Water resource experts and leads at CEC, Matt Gramza and Steve Casey, sat down with CivilGEO’s engineering director, Chris Maeder, to share how CivilGEO’s software products have helped CEC amp up its game and achieve new levels of productivity with river analysis and storm water modeling work.Matt Gramza described some inefficiencies the firm routinely ...
In 2017, civil engineer Joseph Skupien was interested in trying GeoHECRAS, CivilGEO’s innovative river modeling software. With a distinguished career as a hydraulic engineer spanning more than 40 years, Skupien was accustomed to using the US Army Corps HEC-2 software and later the HEC-RAS software, and building hydraulic models with ...
LiDAR is used to construct digital terrain maps (digital surface models, digital terrain models), assess the state of coastal vegetation, and assess the ecological state of estuaries. ...

Have you ever considered the factors that influence dissolved oxygen levels in rivers across the United States? Penn State found that temperature is the most important factor influencing oxygen levels in US rivers by using a deep learning model on data from several hundred water bodies. ...
Client: Conservation Authorities of the Moraine Coalition, 5 Shoreham Drive, Downsview, Ontario. Steve Holysh, Chief Hydrogeologist, 416-661-6600 ext. 5588 Key Personnel: E.J. Wexler, D. Kassenaar, A. Kodippili, John Ford. The Regional Municipality of Durham lies east of Toronto and encompasses an area of approximately 2,600 square kilometres. Population centres within the area include a number ...
Earthfx Incorporated developed a preliminary regional-scale groundwater model for the entire Grand River Conservation Authority area. The objective of the study was to better understand regional groundwater flow in the GRCA and evaluate the interaction between the river and the various aquifer systems in the basin. A key aspect of the study was ...
This study followed an earlier modelling analysis for route selection, also completed by Earthfx. The numerical model developed for the area surrounding the SEC encompassed the Rouge River and Duffins Creek watersheds. The model built on the geologic database and conceptual hydrostratigraphic model for the ...
He is working with Aquanty Inc. in Waterloo, Ont., the developers of 3-D flexible grid hydrological models for several watersheds in Canada. Bullock has a new project proposal to develop a model for the Red River area, a substantially different watershed than some of the others they’ve made. ...
Two 3-dimensional numerical groundwater flow models were constructed: a “sub-regional” model to simulate the long-term effects of dewatering on aquifer conditions and on local rivers and creeks. This model was used for the feasibility study for the mine and in support of the mine permitting process; and a near-pit ...
While the stream flow forecast models have traditionally relied on precipitation, snow pack and river flow data, new emerging models are starting to address the role soil moisture is having on streamflow. ...
Afterwards, an integrated ELM (I-ELM) was developed based on conceptual reservoir modeling to predict monthly river runoff where the model had the semi-distributed specifications of ELM. This model was capable of exploring spatial variation of rainfall–runoff process without requiring physical characteristics of sub-basins. ...
The daily model employs forecasts of the tributaries in its input structure in order to predict the daily flow in the main river in the next time steps. ...
The black-odor mechanism of Yitong River was analyzed based on survey and monitoring results. We found that organic matter is the main pollution source of Yitong River and its tributaries. A black-odor evaluation model that can describe the pollution of the Yitong River water system was developed, and this ...
We present an integrated three-dimensional (3D) spillway model where the realistic and complicated river terrain is implemented by the platform CATIA (Computer Aided Three Dimensional Interactive Application). This integrated 3D spillway model allows for complicated topographic and geomorphic conditions and describes the spatial distribution ...
City leaders across the Minnesota River Basin are protesting proposed phosphorus standards, which they contend will be too expensive and have little or no effect on water quality. ...
A comprehensive software package (xpswmm) for modeling stormwater, sanitary and river systems was selected as a tool to model the WIP, represent the complicated nature of the runoff patterns and to track suspended solids generated in rainfall events. ...

In the present work, a two-dimensional (2D) hydraulic model was used for the simulation of river flow and sediment transport in the downstream section of the Koiliaris River Basin in Crete, Greece, based on two different structured grids. Specifically, an important goal of the present study was the comparison of a curvilinear grid ...
A large number of fish-based indexes have been developed to monitor and manage river ecosystems. Biophysical and statistical models are being used to identify influential stream variables that correlate with macroinvertebrate indices. A probabilistic fuzzy hybrid model to assess river water quality is proposed. The method and ...
The urban agglomeration polders type of flood control pattern is a general flood control pattern in the eastern plain area and some of the secondary river basins in China. A HEC-HMS model of Qinhuai River basin based on the flood control pattern was established for simulating basin runoff, examining the impact of urban agglomeration polders ...
