This paper describes long-term hydrologic response within a rapidly developing watershed in the western suburbs of Washington, DC, within the Chesapeake Bay drainage basin. Data consist of up to 24 years of observed rainfall, basin discharge, and land use/land cover (LULC) from four headwater basins of the Occoquan River in northern Virginia. Basin outlets are monitored for storm and nonstorm f...

The distributions and abundances of gastropods collected in sediment grab samples in 1978 and 1979 in the southern nearshore zone of the central basin of Lake Erie were compared with earlier gastropod records from throughout the lake. Since the 1920s, 34 species in eight families have been reported for the lake proper. Sixteen species have been reported only once, 13 of them in three reports pr...

Interrelationships, origin and phylogenetic affinities of brown trout Salmo trutta populations from the southern Caspian Sea basin, Orumieh and Namak Lake basins in Iran were analysed from complete mtDNA control region sequences, 12 microsatellite loci and morphological characters. Among 129 specimens from six populations, seven haplotypes were observed. Based on mtDNA haplotype data, the Orumi...

We analyzed a varved sequence of sediment from a 350-m depth in the north basin of Lake Malawi, East Africa, for the size distribution of the sortable silt fraction (10–64 mm). Mean size of the sortable silt (SS) varies measurably in sediments spanning the past 650 yr and covaries with the mass accumulation rate of terrigenous silt and clay (TMAR) over much of the interval. Most of the silt and...

Hydrological similarity-based parameter regionalization is the dominant method used for runoff prediction in ungauged basin. However, application of this approach depends on assessing hydrological similarity between basins. This study data runoff, climate, and underlying surface Hulan River Basin Poyang Lake to construct a novel physical index (HSI). The was compare efficiency transfer paramete...

Expansive playa-lake systems situated in high-altitude piggyback basins are important and conspicuous components of both modern and ancient cordilleran orogenic systems. Extant playa lakes provide vital habitat for numerous endemic species, whereas sediments from these deposystems may record signals of climate change or develop natural resources over geological time. Laguna de los Pozuelos (Nor...
