Stochastic Modeling for Drought Analysis
Periodic as well as annual stochastic streamflow models have been fitted to the highly variable flows measured at Krishnarajasagara (KRS) on river Cauvery (Southern India), which is monsoon-dependent...
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...
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....
Uptake of Contaminants by Overland Flow
A mathematical model is developed for the uptake of contaminants by overland flow. The model is based on the numerical solution of the Navier-Stokes equations coupled with a two-equation...
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...
A Comparison of L-Moments with Method of Moments
A comparison of the Conventional Moments Method (CMM) with the L-Moments Method (LMM) for selecting a distribution is made. Five distributions GEV (Generalized Extreme Value), LNO (Lognormal),...
A Review of Fluid Movement in Compacted Clay: The Case of Macropore Flow
In constructing natural hydraulic barriers to infiltration, a typical design is one founded on the use of layers of compacted clay. Unfortunately, in analyzing the hydraulic performance...
Numerical Estimation of Macrodispersivities in Heterogeneous Self-similar Aquifers
Numerical simulations of contaminant transport in a stratified aquifer characterized by a self-similar distribution of hydraulic conductivity were performed. Macrodispersivities were calculated...
Non-Intrusive Crack Detection in Clay Landfill Cover Liners
Laboratory and field studies were conducted to demonstrate that the azimuthal variation in electrical resistivity can be used to indicate the presence of cracks in clay systems. Laboratory...
Simulation of the Propagation of Conserevative Contamination
The hydrodynamic model of the pollutant transport in water bodies was developed and adopted for Volga water supply system of Moscow, which includes five reservoirs and a channel. The model...
Lower Missouri River Water Quality Model for Evaluating Flow Alterations
A modified version of the US Environmental Protection Agency's (USEPA) one-dimensional (longitudinal) stream water quality model, QUAL2E, was applied to the lower Missouri River to evaluate...
Predicting Basin-Wide Tailwater Temperature Patterns by Combining Mechanistic and Statistical Water Quality Modeling
A simplified method for predicting water temperature patterns downstream of a peaking hydropower dam is described for the Fort Randall Dam tailwater of the mainstem Missouri River as part...
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....
