3D Layer-Integrated Modelling of Morphodynamic Processes Near River Regulated Structures

An integrated modelling framework for regulated river systems

Management of regulated water systems has become increasingly complex due to rapid socio-economic growth and environmental changes in river basins over recent decades. This paper introduces the Source Integrated Modelling System (IMS), and describes the individual modelling components and how they are integrated within it. It also describes the methods employed for tracking and assessment of un...

Modelling hyporheic processes for regulated rivers

Understanding the effects of major hydrogeological controls on hyporheic exchange and bank storage is essential for river water management, groundwater abstraction, restoration and ecosystem sustainability. Analytical models cannot adequately represent complex settings with, for example, transient boundary conditions, varying geom-5 etry of surface water–groundwater interface, unsaturated and o...

Morphodynamic Changes of Bhagirathi River at Murshidabad District Using Geoinformatics

The channel of Bhagirathi River is the branches off from the Ganga at Nurpur (lower course of the Ganga). Bhagirathi River is one of the main rivers in Murshidabad district. Analyzing the image of the Bhagirathi River in Murshidabad district through the year 1970, 1977, 1990, 2000 and 2006, it is found that significant changed has been occurred in souththern part of the river and less change is...

Integrated 3D Modelling within a GIS

This paper describes the architecture of a truly integrated D GIS The system has two main components an extensible database Postgres and an extensible geographic front end GEO The database is extended with D geometric data types functions and a D access method The implementation of the D visualization is based on the graphics standard PEX The resulting system is again extensible and can be used...
