Sediment Transport Models for Small Gullies in Loess Hill and Gully Regions
Three items are studied: the equation of the relation between discharge and sediment for small gullies derived by using the theory of river dynamics; the extension of the Nash theory of...
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)...
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....
The Sorry State of Flood Hydrology in the Arid Southwest
Flood hydrology for urban areas of the arid and semiarid Southwest is in a sorry state. It is based in large part on precomputer manual methods. The state-of-the-art should move into the...
Complex Geomorphic Response to Minor Climate Changes, San Diego County, CA
Precipitation in San Diego County, California over the past several hundred years has been characterized by excursions between periods of relatively low precipitation having durations...
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...
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...
Uncertainty of Runoff Volume as a Function of Rainfall and Catchment Characteristics
The expected variability of runoff volume due to the uncertainties in spatial distribution of rainfall and catchment characteristics is quantified. A physically-based mathematical model...
Synthetic Calibration of a Rainfall-Runoff Model
A method for synthetically calibrating storm-mode parameters for the U.S. Geological Survey's Precipitation-Runoff Modeling System is described. Synthetic calibration is accomplished...
Guidance on the Selection and Use of Sediment Discharge Formulas
The purpose of this paper is to discuss the sediment function module of the computer program SAM. SAM is being developed as a product of the US Army Corps of Engineers Flood Control Channels...
Optimal Design of Highway Drainage Structures
Hydraulic design of a bridge or culvert using a risk-based approach is to choose among the alternatives the one associated with the least total expected cost. In this paper, the risk-based...
Study on Hydrologic Response Via Channel Network Geomorphology
A drainage basin consists of slopes and channels. Slopes are the main fields at which rainfall input is converted into discharge. Stream-channels are the main fields at which the discharge...
Uncertainty Estimates for Rainfall-Runoff Model
Almost all rainfall-runoff link-node models in use today involve the subdivision of the catchment into smaller areas, linked together by a system of channel links. These 'link-node'...
Operational Model Development for Salinity Control
The 800 km2 Breton Sound estuary and watershed in Louisiana is being modeled to characterize its salinity regime in terms of hydrometeorological...
An Investigation of Continuity Equation and Flood Routing
In this paper, a flood routing scheme, which gives consideration to the advantages of both the Muskingum method and the unit hydrograph method, is derived by using the continuity equation...
Conservation Properties of Flow Simulation Models
The fundamental equations of fluid mechanics and hydraulics posses certain integral properties which should be maintained by their discrete analogs. In this paper the conservation properties...
Kinematic Wave Based Hydrologic Models with Different Solution Methods
The hydrologic simulation models RUNOFF and HEC-1 are applied to a 3212-ha watershed in New Jersey, and performances of the two models in predicting historical stromwater hydrographs from...
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...
Paleoflood Hydrology and Design Decision for High-Risk Projects
Paleoflood hydrology is not merely one of several alternative methods for risk-based design. Rather, certain kinds of accurate data on the largest paleofloods of recent millennia provide...
A Regionalized Rainfall-Runoff Stochastic Model
The single area unit hydrograph model is used to develop a distribution model which accommodates the uncertainty in rainfall over the catchment. By categorizing the available rainfall...
