Morphology of the Southern North Sea Coast from Cape Blanc-Nez (F) to Den Helder (NL)
The southeastern North Sea coast of France, Belgium and the Netherlands (up to Den Helder) is characterized by coastal dunes, sandy beaches and a shallow, gently shoreface. In the Delta...

Coastal Morphological Modeling for the Southern North Sea
The paper gives a inventory of mathematical model concepts for coastal morphological applications, from sophisticated short-term process models based on first physical principles, via...

Planning and Implementation for Sustainable Management of Negombo Lagoon, Sri Lanka
The author narrates how an organized, poor and relatively marginalized set of coastal communities in Sri Lanka have, by collaborating with state agencies and establishing informed dialogue,...

Modified Horton Models for Steady Rainfall
When the rainfall rate is less than the initial infiltration rate, direct application of the well-known Horton equation underestimates the total volume of water infiltrating the soil until...

A Statistical Climate Inversion Scheme and its Application in Hydrologic Impact Assessment Studies Associated with Global Climate Variability
The use of deterministic atmospheric, general circulation models (GCM's) to understand potential global climate change under doubled CO2 forcing...

Flash-Flood Forecasting by Using the HEC1F Model
The application of a lumped conceptual model, the well known HEC1F, for flash-flood forecasting and warning to the Venetikos river basin in Northwestern Greece, is presented. The combination...

Combining Orographic Precipitation and Runoff Models for Improving Reservoir Operations
This paper reports on a study being conducted by the Bureau of Reclamation whose end objectives are improved quantitative precipitation forecast (QPF) for use in hydrologic runoff models...

Modeling Wetland Hydrologic and Hydraulic Processes
Water availability and the processes by which it moves are critical to a wetland's success, where success is measured in terms of the quantity and quality of functions provided by the...

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...

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...

Stochastic Modeling for Drought Analysis Using Thomas-Fiering Lognormal Three Parameter Model
Three variations of Thomas-Fiering log normal 3-parameter(TFLN3) model are fitted to the unregulated south-west monsoon-dependent monthly streamflows measured at Krishnarajasagara (KRS)...

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...

Water Quality Modeling of Lower Green Bay
The impact upon water quality of the planned expansion of a confined disposal facility (CDF) located in lower Green Bay was studied using numerical hydrodynamic and water quality models....

Unit Hydrograph Estimation Procedures Using Orthogonal Functions
All unit hydrograph estimation procedures based on orthogonal functions are reviewed in this paper. A more physically based orthogonal function (a gamma function) for unit hydrograph estimation...

Mathematical Models for Reservoir Routing Analysis
Various mathematical models exist for the analysis of reservoir flood routing problems. This paper compares recent Runge-Kutta and Euler numerical techniques with the well known Puls approach...

A New Look at the Statistical Estimation of PMP
The statistical base of Hershfield's Kmvalue Method and its application for estimating Probable Maximum Precipitation (PMP) were reviewed. The mathematical...

Fate/Transport Modeling of Immiscible LNAPL in Unsaturated Aquifers
In the past ten years since enacting CERCLA and SARA regulations there is a lack of model to adequately address the fate/transport of immiscible constituents in groundwater systems. This...

3D-Simulation of the Twin Lake Tracer Test
The 1983 Twin Lake tracer test was simulated using a three-dimensional finite element model. The model was calibrated comparing calculated and measured piezometric heads as well as vertical...

A Review of Surface-Groundwater Interaction Models
Surface-water and groundwater systems are in continuous dynamic interaction. Processes such as infiltration from surface waters and precipitation, the discharge of groundwater to surface...

Real-Time Dynamic Flood Routing with NWS FLDWAV Model Using Kalman Filter Updating
Dynamic flood routing model based on the four-point implicit finite-difference solution of the complete one-dimensional Saint-Venant equations of unsteady flow are inherently deterministic....
