Estimation of Curve Numbers for Concrete and Asphalt
All impervious surfaces are assigned a Curve Number (CN) of 98. However, no field or experimental evidence exists (to our knowledge) that shows why the impervious CN was assigned a value...

Featured bridges are: Rion-Antirion Bridge (Greece); Menai Straits Bridge (UK); Firth of Forth Bridge (UK); Fred Hartman Bridge (TX); Kintaikyo Bridge (Japan); Arlington Memorial Bridge...
Progress Report: ASCE Task Committee on State of the Practice in Curve Number Hydrology
In response to a growing awareness of the role of the Curve Number method in engineering and environmental impact applications, and its limitations, the Committee was formed in late 1997,...
Re-Creating the Rainbow Bridge
A team of American and Chinese experts constructed a pier-free arch bridge in China based only on a 12th century...
Basin Response Time: Potential Hydrologic Basin Handprint
Hydrologic lead time is an important factor in many water resources engineering applications. The determination of the response time of a watershed to runoff-producing rainfall is the...
Practical Applications of Gage-Adjusted Radar?Rainfall Estimates
(no paper) It is radar's estimates of rainfall at a specific location that tends to disappoint. On the other hand, the strength of rain gage observations is in estimating rainfall at a...
Fuzzy Rule-Based Forecasting of Extreme Rainfall Probability Conditioned on Sea Surface Temperature
(No paper) The recent El Nino event demonstrated the importance of sea-surface temperature on rainfall anomalies. The purpose of this paper is to develop a methodology to forecast extreme...
Predicting with Precision
In many urban areas flood prediction systems are inadequate. Most rely on networks of widely dispersed rain gauges that often fail to provide sufficient geographic coverage to characterize...
Overflow Control
The city of Houston devised an innovative flow remonitoring effort that allowed engineers to modify or eliminate many planned overflow control facilities. Net construction savings topped...
Analysis of Exceptional Meteorological Conditions on July and August in Conakry
Conakry is a zone that receives more precipitation than other countries in West Africa. Sometimes the quantity is more than 4,000 mm per year. Strong rainfalls are observed between July...
Flooding from Rain-on-Snow Events in the Sierra Nevada
The most damaging floods in rivers of the Sierra Nevada of California have occurred during warm storms when rain fell in snow covered catchments. These large floods in the major tributaries...
Indianapolis Uses New Radar Technology to Refine Hyetographs for CSO Model and SSES Studies
Indianapolis is the first city in the country to install the French-developed technology designed by urban hydrologists to accurately measure rainfall between rain gauges. Installed in...
Streamflows Prediction Models for the Colombian Generation System Considering El Ni?o Effect
A monthly and a daily prediction models for some Colombian rivers with hydropower developments were developed and implemented. Several monthly streamfiow prediction models are presented....
Debris Flow Events at Mountainous Creeks near Santiago, Chile- Hydrologic Analysis
One of the most important aspects in relation to peak flows magnitudes generated in mountainous catchments at the western side of the Andes facing the city of Santiago, Chile (latitude...
Hysteresis Effect of Karst Vadose Zone in Spring Kr5, Mt. Kr?uterin, Austria
Hysteresis effect is considerable in Spring Kr5, involving a chain of processes of recharge-infiltration-discharge. The lag time of each process to another can be briefly summarized and...
Stormwater Management Plan Updated for Climate System Changes
When large watershed stormwater management plans are updated, climate system change factors due to global warming effects should be considered. Climate system changes may cause changes...
A Stormwater Management Plan
Part 2 of the National Pollutant Discharge Elimination System (NPDES) Stormwater Permit requires both sampling and analysis of stormwater and the control of illicit discharges to stormwater...
Rainfall-Runoff Modeling for Watershed Stormwater Management
In the design of watershed stormwater management plans used for land development, the Pennsylvania State Runoff Model (PSRM) presents upstream subbasin flows that contribute to the peak...
Preparation of Notification Models Using Continuous Modeling Techniques
Public health departments in many states now require that operators of collection systems notify them of discharges from combined sewer systems soon after these events occur. This allows...
