SWMM-CAT allows users to evaluate climate change impacts on stormwater runoff volume and quality, and to explore how the application of various low-impact development (LID) options can be used to alter these hydrological parameters. SWMM provides a spatial and temporal analysis of runoff quality and quantity by dividing basins into multiple sub-catchment areas and analyzing runoff at different time steps. It covers a variety of different drivers that can cause runoff in urban areas, including rainfall, snowmelt, and groundwater percolation, among others, and also allows for mapping and modeling of different sub-catchment drainage system components, including pipes, channels, diversion structures, storage and treatment facilities, and natural channels. These components allow users to examine relationships between total rainfall, runoff, and various routing options at a sub-catchment scale to effectively plan and design stormwater and sewer systems.
WEPPCAT is a free, online erosion simulation tool that allows users to analyze potential stream sediment loading in response to various climate change and land management scenarios. WEPPCAT leverages the existing USDA Water Erosion Prediction Project (WEPP) Model, but has additional features that allow analysis of climate impacts and various land management practices on soil yield and loss. This tool allows for high user customization; users select their location (e.g., state, nearest climate station, soil type) and field characteristics (e.g., length, width, slope angle and shape, crop or management type), and can manipulate land management components to simulate adaptive management.
Read Hal Shepherd's Op-ed in the August 10, 2017 edition of the Homer News addressing the issue of whether the Alaska Energy Authority's proposal to divert water from the West Fork Upper Battle Creek drainage in order to supplement the power generating capacity for the Bradley Lake Hydroelectric Project near the Fox River Flats estuary on the east end of Kachemak Bay, would actually be good for fish.
What an inspiration to know that climate scientists are not discourage by the current, popularity of attacks on facts and science and are still coming out with great stuff. The latest is the Audubon Society's recently released "Ecological Atlas of the Bering, Chukchi, and Beaufort Seas" which shows how the natural world and human activities overlap in the rapidly changing Arctic marine ecosystems. The Atlas covers Physical and Biological Setting, Fishes, Birds, Mammals, Human Uses and more.
WASHINGTON — The average temperature in the United States has risen rapidly and drastically since 1980, and recent decades have been the warmest of the past 1,500 years, according to a sweeping federal climate change report awaiting approval by the Trump administration.
The Trump administration on Monday said the entirety of Alaska's petroleum reserve, including the half that had previously been unavailable for leasing to oil companies, is on the table for discussion as an area of future development.
The Bureau of Land Management said Monday it will take public comments to gauge interest in potentially holding lease sales for all of the 23 million-acre National Petroleum Reserve in Alaska, the nation's largest petroleum reserve.
Native American Tribes Reject Trump's Stance on Climate Change and Pledge to Uphold the Paris Agreement
A group of Native American tribes have said they will continue to uphold the Paris Climate Change Agreement despite Donald Trump's withdrawal from it earlier this year. Four Native American nations across three US states have joined together to “aggressively address climate change” after the federal government announced it would withdraw from the agreement, signed in December 2015.
A government scientist who studied dangerous climate change in the Arctic got an ironic reassignment at the Interior Department from the Trump administration: collecting checks from oil and gas companies. Joel Clement, the former director of the Interior Department Office of Policy Analysis, believes he was reassigned because he worked on climate change. Clement joins William Brangham to explain.
I am not a member of the deep state. I am not big government.
I am a scientist, a policy expert, a civil servant and a worried citizen. Reluctantly, as of today, I am also a whistleblower on an administration that chooses silence over science.
