The problem
We wanted to increase sleep and decrease anxiety in the hospital setting with a holistic approach. We wanted a solution that could be used in any hospital or patient-adjacent setting, was non-pharmacological, inclusive, and safe for patients of various ages and diagnoses. We were also noticing many veterans reporting they use white noise at home either passively (ceiling fans, A/C units, etc.), or actively via their phones or home devices.

SLEEP DISTURBANCES IN THE HOSPITAL
Hospitalized patients experience fragmented and poor quality sleep and are at risk for marked circadian rhythm disturbances. These changes become more pronounced with worsening severity of illness as well as in the immediate postoperative period. In some cases, sleep impairments persist well beyond the acute illness [3-6].

Poor sleep quality — Patients regularly report poor quality sleep during hospitalization across a range of inpatient settings [7-10]. Impaired sleep quality has been cited by patients as one of the main stressors during hospital admission [11,12] ...............................

Two Sides to North Vancouver's Eldon Park small playground, one safe, one needs a fence

"This small playground is located near Capilano Highlands, in Eldon Park, in a quiet residential area.  It is best for small children: it has a climbing dome, and a toddler sized play structure with sliding and climbing options.  There are two swings - one baby and one regular - at the playground, and another pair of the same on the other side of the sports field look for the red poles."

Cleveland Dam's Western abutment is set in rock whereas the Eastern 'abutment' is a valley

The construction of a US$25M seepage control blanket at the Cleveland dam in Canada is due to start in March 2001. The potential for seepage and instability of the east abutment of the dam was first recognized in 1954 when the concrete dam was built. The western abutment is set in rock, but on the eastern side the buried rock valley is infilled with silt, sand, gravel and glacial till. It is hoped that the seepage control project will make the dam safer.

"Cleveland dam is a 91m high concrete gravity structure set in a deep bedrock canyon. Full reservoir supply level is at el. 146m and the dam crest is at el. 149m. In 1992, the dam was upgraded to pass the Probable Maximum Flood (PMF) and to withstand the Maximum Design Earthquake (MCE) event.

The dam impounds a reservoir extending 4.5km to the north where the Upper Capilano river flows into the reservoir. Typically 0.5km wide, the reservoir surface area is 2.3km2 at full reservoir level. Flow is controlled at the dam by a radial gate spillway, two mid-level intakes and outlets, and two low-level outlets."

 

"The dam is constructed in a bedrock canyon on the west side of the valley. Immediately east of the canyon is a wide, deep buried valley that extends about 2km (eastward from the dam to the base of Grouse Mountain. The buried valley extends to below sea level and is infilled with a complex stratification of silt, sand, gravel and glacial till. The west canyon bedrock is hard, moderately jointed granodiorite and quartz diorite with numerous inclusions of older sedimentary and volcanic rocks."

 Metro Vancouver utilising hydro potential at non-powered dams 

 
05 December, 2012
Metro Vancouver in Canada is proposing to generate electricity from its dams during rain drenched months of the year. The supply of high quality drinking water will remain the first priority of a new water use plan for the Capilano and Seymour Watersheds, which includes the Cleveland dam. Built in 1954 to create Capilano Lake for water storage, the dam currently does not capture energy from spilled water.

Seismic upgrade of Seymour Falls dam

 
23 May, 2006
The Seymour Falls dam is a key element in Canada’s Greater Vancouver Water District’s (GVWD) network of three watersheds. The 45-year-old composite earthfill embankment and concrete slab and buttress dam was found to not meet current seismic design standards, so upgrades to meet the requirements of the Maximum Credible Earthquake (MCE) are necessary. Part one of our two part report describes the structure and looks at how the safety problem was identified and analysed through site investigation and liquefaction assessment
