Many studies have been conducted on the characteristics of hydraulic jumps over horizontal basins. On sloping basins, however, few such studies have been performed so that the issue requires more investigation. A significant number of studies has also been conducted on basins with positive slopes but comparatively few have been carried out on basins with negative slopes. This study was carried ...
abstract: the aim of this study is analysis of drainage basins neotectonic in the north slope of bozqoosh mountains by geomorphological methods. to attain this aim, it used of field observation, areal photographs and five geomorphic indexes in 20 basins of the north slope of bozqoosh mountains. indexes were calculated by topography maps (1: 50000), geological maps (1: 100000) and areal photogr...
Effectiveness in controlling mosquitoes in storm water catch basins in the North Shore Mosquito Abatement District (northeastern Cook County, Illinois) was determined for 3 formulations of methoprene-based larvicides (Altosid XR 150-day Briquets, Altosid 30-day Pellets, Altosid 30-day Granules) in 2017 using a pass/fail evaluation criterion, in which emergence of a single adult from pupae colle...
Tectonic setting exerts fi rst-order control on basin formation as refl ected in basin subsidence history. While our approach ignores the effects of fl exural loading and eustatic sea-level change, consistency of backstripped subsidence histories (i.e., with local loading effects of sediment removed) suggests consistent tectonic driving mechanisms in each tectonic setting, with the possible exc...
This study analyses for the first time break in stilling detected by previous research around 2010, with focus Sweden using homogenized near-surface mean and gust wind speed observations 1997–2019. During recent past two decades, both magnitude frequency (exceeding 90th percentile) underwent nonlinear changes, driven dominant winter variability. In particular, consistent studies, significant (p...
the control of hydraulic jump through thin-crested sills in a trapezoidal channel was studied theoretically as well as experimentally. the experiments were conducted in a specially designed stilling basin for 1:1 side slope. the results show that for a given side slope, end sill increases the stability of the jump within the stilling basin. it also causes a 13-15 percent reduction in the length...
We present data on the efficacy of Mesocyclops longisetus as a biocontrol agent in controlling Aedes aegypti larvae in catch basins in Cali, Colombia. Additionally, we determined some of the features that facilitated the establishment of the copepods in catch basins. Between June 1999 and February 2000, 201 catch basins were treated with an average of 500 adult copepods. The copepods had establ...
The interior of British Columbia contains a number of fault bounded Tertiary basins that contain coal (Figure 1). This paper brings together existing data that aids in assessing the coalbed methane (CBM) potential of the basins and presents new data on some of the basins. The CBM potential of the basins ranges from up to 1 tcf at Hat Creek to a few bcf at Coal River. In all cases the resources ...
