Citizen Science: Here’s Your Chance to Make a Difference by Mike Kelly
What if you could participate in a North America-wide effort to improve weather forecasting, drought mapping, flood alerts, and our understanding of and capacity to respond to an ever-changing climate? Would you? Of course you would. Well, here’s the opportunity.

Earth Day Resolutions 2015
For regular readers of this blog you may be familiar with the concept of “Earth Day Resolutions”. But for those who are new, or have forgotten, here is a quick summary:
Proposal: We use #EarthDay as a day to set resolutions about being more green friendly year-round.— Victoria Pleavin (@pleavin) April 22, 2013
Deltares looks at Flood Mitigation Proposals for High River
Today we’re moving out of the Elbow Basin and into the Highwood with a review of the flood mitigation proposals for High River. The Government of Alberta released a new report by Deltares which reviews the engineering study by AECOM and the Flood Management Master Plan by WorleyParsons.
The report makes some very direct recommendations on what should and should not be done next in the Highwood basin.
First, we recommend to not implementing the dry dams or southern diversion' schemes as studied by AECOM since they cannot be justified considering the societal costs and benefits of these measures. Secondly, we recommend being reluctant with regard to deliberately drawing more discharge into the little Bow since this may be considered morphologically unsustainable and not robust in view of uncertainty about design discharges. Instead we advise to try to further enhance the discharge capacity of the Highwood River through the town of High River itself by at least removing obstacles and perhaps reshaping (and maintaining) the.channel and floodplain morphology.

Flood Insurance and Extreme Weather
Over the past few months, WaterPortal readers have raised concerns about reduced insurance coverage and increased rates related to flooding. We felt this presented the opportunity to revisit the impacts of flooding on insurance and take a look at broader climate change issues that could impact insurance coverage in the future.
Low Impact Development and Flooding: A drop in the bucket? by Leta van Duin
Conventional stormwater management relies on large-scale facilities such as dry ponds, wet ponds, constructed and natural wetlands to detain flows from large storm events.
