Impact of Sedimentation Caused by Runoff
As water is pumped into a reservoir, sedimentation caused by runoff can be an important factor in the reservoir's storage capacity. This report discusses various studies conducted...
Annual Delivery Decisions in the Simulation of the California State Water Project and Federal Central Valley Project using DWRSIM
This paper presents a new annual contractor delivery determination procedure for the California Department of Water Resources' State Water Project (SWP) and Central Valley...
Drought Management in Northeastern Colorado
The Northern Colorado Water District (the District) has established a set of policies and procedures and constructed a water storage and distribution system that allows for the effective...
Drought in California: When Does It Begin and When Does it End?
California recently endured a six-year period of drought. While the public, media and control agencies like simple definitions to classify water conditions, in a state as large and varied...
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...
Estimation of the Probable Maximum Rainfall and Snowmelt Floods Via Physically Based Model of River Runoff Generation
Disastrous floods can be caused by unusual combinations of hydrometeorological factors and river basin conditions that have not been observed during a long observation period. The physically-based...
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...
Identifying Trends from Streamflow Records?A Case Study
Historical streaniflow records for the Ruby River, in southwestern Montana were analyzed for trends and for changes in the precipitation-runoff relationship. Trends were first identified...
Managing Border Irrigation for Near-Zero Discharge
A dimensionless database of previously executed simulations of sloping-border irrigation with tailwater runoff constitutes the heart of design-aid software showing the effects on runoff...
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...
Direct Sizing of Small Stormwater Pump Stations
Pump stations are components of stormwater drainage systems that remove collected storm runoff from locations where drainage by gravity is not feasible. Usually pump stations will operate...
Development of the San Joaquin County Hydrology Manual
A hydrology manual was prepared for the County of San Joaquin, California for the determination of storm runoff quantities for the design of flood management facilities, floodplain analysis,...
Searching for Optimal Combinations of Stormwater Detention Basins
Hydrology of urban areas is dominated by two distinct characteristics: (1) a preponderance of impervious surfaces created primarily by pavement and roofs, and (2) the presence of constructed...
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....
