Planning and Implementation for Sustainable Management of Negombo Lagoon, Sri Lanka
The author narrates how an organized, poor and relatively marginalized set of coastal communities in Sri Lanka have, by collaborating with state agencies and establishing informed dialogue,...
Modeling Beach Erosion and Shore Evolution
The objectives of this paper are to review some hydraulic modelling techniques for the evaluation of beach erosion and shoreline evolution due to wave and current action. Both numerical...
Shore Protection Design?A Necessary Evil
Since much shore protection exists and further shore protection will be considered necessary in the future, this paper addresses the need for better design methods to replace the present...
Designing the Framework for Coastal Mapping and Database Building in Support of a Coastal Zone Management Program: Nova Scotia, Canada
The Province of Nova Scotia has undertaken a program to manage its coastal zone. In support of this program it was recognized early in the process that comprehensive sets of data and information...
Coastal Processes and Management of the Mahanadi River Deltaic Complex, East Coast of India
The Mahanadi river deltaic complex in the tropical climatic setting on the east coast of India has been studied with respect to geomorphology, land use/cover, coastal processes and management....
Filtering and Prediction on Freeways Using Markov Models
A Markov compartment model of freeway traffic flow is presented and used to derive a Kalman Filter which tracks a freeway section's density, broken down by destination. The filter is then...
Field Implementation and Testing of a Machine Vision Based Incident Detection System
This paper contains test results of a video detection device installed in the field for over two years and the development and field deployment of an incident detection sysytems called...
Video Image Processing Application: Automatic Incident Detection on Freeways
This paper presents the results of tests carried out in the last 3 months of 1992 regarding the Automatic Incident Detection System elaborated in the INAVID project (DRIVE program). This...
Image Measurement Systems for Traffic Analysis?Specifications, Survey, and Limits
This presentation is concerned with systems for extraction of road traffic information from visual images. The extracted information ranges from macro-scale, cumulative traffic parameters...
Stochastic Generation of Daily Low Flows in Estuaries for Salinity Intrusion Studies
Stochastic data generation technique was used to provide a probabilistic approach to a salinity intrusion/low flow study of an estuary in West Malaysia. The Kemaman River on the east coast...
Stochastic Modeling for Drought Analysis
Periodic as well as annual stochastic streamflow models have been fitted to the highly variable flows measured at Krishnarajasagara (KRS) on river Cauvery (Southern India), which is monsoon-dependent...
Stochastic Modeling for Drought Analysis Using Thomas-Fiering Lognormal Three Parameter Model
Three variations of Thomas-Fiering log normal 3-parameter(TFLN3) model are fitted to the unregulated south-west monsoon-dependent monthly streamflows measured at Krishnarajasagara (KRS)...
Dynamic Perspective on the Capillary Barrier Effect at the Interface of an Upper Fine Layer with a Lower Coarse Layer
The theoretical principles behind the determination of infiltration rate into a coarse layer overlain by a tight layer are reviewed. As a descending unsaturated wetting front hits the...
Kinematic Mixing in Stratified Aquifers
The mixing process in heterogeneous aquifers is presented as the bending and stretching of material lines. A linear mixing efficiency is defined in terms of the mean values of a unit length...
Muskingum Basin Reservoir Pool Frequency Analysis
The purpose of the study was to develop a consistent and defendable elevation frequency analysis of pool elevations for sixteen reservoirs within the basin. A significant level of interest...
Modeling Two-Dimensional Subsurface Flow, Fate and Transport of Microbes and Chemicals
A two-dimensional model to simulate the subsurface flow, microbial growth-degradation, and transport and biodegradation of chemicals in groundwater environments (2DFATMIC) is developed....
A Unified Approach to Flood Frequency Analysis
Most stochastic hydrologic studies are based on statistical distributions that are pre-selected without giving consideration to the applicability of the distribution to a particular data...
Augmented TINFLOW: A Deterministic Runoff Model with a Stochastic Rainfall Input
Augmented TINFLOW consists of a deterministic runoff model based on a Triangulated Irregular Network (TIN) description of a watershed. The rainfall input is created by simulating convective...
In-Situ Bioremediation Using a Recirculation Well
An existing model (Semprini and McCarty, 1991; 1992) of in-situ bioremediation using methanotrophic bacteria for degradation of volatile organic compounds was modified to simulate use...
Real-Time Dynamic Flood Routing with NWS FLDWAV Model Using Kalman Filter Updating
Dynamic flood routing model based on the four-point implicit finite-difference solution of the complete one-dimensional Saint-Venant equations of unsteady flow are inherently deterministic....
