Hydrology of Wetland Treatment Systems in East Orange County, Florida
Wetlands are increasingly being used as final treatment systems for industrial and domestic wastewater effluent discharges and stormwater runoff discharges. Hydrological monitoring and...
Ecohydrological Processes in Almost Flat Wetlands
In spite of their modest relief almost flat wetlands are able to maintain definite topographically driven groundwater flow systems. Large seepage areas create ecohydrological gradients...
Wetland Hydrology Management in Australia
Changes to the hydrologic regime of wetlands is a vital factor affecting the natural diversity and conservation values of wetlands. The management of wetland hydrology thus forms an integral...
Hydrologic Runoff Models for the Arid Southwest United States
Recently, hydrologic study criteria manuals (or hydrology manuals) were prepared for the arid southwest regions of Clark County (Las Vegas vicinity, Nevada), Maricopa County (Phoenix vicinity,...
Lag Relations for Semi-Arid Regions and Urban Areas
The use of synthetic unit hydrographs often requires the estimation of lag or other travel time parameters. Several procedures are available for estimating such unit hydrograph parameters....
Infiltration into Thick Unsaturated Alluvial Deposits: A Preliminary Study
An infiltration and dye transport study in an unsaturated alluvial deposit was conducted using a square flooding type infiltrometer over a 50 hour period. Red and blue dyes were added...
The Use of Residence Time to Describe a Hillslope
Queueing theory has been applied to the determination of Soil Water Residence Time (SWRT) using an 18 year data set. The calculated SWRTs agree qualitatively with the lags exhibited by...
Hydrologic Modelling of Extreme Flood on Small Mountainous Watersheds
Statistical and deterministic methods for extreme flood estimation were applied to Swiss alpine catchments to assess the application limits of each approach. Comparative results produced...
Linking Hydrologic and Hydraulic Routing Models in Low Relief Basins of South Florida
Combined use of hydrologic and hydraulic routing models to analyze the rainfall-runoff processes during a storm event is a common practice. In this approach, a hydrologic model is employed...
Back to the Unit Hydrograph Method
In this paper, the basic single area unit hydrograph model is shown to represent a highly complex, rational, link-node model which includes (i) variable effective rainfall distributions...
A Potential Problem with Mean Dimensionless Hydrographs at Ungaged Sites
A flood hydrograph for an ungaged stream site can be estimated from a mean dimensionless hydrograph and estimates of instantaneous peak discharge (Q) and total storm runoff volume (V)....
Minimum Streamflow Assessment in Italian Scenarios
Overall water availability and acceptable carrying capacity seem to be at their limits today in Italy. A specific procedure aiming at minimum streamflows analysis and evaluation has been...
Statistical Analysis of Extreme Hydrological Droughts
The study examined several works about extreme droughts for their validity with different parameters by the statistical experimental method. The results showed that the analytical method...
Variance Estimation of Extreme Flows
The inclusion of historic flood data with gage record data has been shown to reduce the uncertainty in flow estimates. Using numerical integration to quantify that uncertainty is less...
Peaks Over Threshold Model for Seasonal Flood Variations
The peaks over threshold (POT) series model has been used in hydrology to analyse extreme phenomena such as floods or precipitation amounts exceeding a certain threshold level. The results...
Robust Estimators in Hydrologic Frequency Analysis
This paper applies a specific robust estimation procedure known as 'trimming' in flood frequency analysis. The trimming technique consists in censoring the series of recorded floods by...
Incorporating GIS Technology in Standard Flood Hydrology Applications
The potential for application of Geographic Information Systems (GIS) to hydrologic analyses has received increasing attention in recent years. Published literature on hydrologic applications...
A GIS Application to Hydrology
This paper illustrates an application of Geographic Information System (GIS) in estimating input parameters for Penn State Runoff Model (PSRM), a watershed rainfall-runoff simulation model....
Irrigation, Agrichemicals and the Environmental Impact, the Role of Hydrologic Non-Point Source Models
The importance of pollution loads from agricultural lands and the degradation of soils and water resources has brought about extensive efforts throughout the environmental and agricultural...
Dynamic Perspective on the Capillary Barrier Effect at the Interface of an Upper Fine Layer with a Lower Coarse Layer
The theoretical principles behind the determination of infiltration rate into a coarse layer overlain by a tight layer are reviewed. As a descending unsaturated wetting front hits the...
