This study examined the changes in rainfall-runoff characteristics in the year prior to and after intensive thinning of 50% in number in a steep headwater catchment, covered with 46-year-old Japanese cedar and cypress in western Japan. The magnitude of event peak flow, event quick flow, event water yield, and event response time did not change after thinning. Because 70% of rainfall events had ...

BACKGROUND Involuntary psychiatric care remains controversial. Geographic disparities in its use can challenge the appropriateness of the care provided when they do not result from different health needs of the population. These disparities should be reduced through dedicated health policies. However, their association with the supply of health and social care, which could be targeted by such p...

This study aims to clarify the contributions of pre-event water storm runoff using environmental tracers (dissolved inorganic ions and stable isotopes) in a tropical forested catchment Puchong, Selangor, Malaysia. We performed intensive sampling campaigns stream throughfall for two events July November 2018. The discharge showed low peak 0.13 mm/h event 1, with 18 mm total rainfall, whereas 2, ...

Bankfull discharge was identified in some 30 gravel-bed rivers representing in total c. 40 gauging stations. The catchment sizes vary from 4km2 to nearly 2700km2. Bankfull discharge value increases with basin size. In the case of gravel-bed rivers developed on an impermeable substratum, the following equation emerges: Qb=0·087 A 1·044. Bankfull discharge recurrence interval was determined by fi...

The measurement of phase resolved partial discharge requires a gigantic memory capacity to store all the waves of the PD test results. This limitation eventually hinders the testing. It is necessary to optimize on the aspect of memory storage capability to reduce the storage requirements. In light of foregoing, the partial discharge data retrieval techniques with sampling rate methods were used...

Ngwerere and Kanakatampa Streams are the main tributaries of Chongwe River. The stream originates from city Lusaka meanders through City Town for an approximate distance 41 km before joining into upper part Stream is a tributary It Area approximately 52 discharging middle River Catchment which sub-catchment Zambezi Basin drew attention researchers policymakers when started drying up in dry seas...

Abstract Evolutionary algorithms (EAs) are proficient in solving the controlled, nonlinear multimodal, non-convex problems that limit use of deterministic approaches. The competencies EA have been applied various environmental and water resources problems. In this study, storm management model (SWMM) was set up to authenticate capability for simulating catchment response upper Damodar River bas...
