Good Morning #Canada
OTD in 1972, construction begins on Canada’s largest single-site #Hydroelectric project at Churchill Falls, Labrador. To commemorate this minor historical event in our country's impressive record of hydroelectric technology and power generation, let's focus on one of the newest projects. The controversial Site C in British Columbia will begin filling its reservoir this summer in preparation for starting operations.

Geospatial Diffusion for Land Cover Imperviousness Change Forecasting
Land cover, both present and future, has a significant effect on several important Earth system processes. For example, impervious surfaces heat up and speed up surface water runoff and reduce groundwater infiltration, with concomitant effects on regional hydrology and flood risk. While regional Earth System models have increasing skill at forecasting hydrologic and atmospheric processes at high resolution in future climate scenarios, our ability to forecast land-use and land-cover change (LULC…

Detection and Classification of Internal Leakage in Hydraulic Cylinders
Hydraulic systems have been one of the most used technologies in many industries due to their reliance on incompressible fluids that facilitate energy and power transfer. Within such systems, hydraulic cylinders are prime devices that convert hydraulic energy into mechanical energy. Some of the genuine and very common problems related to hydraulic cylinders are leakages. Leakage in hydraulic systems can cause a drop in pressure, general inefficiency, and even complete failure of such systems. T…

Less than two years ago,
the administration of President Joe Biden announced what tribal leaders hailed as an unprecedented commitment to the Native tribes
whose ways of life had been devastated by federal dam-building along the Columbia River in the Pacific Northwest.
The deal, which took two years to negotiate, halted decades of lawsuits over the harm federal dams had caused to the salmon that had sustained those tribes culturally and economically for thousands of years. …

Trump Administration Abandons Deal With Northwest Tribes to Restore Salmon
The Trump administration canceled a deal, signed under President Joe Biden, that would have enabled the removal of four hydroelectric dams along the Columbia River that are considered harmful to salmon.

Salmon aren’t breaded and served in a bucket, so he doesn’t care.

Zwei Stunden lang Lego sortieren hat mir große Freude bereitet. Kategorien identifizieren und Prozesse optimieren mag mein autistisches Hirn. Wenn der chaotische Haufen vollständig wegsortiert ist, sprudelt es nur so in mir.
Ich habe die Kiste von meinen Eltern geholt, damit ich alleine und mit dem Kind bauen kann. Das Kind hat direkt Gefallen an den hydraulischen Elementen gefunden. Die habe ich früher auch geliebt. Ich bin gespannt, ob ich heute mehr aus dem programmierbaren Ding rau…

Bayesian Models for Joint Selection of Features and Auto-Regressive Lags: Theory and Applications in Environmental and Financial Forecasting
We develop a Bayesian framework for variable selection in linear regression with autocorrelated errors, accommodating lagged covariates and autoregressive structures. This setting occurs in time series applications where responses depend on contemporaneous or past explanatory variables and persistent stochastic shocks, including financial modeling, hydrological forecasting, and meteorological applications requiring temporal dependency capture. Our methodology uses hierarchical Bayesian models w…

A low-rank solver for the Stokes-Darcy model with random hydraulic conductivity and Beavers-Joseph condition
This paper proposes, analyzes, and demonstrates an efficient low-rank solver for the stochastic Stokes-Darcy interface model with a random hydraulic conductivity both in the porous media domain and on the interface. We consider three interface conditions with randomness, including the Beavers-Joseph interface condition with the random hydraulic conductivity, on the interface between the free flow and the porous media flow. Our solver employs a novel generalized low-rank approximation of the lar…
