Water Measurement and Accounting of Lake Michigan Diversion
The diversion of water from Lake Michigan and the Lake Michigan Basin into the Mississippi River Basin has been regulated since the turn of the century. The U.S. Supreme Court Decree of...
Modeling Groundwater Flow in San Joaquin Valley
Water supply, reallocation and conjunctive use options, within the San Joaquin and Tulare basins of the Central Valley of California, are being considered by Federal and State Planning...
Identification of Aquifer Parameters in Confined Groundwater Flow
The logarithm of the aquifer properties, log transmissivity (log T) and log storativity (log S), are regarded as realizations of stochastic processes whose estimates are required. The...
Causes and Possible Control Measures of Flood in Bangladesh
Intensity and frequency of occurrence of devastating floods in Bangladesh have increased significantly over the past two decades. Large scale deforestation in the upstream reaches of Ganges,...
Streamflow Prediction and Allocation Model in Texas
The State of Texas' Water Rights Adjudication Act of 1967 provided for the creation of regional watermasters to divide the water of state streams in accordance with the adjudicated...
Data Collection Using a Portable Computer and Digitizing Tablet
This paper describes a data collection system developed by the New Hampshire Technology Transfer Center. The key features of this data collection method are its ease of use, single step...
Resistance Coefficient in a Tidal Channel
In applying a numerical hydrodynamic model to the tidal channel-lagoon complex around Great Sound, New Jersey, it became apparent that the model guidelines for the resistance coefficient...
Water and Sediment Quality Analyses for the New Boston Wastewater Outfall
This paper describes portions of the farfield hydrodynamic and water quality modeling conducted during preparation of the Boston Harbor Wastewater Conveyance System Supplemental Environmental...
Finite Element Analysis of Hillslope Variations in Surface Runoff
Watershed management decisions are aided through an accurate understanding of hydrologic processes. The finite element method applied to surface runoff with spatially variable hydraulic...
Application of RUSLE to Rangelands
The Universal Soil Loss Equation (USLE) has been revised to more accurately estimate soil loss from both crop and rangeland areas. Major revisions affecting rangeland soil loss estimates...
Comparison of ET Measured with Neutron Moisture Meters and Weighing Lysimeters
The neutron moisture meter (N.M.) method of determining crop water use is frequently used in research and irrigated agriculture. This study was conducted to compare crop evapotranspiration...
Simple Water Measuring Device for On Farm Irrigation Evaluation
Laboratory experiments were conducted for the calibration of three flumes of different sizes. The logarithmic transformation in linear regression yielded excellent results for the stage-discharge...
Delivering Appropriate Quantities of Water to the Farm
To study how well an irrigation district was able to meet farmer demand, water deliveries along two monitored lateral canals were compared to the orders and bills for these events. The...
Rehabilitation of Water Wells
The main causes of declining well yield are biological growths, mechanical clogging and chemical encrustation. Because the treatment of the causes of encrustation and clogging is expensive...
Calibration of Tensiometers and Gypsum Blocks Using Soil Moisture Content
The common tensiometer and gypsum block used for irrigation scheduling are evaluated using gravimetric soil moisture measurements. The results indicate several difficulties with the tensiometer...
Annual Flow Variations in the Nile River System
The annual flow series of the Nile River System at some key gauging stations for the period 1912-1988 are presented and discussed. The relatively stable period, pre-1961, has helped establish...
Flume Experiments on Debris Flow
With the different characteristics of grain motion in debris flow, three layers are vertically divided, i.e., viscous collision layer, inertial collision layer and suspension layer. Both...
Two-Dimensional Modeling of Overland Flow
Two-dimensional distributed finite element (F-E) and finite difference (F-D) models are developed to simulate storm events on arid watersheds. The F-E model uses the kinematic wave approximation,...
Operational Remote Sensing of Snow Cover in the U.S. and Canada
The Office of Hydrology of the National Weather Service maintains a cooperative National Operational Hydrologic Remote Sensing Center, based in Minneapolis, to generate remotely sensed...
Evaporation and Snowmelt Estimates from Satellite Data
Satellite imagery has been used to estimate saltwater evaporation and snowmelt runoff. Water surface temperatures can be obtained from satellite thermal infrared data. Saltwater evaporation...
