A GIS-supported 3D approach for flood risk assessment of the Qu'Appelle River, Southern Saskatchewan
This research introduces a hybrid approach for flood risk assessment through GIS. The developed approach is based on the integration of hydraulic simulation and GIS analysis, which allows spatial-based visualisation and prediction of flood disaster. In particular, the Hydraulic Engineering Center River Analysis System (HEC-RAS) model is employed to simulate multi-scenario flood cases within a ...

Evolution of an integrated 1D/2D modeling package for urban drainage - Case Study
Introduction: Recent flooding events in North America have revealed deficiencies in existing stormwater infrastructure and management practices. The development of effective and efficient designs requires a comprehensive understanding of flooding in urban areas and complex open channel and overland flow systems. Traditional one dimensional (1D) models are used to simulate flow in river channels ...

Rapid Groundwater Exploration - Case Study
A Vehicle-Mounted Solution Using CrossOver CO730 Customer’s task The Swedish Geological Survey (SGU) has been engaged in groundwater exploration projects to investigate Sweden’s many glacial river deposits. The deposits are spread across the country and are the most significant groundwater resources for drinking water supplies in Sweden. SGU wanted a GPR solution to deploy rapidly to ...

WISPR Accuracy Study - RESEPI M2X vs. XT-32
Introduction What is a LiDAR Payload? LiDAR stands for Light Detection and Ranging and has become an increasingly prevalent technology over the past decade. NASA and meteorologists have used LiDAR, now embedded within cell phones with the release of the iPhone 12 Pro. LiDAR is commonly used in surveying, mapping, and inspection applications where it can provide very detailed and accurate ...

Assessing land use impacts on flood processes in complex terrain by using GIS and modeling approach
A distributed hydrologic modeling and GIS approach is applied for the assessment of land use impact in the Steinsel sub-basin, Alzette, Grand-Duchy of Luxembourg. The assessment focuses on the runoff contributions from different land use classes and the potential impact of land use changes on runoff generation. The results show that the direct runoff from urban areas is dominant for a flood event ...
