Assessment of Spatial Patterns of Sediment Transport and Delivery for Soil and Water Conservation Programs
off-site soil erosion soil erosion deposition model
2015/8/14
Soil erosion has tremendous impacts on most river systems throughout the United States. Such non-point pollution results from land-use and agricultural practices and leads to sedimentation downstream,...
Estimating Spatial Sediment Delivery Ratio on a Large Rural Catchment
soil erosion sediment yield sediment delivery ratio modelling
2015/8/11
Soil erosion and sediment yield from catchments are key limitations to achieving sustainable land use and maintaining water quality in streams, lakes and other water bodies. Controlling sediment loadi...
Hydrology and Water Balance of Devils Lake Basin: Part 2 - Grid-Based Spatial Surface Water Balance Modeling
water balance Devils Lake remote sensing Geographic Information System
2015/8/11
In this part of the study, grid-based spatial water balance approach was used to estimate the annual water balance of Devils Lake basin, hydrologically closed lake located in the Red River of the Nort...
Spatial Variability of Groundwater Recharge - II. Factors Affecting Variability and Taking Account of it in Estimating Recharge
Spatial variability Groundwater recharge Sri Lanka
2015/8/6
The accompanying paper provided evidence to suggest that spatial variability of groundwater recharge is ‘true’ variability. This paper attempts to determine the major causes of such variability even a...
Spatial Variability of Groundwater Recharge - I. Is it really variable?
Spatial variability Groundwater recharge Sri Lanka
2015/8/6
The spatial variability of recharge is an important consideration in estimating recharge especially as all methods of estimating it are 'point' estimates and in most places recharge varies in space. T...

Spatial and Tidal Variations of Physico-Chemical Parameters in the Lower Gangetic Delta Region, West Bengal, India
spatial variation tidal condition Hooghly estuary
2015/1/9
The lower stretch of Gangetic delta in the Indian sub-continent is noted for its rich mangrove biodiversity, natural calamities, and livelihood-supporting matrix of millions of people and is the only ...
A Spatial Technique for Estimating Streambank Erosion Based On Watershed Characteristics
watershed modeling streambank erosion sediment transport
2015/1/4
A GIS-based technique was developed for estimating streambank erosion rates for more accurately predicting total sediment loads at the watershed scale without the use of detailed field data. This tech...

Spatial uncertainty assessment in modelling reference evapotranspiration at regional scale
evapotranspiration regional scale
2010/12/22
Evapotranspiration is one of the major components of the water balance and has been identified as a key factor in hydrological modelling. For this reason, several methods have been developed to calcul...
Spatial decisions under uncertainty:fuzzy inference in urban water management
Spatial decisions under uncertainty fuzzy inference urban water management
2009/12/4
The endogenous complexity and spatial nature of the problems encountered in the urban water management environment present decision-makers with three major problems: (a) in the urban environment, ever...

Spatial dependences among precipitation maxima over Belgium
Spatial dependences precipitation maxima Belgium
2009/11/3
For a wide range of applications in hydrology, the probability distribution of precipitation maxima represents a fundamental quantity to build dykes, propose flood planning policies, or more generally...
How much does inclusion of non-linearity and multi-point pattern recognition improve the spatial mapping of complex patterns of groundwater contamination?
inclusion of non-linearity multi-point pattern recognition spatial mapping complex patterns
2009/10/30
In this brief communication, we discuss the implication of the hypothesis that "non-linearity and multi-point pattern recognition can improve the spatial mapping of complex patterns of groundwater con...
