Towards a Rainfall Estimation Using Meteosat Over Africa
The scope of the research is to develop a method of rainfall estimation at both small space and time scales (9 pixels -225 km2-, and single shower...
Water Quality Study in an Arid Region Lake: Lake Bosten, Northwest China
This paper gives a brief description of Lake Bosten, its importance to Xinjiang Province of the PRC, objectives of an on-going study, and some preliminary results. This on-going study...
Soil-Moisture Flux Studies on the Nevada Test Site A Review of Results and Techniques
Over the last 20 years, numerous studies of soil-moisture flux and/or ground-water recharge have been conducted on the U.S. Department of Energy's (DOE) Nevada Test Site (NTS)...
Vertical Transport in the Vadose Zone by Fingering
Water containing contaminants may infiltrate through the vadose zone as a series of fingers which result from a hydrodynamic instability initiated at an interface in which a fine textured...
Nitrate and Bromide Transport Through a Vadose Zone in New Jersey
Ongoing field experiments on monitoring transport of Sodium Nitrate and Potassium Bromide in the vadose zone over a shallow groundwater table in the coastal plains of New Jersey are discussed....
Thermal Plumes from Staged Diffusers into a Uniform Quiescent Environment
The behavior of thermal plumes from staged multiport diffusers was investigated experimentally. The three-dimensional temperature distribution was measured by scanning thermistor rakes...
Chemically-Enhanced Treatment: An Alternative to Biological Secondary Treatment for Ocean Outfalls
Chemically-enhanced treatment is a process whereby chemicals are added to wastewater in order to enhance solids removals through coagulation. This treatment process can obtain removal...
An Experimental Study of Oil Spreading in Ice Covered Waters
In this paper the experimental procedure and some preliminary observations from a new series of experiments on the mechanism of oil spreading under fragmented ice are presented. Laboratory...
Task Committee on Transport Processes at the Interface of Water Column and Bottom Sediment
The Task Committee on Transport Processes at the Interface of Water Column and Bottom Sediment was formed on October 1, 1989 under the Technical Committee on Hydrologic Transport and Dispersion...
A Review of the State-of-the-Art in Sediment-Water Column Interaction Measurement Techniques
This paper reviews the state-of-the-art measurement techniques available to water quality modeling practioners to estimate: (a) sediment oxygen demand rates, (b) sediment-water column...
The Effect of Grain Size Distribution on the Entrainment of Interstitial Water into Overland Flow
Non-point source pollution from agricultural runoff is an important environmental problem. This experimental study considers the effect of media heterogeneity on the entrainment of interstitial...
A Mathematical Model for Transport and Mixing of Oil Slick in Rivers
A two-layer two-dimensional mathematical model for transport and mixing of oil in rivers is presented. In this model, oil in the river is considered to consist of a surface slick moving...
Soluble Pollutant Enrichment in Snow Covers
A mathematical model is presented to simulate enrichment of soluble pollutants in snow covers. The model is based on the liquid water flow, heat transport, and pollutant transport equations....
In-Stream Thermal-Regime Analysis for Powerplant Coolant Dispersion
A steam-tube dispersion model has been adapted to real-time simulation of heat dispersion in a 7-mile reach of the Des Plaines River below Joliet Power Station. Direct feedback control...
CORMIX2: Expert System for Multiport Diffuser Discharges
The Cornell Mixing Zone Expert System (CORMIX) is a series of software systems for the analysis, prediction, and design of aqueous toxic or conventional pollutant discharges into watercourses,...
Integration of GIS, Remote Sensing, and Digital Elevation Data for a Hydrologic Model
The Agricultural Nonpoint Source Pollution Model (AGNPS), which was developed by Agricultural Research Service, was used as a test model for assessing nonpoint source pollution. The model...
Major Sedimentation Issues for the USGS
Historically, sediment information has been used primarily in planning for engineering structures that were designed to meet a single or a very limited number of objectives. Today most...
Measurement of Hydraulic and Environmental Effects of Aeration Devices in Douglas Reservoir
The releases from Douglas Reservoir experience periods of low dissolved oxygen (DO) content during the summer months. Tests were conducted during August 1989 to determine the effects of...
Sacramento's Proactive Stormwater Permit Program
In January 1990, with the encouragement and assistance of the California Regional Water Quality Control Board-Central Valley Region (Regional Board), the City and County of Sacramento,...
