surface water hydrology Articles

  • Eco-Hydrology

    The Habitats Directive and the Environment Agency’s Restoring Sustainable Abstraction programme (RSAp) have focused attention on a large number of wetland sites across the country. Some of these are large, high profile sites that have been subject to many detailed studies in the past. However, many sites have had little work carried out on them and the behaviour of their hydrological ...

  • Effects of hydrology and field management on phosphorus transport in surface runoff

    Received for publication December 5, 2008. Phosphorus (P) losses from agricultural landscapes arise from the interaction of hydrologic, edaphic, and management factors, complicated by their spatial and temporal variability. We monitored sites along two agricultural hillslopes to assess the effects of field management and hydrology on P transfers in surface runoff at different landscape positions. ...

  • Surface Runoff

    Surface runoff is the water flow that occurs when soil is infiltrated to full capacity and excess water from rain, snowmelt, or other sources flows over the land. This is a major component of the hydrologic ...

  • Data Requirements for Ground Water, Surface Water, and Leachate

    It is common for ground water to be contaminated with the water soluble substances found in overlying soils. Many of the required data elements are similar, e.g., pH, TOC, BOD, COD, oil and grease, contaminant identification and quantification, and soil and aquifer characterization. Additional water quality monitoring data elements include hardness, ammonia, total dissolved solids, and metals ...

  • Hydrological investigations and water resources management for wildlife sanctuary in central India

    The important hydrological issues in Nauradehi Wildlife Sanctuary (NWLS) are development of water resources, development of flora and fauna, trouble–free water availability for wildlife and retention of soil moisture for maximum forest growth. In the present study, the surface and groundwater resources of the sanctuary were estimated using water balance method. The results show that the sanctuary ...

  • Groundwater, flooding and hydrological functioning in the Findhorn floodplain, Scotland

    A large floodplain of the River Findhorn, northeast Scotland, was investigated using hydrogeological and hydrochemical methods (including residence time indicators) to characterise groundwater/surface-water coupling and groundwater flooding. The study demonstrated widespread stratification within the floodplain: shallow (<8 mbgl) deposits are highly permeable (100 m/d); deeper deposits ...

  • Green roof hydrologic performance and modeling: a review

    Green roofs reduce runoff from impervious surfaces in urban development. This paper reviews the technical literature on green roof hydrology. Laboratory experiments and field measurements have shown that green roofs can reduce stormwater runoff volume by 30 to 86%, reduce peak flow rate by 22 to 93% and delay the peak flow by 0 to 30 min and thereby decrease pollution, flooding and ...

  • Surface water Sulfate dynamics in the northern Florida everglades

    Received for publication August 24, 2007. Sulfate contamination has been identified as a serious environmental issue in the Everglades ecosystem. However, it has received less attention compared to P enrichment. Sulfate enters the Arthur R. Marshall Loxahatchee National Wildlife Refuge (Refuge), a remnant of the historic Everglades, in pumped stormwater discharges with a mean concentration of ...

  • Modelling the hydrologic effects of land-use and climate changes

    Climate and land use affect water quantity and quality; however, the complex relations of climate and land use regarding flow and instream nutrient levels have yet to be elucidated. This study aims to assess the hydrologic effects of different land-use and climatic regimes in the Lower Great Miami River Basin. The modelling results from BASINS showed that, as expected, agricultural lands and the ...

  • Long-term changes in hydrological regime of the lakes in Latvia

    Changes in the hydrological regime of the lakes of Latvia depend on natural and anthropogenic causes. This publication summarises the results of the research on the long-term changes in the water level, thermal and ice regimes in the seven largest lakes of Latvia: Liepājas, Usma, Ķīšezers, Burtnieks, Rāzna, Sventes and Lielais Ludzas, and their regional ...

  • Modelling the interaction of surface and subsurface water flow by linking TOPMODEL and MODFLOW

    A coupled ground water–surface water model was used to quantify the hydrological processes in a lowland watershed. The model was constructed by coupling TOPMODEL and MODFLOW without writing new code for the integrated model. Meteorological, land use and soil type data for the Tenmile watershed, USA, were used to run TOPMODEL, which partitions precipitation into evapotranspiration, runoff and ...

  • Uncertainty Analysis of Mound Monitoring for Recharged Water from Surface Spreading Basins

    This study has conceptually reviewed issues related to implementation of a groundwater mound monitoring well (GMMW) for monitoring recharged water from a surface spreading basin with emphasis on uncertain hydrogeological conditions. For this, we selected a recharge site in the City of Mesa, Arizona, that is characterized with near surface clay lenses of low permeability. A geostatistical ...

  • Quantitative assessment of the impacts of irrigation on surface water fluxes in the Tarim River, China

    Irrigation is a significant human activity that affects surface water fluxes in the Tarim River Basin. To quantitatively assess the irrigation impact of this activity on surface water fluxes in the Tarim River, a land surface hydrologic model was coupled with a modified irrigation scheme and a reservoir module and applied to simulate these fluxes. Modeling results indicate that the combined ...

  • Forest clearing, water loss, and land surface heating as development costs

    This paper documents the effects of development in Kenya and its subsequent influence on surface temperatures. The assumption is that deforestation leads to a decrease in evapotranspiration, and causes an observed temperature increase. The study was realised in the Mau Forest of Central Kenya, where extensive deforestation over the past 20 years has caused changes in climate and hydrology. The ...

  • A multi-method comparison of Atchafalaya basin surface water organic matter samples

    Received for publication January 29, 2008. Surface water organic matter (OM) was isolated from two distinct sites within the Atchafalaya Basin using a combination of XAD-8 and XAD-4 non-ionic macroporous resins and characterized by a suite of analytical methods, including elemental analysis, 13C cross polarization magic angle spinning nuclear magnetic resonance, attenuated total reflectance ...

  • Hydrologic impacts of climate change and urbanization in the Las Vegas Wash Watershed, Nevada

    A cell-based model for the Las Vegas Wash Watershed in Clark County, Nevada, USA, was developed by combining the Thornthwaite water balance model and the Soil Conservation Survey's Curve Number method with pixel-based computing technology. After the model was validated, it was used to predict the 2030 and 2050 hydrologic conditions under future scenarios of climate and land-use changes. The ...

  • Characterizing long-term Hydrologic-response and sediment-transport for the R-5 catchment

    Recently there have been several calls to establish long-term data collection networks to monitor near-surface hydrologic response and landscape evolution. The focus of this paper is a long-term dataset from the International Hydrologic Decade (1965–1974). The small upland catchment, known as R-5, located near Chickasha, Olahoma, has been the subject of considerable attention within the ...

  • Sensitivity analysis of climate change impact on the hydrology of the Litani Basin in Lebanon

    The effects of climate change on the surface water of the Litani Basin (Lebanon) are examined. A series of 82 hypothetical scenarios are imposed on each of the sub–basins' precipitation and temperature data and an integrated hydrological model is developed while conserving the other climate variables. A sensitivity analysis approach is applied to examine the relative changes of runoff from the ...

    The Pageru River basin is situated in drought prone areas of the Rayalaseema region, Andhra Pradesh, South–India. In the absence of perennial surface water bodies, groundwater is an important source of water and has played an important role in developing industry, agricultural and domestic supply. In the present study, the efforts have been made to assess the groundwater resources using both ...
