Operational Stream Channel Monitoring in Real Time

Author(s): Hogan, Dan (BC Ministry of Forests)
Subject: Hydrology, Technology/GIS/Modeling/Remote Sensing
Series: Forest Investment Account (FIA) - Forest Science Program


The overall objective of our proposed research is to establish a stream channel monitoring system. This will involve (1) construction of a sediment routing model linking channel stability in reaches to upslope sediment sources, (2) calibration of the model through development of a monitoring program, and (3) regionalization of the monitoring system (calibrating the model to pre-existing regional databases). The Carnation Creek database will be used to calibrate the model, as it contains over 25 years of stream channel survey data at a spatial and temporal frequency intense enough to resolve the full range of natural responses. The results from this proposed research will resolve questions such as: 1. what is the spatial/temporal monitoring frequency required to resolve both background variability and response to disturbance? 2. how effective/sensitive is the monitoring system in identifying, tracking and accounting for cumulative or downstream effects?
