This study aimed to assess the efficacy of a minimal intervention focusing on hypnotic discontinuation and cognitive-behavioral treatment (CBT) for insomnia. Fifty-three adult chronic users hypnotics were randomly assigned an 8-week taper program, used alone or combined with self-help CBT. Weekly use decreased in both conditions, from nearly nightly at baseline less than once week posttreatment. Nightly dosage (in lorazepam equivalent) 1.67 mg 0.12 mg. Participants who received CBT improved...
This paper presents the methodology and results of a vast study on climate change impacts hydrology for province Québec 2050 horizon. A ensemble was first built with simulations from World Climate Research Programme (WCRP)'s Coupled Model Intercomparison Project phase 3 (CMIP3) multi-model dataset, North American Regional Change Assessment Program (NARCCAP) Canadian (CRCM) operational runs. Direct outputs post-processed data were used as input to calibrated HSAMI hydrological model in order...
Abstract An assessment of interactions between groundwater and surface water was carried out by applying two different modeling approaches to a small‐scale study area in the municipality Havelock, Quebec. The first approach involved commonly used sequential procedure that consists determining daily recharge rate using quasi 2D infiltration model (HELP), applied next step as an imposed flux 3D finite‐element flow model. calibrated under steady‐state transient conditions against measured...
Abstract Different sets of calibrated model parameters can yield divergent hydrological simulations which in turn lead to different operational decisions or scientific conclusions. In order obtain reliable results, proper calibration is therefore fundamental. This article proposes a new approach for conceptual models based on the paradigm that process representation, along with reproduction observed streamflows, need be taken into account when assessing performance model. Several studies...
Abstract This study explores flow regulation controls on daily river discharge variations and trends into Hudson Bay from four highly regulated 17 moderately regulated/unregulated systems over 1960–2016. These 21 rivers contribute ~70% of the total annual riverine freshwater export to Bay, with accounting for 47% 53% discharge, respectively. Daily observed streamflow data Water Survey Canada, Manitoba Hydro, Ontario Power Generation, Hydro‐Québec are used. Decadal hydrographs mean...
Spatial distribution of macrozooplankton was studied during spring in Lake Geneva to evaluate the influence abiotic (water temperature and stability, nutrients) biotic (bacteria, chlorophyll a, fish biomass) factors on distribution. Mapping spatial analyses revealed that factors, as well crustacean abundances, were structured along a gradient great lake basin. Chlorophyll biomass, bacteria density, cyclopoid abundance, biomass showed more patchy or inshore-offshore patterns. Using canonical...
Significant progress has been made in the past years to improve quality of streamflow data and assess potential hydroacoustics. However, little effort monitoring techniques for under-ice streamflow. This paper presents a case study which index velocity method is used ice-affected with an acoustic Doppler meter (ADVM). The particularly interesting since it reliable during periods backwater effects, fully automated objective. In this particular study, rating was obtained five years, only two...
