Simulation of Runoff and Infiltration of Disturbed Land
Disturbances of land due to human and natural causes change the porosity and hydraulic conductivity of the soil. A simulation model of conjunctive surface-subsurface flows can be used...
Agricultural Impacts on Surface Water via Ground Water
Three years of ground and surface water quality monitoring data collected from one site in the mid-Atlantic coastal plain are presented. These data suggest that delivery of P from ground...
Gradual Development of Bores in Canal Systems
Modern computer programs for modeling unsteady flow in open channels are typically constructed using a momentum conserving form of the Saint Venant equations. This allows computation of...
Case Studies of Semi-Closed Pipeline Systems for Flexible Deliveries
The semi-closed pipeline system using the best aspects of the open and the closed pipeline systems, has many applications. It is the best adapted system for use with the variable flow...
Darcy-Weisbach Roughness Coefficients for Selected Residue Materials
A laboratory study is conducted to measure Darcy-Weisbach roughness coefficients for corn, cotton, peanut, pine needles, sorghum, soybeans, sunflower, and wheat residue. Varying rates...
Calculation of Runoff from Rainfall Using NURP Data
Peak runoff flows and flood hydrographs are important elements in the design of drainage and flood-protection structures. The validity of methods for predicting peak flow from rainfall...
Honolulu Harbor Ship Traffic Simulation and Animation Study
A computer simulation and animation study was conducted to investigate the operational impacts of projected ship traffic increases and harbor reconfiguration specified in the Honolulu...
Ship Simulation of the Houston Ship Channel, Houston, Texas
The Houston Ship Channel (HSC) consists of approximately 65 miles of improved deep-draft channels. The present channel is 400 ft wide and 40 ft deep at mean low tide for most of the channel...
Modeling Instantaneous Residential Demands in Municipal Water Distribution Systems
A modeling scheme is proposed for simulating the intensity, duration, and frequency of instantaneous indoor water use at a single family residence. The intensity and duration of indoor...
Use of Interactive Simulation Environments for the Development of Negotiation Tools
Interactive computer programs have been used successfully for many years to facilitate the planning and operation of water resources. Recently, advances in computer software have made...
Estimating Urban and Suburban Sewage Flows with Assistance of GIS Technology
The Massachusetts Water Resource Authority (MWRA), an agency created by the Massachusetts legislature to provide wholesale water and sewer services to the metropolitan Boston areea, is...
Development of the San Fernando Basin Groundwater Flow Model
This paper describes the development and calibration of the San Fernando Basin (SFB) groundwater flow model. The SFB is the largest groundwater basin in the Upper Los Angeles River Area...
Optimization Model for Operation of Recharge Basins
A mathematical model is developed for the optimal operation of recharge basins, which is a non-linear optimization problem. The objective of the model is to determine the operation that...
Habitat Simulation in United States, Britain, and France
The need to identify an instream flow requirement for water resources management exists in a number of countries. The use of habitat simulation in the United States, Great Britain, and...
Are High and Low Flow Habitat Values Really the Same?
The Instream Flow Incremental Methodology calculates physical habitat as a weighted sum. Suitability of use information for each modeled species and life stage are used to weight each...
Three Dimensional Modeling of Watershed Hydrology
A three dimensional finite element numerical model is developed for the first order watershed hydrology using 8-noded isoparametric brick elements. The 3-D subsurface flow in a hillslope...
Indicator Variography for Spatial Characterization of Aquifer Heterogeneities
The qualitative information or soft data from lithologic descriptions is processed using a state-of-the-art geostatistical approach to delineate, with quantified uncertainty, the extent...
Calibration and Validation of the Storm Water Management Model to the Providence Area Combined Sewer System
This paper exemplifies the calibration and validation of the EPA Storm Water Management Model (SWMM) to one drainage area within the Providence (RI) area combined sewer overflow system....
Reservoir Operating Rules for Maximum Hydropower Production
A procedure for testing the effectiveness of reservoir operating rules for real-time, multi-purpose reservoir operation is presented. Particularly, models that may be used to achieve maximum...
Development of Storage Demand Relation for Reservoirs?A Probabilistic Approach
This paper presents a practical method for developing storage-demand relation for reservoirs by a probability analysis of the stream flow data. The method was employed by the author for...
