After successfully occupying the benthos of all the Laurentian Great Lakes and connecting channels, quagga mussels [Dreissena rostriformis bugensis (Andrusov, 1897)] have been colonizing the western United States at a much faster rate. Study findings and management experience in the Great Lakes will benefit the water resource managers in the western United States and help them be better prepare...
The irrigation and drainage network of Zarrinehroud with an area of 65,000 hectares is the most important network of Lake Urmia basin, with the direct link to the lake. With the current crisis in the lake, an assessment of the existing network's performance is essential in the Urmia Lake Rescue Program. The purpose of this study was, therefore, to evaluate the transmission, distribution, and ut...
Changes in sedimentary profiles and stratigraphic architecture over time lake basins are shown to be relevant markers of climate changes terrestrial palaeoenvironments. The the Priabonian (late Eocene)–early Rupelian (early Oligocene) Alès–Saint-Chaptes–Issirac saline system has been reconstructed from sedimentological, biostratigraphic magnetostratigraphic analysis outcrops well cores. As a fu...
Stormwater catch basins are commonly treated with larvicides by mosquito control agencies to reduce local populations of mosquito species capable of transmitting West Nile virus. Recent evidence suggests that extended-release larvicides formulated to last up to 180 days in catch basins may not be effective in some basins due to chronic flushing, rapid dissolution, or burying of treatment in sum...
Hydrological models are simplified representation of the real basin system, which helps to assess basin function in response to different inputs and better understanding of hydrological processes. The HEC-HMS model is one of the most important hydrological models for Flood estimating volumes and discharge in watersheds. In this research, the HEC-HMS hydrologic model was used to simulate the ...
Two end-members characterize a continuum of continental extensional tectonism: rift settings and highly extended terrains. These different styles result in and are recorded by different extensional basins. Intracontinental rifts (e.g. East Africa, Lake Baikal) usually occur in thermally equilibrated crust of normal thickness. Rift settings commonly display alkali to tholeiitic magmatism, steepl...
The study of peak-ring basins and other impact crater morphologies transitional between complex craters and multi-ring basins is important to our understanding of the mechanisms for basin formation on the terrestrial planets. Mercury has the largest population, and the largest population per area, of peak-ring basins and protobasins in the inner solar system and thus provides important data for...
In much of the northern Great Plains, saline and hypersaline lacustrine brines are the only surface waters present. As a group, the lakes of this region are unique: there is no other area in the world that can match the concentration and diversity of saline lake environments exhibited in the prairie region of Canada and northern United States. The immense number of individual salt lakes and sal...
We investigate viscoelastic impact basin relaxation on Pluto for a variety of thermal evolution scenarios encompassing both convective and conductive ice shells. Basins smaller than 200 km in diameter do not relax appreciably, while relaxation fractions can be up to ∼60% for large impact basins. The main control on basin relaxation is the amount of radiogenic heat produced in the rocky core; ou...
