Abstract:
... Watershed morphological analysis is momentous for controlling floods risk, forethought and management of the watershed area, as well as it is foremost useful to perceive catchment hydrology. Remote sensing and geographic information system are used in recent times as a tool for watershed delineation and its planning. Many types of input parameters generally use for watershed delineation such as To ...

Abstract:
... Water level dynamics in catchment-scale rivers is an important factor for surface water studies. Manual measurement is highly accurate but inefficient. Using automatic water level sensors has disadvantages such as high cost and difficult maintenance. In this study, a water level recognition method based on digital image processing technology and CNN is proposed. For achieving batch segmentation of ...

Abstract:
... The use of integrated flood models represents an approach of growing interest in the literature, being the hydrological and hydrodynamic flood processes described entirely within the two-dimensional (2D) hydrodynamic unsteady flow equations. Due to its ability in simulating complex spatial–temporal dependence of both the hydrodynamic and hydrologic responses of a catchment to rainfall events, this ...

Abstract:
... Check dams are applied worldwide as an effective approach for soil conservation. Its effect on hydrology, however, has not been fully understood. As a critical step towards revealing the lumped effect of check dams at the regional scale, this study explored the modified flood hydrology induced by check dams in a representative highly erodible catchment in the Loess Plateau, China. A coupled hydrol ...

Abstract:
... Understanding the relationship between topography, hydrological processes, and runoff source areas is essential in engineering design, such as predicting floods and implementing effective watershed management practices. This relationship is not well defined in the highlands with a monsoon climate and needs further study. The objective of this study is to relate topographic position and hydrologica ...

Abstract:
... Wetlands strongly interact with groundwater and surface water, influencing catchment hydrology and altering water quality. Meanwhile, catchment-scale models are typically unable to simulate groundwater-wetland interactions despite the fact that quantifying groundwater-wetland interactions can assist in better identifying locations for wetlands restoration/creation. We modified an integrated ground ...

Abstract:
... Understanding and predicting bedload transport is an important element of watershed management. Yet, predictions of bedload remain uncertain by up to several order(s) of magnitude. In this contribution, we use a 5‐year continuous time series of streamflow and bedload transport monitoring in a 13.4‐km² snow‐dominated Alpine watershed in the Western Swiss Alps to investigate hydrological drivers of ...

Abstract:
... Acquiring high-quality rainfall data is very important for studying catchment hydrology. This data can be obtained by merging Satellite Rainfall Estimates (SREs) and gauge observations as highlighted by several researchers. However, the application of these merged rainfall products for hydrological modeling has rarely been explored in a complex topographic region like Melkakuntire catchment, Ethio ...

Abstract:
... The recent sprawl of urbanization in the Eastern U.S. perpetuated by population growth and economic success has caused landscapes to become vulnerable to degradation. As urban development encroaches on such landscapes, various anthropogenic stressors are introduced including air pollution, land conversion, and alterations in watershed hydrology. Across various disciplines, urban forests have been ...

Abstract:
... Soil hydraulic properties are often influenced by agricultural activities. Knowledge of such properties is needed to understand the effect of agricultural practices on the soil water regime and catchment hydrology. In the present study, we investigated the effects of three land use types including orchard field, OF (without plowing), annual cultivated field, ACF (with seasonal plowing), and perenn ...

Abstract:
... Land use/cover (LULC) and climate are significant environmental factors that influence watershed hydrology across the globe. The present study attempts to understand the consequences of existing changing patterns of climate and LULC on the hydrology of the Usri watershed. Different water balance components were simulated using a semi-distributed Soil and Water Assessment Tool (SWAT) model. Sixteen ...

Abstract:
... Context The Brigalow Belt bioregion of central Queensland has been extensively developed for agriculture since exploration by Leichhardt in 1844. About 4.5million hectares of vegetation dominated by brigalow (Acacia harpophylla) was cleared as part of the Land Development Fitzroy Basin Scheme, which commenced in 1962. When the Vegetation Management Act 1999 commenced, 93% of brigalow woodland had ...

Abstract:
... Land use and land cover (LULC) changes, climate variability and climate change (CC) contribute hydrological response in tropical catchments, but their individual and combined effects are not yet well known. To understand watershed hydrology, remote sensing was used for quantifying the change in land use for the years 1992 and 2015. Subsequently, the spatial distributed SWAT model was implemented t ...

Abstract:
... Hurricanes are one of the most significant threats to coastal plain forest ecosystems and urban communities of the southeastern U.S., but their implications for watershed hydrology are unclear. Hurricanes have the potential to alter water balances, causing extensive flooding, biogeochemical cycle disruption, and water quality degradation, saltwater intrusion, and increased nutrient sedimentation e ...

... This paired watershed study investigated the hydrologic impacts of low impact development (LID) stormwater control measures (SCMs) receiving runoff from a highly impervious, highly connected commercial parking area located in Reynoldsburg, Ohio, USA. The site was retrofitted with a bioretention cell and permeable pavement, treating 0.60 ha and 0.42 ha of the parking lot, respectively, following a ...

... The use of cosmogenically produced sulfur-35 (T₁/₂ = 87 days) and sodium-22 (T₁/₂ = 2.6 years) as intrinsic tracers can provide valuable information on catchment hydrology, flow paths, and subsurface storage. A new and straightforward method was created to determine the activities of both ³⁵S and ²²Na in various water sources by pumping large volumes (up to 1000 L) of water through cation- and ani ...

The article presents the experience in the application of a hydrological conceptual model HBV, including its standard version and modifications, to studying runoff-formation processes on small experimental catchments in the upper reaches of the Ussuri R. based on field observation data in the warm seasons from 2012 to 2019. It was shown, that, in many cases, whatever the structure of the model, th ...

Abstract:
... The assessment of climate change impacts on water resources and flood risk is typically underpinned by hydrological models calibrated and selected based on observed streamflow records. Yet, changes in climate are rarely accounted for when selecting hydrological models, which compromises their ability to robustly represent future changes in catchment hydrology. In this paper, we test a simple frame ...

Abstract:
... Natural water retention measures (NWRMs) belong to the broad range of nature-based solutions and are receiving increased attention for targeting environmental problems of river catchments as they effectively support the restoration of natural processes and cycles. Challenges involved in NWRMs planning include the development of tools able to project and diagnose the effects at different spatial sc ...

Abstract:
... Understanding the pace of erosion through space and time may provide insight into how tectonic and climatic processes conspire to drive landscape evolution. However, determining whether erosion rates in a given locality have varied with past climate change remains challenging, and the mechanisms invoked to explain variations in past erosion rates are not well understood. In this study, we evaluate ...
