Case Studies of Applying Urban Surface Data in Evaluating Stormwater Management Issues
Urban runoff impervious surfaces suspended solids stormwater management non-point source pollution
2015/8/13
Pollutant load estimation is often required to evaluate stormwater management issues associated with water quality and urban development. Land use (e.g. residential, commercial) is commonly employed a...
Surface water potential of the river Osun at Apoje sub-basin Nigeria
streamflow gauge heights Apoje sub-basin
2015/2/3
In order to archive the millennium goals of which water for all by the year 2015 is a major component; all efforts must be made to efficiently utilise the available water resources in various parts of...
Global land-surface evaporation estimated from satellite-based observations
Global land-surface satellite-based observations evaporation estimated
2011/3/14
This paper outlines a new strategy to derive evaporation from satellite observations. The approach uses a variety of satellite-sensor products to estimate daily evaporation at a global scale and 0.25 ...
A comparison of ASCAT and modelled soil moisture over South Africa，using TOPKAPI in land surface mode
ASCAT modelled soil moisture South Africa TOPKAPI land surface mode
2010/4/7
In this paper we compare two independent soil moisture estimates over South Africa. The first estimate is a Soil Saturation Index (SSI) provided by automated real-time computations of the TOPKAPI hydr...
The Two-layer Surface Energy Balance Parameterization Scheme (TSEBPS) for estimation of land surface heat fluxes
Two-layer Surface Energy Balance Parameterization Scheme (TSEBPS) estimation land surface heat fluxes
2010/4/7
A Two-layer Surface Energy Balance Parameterization Scheme (TSEBPS) is proposed for the estimation of surface heat fluxes using Thermal Infrared (TIR) data over sparsely vegetated surfaces. TSEBPS is ...
Less rain,more water in ponds:a remote sensing study of the dynamics of surface waters from 1950 to present in pastoral Sahel (Gourma region,Mali)
rain remote sensing study dynamics of surface waters pastoral Sahel
2010/2/20
Changes in the flooded area of ponds in the Gourma region from 1950 to present are studied by remote sensing, in the general context of the current multi-decennial Sahel drought. The seasonal and inte...
Relating surface backscatter response from TRMM precipitation radar to soil moisture:results over a semi-arid region
surface backscatter response TRMM precipitation radar soil moisture
2010/2/20
The Tropical Rainfall Measuring Mission (TRMM) carries aboard the Precipitation Radar (TRMMPR) that measures the backscatter (σ°) of the surface. σ° is sensitive to surface soil moisture and vegetatio...
Quantification of tillage,plant cover,and cumulative rainfall effects on soil surface microrelief by statistical,geostatistical and fractal indices
tillage plant cover cumulative rainfall effects soil surface microrelief
2009/11/2
Changes in soil surface microrelief with cumulative rainfall under different tillage systems and crop cover conditions were investigated in southern Brazil. Surface cover was none (fallow) or the crop...
PROCEDURES FOR EVALUATING THE SURFACE WATER BALANCE OF GRAN CANARIA
PROCEDURES SURFACE WATER BALANCE GRAN CANARIA
2009/10/29
To evaluate the surface water balance in Gran Canaria, standard procedures
were modified to fit local conditions, taking into account the availability
and quality of data as well as the special feat...
Estimation of Parameters of a Uniformly Nonlinear Surface Runoff Model
Estimation of Parameters Uniformly Nonlinear Surface Runoff Model
2009/10/29
The surface runoff model, based on the concept of uniform nonlinearity
(Dooge 1967), has three parameters. It is shown that these parameters can be
estimated from the informaion that can be easily o...
Snow Surface Measurements from Digital Landsat MSS Data
Snow Surface Measurements Digital Landsat MSS Data
2009/10/28
The snow cover is an important parameter for water run-off prediction in high
mountain areas. At present its seasonal changes can be monitored regularly by
satellite. The paper presents a new method...
Simulation of Surface Runoff and Pipe Discharge from an Agricultural Soil in Nothern Sweden
Surface Runoff Pipe Discharge Agricultural Soil Nothern Sweden
2009/10/27
In order to test the ability of a physically based water and heat model to predict
surface runoff and pipe discharge, adaptations were made to an agricultural
field in the north of Sweden. A five-ye...
A desk-top method based on kinematic overland flow and Green-and-Ampt infiltration models is developed to determine the time of concentration of and the peak runoff rate from a converging basin. The g...
