The structuring role of artificial structure on fish assemblages in a.
Such particular characteristics play an important role in water and energy balance, and affect the dynamics of actual evapotranspiration, infiltration, and runoff in KMR. As pointed out by Kiraly [10], the hydrological behavior of the karst systems shows a duality in its dynamics: duality of infiltration and recharge processes, duality of the. The U.S. Department of Energy's Office of Scientific and Technical Information. Calibrating spatially distributed hydrological models in ungauged mountain basins is complicated due to the paucity of information and the uncertainty in representing the physical characteristics of a drainage area. In this study, an innovative method is proposed that incorporates the Budyko framework and water balance equation derived water yield (WYLD) in the calibration of the Soil and.

Rudiger Gens; Rudiger Gens Alaska Satellite Facility, Geophysical Institute, University of Alaska-Fairbanks, Fairbanks, AK 99775. Over a 5-year period (2008-2012), meteorological data consisting of maximum and minimum air temperature, relative humidity, wind speed, and sunshine duration were collected from four weather stations: BaiSe, DuAn, HeChi, and RongAn. Basin is a dynamic and very complex system, which has mainly two types of characteristics (Usul, 2001): Geomorphologic characteristics of the basin are; area, shape, and slope. These characteristics can be assumed to be constant, since they change in a very long time. Hydrologic characteristics are; stream shape, infiltration capacity, soil.
Hydrological basin: characteristics, types, flora, fauna, examples.
By the harsh terrain conditions and complicated geological and hydrological conditions along the route. On the one hand, the technical standards are low, so that local sections cannot meet the technical standards for Class-III highways, full of detours and steep slopes on the narrow road, with imperfect security facilities and many potential safety. Precipitation is one of the most important factors in the hydrological process and is the main driver of variability in the water balance over space and time. fig. 3 shows the temporal changes in the reconstructed mean precipitation, water discharge, and sediment load in the pearl river basin at the third level timescales using the db3 wavelet.

Abstract Mountaintop mining (MTM) affects chemical, physical, and hydrological properties of receiving streams, but the long-term consequences for fish-assemblage structure and function are poorly understood. We sampled stream fish assemblages using electrofishing techniques in MTM exposure sites and reference sites within the Guyandotte River basin, USA, during 2010-2011. We calculated. Artificial structures are constructed to mimic some of the characteristics of a natural habitat in aquatic environments with multiple purposes such as attracting and concentrating fish (Bolding et al., 2004), enhancing fish population density (Wills et al., 2004), and offering shelter for juvenile fish (Höjesjö et al., 2015). Abstract. The "Digital Earth" (DE) metaphor is very useful for both end users and hydrological modelers (i.e., the coders). In this opinion paper, we analyze different categories of models with the view of making them part of Digital eARth Twin Hydrology systems (DARTHs). We stress the idea that DARTHs are not models, rather they are an appropriate infrastructure that hosts (certain types.
HESS - Quantifying multi-year hydrological memory with Catchment.
2.1. The Hemlock Woolly Adelgid. Adelges tsugae (henceforth, the "adelgid") is a small (≈1.5 mm) insect that was first detected in the early 1950s in eastern North America near Richmond, Virginia; the detected lineage originated in Japan in [34,35].In the subsequent six decades, the adelgid has established populations in 19 states—from Georgia to southern Maine and west into Michigan. Indeed, the natural hydrological characteristics of Poyang Lake Basin were also changed by dams. There were 25 large reservoirs and 238 medium-sized reservoirs in this basin. In this study, the beta diversity clearly showed that the increase in the composition dissimilarity of the fish fauna may be correlated with dam construction, particularly. The upper Berg River plays a critical role in contributing to both base flows and small floods in the lower river, contributing on average 72% of the flood peak in the lower reaches, for floods.
Dynamics of dissolved organic matter (DOM) in a typical inland lake of.
Among the many hydrological characteristics/signatures of a watershed, the most important ones are: 1. Flood frequency curve 2. Low flow recession behavior 3. Flow duration curve (flow quantiles,. Baise city is one of the largest producers of mangoes, with this agricultural industry located in the karst region of Southwest China. However, calcium-rich and alkaline soils, severe soil fragmentation, and poor water and fertilizer retention capacity contribute to low mango yields and are key issues that limit the development of the mango. Sep 17, 2018 · The research findings are as follows: (1) the main hydrological disasters in Urumqi are caused by floods, snow, and droughts, among which floods have the greatest risk, while the risk of droughts is minimal.
Hydrological characteristics and water resources management.
Based on hydrological date of Haihe basin representative hydrological station from 1956 to 2008 years,applied the method of hydrologic statistics and the variation distribution laws are analyzed such as runoff,sediment and storm flood,which can provides the adequate basis for exploiting its resources reasonably in Haihe river basin.
Correlation between hydrological drought, climatic factors, reservoir.
For the scheme one, according to the designed results of baise-laokou interval flood, intervals of frequencies of 10, 5, 2, 1, 0.5, 0.2, 0.1 and 0.05% are respectively selected to design the flood, made addition and random combination with flood arrival regulated for 100 thousands times and evolved to the downriver in the baise reservoir by. 140Chapter 5 −Hydrological Drought Characteristics below 0°C (Hisdal et al., 2001). In very cold climates, there might be snow melt during the whole summer season and hence only ‘winter drought’ exists and studies of ‘summer drought’ are not relevant. General drought definitions have already been presented in Section 1.2.

A 100 m long salt core (SQM #2005) from the Salar de Atacama, northern Chile (23°S, 68°W), a dry lake bed, contains a 106 kyr paleoclimate record of hydrologic balances on the western slopes of..
Using the wavelet transform to detect temporal variations in.
Trends and variability of hydrological variables can reflect the redistribution of seasonal patterns that can be caused by both climatic and anthropic factors. In this paper, China's East River,. An intermittent stream in the WOTUS rule means "…surface water flowing continuously during certain times of the year and more than in direct response to precipitation." This term is very tricky and may mean you have jurisdiction by EPA and/or by the Corps of Engineers or you may not.
Characteristics of water – LORECENTRAL.
Distributed hydrological simulation in karst regions has always been a challenging task because of their unique hydrogeological characteristics. The karst mountain region of southwest China (KMRSC), one of the largest continuous karst areas in the world, contributes to about 54 percent of water supply in the basins. In spite of its importance, we have a poor understanding of the evolution laws. 80% of the temporal variability for 85 hydrological gauges across China. The mean relative errors were within 20% for 66% of the studied stations and within 30% for 86% of the stations. The Nash-Sutcliffe coefficients indicated that the quantity pattern. The characteristic hydrological feature of all IRES is intermittence (Chapter 1), often followed by drying of part or all of the channel (Fig. 2.3.3).Rewetting usually coincides with the onset of sustained flow although in some IRES, there may be several "false starts" where surface water is present or pools fill and then dry for several weeks or even months before streamflow begins in.
