Prediction of scour depth at culvert outlets using neural networks
Prediction scour depth culvert outlets neural networks
2009/12/4
Scour at culvert outlets is a phenomenon encountered world-wide. Research into the problem has mainly been of an experimental nature, with equations being derived for particular circumstances. These t...
A method for systematically analysing text is outlined for use in the acquisition of specialist knowledge. Such knowledge can typically be engineered in the knowledge bases of hydroinformatic systems....
Investigation of a parameter estimation method for contaminant transport in aquifers
Investigation parameter estimation method contaminant transport aquifers
2009/12/4
Real world groundwater aquifers are heterogeneous and system variables are not uniformly distributed across the aquifer. Therefore, in the modelling of the contaminant transport, we need to consider t...
Stamped features:creation of engineered structures in conceptual models
Stamped features creation engineered structures conceptual models
2009/12/4
Applying numerical modelling techniques to surface water bodies often requires the addition of man-made structures such as embankments or dredged shipping lanes to the natural bathymetric conditions. ...
Evaluation of an ASM1 model calibration procedure on a municipal–industrial wastewater treatment plant
ASM1 model calibration procedure municipal–industrial wastewater treatment plant
2009/12/4
The purpose of the calibrated model determines how to approach a model calibration, e.g. which information is needed and to which level of detail the model should be calibrated. A systematic model cal...
An optimization approach to wastewater systems planning at regional level
optimization approach wastewater systems regional level
2009/12/4
A regional wastewater system planning problem consists of finding the minimum-cost configuration for the system needed to drain the wastewater produced at the communities located within a region, whil...
Conceptual user interface for the land management system
Conceptual user interface land management system
2009/12/4
This paper explores the conceptual user interface requirements of the Land Management System (LMS), a next-generation system designed to support the development of location-specific landscape/watershe...
Evolutionary algorithms for multiobjective evaluation of watershed management decisions
Evolutionary algorithms multiobjective evaluation watershed management decisions
2009/12/4
The comprehensive and systematic management of watersheds is essential for reducing the adverse environmental impacts arising from anthropogenically caused erosion and subsequent sedimentation. This p...
Design and development of a planning support system for policy formulation in water resources rehabilitation:the case of Alcázar De San Juan District in Aquifer 23,La Mancha,Spain
planning support system policy formulation water resources rehabilitation
2009/12/4
To support policy formulation for rehabilitation of the natural environment in the Western Mancha region in Spain, a planning support system was developed and applied. The system is based on a framewo...
Multicriteria analysis for choosing wastewater sewerage solutions
Multicriteria analysis wastewater sewerage solutions
2009/12/4
Today, more and more French communities have a critical point of view concerning the performance of their wastewater sewerage systems. The main reason is linked to the methodology of the studies in th...
Pollution of underground water-a computational case study using a transport model
Pollution of underground water computational case study transport model
2009/12/4
Damage of the waterproofing system in a waste material depository or sewage sludge composting plant and the penetration of pollutants into the soil and groundwater may cause an environmental mishap. A...
Sensitivity of urban drainage wash-off models:compatibility analysis of HydroWorks QM and MouseTrap using CDF relationships
urban drainage wash-off models compatibility analysis HydroWorks QM MouseTrap CDF relationships
2009/12/4
One of the key aspects in urban drainage (water quality) modelling is the accurate simulation of the input into such models. The modelling of surface sediment build-up, erosion and wash-off is discuss...
Open Source, in which the source code to software is freely shared and improved upon, has recently risen to prominence as an alternative to the more usual closed approach to software development. A nu...
随着全球变暖和冰川退缩加剧，冰川补给湖的水文状况发生了明显变化。对于冰川融水补给的过水湖泊来讲，获得湖泊的水位、出入湖流量，并将之与上游冰川融水情况进行对比，是深入了解冰川—湖泊变化关系和气候变化影响的关键。
