Connecting watershed and land use planning in Manitoba: exploring the potential of collaboration as a form of integration

Beukens, Robin 28 January 2013 (has links)
Watershed planning and land use development planning are two different planning processes dealing with many of the same water and land resources. Watershed planning is conducted on watershed boundaries; land use development plans focus on municipal or planning district boundaries. It is important that these plans are properly integrated so they are mutually supportive of one another. This study focuses on Manitoba, where land and water issues include potential floods and droughts, poor water quality in major lakes, and the need to protect drinking water for human use. The severity of these issues could increase in the future as Manitoba is projected to experience climate change that will further impact water and land resources in the province. The research explores different modes of integration, finding that collaboration is valuable in some circumstances in terms of maximizing collective resources, but that it is important to build upon strong cooperation and coordination. Results indicate that land use planners have a role to play in watershed management, using both technical and soft skills to protect watershed health through land use planning tools and plans. Watershed management planning and land use planning integration in other Canadian provinces is explored. The study concludes with a conceptual framework for integrating watershed and land use plans, as well as recommendations for improving integration in Manitoba, including: ongoing public education, pooling existing resources, more collaboration between watershed and land use planners, consideration of future water-related land use regulatory authority for watershed-based organizations, establishing clear responsibility for ensuring integration, continued learning by doing, creating a guiding framework for integrating watershed plans and land use plans, and using an adaptive management approach in both planning processes.

Delineating debris-flow hazards on alluvial fans in the Coromandel and Kaimai regions, New Zealand, using GIS.

Welsh, Andrew James January 2007 (has links)
Debris-flows pose serious hazards to communities in mountainous regions of the world and are often responsible for loss of life and damages to infrastructure. Characterised by high flow velocity, large impact forces and long runout, debris-flows have potential discharges several times greater than clear water flood discharges and possess much greater erosive and destructive potential. In combination with poor temporal predictability, they present a significant hazard to settlements, transport routes and other infrastructure located at the drainage points (fan-heads) of watersheds. Thus, it is important that areas vulnerable to debris-flows are identified in order to aid decisions on appropriate land-uses for alluvial fans. This research has developed and tested a new GIS-based procedure for identifying areas prone to debris-flow hazards in the Coromandel/Kaimai region, North Island, New Zealand. The procedure was developed using ESRI Arc View software, utilising the NZ 25 x 25 m DEM as the primary input. When run, it enabled watersheds and their associated morphometric parameters to be derived for selected streams in the study area. Two specific parameters, Melton ratio (R) and watershed length were then correlated against field evidence for debris-flows, debris-floods and fluvial processes at stream watershed locations in the study area. Overall, strong relationships were observed to exist between the evidence observed for these phenomena and the parameters, thus confirming the utility of the GIS procedure for the preliminary identification of hydrogeomorphic hazards such as debris-flow in the Coromandel/Kaimai region study area. In consideration of the results, the procedure could prove a useful tool for regional councils and CDEM groups in regional debris-flow hazard assessment for the identification of existing developments at risk of debris-flow disaster. Furthermore, the procedure could be used to provide justification for subsequent, more intensive local investigations to fully quantify the risk to people and property at stream fan and watershed locations in such areas.
