This paper describes techniques used in frequency analysis, time series model building, forecasting, up-dating, and mapping. Domain knowledge of experts is transferred into the system...
Proposal for Combining Expert Systems and Canal Design
Expert Systems can be combined with a computer aided design methodology to develop a cost effective canal system. The System should consider a feasible set of design alternatives to satisfy...
Flood Impact and Management of Levees in Tennessee
The construction of private levees is causing flooding and erosion problems along several tributary rivers in West Tennessee. The severity of these problems is recognized by the State...
Impact of Polders Upon Flood Stage of Atrai River
A mathematical model study, using System 11 model of the Danish Hydraulic Institute, is made to assess the impact of flood control polders upon flood level of Atrai River in Bangladesh....
Development of the Hydrology Criteria Manual for Harris County, Texas
The Harris County Flood Control District (HCFCD) was created in 1937 with the primary objectives of reducing potential damages from flooding in the Harris County area and of providing...
Modeling a Multiple Well Groundwater Supply System
The paper is concerned with the simulation of existing groundwater supply systems. This encompasses the delivery of the groundwater from the wells to the water treatment plant, including...
Pressure Relief Design Around Pumping Plants
Hydraulic transient protection for an irrigation pipeline pump station can include optimized operating procedures, or design of surge relief equipment such as surge relief valves, and...
The Water Erosion Prediction Project: Model Overview
A new generation of water erosion prediction technology is being developed by the USDA Water Erosion Prediction Project (WEPP). The WEPP models are a new erosion prediction technology...
Proper Use of Effective Flow Boundaries
The determination of the appropriate effective flow boundaries is an important factor in the hydraulic modeling of the flow regime of a stream. It is especially critical in areas with...
Locating and Sizing Air Release Valves on Irrigation Systems
This writing is directed to persons involved in irrigation systems and describes the usage of air release and vacuum valves. Principles described are applicable to many other piping systems,...
Parameter Identifiability in Conceptual Rainfall?Runoff Models
Computers have played a major role in the evolution of hydrologic rainfall-runoff models. Besides providing the computational power required for the simulation of the complex interacting...
TVA Weekly Scheduling Model Application Experience
Development of TVA's Weekly Scheduling Model was completed in 1980. Eight years of experience covering a wide variety of applications has now been accumulated. Since the basic...
Simulation Model for Economic Irrigation Project Planning and Design
The principle design parameters considered are: water supply configurations (quantity, source and storage); shapes and sizes of the area to be served; on-farm irrigation techniques; cropping...
A Tale of Two Subjects: Modern Physics and River Mechanics
The Einsteins, father and son, made some of the greatest contributions to physics and to river mechanics, respectively. The modern phases of these two subjects are of roughly equal age....
Advances in Computational Mobile-Bed Hydraulics
A new conceptual approach to one-dimensional mobile-bed simulation is briefly described, along with two demonstrative examples. The approach is based on fully coupled solution of the unsteady...
Derivation of a Stability Principle from the Shields Criterion
