation of past...
A California Handbook for Developing an Industrial/Commercial Storm Water Inspection Program
Runoff and non-storm water discharges to storm drains from industrial and commercial businesses can be major causes of storm water pollution in urban areas, but there are sources of this...
Subcatchment Parameterization for Runoff Modeling Using Digital Elevation Models
Numerical algorithms are presented to estimate the length, width and slope of rectangular planes representing irregularly shaped overland contributing areas defined on raster Digital Elevation...
A DEM Based Hydrologic and Sediment Transport Model
A DEM-based, physically-distributed model was developed for simulating event runoff and erosion on an agricultural watershed. Runoff was described using the diffusion equation with flow...
Effects of Spatial Data Resolution and Subarea Size on a Distributed Runoff Model
Spatial data layers of elevation, land use, and soils for a small agricultural watershed in Pennsylvania were used to study the effect of resolution degradation of raster data on the output...
Developing Parameters for a Quasi-Distributed Runoff Model Using GIS
The widespread availability of radar precipitation data is driving rainfall-runoff modeling from lumped-input to distributed-input methods. As a consequence, model parameterization is...
The Standley Lake Protection Project
Until recently, there has been no physical separation between potentially contaminated runoff from the former Rocky Flats Nuclear Weapons Plant and Standley Lake, the nearby water supply...
Stormwater Management for San Joaquin Hills Transportation Corridor, Orange County, California
San Joaquin Hifis Transportation Corridor (SJHTC or Corridor) is one of the largest design-build toll roads in U.S.A. To meet stringent environmental mitigation requirements, to ensure...
Distributed Hydrologic Modeling of Humid Regions
Distributed physically-based hydrologic modeling of humid watersheds with shallow soils is complicated by non-Hortonian runoff production mechanisms. This paper presents a numerical experimental...
Controlling the Impacts of Development on Storm Water Quality through Proper Site Planning and Design
Land development and construction activities can significantly alter drainage patterns, increase runoff peak flow and volume, and contribute pollutants to storm water runoff. Federal and...
Assessing Water Quality Impacts of Stormwater Runoff
Current water quality monitoring of non-point source runoff typically involves periodically measuring a laundry list of chemicals in the runoff waters. This approach, while satisfying...
Water Quality Mitigation for the San Joaquin Hills Transportation Corridor
The San Joaquin Hills Transportation Corridor (SJHTC) is a 24 km Design/Build tollway which has been financed with bonds to be paid back with toll revenue. The Environmental Impact Statement...
Immobilization of Metals and Solids Transported in Urban Pavement Runoff
Urban areas in North America continue to grow in size and population. With this growth is an increase in automotive traffic, roadway pavement and deleterious anthropogenic constituents....
Field Verification of Dem-Derived Watershed Response
Rainfall-runoff data from an NAEW Experimental Watershed are used to test the feasibility of deriving the watershed response from the digital elevation model of the watershed. Using Clark's...
